Abstract:
The purpose of this research is the creation of the framework for immersive Virtual Worlds (VW) development and evaluation of factors affecting user’s immersion experience in 3D virtual worlds. Three experiments have been conducted to evaluate different aspects of the immersion experience in virtual reality. The first experiment aimed to explore the influence of communication on users whilst performing certain activities in a virtual world. The second experiment evaluated how the real-world environment affects users in a virtual world. The third experiment examined the aspect of mobility as a main contributor to a user’s distraction. The fourth experiment partly confirmed previous findings and added new factors, affecting immersion experience. The results of all experiments formed a framework, containing factors which users considered as affecting them during their activities in virtual worlds. During the experimentation phase of this research a combination of qualitative and quantitative methods was used. The Grounded Theory (GT) methodology was applied for data analysis in qualitative part. The major contribution of this research is the framework of factors for building immersive 3D virtual environments. Another contribution is the evaluation of factors affecting users in such an environment.

Abstract:
Centralt inom Virtual Reality är upplevelsen att det digitala uppfattas som verkligt. Men varför känns just den här upplevelsen verklig? Genom att undersöka flera olika perspektiv på Virtual Reality, verklighet och nedbrytningar av begrepp inom tidigare Virtual Reality-forskning sökte vi att se hur denna verklighetskänsla uppstod, och kunde användas, inom Virtual Reality-spel. Genom ett gestaltningsarbete som fokuserade på olika typer av scener och kontrollsystem strävade vi mot att föra en diskussion om de olika teoriernas praktiska applikation.Central to Virtual Reality is the experience of the digital as the real. But from where does this experience stem? By investigating several different perspectives on Virtual Reality, reality and deconstructions of concepts in previous Virtual Reality-science we’ve looked into the creation of this sensation of reality in Virtual Reality-games. Through a practical project, focusing on different types of scenes and control schemes, we then sought to create a discussion focusing on the practical application of the differing theories.

Perroud, Benoit. "Immersion visuelle réaliste : proposition d'un modèle d'évaluation." Thesis, Paris, ENSAM, 2018. http://www.theses.fr/2018ENAM0060/document.
Abstract:
La thèse « Immersion visuelle hyper-réaliste et multi-sensorielle 3D » a été réalisée dans le cadre d’un contrat CIFRE établi entre les Arts et Métiers d’une part et Renault SAS d’autre part. Elle propose un modèle de score permettant d’évaluer objectivement de la capacité d’un système d’affichage immersif à reproduire le bon niveau de stimulation sensorielle pour un utilisateur, par rapport à ce qu’il recevrait dans la réalité et à la modélisation du système visuel humain.Dans un premier temps nous nous sommes intéressé à poser les bases du modèle : celui-ci est composé de douze critères, répartis équitablement en une somme d’indices de vision et d’indices d’immersion. Chaque critère se voit attribuer, dans la mesure du possible, une note de 0 à 100. La note de 0 représente l’incapacité du système visuel à percevoir ou à utiliser les informations visuelles, tandis que la note de 100 incarne la capacité maximale.Une note de 80 est également assignée pour la performance standard. Chaque critère se voit assigner une pondération en fonction de la tâche réalisée en environnement virtuel. Nous réalisons dans un second temps une série d’expérimentations afin de compléter les informations disponibles dans la littérature, pour l’établissement des critères. On s’intéresse plus particulièrement au contraste et à la latence. La première expérimentation consiste en la transposition et la validation d’un modèle de performance visuelle en Réalité Virtuelle. Dans la seconde, on compare les effets de la latence sur une tâche donnée, entre un simulateur de type CAVE et un casque de Réalité Virtuelle.La thèse propose un certain nombre de résultats tant théoriques et méthodologiques qu’expérimentaux. En condition d’immersion virtuelle, les critères de contraste et de luminance sont importants pour la perception visuelle. Les expériences réalisées montrent qu’un modèle adapté aux conditions d’immersion virtuelle est nécessaire. Par ailleurs, on montre que des seuils d’influence de la latence sur la performance semblent exister. On vérifie également la pertinence de corrélations entre performance, présence et mal du simulateur, en fonction de la latence et du système immersifThe thesis "Hyper-realistic and multi-sensorial 3D visual immersion" was carried out within the framework of a CIFRE contract established between Arts et Métiers on the one hand and Renault SAS on the other. It proposes a score model to objectively evaluate the ability of an immersive display system to reproduce the right level of sensory stimulation for a user, compared to what he would receive in reality and to the modeling of the human visual system.First, we were interested in laying the foundations of the model: it is composed of twelve criteria, equitably divided into a sum of vision indices and immersion indices. Each criterion is given, as far as possible, a score from 0 to 100. A score of 0 represents the visual system’s inability to perceive or use visual information, while a score of 100 represents maximum capacity. A score of 80 is also assigned for standard performance. Each criterion is assigned a weight according to the task performed in the virtual environment.We then carry out a series of experiments to complete the information available in the literature, to establish the criteria. Contrast and latency are of particular interest. The first experiment consists in the transposition and validation of a visual performance model in Virtual Reality. In the second, we compare the effects of latency on a given task, between a CAVE simulator and a HMD.The thesis proposes a number of theoretical, methodological and experimental results. In virtual immersion conditions, contrast and luminance criteria are important for visual perception. Experiments show that a model adapted to virtual immersion conditions is necessary. Furthermore, we show that thresholds of latency influence on performance seem to exist. The relevance of correlations between simulator performance, presence and cyber-sickness is also checked, depending on the latency and the immersive system

Abstract:
Det här arbetet har som mål att undersöka huruvida tillägget av Virtual reality-teknologi i form av en Head mounted display (HMD) har någon påverkan på en spelares känsla av immersion i ett spel som använder sig av ett tredjepersonsperspektiv. För att kunna undersöka detta togs en frågeställning fram. För att undersöka denna frågeställning så utfördes en kombinerad kvantitativ/kvalitativ studie där 16 deltagare indelade i två grupper fick spela en kort prototyp framtagen för studien. Den ena gruppen spelade igenom prototypen med en HMD och den andre spelade utan. Data samlades in genom en enkät samt observationer och en kort intervju. Resultaten från de två grupperna samanställdes efter testerna för att få fram ett medelvärde för gruppens upplevda immersion. Dessa medelvärden jämfördes sedan med varandra. Resultatet av detta tyder på att tillägget av en HMD ökar användarens känsla av immersion om samtliga andra variabler är desamma.

Abstract:
The goal of this thesis is to present the virtual environments research community with a thorough investigation of collaborative awareness in Tele- immersion and related immersive virtual environments. Tele-immersion was originally defined in 1996 by Tom Defanti of the Electronic Visualization Laboratory (EVL), is "the union of networked VR and video in the context of significant computing and data mining" [Leigh, et. al., 1997]. Since then, research on Tele-immersion has outgrown most of its system and performance-related issues and now focuses supporting collaborative interaction and usability. Tele-immersion now deals with the "[creation of persistent virtual environments] enabling multiple, globally situated participants to collaborate over high-speed and high-bandwidth networks connected to heterogeneous supercomputing resources and large data stores" [Leigh, et. al., 1997, p. 1 of 9].
In the early stages of Tele- immersion there were two main factors driving the research: the significant processing load of real-time and simulated computational steering, and the sheer bulk of the data sets being generated for scientific visual analysis [Leigh, et. al., 1997]. Now the growing number of immersive VR sites is motivating a need to support human-to-human interaction and work over wide networks of immersive virtual environments. This research focuses heavily on issues of collaborative awareness in these networked, immersive virtual environments. Collaborative awareness, in this context, is a concept that encompasses the caveats of one's knowledge about the CVE and its occupants. As a result of this study, software has been designed to provide support not only for collaborative awareness, but also for several other dimensions of collaboration.Master of Science

Abstract:
We present an early exploration of in-game advertising for virtual reality games. The study investigates what the impacts of interactivity and immersion on consumer learning and game experience are. First, we establish a theoretical grounding for understanding interactivity and immersion in virtual gaming environments. Then, we form a research framework and propose hypotheses around the research question. Next, we report the results of the field research, prototype design, and user study. The prototypes run in mobile browsers and are tested on virtual reality goggles with smartphones attached. Based on the results, we discuss the design of interactivity and immersion, the design’s impacts on consumer learning and game experience as well as the correlation between game experience and consumer learning. The main contributions of the work are an original research framework and a set of design considerations that can be utilized to evaluate and improve the effectiveness of in- game advertisements for virtual reality games.Vi presenterar en tidig utforskning av reklam i spelet för virtuell verklighet-spel.

Abstract:
This dissertation uses Heidegger’s critique of technology and its essence in an attempt to understand how Virtual Reality technology can change how we interact with the world and each other. The history of VR devices is unpacked to understand the motivation behind VR’s uses and development. Merleau-Ponty’s theories about embodied experiences are also used to understand how VR has an increased capacity to generate a sense of telepresence in the virtual environment for the user. Cases are investigated that specifically deals with how VR has influenced human interactions and rituals and made them more convenient to the users.
The first cases focus on religion and how it changes when it is taken online. Specific focus is given to the Church of Fools online church and D.J. Soto’s VR church. The difference between how an online church operates is compared to the VR Church and how embodiment in the VE is experienced in each. This dissertation also explores cases where a user enters a ‘cross-dimensional’ relationship with the virtual. Two cases of people marrying virtual characters are examined. In these cases, the user entered a relationship with a character that was constructed by someone else. The other case examined, is that of Sgt.Hale (username) who created and then married a virtual character in a VE that he designed and based on a real-world location. In each of the relevant cases, how technology has influenced and, in a sense, encouraged them, is explored and unpacked.Dissertation (MA)--University of Pretoria, 2020.

Pereswetoff-Morath, Alexander. "THE OCULUS RIFT’S EFFECTS ON IMMERSION SURROUNDINGMORAL CHOICE : A study of modern VR technology and itseffects on a user’s spatial immersion in avirtual environment." Thesis, Högskolan i Skövde, Institutionen för informationsteknologi, 2014. http://urn.kb.se/resolve?urn=urn:nbn:se:his:diva-10013.
Abstract:
This report is about VR and the effects the VR technology Oculus Rift may or may not have on the different kinds of immersion possible in virtual environments, or games. The report is based on the premise that modern games have evolved into more story based adventures with better graphics, often with moral choice as gameplay, and theories regarding new mediums and the dangers of not fully understanding them. It is also done in cooperation with a research team at Högskolan i Skövde, with a focus on moral dilemmas, and is using a virtual environment to test this combined effort. The game engine Unity is used to create a realistic environment and together with the Oculus Rift, is testing what kinds of effects the VR technology has on the users. 20 test participants have shared their experiences and the majority, independent of gaming experience, claims it has a positive effect.

Harman, Joel. "Exploring the effect of visual immersion during procedural knowledge elicitation within virtual reality." Thesis, Queensland University of Technology, 2020. https://eprints.qut.edu.au/180842/1/Joel_Harman_Thesis.pdf.
Abstract:
Accurately recalling and describing information is challenging. This research focusses on a new approach, which aims to help people impart knowledge of past activities and events, by role-playing their memory of a prior experience within a related virtual environment. By providing virtual stimuli and context relevant to the original experience, people were able to better recall and describe information. Further consideration of the visual presentation was explored. The result was that while a more immersive experience provided by a virtual reality headset can help people better recall information, the visual detail of the environment may not be so important.

Abstract:
I denna studie undersöks sambandet mellan visuella och taktila stimuli i Virtual Reality med avstamp i frågeställningarna: Hur stor roll spelar sambandet mellan visuella stimuli och taktila stimuli i en Virtual Reality-installation? Hur förändras deltagarens inlevelsekänsla när detta samband ändras? Hur förändras deltagarens rumsuppfattning när detta samband ändras? För att besvara frågeställningarna skapades två olika versioner av en interaktiv VR-installation utefter metoden forskning genom design. En av versionerna hade korrekt samband mellan visuella stimuli och taktila stimuli, det vill säga att deltagaren fysiskt kunde röra vid det denne såg med hjälp av fysiska objekt som var placerade i samma rum som installationen upplevdes i. Den andra versionen hade felaktigt samband mellan visuella stimuli och taktila stimuli, vilket innebar att de fysiska objekten hade flyttats en aning i Virtual Reality-installationen så att de ej speglade objekten i verkligheten. Det vill säga att informationen deltagaren avläste vid beröring ej stämde överens med informationen deltagaren avläste med synen. Därefter fick fyra deltagare testa dessa installationer och svara på frågor i en öppen intervjuform. Resultatet kopplades tydligt till Csíkszentmihályis flow-teori; när sambandet mellan dessa stimuli ej var korrekt så förändrades deltagarnas rumsuppfattning vilket bidrog till att de kände en lägre inlevelsekänsla. Möjligheten att kunna vidröra de fysiska objekten i sig ansågs dock som mer inlevelserikt än ifall möjligheten ej funnits där. Det ses även som styrkan med denna studie; att resultatet tydligt speglade de valda teorierna. Svagheten med studien var att resultatet enbart grundas på data från intervjuer med fyra deltagare, då flera ej hanns med inom tidsramen för studien.

Abstract:
Virtual Reality (VR) can potentially transport the user to another world. Outside of VR, musical soundtrack is usually placed outside of the scene, referred to as non-diegetic sound. In VR, this could potentially break immersion. Other ways to implement music have to be tested. A test was created consisting of three scenes with a wide selection of “listening modes”, or musical configurations. The listening modes ranged from non-diegetic stereo music via headphones to diegetic, played from speakers inside the VR spaces. 10 respondents played through the scenes in VR, experiencing every listening mode. Respondents then replied to a questionnaire gathering their thoughts on their experience. Results showed that immersion improved the more the experience corresponded to expectations from outside of VR. Non-diegetic listening modes were considered less immersive than diegetic listening modes. This study lays a basic foundation for further research on music in VR with initial guidelines for proper implementation.

Abstract:
Modern virtual reality is an ever growing subject in today’s society. I delved deeper into some key moments in the development of modern virtual reality. Oculus Rift has shown incredible potential. Some developments even seek to envelope the human senses in virtual reality as well. With several different approaches to the same solution there are many ways that the experience can affect the overall immersion of a consumer into the product. The tests I performed were primarily focused around the interaction between the human senses and immersion. The immersion can be increased or decreased by basic means of stimulating the human senses. This test was implemented by having volunteers participate in two phases in a supervised environment. In the first phase, the participants were subjected to an increase in immersion by stimulating senses other than their eyes and ears. The second phase involved reducing the participants’ sensory stimulation to see what the difference in immersion would be between the two phases. The results of the investigation show that manipulating the human senses does have an impact on immersion when using virtual reality. Immersion can be affected by increasing or decreasing the stimuli for the human senses.

Abstract:
My research into Virtual Reality technology and its central property of immersion has indicated that immersion in Virtual Reality (VR) electronic systems is a significant key to the understanding of contemporary culture as well as considerable aspects of previous culture as detected in the histories of philosophy and the visual arts. The fundamental change in aesthetic perception engendered by immersion, a perception which is connected to the ideal of total-immersion in virtual space, identifies certain shifts in ontology which are relevant to a better understanding of the human being. This understanding was achieved through a broad inquiry into the histories of Virtual Reality, philosophy, and the visual arts and has lead to the formulation of an aesthetic theory of immersive consciousness indicative of immersive culture. The primary subject of this discourse is immersion then: an experience which will be identified within the dissertation as the indispensable characteristic of Virtual Reality. The understanding of immersion arrived at here will be used to fashion a synchronous theory of art particularly informed by encounters and concepts of immersion into virtuality. To sufficiently address this subject in a scholarly fashion, I have researched, found and accumulated aesthetic and philosophic examples of immersive tendencies, as found within the histories of art and philosophy, which subsequently contributed towards the articulation of what I have come to call immersive consciousness. As a result of formulating such an immersive consciousness, a good deal of the basis for the questioning of the Western ontological tradition has been found in the Western tradition itself when we look with new eyes and ask new uncertain questions. Moreover, this immersive consciousness will be used to propose some abstract questions encircling today's electronic-based culture. Through the structuring of the argument within the thesis - and overtly within the conclusion -1 have articulated a non-teleological creative strategy which provides the basis for an unconstraining integration of noologies (ways of semblancing the thinking process). This strategy provides a means of exemplifying - and for honoring - various methods of thinking. This structuring strategy is consistent with the 'hacker ethic' as defined by Steven Levy, as a demand that access to computers - and anything which might teach us something about the way the world works - should be unlimited and total. To follow this strategy, this dissertation has set out to understand how topical conceptions of virtual immersion connect to pre-existing systems of thought as revealed in art as they have extended out of antecedent ontological self-understands, historical human self-understands which have evidenced themselves in the elaboration of technological objectives. To do this I have forged a certain rhizomatic paternity/maternity for Virtual Reality within this dissertation by joining choice immersive examples of simulacra technology into mental connections with the relevant examples culled from the histories of art, architecture, information-technology, sex, myth, space, consciousness and philosophy.

Abstract:
Virtual Reality har existerat i olika former runt 80 år tillbaka, men i dess nuvarande form har den en mer signifikant plats på marknaden. Med detta behövs mer forskning på hur VR fungerar och hur människor påverkas av VR för att kunna utveckla produkter till detta växande medium. Forskningen är idag bristande, så för att bredda förståelsen om VR och framförallt VR som konsol för spel har den här kvalitativa studien undersökt hur skräckelement upplevs i en VR-miljö. Studien undersökte även vad som kan påverka “immersion”, fördjupning i miljön, samt om tidigare erfarenheter kan påverka upplevelser i en VR-miljö. Dessa frågor analyserades utifrån två speltest som gjordes på VR-konsolen HTC Vive. Första speltestet fokuserade på kontroller och “immersion” för att se hur pass lättförstådd och intuitiv konsolen är. Det andra testet undersökte skräckelement i VR och vad för slags element kunde bidra till en mer effektiv och intensiv skräckupplevelse. Totalt deltog 16 personer mellan 19-26 år i speltesterna. Deltagarna var studenter vid Karlstad Universitet eller hade tidigare varit det. Deltagarna blev indelade i olika grupper baserade på tidigare erfarenhet inom spel (första testet) och skräck (andra testet). Med hjälp av observation av videoinspelningar och intervjuer kunde den insamlade datan delas in i teman. De teman som användes för att analysera datan var kontroller, obehag/desorientering, “immersion” och skräckelement. Resultaten visade att HTC Vive har goda förutsättningar för “immersion”. Dock med några problematiska faktorer, utrustning exempelvis, som störde upplevelsen. Trots detta skapade konsolen en stark känsla av “immersion” då deltagarna upplevde sig närvarande i VR-miljön på grund av sådant som bakgrundsljud och naturligt perspektiv på VR-miljön i headsetet. Det som spelade störst roll för “immersion” var att miljön behövde agera verklighetstroget, alltså som spelaren förväntar sig. Den sortens närvaro bidrog positivt till skräckupplevelsen då spelarna tycktes uppleva sig hotade av skräckelementen som att det var riktat mot dem personligen och inte bara en karaktär i ett spel. Gällande skillnader mellan grupperna i erfarenhet fanns det inte många substantiella skillnader. Det kunde märkas lite skillnad i hur kontrollerna hanterades mellan de spelerfarna och icke erfarna. De med tidigare erfarenhet tycktes ha med sig förväntningar om hur kontrollerna skulle fungera. Studien hade, på grund av dess kvalitativa natur, inte möjlighet att få fram generaliserbara resultat. Dock så öppnade den upp för frågor till framtida forskning gällande både VR-spel och dess användare samt om VR-konsoler.Virtual Reality has existed in different forms since around 80 years ago, but in its current form it has a more significant place on the current market. With this change, more research on how VR works and how humans are affected by it is needed to be able to develop products for this growing medium. The research today is lacking, so to expand the understanding of VR and specifically VR as a console for games, this qualitative study has researched how elements of fear are experienced in a VR-environment. The study also studied what can affect “immersion”, depth in the environment, as well as if previous experience can affect experiences in a VR-environment. These questions were analyzed based on two game tests that were made on the VR-console HTC Vive. The first test focused on controls and “immersion” to see how intuitive and easily understood the console is. The second test examined horror elements in VR and what kinds of elements could contribute to a more effective and intense horror experience. A total of 16 people between the ages of 19-26 participated in the game tests. The participants were students at Karlstad University, or had previously been so. The participants were divided in different kinds of groups depending on previous experiences in digital games (the first test) and horror (the second test). With the help of observation of the video recordings and the interviews the collected data could be divided into themes. The themes used to analyze the data were controls, disorientation/discomfort, “immersion” and horror elements. The results showed that HTC Vive have good qualifications for “immersion”. Though with a few problematic factors, the equipment for example, which disturbed the experience. Despite this, the console created a strong feeling of “immersion” as the participants experienced themselves to be present in the VR-environment because of factors such as background noise and a natural point-of-view of the VR-environment through the headset. The biggest contributor for “immersion” was that the environment needed to have a natural and believable behavior, acting the way the user expects it to. This kind of presence contributed positively to the horror experience as the participants seemed to believe themselves to be threatened by the horror elements as if it was directed at them personally and not just a character in a game. In the subject of differences between the groups in experience there not a lot of substantial differences. A small difference could be found regarding how the controls were handled between the different groups of game experience. The participants with previous experience seemed to bring expectations about how the controls should work. The study had, because of its qualitative nature, no possibility to receive generalizable results. But the study did open up for questions for future research related to VR-games and their users, as well as VR-consoles.

Abstract:
Interactive TV in motorsport, specifically Formula 1, is an established service that has been developed over the last 20 years. Market research reveals trends in broadcasting pointing towards, in the future, sports, in general, will be consumed via VR. Broadcasting interactive TV with VR acting as the medium, however, is an unfamiliar territory where a gap in research exists in interaction design.The purpose of this thesis is to research the viewing habits of inexperienced and experienced viewers of F1 through empirical work that includes literature review, observation and interviews. The insights gathered are then conceptualized through workshops and sketching. These, in turn, helps produce a set of iterated prototypes that are usability tested to extract insights which reveal design recommendations for ergonomics and interface and elements for augmenting the viewing experience the designer should keep in mind when developing for VR broadcasted interactive motorsport TV.

Abstract:
Virtual reality (VR) technology has permeated consumer culture in recent years, consequentially inspiring a hotbed of interdisciplinary academic VR research to better understand its effects as a medium. It has become a popular subject of study in fields as varied as engineering, computer science, communication, and psychology. The present study evaluates methodological trends in behavioral research on VR in terms of best practices regarding data collection, reporting, and availability. A meta-scientific content analysis of 61 articles focused on power, p-values, reporting errors, and transparency of data, all of which respectively represent four stages of research: data collection, analysis, reporting, and sharing. The findings from 1,122 statistical tests show that there is room for improvement in much behavioral research on VR in terms of methodological trends regarding number of participants, reporting of results, and data availability. Although no firm conclusions can be drawn about the presence of p-hacking or other questionable research practices (QRPs), the present study demonstrates that chronically small sample sizes, instances of errors in reporting, and a lack of transparent supplemental data are evident. The trends observed are broad, yet informative, and further research in this area is crucial. Methodological recommendations are made for future research dealing with VR applications, particularly given the potential social and cultural impact of the technology.Master of Arts

Abstract:
Training is one of the most important and widely-used applications of immersive
Virtual Reality (VR). Research has shown that Immersive Virtual Environments (IVEs)
are beneficial for training motor activities and spatial activities, but it is unclear whether
immersive VEs are beneficial for purely mental activities, such as memorizing a
procedure. In this thesis, we present two experiments to identify benefits of immersion
for a procedural training process. The first experiment is a between-subjects experiment
comparing two levels of immersion in a procedural training task. For the higher level of
immersion, we used a large L-shaped projection display. We used a typical laptop display
for the lower level of immersion. We asked participants to memorize two procedures: one
simple and the other complex. We found that the higher level of immersion resulted in
significantly faster task performance and reduced error for the complex procedure. As
result of the first experiment we performed a controlled second experiment. We
compared two within-subjects variables namely environment and location under various
treatments formed by combination of three between-subject variables namely Software
Field Of View (SFOV), Physical FOV, Field Of Regard (FOR). We found that SFOV is
the most essential component for learning a procedure efficiently using IVEs. We
hypothesize that the higher level of immersion helped users to memorize the complex
procedure by providing enhanced spatial cues, leading to the development of an accurate
mental map that could be used as a memory aid.Master of Science

I nuvarande forskning så existerar det ett research gap inom ljudproduktion och ljuddesign för Virtual Reality-applikationer. Det finns en mängd teknisk forskning om uppspelning av spatialiserat ljud för virtual reality med tekniker som binauralt ljud, HRTF (head-related transfer functions) och ambisonics. Allt detta är av högsta grad relevant för denna undersökning och kommer att diskuteras kring samt redogöras för i senare del av artikeln, men kommer inte att ta en central del av undersökningen. Snarare är det avsaknaden av metoder och processer för det kreativa skapandet och implementeringen av ljud för Virtual Reality som intresserar den här undersökningen. Denna artikel tar ett initiativ för att framhäva vikten av en genomtänkt och väl utförd ljuddesign för Virtual Reality- applikationer samt redogöra för tankesätt och metoder som kan appliceras i en audiell designprocess. Detta genom analys utav fenomenen immersion och närvaro. Med denna analys som grund översätts dessa sedan till metoder och nyckelord som främjar att stödja skapandet av applikationers audiella innehåll. Undersökningen har mynnat ut i ett designobjekt som existerar som ett exempel för denna process och redogörs med en grundlig dokumentation. Artikeln avslutas med en jämförande studie där detta designobjekt placeras tillsammans med andra designexempel från marknaden i ett antecknande portfolio. Detta för att undersöka likheter mellan dessa exempel utifrån de nyckelord som kommer att framföras samt redogöras för i artikeln. Förhoppningen är att denna process kan tydliggöra för ljudets roll i att skapa en immersiv upplevelse samt inspirera andra ljuddesigners att applicera dessa metoder i dennes egna designprocess.In present research there exists a research gap within the field of sound production and sound design for virtual reality-applications. There is a ton of technical research to be found such as the deliverance of spatial audio for virtual reality through techniques like binaural audio, HRTF (head-related transfer functions) and ambisonics. All of these are highly relevant for this research and will be discussed in a later part of the article however they won't take a central part of the research process. It is rather the lack of methods and processes for the creative design and implementation of sound for virtual reality that this research finds interesting. This article takes an initiative to shed light on the importance of a well thought- through and properly executed sound design for Virtual Reality applications and gives an account for the thought process as well as methods that can be applied to an audio design process. This is done through an analysis of the phenomena known as immersion and presence. With the analysis as groundwork, the explanations of these phenomena then get translated to methods and keywords that support the creation of audio content for the given application. This research has formed the basis for a design object that exists as an example for this process and has been thoroughly documented along the way. The article ends with a comparative research study where this design object is placed together with other design examples from the general market in an annotated portfolio. The reason for this is to point out similarities through the lens of keywords that will be presented and explained in this article. This process sets out to clarify the role sound has in the creation of an immersive experience as well as to inspire other sound designers to apply these methods in their own design processes.

Abstract:
New technologies, such as virtual reality, often draw to itself myths from other fields of interest and discourses. One such myth that has attached itself to virtual reality is the notion that virtual reality can provide a utopia for the mind, or true self, if the body can be cast off. It is this discarding of the body that my thesis aims to investigate in terms of Girardian sacrifice. Girard?s notion of sacrifice is built upon the observation of various cultures throughout history. It stands to reason that in our contemporary, digitally influenced, society, sacrifice, in some form, still persists. I argue that the body, when viewed as disposable, through the use of virtual reality, exhibits the same traits as the selected sacrificial victim. As the myth of a utopia for the mind, or true self, exists prior to the advent of virtual reality, traces of it, as well as the sacrifice I argue it entails, can be found in other texts as well. One such a text is The Chrysalids (Wyndham 1955). This text presents the reader with characters which I argue represent both the mind and body separately. The Chrysalids culminates in the characters representing the mind leaving for a utopian city whilst the character who, I argue, is most strongly associated with the body, Sophie Wender, is killed. It is also argued here in that the notion of abandoning the body is simply a myth since the inability to abandon the body is also discussed in terms of phenomenology, pointing out that the body can ultimately not be completely removed from the making of meaning. This phenomenological acknowledgement of the body, along with a critique The Chrysalids and cyber-utopia?s view of the body, forms the basis of my practical body of work.Dissertation (MA)--University of Pretoria, 2016.

Abstract:
People call the year of 2016 as the year of virtual reality. As the world leading tech giants are releasing their own Virtual Reality (VR) products, the technology of VR has been more available than ever for the mass market now. However, the fact that the technology becomes cheaper and by that reaches a mass-market, does not in itself imply that long-standing usability issues with VR have been addressed. Problems regarding motion sickness (MS) and motion control (MC) has been two of the most important obstacles for VR technology in the past. The main research question of this study is: “Are there persistent universal access issues with VR related to motion control and motion sickness?” In this study a mixed method approach has been utilized for finding more answers related to these two important aspects. A literature review in the area of VR, MS and MC was followed by a quantitative controlled study and a qualitative evaluation. 32 participants were carefully selected for this study, they were divided into different groups and the quantitative data collected from them were processed and analyzed by using statistical test. An interview was also carried out with all of the participants of this study in order to gather more details about the usability of the motion controllers used in this study. The results of this study has validated several existing frameworks for VR. And in conclusion, this study has also shown that both previous motion sickness experiences and gender factors weren’t significant in terms of general accessibility issues on PCVR platforms. There are hints showing that the VR technology on PC platform could be universal accessible, since both of the quantitative and qualitative results has provided some evidences supporting this finding. However, more similar studies need to be carried out in order to identify more possible factors that would give an impact on user experiences in VR. The results of this study has also given implications of that today’s VR technology is developing on the right track and it could slowly become adopted by the mainstream and mass-market in the future.

Abstract:
This dissertation provides empirical evidence for the effects of the fidelity of VR system components, and novel 3D interaction techniques for analyzing volume datasets. It provides domain-independent results based on an abstract task taxonomy for visual analysis of scientific datasets. Scientific data generated through various modalities e.g. computed tomography (CT), magnetic resonance imaging (MRI), etc. are in 3D spatial or volumetric format. Scientists from various domains e.g., geophysics, medical biology, etc. use visualizations to analyze data. This dissertation seeks to improve effectiveness of scientific visualizations.
Traditional volume data analysis is performed on desktop computers with mouse and keyboard interfaces. Previous research and anecdotal experiences indicate improvements in volume data analysis in systems with very high fidelity of display and interaction (e.g., CAVE) over desktop environments. However, prior results are not generalizable beyond specific hardware platforms, or specific scientific domains and do not look into the effectiveness of 3D interaction techniques.
We ran three controlled experiments to study the effects of a few components of VR system fidelity (field of regard, stereo and head tracking) on volume data analysis. We used volume data from paleontology, medical biology and biomechanics. Our results indicate that different components of system fidelity have different effects on the analysis of volume visualizations. One of our experiments provides evidence for validating the concept of Mixed Reality (MR) simulation.
Our approach of controlled experimentation with MR simulation provides a methodology to generalize the effects of immersive virtual reality (VR) beyond individual systems. To generalize our (and other researchers') findings across disparate domains, we developed and evaluated a taxonomy of visual analysis tasks with volume visualizations. We report our empirical results tied to this taxonomy.
We developed the Volume Cracker (VC) technique for improving the effectiveness of volume visualizations. This is a free-hand gesture-based novel 3D interaction (3DI) technique. We describe the design decisions in the development of the Volume Cracker (with a list of usability criteria), and provide the results from an evaluation study. Based on the results, we further demonstrate the design of a bare-hand version of the VC with the Leap Motion controller device. Our evaluations of the VC show the benefits of using 3DI over standard 2DI techniques.
This body of work provides the building blocks for a three-way many-many-many mapping between the sets of VR system fidelity components, interaction techniques and visual analysis tasks with volume visualizations. Such a comprehensive mapping can inform the design of next-generation VR systems to improve the effectiveness of scientific data analysis.Ph. D.

Abstract:
This study examined how reduced control-display ratios on motion-tracked handheld controllers in virtual reality affected user immersion and sense of control. 24 participants played a puzzle game in virtual reality using one of three control-display ratios: one normal, and two that were reduced using the “Go-Go” technique. Results indicate that the control-display ratio can be reduced drastically while retaining user immersion and sense of control, but that the effectiveness of this seems to differ between individuals and is heavily influenced by previous experiences. Even so, these results could be of use for future virtual reality interaction designers as well as researchers studying the senses of vision and proprioception.Den här studien undersökte hur sänkta control-display-förhållanden på handhållna kontroller i virtual reality påverkade användares inlevelse och upplevda kontroll. 24 deltagare spelade ett pusselspel i virtual reality med en av tre control-display-förhållanden: en normal, och två som var sänkta med "Go-Go"-metoden. Resultaten indikerar att control-display-förhållandet kan sänkas markant utan att förlora användarens inlevelse eller upplevda kontroll, men till vilken grad detta sker tycks variera mellan individer och även påverkas av tidigare erfarenheter. Trots detta kan dessa resultat vara till nytta för framtida interaktionsdesigners i virtual reality samt för forskare som studerar sinnena syn och proprioception.

It is known that film, like all other arts, is influenced by technological advances. These influences inevitably modify film language. Today, the most obvious and visible interference of digital media on film lies in the possibilities of special effects that these new "tools" bring to the seventh art. However, my object of research has not turned towards that direction, but instead it was directed towards questions concerning the future of cinema, the possibilities of its language introduced by digital media, and especially for the creation of new forms of perception proper to interactive immersive environments. Although this question corresponds to a contemporary state of the art due to the explosion, followed by the consolidation of digital devices in the XXI century, in fact, it has already been studied and experimented since the 1970s and 1980s in the theoretical work of researchers such as Lev Manovich, Bill Seaman, Arlindo Machado, Peter Weibel, Peter Lunenfeld, Jeffrey Shaw, among others. They were all taken as the main sources for my discussions. The trends, which are many, and have received various designations in the direction of a possible future cinema, were discussed in chapter 2. Among them, the one that was studied more closely, that is, the conditions of immersion and the new narrative forms that they introduced, was the object of study of chapter 3. As a basis for these two chapters, chapter 1 discussed the roots of these present trends. These are to be found in experimental cinema and its enfolding along time whose consequences culminated in what, among other names, is being called future cinema
Sabe-se que o cinema, como todas as demais artes, sofreu e sofre influência dos avanços tecnológicos, influências estas que inevitavelmente modificam sua linguagem. Hoje, a interferência mais óbvia e visível que se tem das mídias digitais para/com o cinema encontra-se nas possibilidades de efeitos especiais que essas ferramentas trazem à sétima arte. No entanto, meu objeto de pesquisa não seguiu em tal direção, mas voltou-se para questões relativas ao futuro do cinema, às possibilidades de linguagem introduzidas pelas mídias digitais e, principalmente, para as novas criações perceptivas em ambientes imersivos interativos. Esta questão, apesar de corresponder a um estado da cinematografia atual e de ter sido conceituada a partir da explosão, seguida da consolidação dos aparatos digitais no século XXI, na realidade, já vem sendo estudada e experimentada desde a década de 1970/80, nos trabalhos teóricos de pesquisadores como Lev Manovich, Bill Seaman, Arlindo Machado, Peter Weibel, Peter Lunenfeld, Jeffrey Shaw, entre outros que serviram de base para as discussões realizadas. As tendências, que não são poucas, daquilo que vem recebendo várias designações na direção de um possível cinema do futuro, foram discutidas no capítulo 2. Entre elas, aquela que estudei mais de perto foi a da imersão e das novas condições narrativas por ela introduzida, objeto de estudo do capítulo 3. Como base para esses dois capítulos, o capítulo 1 discorreu sobre as raízes das tendências presentes. Estas se encontram no cinema experimental e seus desdobramentos que vieram desembocar na contemporaneidade naquilo que, entre outros nomes, está sendo chamado de cinema do futuro

Abstract:
This thesis examines two works from different mediums, the short story “How to Tell a True War Story” by Tim O’Brien and the video game Battlefield 1, to compare how each constructs empathy using virtual reality and mimetic communication between audience and the work. The thesis draws from both digital media studies and affect theory to construct a nuanced view of how empathy functions in the works. The body responds to empathy physically. As social creatures, humans feel the emotions of those around them, even if those around them are virtually constructed. In other words, the thesis will explore how video games have been used historically and what their effects are on gamers, especially gamers’ bodies and emotional responses to the constructed virtual reality. This work aims to show how the lines of fiction and reality become blurred to establish empathy within a narrative and virtual reality space.

Abstract:
Our goal was to create an enhanced spectator experience to better engage the rapidly growing audience for Esports, through the use of Virtual Reality (VR) technology. In this study, we delve into the ways in which VR can do this. To test this hypothesis, we created a VR spectator add-on for a game and gathered data using semi-structured interviews. The data from the interviews were then analyzed using thematic analysis. The results of our study show that VR provides more engagement through a combination of possible factors including proximity to the action, novelty of VR experiences and the harder controls in VR. The results also show that the terms "immersion" and "spatial presence" were quite possibly used interchangeably by the participants and also that there may not be a correlation between the terms "engagement" and "spatial presence". In conclusion, we believe that the increased sense of engagement through VR technology can be taken even further and has the potential to be something more than what traditional modes of spectating can offer.

Abstract:
In this project, the perception of distance and the degree of immersion in a game, with two different visualisation techniques, have been evaluated. A bicycle simulator was used, and the game has been tested in a non-immersive virtual reality, by projecting the game on a screen, and using an immersive virtual reality by Oculus Rift. The study provides a preliminary investigation that focuses on how humans can perceive the distance, an overview of the term immersion and how to quantify this component.Regarding the study of the perception of distance, to subjects who have tested the game has been asked their perceptions of distance with respect to a given object. The immersion was studied and evaluated using a questionnaire given to each subject.The results showed an underestimation of distance in both the visualisation of the game, precisely a greater underestimation respect to real distance when the screen was used was found.The degree of immersion did not detect large differences between the two visualisation techniques.

Abstract:
Virtuell verklighet (VR) har börjat användas i större utsträckning av människor inomområden som utbildning och underhållning. För att VR ska uppfattas som en seriösplattform för att skapa utbildnings- och underhållningstjänster, är en känsla avimmersion en viktig del av användarupplevelsen. Det finns idag olika metoder för attinteragera med VR men de saknar upplevelsen av att vara naturliga och realistiska.Handinteraktion anses vara ett naturligt sätt för människor att interagera med VR och harförutsättningar för att stödja immersion. Trots att handinteraktion anses vara ett bra sättatt interagera med VR finns det idag inga riktlinjer som underlättar för att designa tjänstermed handinteraktion. För att undersöka hur handinteraktion kan designas för att stödjaimmersion i VR, har vi utgått från frågan:Hur kan handinteraktion designas för virtuell verklighet för att stödja immersion?Genom vår studie har vi identifierat aspekter som är viktiga för att handinteraktion skastödja immersion. Frågan studeras genom en designorienterad ansats med kvalitativadatainsamlingsmetoder som deltagartester, intervjuer och observationer. Testdeltagarnasom deltagit i studien är rekryterade baserat på deras tidigare erfarenheter av VR ochspel. Studien bidrar med kunskap om vad som är viktigt för att handinteraktion skauppfattas som naturligt och realistiskt för att stödja immersion när det används i VR.Virtual reality (VR) is becoming more commonly used by people in areas like educationand entertainment. However, for VR to be a serious platform for creating education andentertainment services, the sense of immersion is an important part of the userexperience. Today there are several methods to interact with VR, but they often lack thefeeling of being natural and realistic. Hand interaction is seen as a natural way for peopleto interact with VR and has potential to create immersion. However, even though handinteraction is seen to be a natural way of interacting with VR there’s no guidelinesavailable to facilitate the design of VR-services with hand interaction. To study how handinteraction can be designed to support immersion in VR, we’ve asked the question:“How can hand interaction be designed for virtual reality to support immersion?”Through our study, we have identified aspects that are important for hand interaction tobe able to support immersion. The question has been studied through a design orientedapproach with qualitative data gathering methods such as participant test, interviews andobservations. The test participants were recruited based on their previous experience ofVR and games. The study contributes with knowledge regarding what is important for

This dissertation aims at researching concepts that emerged from virtual reality studies, through a non-dualistic approach. It starts with a survey about the main technical concepts of virtual reality immersion, presence, and engagement as considered by authors such as Heim, Biocca, Heeter, Grau, Lombard & Ditton. Meanwhile, it is outlined an argument which states that these concepts have emerged from design desires and goals. Afterwards, in order to seek an alternative to the dualism that underlies objectivist approaches of virtual reality, chapters two and three engage to the phenomenological understanding of the lived experience of the space. Therefore, it focuses on studying both Merleau-Ponty's phenomenology of perception and Bachelard's phenomenology of poetic imagination. By clashing this philosophy and those concepts previously considered, two issues have been considered: the body as being-in-the-world and the reverie as poetic activity of inhabiting. These two themes suggest the need to re-articulate the understanding of virtual reality-promoted definitions and applications. On chapter four, in addition to the phenomenological approach, it is discussed the issue of the imagination and participation in game's virtual environment, through the concepts of technical image and imagination from Flusser. Finally, it is suggested a possible way to understand immersion through the phenomenological concept of situation
Esta dissertação tem como meta principal de pesquisa o exame de conceitos da realidade virtual a partir de uma abordagem não-dualista. Começa por fazer um levantamento dos principais conceitos técnicos abrangidos por esse corpo de conhecimentos imersão, presença e engajamento através de autores como Heim, Biocca, Heeter, Grau, Lombard & Ditton. Esboça, enquanto isso, o argumento de que tais conceitos surgem como desejos e metas de design. Em seguida, a fim de buscar uma alternativa ao dualismo intrínseco às abordagens objetivistas da realidade virtual, os capítulos dois e três aplicam-se na compreensão fenomenológica da vivência do espaço. Para tanto, foca-se na leitura, primeiro, da fenomenologia da percepção de Merleau- Ponty e, depois, da fenomenologia da imaginação poética de Bachelard. No embate dessa filosofia com os conceitos anteriormente considerados, surgem os temas do corpo como ser-nomundo e do devaneio como atividade poética do habitar. Estes dois temas sugerem a rearticulação da compreensão das definições e aplicações práticas promovidas pela realidade virtual. No capítulo quatro, como complemento à abordagem fenomenológica, é discutido o problema da imaginação e da participação no ambiente virtual do jogo a partir dos conceitos de imagem e imaginação técnicas de Flusser. Finalmente, é sugerido um possível modo de se compreender a imersão a partir da concepção fenomenológica da situação

Abstract:
Si les possibilités de numérisation 3D de la présente réalité d'un site archéologique par le biais des dernières techniques d'acquisition 3D (photogrammétrie/scan laser) aident à la compréhension de son fonctionnement, elles peuvent aussi permettre de véritables hypothèses de reconstitutions de celui-ci tel qu'il a pu l'être à une époque donnée. Les besoins de la communauté archéologique concernant ces restitutions de structures ou d'environnements sont en effet considérables car, au-delà d'un intérêt évident en termes de valorisation du patrimoine, celles-ci permettent de véritablement mieux appréhender leurs fonctionnements et les sociétés qui les ont occupés. C'est partant de ce contexte que le premier objectif de cette thèse a été d'opérer, traiter et analyser différents niveaux de production d'environnements archéologiques 3D pour la recherche archéologique. Le second objectif a concerné la conception et la mise en place de méthodes d'interactions et de simulations immersives pour que les archéologues puissent démontrer certaines hypothèses, notamment en travaillant sur la perception d'indices visuels pertinentsThe possibilities of 3D digitisations of an archaeological site's current reality help to understand how it works, but they can also enable hypothesis about the reconstitutions of the site as it should have been in the past. Indeed the needs of archaeologists in the reproductions of those structures or environments are significant because, beyond an obvious advantage in terms of valuation of the heritage, they make it possible to understand better their organisation and the people that lived there. It is from this context that the first objective of this thesis was to operate, process and analyze different levels of 3D archaeological environments production for archaeological research. The second objective has concerned the design and implementation of immersive interaction and simulation methods so that archaeologists could demonstrate certain hypotheses, in particular by working on the perception of relevant visual cues
Se le possibilità di digitalizzazione 3D della situazione presente di un sito archeologico tramite le ultime tecniche di acquisizione 3D ( fotogrammetria, scan laser) aiutano alla comprensione del suo funzionamento, possono permettere anche delle veritiere ipotesi di ricostituzione di come esso potesse essere ad una determinata epoca. I bisogni della comunità archeologica riguardo a queste restituzioni di strutture o ambienti sono in effetti considerevoli poiché, al di là di un evidente interesse in termini di valorizzazione di patrimonio, permettono di comprendere al meglio i loro funzionamenti e le società che li hanno occupati. E' a partire da questo contesto, che il primo obbiettivo di questa tesi è stato quello di operare, trattare e analizzare diversi livelli di produzione di ambienti archeologici 3D per la ricerca archeologica. Il secondo obbiettivo riguarda la concezione e la realizzazione di metodi di interazione e di simulazione immersivi affinchè gli archeologi possano mostrare certe ipotesi, in particolar modo lavorando sulla percezione di indici visuali pertinenti
Se as possibilidades de digitalização 3D da realidade actual de um sítio arqueológico através das mais recentes técnicas de aquisição 3D (fotogrametria / laser scanning) ajudam à compreensão do funcionamento do mesmo, elas possibilitam, também, hipóteses de reconstituição do sítio tal como este seria no passado. As necessidades da comunidade arqueológica no que concerne a reproduções de estruturas ou de ambientes são, sem dúvida, consideráveis, uma vez que, para além do claro interesse em termos de valorização do património, estas permitem uma melhor apreensão dos seus funcionamentos e das sociedades que os ocuparam. Neste contexto, o primeiro objectivo da presente dissertação foi o de criar, processar e analisar diferentes níveis de produção de ambientes arqueológicos 3D destinados à investigação arqueológica. O segundo objectivo visou a concepção e a implementação de métodos de interacção e simulação imersivas para que os arqueólogos pudessem demonstrar determinadas hipóteses, em particular incidindo na percepção de índices visuais pertinentes

Si las posibilidades de digitalización 3D de la realidad presente de un sitio arqueológico a través de las últimas técnicas de adquisición 3D (fotogrametría / escaneo láser) ayudan a entender su funcionamiento, también permiten auténticas hipótesis de reconstrucción de éste tal y como pudo ser en cierta época. Las necesidades de la comunidad arqueológica cuanto a estas restituciones de estructuras o de entornos son de hecho considerables pues, además del interés evidente en términos de valorización del patrimonio, estas permiten de concebir realmente mejor tanto sus funciones como las sociedades que los han ocupado. Es partiendo de este contexto que el primer objetivo de esta tesis ha sido el de realizar, tratar y analizar diferentes niveles de producción de entornos arqueológicos 3D para la investigación arqueológica. El segundo objetivo ha abarcado la concepción y el establecimiento de métodos de interacciones y de simulaciones inmersivos para que los arqueólogos puedan demostrar ciertas hipótesis, especialmente trabajando sobre la percepción de indicios visuales pertinentes

In der Tat sind die Erkenntnisse der Archäologen bei der Reproduktion dieser Strukturen oder deren Umgebungen bedeutsam, da sie einen offensichtlichen Vorteil hinsichtlich der Bewertung und des Verständnisses über die Herkunft, die Organisation und die Menschen, die dort lebten, ermöglichen. Vor diesem Hintergrund war das erste Ziel dieser Arbeit, verschiedene Ebenen der 3D-Archäologie für die archäologische Forschung zu bearbeiten, zu prozessieren und anschließend zu analysieren. Das zweite Ziel dieser Arbeit befasste sich mit dem Entwurf und der Implementierung von Interaktions- und Simulationsmethoden. mit denen die Archäologen, dann bestimmte Hypothesen demonstrieren könnten. Insbesondere durch die Verarbeitung der Wahrnehmung von relevanten visuellen Hinweisen
Möjligheten att 3D-digitalisera ett arkeologiskt områdes nuvarande tillstånd underlättar förståelsen av området, och kan generera hypoteser kring hur området kan ha sett ut tidigare. Arkeologers behov av att återskapa strukturer och miljöer är betydande, eftersom det inte bara förenklar värderingen av fynden, utan för att det också gör det möjligt att bättre förstå hur miljön var organiserad och fösta människorna som levde där. Utifrån denna kontext är det första syftet med denna avhandling att styra, bearbeta och analysera olika nivåer av produktion av arkeologiska 3D-modeller för arkeologisk forskning. Det andra syftet rör design och implementering av immersiva interaktions- och simuleringsmetoder för att arkeologer ska kunna visa specifika hypoteser, särskilt genom varseblivning av relevanta visuella signaler

Sorbier, de Pougnadoresse François de. "Approches visuelles pour l'amélioration de la présence en réalité virtuelle." Thesis, Paris Est, 2008. http://www.theses.fr/2008PEST0205/document.
Abstract:
Le sentiment de présence, but ultime de la réalité virtuelle, peut être atteint en stimulant ces quatre "piliers" que sont l'immersion, l'interaction, le maintien de la boucle action-perception et les émotions. Notre objectif est de proposer des méthodes visant à améliorer ce sentiment en s'intéressant plus particulièrement à la perception visuelle. Dans cette optique, nous proposons tout d'abord une solution appliquant le rendu stéréoscopique sur carte graphique. Traditionnellement effectué en deux passes, ce rendu se fait maintenant en une passe, grâce aux shaders et au regroupement de certaines phases de calculs. Nous étendons ce processus de rendu aux tout récents écrans auto-stéréoscopiques nécessitant plus de deux vues, améliorant d'autant plus les temps de calcul. Pour assurer l'immersion et l'interaction, voire l'émotion, nous avons aussi cherché à diminuer la fatigue oculaire induite par les images stéréoscopiques, en ajoutant un flou de profondeur de champ. Ce flou, obtenu en temps réel grâce aux shaders, permet également d'inviter l'observateur à focaliser son attention sur des objets précis au lieu de laisser son regard errer. Enfin, un objectif pour obtenir le sentiment de présence est de faire croire à l'utilisateur qu'il existe dans la scène virtuelle. Notre contribution à ce but, est d'intégrer de manière naturelle une représentation virtuelle de l'utilisateur. Pour cela, nous créons par visual hulls un avatar à l'aide de caméras. Finalement, cet avatar est employé pour illustrer la présence de l'utilisateur au travers de surfaces réfléchissantes virtuelles ou de la projection de son ombreThe feeling of presence is the ultimate goal of a virtual reality system. It can be achieved by stimulating its four pillars that are immersion, interaction, consistency of the action-perception loop and emotions. Our objective is submit methods which could increase this feeling of presence. We will especially focus on visual perception. First, we present a solution applying the stereoscopic rendering on GPU. Using the latest shaders extensions, we join the traditional two passes to a single that reduce redundant computation. Our method can also be applied on recent autostereoscopic screens which need about ten different view points. The second contribution refers to eyestrain caused when a user watches stereoscopic images during a long time. We propose to use the graphic cards to render, in real time, a blur on problematic areas thus the user will focus on the others. We also use blur to point out some objects of the virtual scene that we considerate as important and avoid to let user's eye wander. Finally, we propose a method to increase the presence of the user into the virtual environment. An avatar, based on images taken from several cameras and visual hull method, is first build. In a second stage, the avatar is integrated into the virtual scene so it seems natural to the user. Thus we use reflective surfaces like mirrors or virtual lights interactions like shadows

Abstract:
Les développements récents de la réalité virtuelle font du travail collaboratif assisté par ordinateur un outil prometteur et flexible. Il est en effet aujourd’hui possible, de représenter les données ainsi que les utilisateurs eux-mêmes de manière vivante dans les environnements virtuels collaboratifs (EVC). Les EVC se définissent comme des mondes virtuels distribués, générés par ordinateur, dans lesquels les utilisateurs peuvent se rencontrer, communiquer et interagir entre eux, mais aussi avec des données et des objets 3D. Les utilisateurs peuvent être éloignés physiquement, parler des langues différentes et utiliser des systèmes informatiques hétérogènes tout en collaborant malgré tout au sein d’un EVC. L’objectif principal des EVC est de proposer une collaboration fluide entre plusieurs utilisateurs. Ceci implique de prendre en charge un nombre considérable d’échanges, de communications et de négociations mais également de permettre des activités collaboratives. Par ailleurs, il est nécessaire de proposer des techniques d’interaction ainsi que des moyens pour bien prendre conscience de tout ce qui se passe dans l’environnement. Afin de préserver ces différents aspects dans la conception des EVC, nous nous intéressons à quatre facteurs essentiels : l’immersion, la conscience, la communication et l’intuitivité. Ces facteurs sont déterminants pour le succès des systèmes virtuels collaboratifs. En tenant compte des quatre facteurs cités cidessus, nous proposons et évaluons de nouvelles métaphores pour la navigation et la manipulation afin d’améliorer et d’enrichir les techniques d’interactions dans les EVC. Premièrement, nous proposons et évaluons un ensemble de trois métaphores de navigation pour explorer un environnement à plusieurs : indiquer un chemin en dessinant des flèches, illuminer un chemin à suivre et orienter une boussole pour montrer une direction. Ces métaphores peuvent être implémentées dynamiquement et utilisées directement dans n’importe quels environnements. Nos résultats révèlent que ces métaphores de navigation réduisent considérablement le temps passé à chercher un chemin dans des contextes d’exploration collaborative. Par ailleurs, nous avons développé une technique de manipulation directe dédiée aux environnements virtuels immersifs. Cette technique, qui utilise sept points de contrôle, affranchit l’utilisateur de plusieurs difficultés souvent rencontrées telles que le tremblement de la main ou l’effet Heisenberg lors de la manipulation d’objets 3D dans un système de projection immersive. En réduisant le nombre de degrés de liberté de l’objet manipulé à l’aide de point de contrôle, notre technique permet à l’utilisateur de contrôler partiellement l’objet, rendant ainsi la manipulation d’objets volumineux plus aisée. Enfin, nous avons implémenté et évalué deux métaphores d'interaction dans une application de conception et d'aménagement de poste de travail industriel. En tenant compte des quatre facteurs cités ci-dessus, nous avons implémenté une application de conception de poste de travail pour trois principaux types d'utilisateurs : un utilisateur final, un ingénieur et un expert en ergonomie. Afin d'avoir un niveau d'immersion optimal et des interactions naturelles entre des utilisateurs, nous avons implémenté une configuration de système asymétrique pour chaque utilisateur. Chacun pouvait utiliser quelque métaphores de communication implicites qui étaient simples, naturelles, et pertinentes dans notre contexte collaborativeRecent progress of the virtual reality technology gives the computer supported collaborative work a potential and flexible tool of vividly representing data as well as users themselves in collaborative virtual environments. Collaborative virtual environments have been defined as computer-based, distributed virtual worlds in which people can meet, communicate and interact with others, with data and 3D objects. People may be geometrically far from each other, speak different languages and use heterogeneous computer systems. The ultimate goal in developing collaborative virtual environments is to support a smooth collaboration between multiple users which involves considerable communication and negotiation, cooperative and collaborative activities, interaction techniques, and awareness process. Considering these aspects into the design of a collaborative virtual environment, we are interested in four main factors, including immersion, awareness, communication and naturalness. These factors greatly determine the success of a collaborative virtual system. From the need of improving and completing interaction techniques in CVEs considering the four preceding factors, in this research we propose and evaluate new metaphors for 3D navigation and manipulation techniques. The first contribution of this research is to propose and evaluate a set of three navigation metaphors in a collaborative exploration context, including drawing directional arrows, lighting up path to follow, and orientating a compass to show a direction. These navigation metaphors can be dynamically implemented and used without constraints in any 3D virtual environments. The empirical result of our experiment revealed that these navigation metaphors considerably reduced wasted time in a wayfinding task of a collaborative exploring scenario. We have developed, in the second part of this research, a direct manipulation technique in immersive virtual environments. This manipulation technique deals with some difficulties the user often encounters such as hand jitter or Heisenberg effects while manipulating 3D objects in immersive projection systems. By dividing the number of degrees of freedom of the manipulated object into each handle of our tool, our technique enables a user to partially control the object, making the manipulation of large objects easier in immersive virtual environments. The last contribution of this research is the implementation and evaluation of two interaction metaphors in a digital mock-up application. Taking into account the four factors including immersion, awareness, communication and naturalness, we have built a workstation design application for three main users: an end-user, a design engineer and an ergonomics expert. In order to have an optimal immersion for the whole application and natural interaction between them, we have implemented an asymmetric system setup at each user's site. Each user could use some implicit communication metaphors which were simple, natural and still relevant in our collaborative context

Abstract:
Working with the public benefit corporation SURVIVR, I conducted a user experience study to determine how effective the Summer 2019 build of the virtual reality (VR) police training tool SurviVR was at meeting the product's goal of providing officers-in-training with realistic, immersive training experience. Two virtual training scenarios, entitled Active Shooter and Emotionally Disturbed Person (EDP), were the focal points of the study. At two of the product's pilot demonstration locations over eleven total sessions, I gathered observational data and audiovisual recordings and administered paper surveys based in qualitative methods (with a few quantitative elements). Using these data collection tools and techniques, I inquired into the themes of immersion and realism in the virtual scenarios and what design features the participants felt positively or negatively impacted their experiences of these themes. SurviVR's nature of containing both real-world and virtual elements that are pertinent to user experience necessitated a framework that addresses ethnography of virtual worlds, hybrid ethnography, and design anthropology. This study contributes to the expanding field of VR applications and understanding how improved immersion and realism can aid in the effectiveness of VR as a training tool.

Abstract:
Virtual Production is a relatively new concept that covers a broad selection of production approaches focused on combining physical and virtual content together in real-time. However, Virtual Production currently has perceptual limitations that impact on an actor's understanding of the virtual environment during a performance. This study explored various approaches to address this limited perceptual experience by minimising an actor's responsibility for the systems found in Virtual Production. The findings of the study led to the creation of a conceptual framework that can be used to facilitate an actor's perceptual experience of a virtual environment during a performance.

In this text we will travel through a critical exposition of the three-dimensional effects in movies and games development history creating a relation between the immersive factor and the technique of its production, we will seek to clarify how its developments, both aesthetic and technological, are reinventing the importance of image in contemporary society. Therefore, we will begin to show the context of production and levels of immersion, then move on to introduce an analytical look about the same. We will pass through the concepts of procedural modeling used in the industry of games, and the preference on its use on implementing the creation for vegetation landscapes. Then we elucidate these points through the game analysis The Witcher III, especially the landscape and vegetation through a match with the real tree that meet the aesthetic characteristics of the chosen object in the game
Neste texto iremos proceder a uma exposição crítica da história do desenvolvimento dos efeitos tridimensionais no cinema e nos jogos tecendo uma relação entre o fator imersivo com a técnica utilizada para a produção deste, ao mesmo tempo, vamos procurar elucidar de que forma seu desenvolvimento, tanto estético quanto tecnológico, vem reinventando a importância da imagem na sociedade contemporânea. Para tanto, começaremos por mostrar o contexto de produção e níveis de imersão, passando em seguida a introduzir um olhar analítico sobre o mesmo. Logo após, abordaremos conceitos empregados em modelagem procedural na indústria de jogos, suas vantagens e desvantagens, e sobre sua utilização para implementação na criação de paisagens vegetais. Em seguida, exemplificaremos esses pontos através da análise do game The Witcher III, em especial a paisagem e a vegetação, através de uma equiparação com a árvore real que atendam as características estéticas do objeto escolhido no jogo

Thesis, KTH, Skolan för elektroteknik och datavetenskap (EECS), 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-280851.
Abstract:
Motion capture systems are becoming more common within the entertainment industry, used for capturing actor’s movements and performances for animation purposes. However, the empty setting in which these performances take place differ a lot from traditional acting scenarios usually comprised of de- tailed sets, costumes and props. The main challenges actors face is the mental work required to visualize an environment or characters that is not physically there. Furthermore, without proper reference it is difficult to find the right natural movements for one’s differently proportioned character, as well as acting towards such a character. By constructing a system utilizing virtual reality (VR) headsets in combination with motion capture technology, the goal was to bring both the environments and characters into the live performance. The evaluation was conducted by comparing when a pair of users performed a scene in both the traditional motion capture setup and the VR setup. It was decided to measure their overall sense of embodiment as many of the underlying elements align with immersive qualities. This includes measuring their sense of presence, agency, and their connection to their character but also their acting partner’s character. Qualitative data was gathered through post-performance interviews and a questionnaire where participants rated different statements related to the sense of embodiment using a 5-point Likert scale. The final results implies that the VR system improves some aspects associated with embodiment in comparison to the traditional setup. This in turn changed the way the participants performed the scenes. The majority stated that they had an easier time of portraying their characters when in VR. From the interviews conducted it seemed that the participants had an easier time playing towards the environment, as well as towards their acting partner, due to them being able to play off and react to things they could actually observe.Motion Capture-system har under den senaste tiden växt i popularitet, speciellt inom underhållningsbranschen. Med dessa system är det möjligt att spela in en skådespelares rörelser och sedan använda informationen för att animera 3D-figurer. Detta resulterar oftast i mer naturliga och verklighetstrogna animationer. Området där dessa uppträdanden äger rum skiljer sig dock markant från de mer traditionella scenarion som skådespelare oftast finner sig i. Istället för att ta användning av rekvisita, kostymer och detaljerade scener utspelar sig det mesta i relativt tomma lokaler. Detta medför vissa utmaningar, främst den stora mentala bördan av att konstant behöva visualisera miljö och karaktärer som fysiskt inte finns på plats. Svårigheter uppkommer även när skådespelare måste arbeta fram rätt rörelser samt referenspunkter, då de kan tvingas spela med karaktärer som skiljer sig i storlek och proportion från de verkliga skådespelarna. Genom att konstruera ett verktyg som utnyttjar både Virtual Reality (VR) och Motion Capture-teknologi är målet att transportera skådespelarna till av- sedd miljö, där de kan uppleva alla interaktioner utifrån sina karaktärers perspektiv. Utvärderingen utfördes genom att låta två skådespelare tillsammans spela upp samma scen i både traditionell Motion Capture såväl som i det nya VR-upplägget. Det var bestämt att mäta olika delar av deltagarnas virtuella för- kroppsligande eftersom många av dessa aspekter överlappar med det önskade resultatet av att förbättra skådespelarens immersion. Kvalitativ data samlades genom att intervjua deltagarna efter varje uppträdande, de fick även fylla i ett frågeformulär där de betygsatte diverse påståenden kopplade till virtuellt för- kroppsligande med hjälp av en 5-poängs Likertskala. De slutgiltiga resultaten indikerar att VR-verktyget, i jämförelse med det traditionella systemet, förbättrade vissa aspekter associerade med virtuellt förkroppsligande. Detta ledde till förändringar i hur deltagarna uppträdde, då majoriteten av dem konstaterade att de fann det lättare att porträttera sina karaktärer i den virtuella miljön. Ut- ifrån intervjuerna kan det även konstateras att deltagarna fann det lättare att skådespela i relation till den virtuella miljön, så väl som sin motspelares karaktär, eftersom det nu fanns visuella referenser att förhålla sig till.

Abstract:
As a cutting-edge technology, VR is applied to all aspects of life. Especially when the pandemic is spreading, the immersive experience of VR provides another possibility for people's virtual tours and online exhibitions. Limited by the high price of professional VR equipment, VR technology still exists in specific professional fields. This project mainly studies some of the challenges of immersive experience on mobile phones and improves the immersive experience to make the virtual tour convenient and straightforward on mobile phones. Through research, it is found that interactive 360-video may be a potential solution. Users can explore freely in 360-video and interact with people or things in the environment. The most important thing is that interactive 360-video can rely on mobile phones as a medium so that everyone can afford it, and it allows users to explore and discover anytime, anywhere.Examensarbetet är utfört vid Institutionen för teknik och naturvetenskap (ITN) vid Tekniska fakulteten, Linköpings universitet

Abstract:
Over the past few years, video games have served as a catalyst for virtual reality (VR) technology to become more accessible to the average consumer, resulting in an increased interest in VR’s potential applications across several disciplines. To best capitalize on these applications, however, researchers require a thorough understanding of the user’s experience in virtual environments. And while many studies on VR experiences tend to focus on presence, video games offer another angle of approach: immersion. This study uses both qualitative and quantitative methods to examine the relationships between the VR experience of presence and the gaming experience of immersion. First, a focus group of individuals with VR gaming experience explored variables impacting presence. Then a survey questionnaire consisting of items from the multimodal presence scale (MPS), Jennett et al.’s (2008) immersion questionnaire, and the focus group was distributed online. Finally, the collected data was analyzed using factor analysis and linear regression to explore the relationships between presence and immersion. Results of the analysis identified involvement to be an important factor impacting a user’s perceived presence in a VR gaming experience.

Abstract:
In recent years, the edges between reality and virtual reality have been further smudged as today’s software and hardware allows for wireless immersive experiences. In an attempt to solve locomotion as the last piece of the puzzle of perfecting immersive virtual realities, impossible spaces have been developed to support natural locomotion. This in-between subject study investigated the effects of the combination of climbing and free walking on immersion in an impossible space environment with 20 participants. Users tended to greatly underestimate the distance climbed (which contradicts a previous study), concentrate, lose track of time, describe their experience more positively and differently than the controls group. Signs of spatial, emotional, cognitive and tactical immersion were shown in aspects of concentration, time, feelings of freedom, narrative, presence, safety, mental stimulation and locomotion user strategies to name a few. Minimal cues may have been present while future studies might fully confirm and define the immersive potential of vertical locomotion in impossible spaces.De senaste årens utveckling har fortsatt sudda ut kanterna mellan verklighet och virtuell verklighet då dagens teknik stödjer trådlösa immersiva verkligheter. I ett försök att lösa locomotion som det sista biten av pusslet för att göra virtuella verkligheter perfekta har s.k impossible spaces utvecklats för att stödja naturlig locomotion. Den här A/B-gruppsstudien undersökte effekter på immersion med kombinationen av naturlig och vertikal locomotion i en impossibel space miljö med 20 deltagare. Användare tenderade att grovt underskatta längden de klättrade (vilket motsäger en tidigare studie), koncentrera sig, tappa tidsuppfattningen, beskriva deras upplevelsen mer positivt och annorlunda än kontrollgruppen. Tecken på rumslig, emotionell, kognitiv och taktil immersion visade sig i form av koncentration, tid, känslor av frihet, narrativ, närvaro, säkerhet, mental stimulation och locomotion- användarstrategier för att nämna några. Minimala element kan ha uppnåtts medan framtida studies kan bekräfta och definiera den immersiva potentialen med vertikal locomotion i impossibel spaces till fullo.

Abstract:
Les simulateurs de conduite permettent d’étudier le comportement humain dans différentes conditions fixées expérimentalement. Un avantage majeur de la simulation est de ne pas exposer le sujet à un risque objectif et que les conditions de test sont "facilement" mises en œuvre et manipulées. Le recours à la simulation pose néanmoins la question de la généralisation et transposition des comportements observés en simulation à la situation réelle de conduite. En effet, il est nécessaire de s’assurer que le simulateur mesure précisément l’objet d’étude sans le modifier ou l’influencer. L’évaluation du degré de validité est donc cruciale dans toute étude sur simulateur qui cherche à susciter des comportements réalistes de conducteurs. Le postulat de notre travail repose donc sur l’idée que la présence est un concept clé pour évaluer la représentativité des comportements de conduite observés en simulation. Toutefois plusieurs difficultés seront à résoudre. Une des plus cruciales repose sur le fait que la présence est difficilement mesurable en temps réel puisque le fait même de chercher à la mesurer peut rompre l’état de présence plus ou moins existant. Ainsi obtenir des indicateurs comportementaux de la présence constitue un véritable enjeu pour caractériser la nature d’un phénomène qui à l’heure actuelle est davantage fantasmé à l’aide de mesures post-expérimentation que concrètement démontré par la mise en évidence de comportements spécifiques reproductiblesDriving simulators make it possible to study human behavior in different experimentally determined conditions. A major benefit of simulation is that it does not expose the subject to an objective risk and that test conditions are "easily" implemented and manipulated. The use of simulation nevertheless raises the question of the generalization and transposition of the behaviors observed in simulation to the actual driving situation. Indeed, it is necessary to ensure that the simulator accurately measures the object of study without modifying or influencing it. Assessing the degree of validity is therefore crucial in any simulator study that seeks to create realistic driver behaviors. The postulate of our work is therefore based on the idea that presence is a key concept for assessing the representativeness of driving behaviors observed in simulation. However, several difficulties will have to be solved. One of the most crucial is the fact that presence is difficult to measure in real time because the very fact of trying to measure it can break the more or less existing presence state. Thus, to obtain behavioral indicators of presence is a real challenge to characterize the nature of a phenomenon which at present is more fantasized by post-experimental measures than concretely demonstrated by the demonstration of specific reproducible behaviors

The impact of virtual reality technologies as well as the influence of gaming narratives have favored what we call immersive rhetoric, a storytelling form based on visual and interactive resources which aim to achieve a high degree of user immersion. Immersive journalism we understand as an emerging journalistic practice that applies the technologies and resources needed to achieve that goal. While immersive journalism has its greatest expression in the application of immersive virtual reality technology, immersive tecniques can also be applied through the digital display. We first propose the expressive components for immersive journalism based on the visual interface and then we analize their journalistic applications.

Abstract:
Technologies in digital cinema are quickly changing the way contemporary filmmakers create films and how audiences currently perceive them. As we move onward into the digital turn, it becomes ever more apparent that the medium of film has been emancipated from its dependence on the photograph. Directors are no longer required to capture the objectively real as it sits before the photographic lens, but can essentially construct it via groundbreaking advancements in computer-generated imagery, motion capture technology, and digital 3D camera systems and display technologies. Since the origins of film, spectators and filmmakers have assumed an existing relationship between reality and the photographic image. Yet digital film technologies now provide us with hyper-facsimiles of reality that are perceived as photographic, but are often created by way of computer processes. Digital cinema currently allows the viewer to inhabit and interact with cinematic realities in unprecedented ways, and it is this contemporary paradigmatic shift from the analog to the digital that has catalyzed fundamentally new ways of looking at the filmic image. In this paper, I will examine the perceptual complexities of contemporary digital film through the lens of these cinematic technologies by examining their impact on the viewer’s experience.

Abstract:
Dans un contexte industriel en constante évolution, le designer industriel utilise la représentation comme un vecteur lui permettant de s’inspirer et d’opérer des choix stylistiques afin d’imaginer l’expérience induite par les concepts de produits qu’il développe. Ce travail doctoral présente l'étude comparative entre l'activité de design amont traditionnelle et l'activité de design amont immersive, permettant l'évaluation et la modélisation de l'activité de Kansei Design Virtuel. Mes travaux portent essentiellement sur l'application et l'expérimentation de théories fondamentales à travers la conception de deux outils consécutifs du processus de design:• Les Univers de Tendance sont des environnements inspirationnels spatiaux immersifs dédies à la compréhension d'une tendance stylistique et conçu pour substituer et augmenter le rôle des planches de tendances traditionnelles.• Le Dessin Tridimensionnel Immersif est un environnement générationnel permettant au designer de déposer, effacer, manipuler… un tracé dans l'espace et dédié aux premiers croquis d'idéation.Ces recherches ont pour but de développer des outils et un workflow digital immersif permettant d'une part, d'anticiper le Kansei (relation holistique designer/client-produit) afin d'optimiser les choix stylistiques stratégiques et d'autre part, de maximiser la fidélité de retranscription entre espace d'inspiration et espace de génération tout en augmentant la capacité du designer à produire des concepts esthétiques et innovantsIn an ever-changing context, the industrial design uses representation as a vector for inspiration and as a tool to operate stylistic choices which in turn enable the shaping of the experience induced by the designed product.This doctoral research presents the comparative study of traditional early design activity and immersive early design activity. This enables the evaluation and modeling of Virtual Kansei Design. My work essentially address the application and experimentation of fundamental theories through the design of two successive tools composing and innovative early design process.• The Immersive Moodboards are spatial immersive inspirational environments dedicated to the understanding of a stylistic trend, designed to substitute and enhance traditional moodboards.• The Immersive sketching is a generational environment enabling the design to position, erase, manipulate… a graphical mark in a three dimensional space planned for the creation of the first ideation sketches.This research aim to develop tools and a digital immersive workflow which first of all enables the design to anticipate Kansei (holistic relationship between the designer/user and the product) in order to optimize strategic style related choices and secondly enhances the fidelity between inspiration and generation while increasing the ability of the designer to produce innovating and aesthetic concepts
