Articles de revues sur le sujet « Casque immersif »

Les technologies immersives ont fait leur apparition dans bon nombre d’outils de modélisation architecturale. Néanmoins, leur usage se limite bien souvent à des fins de visualisation, par exemple pour valider un design auprès d’un client muni d’un casque de réalité virtuelle. Notre travail vise à permettre une utilisation de ce medium immersif durant l’activité de conception architecturale elle-même. Nous présentons dès lors un outil de modélisation paramétrique en réalité virtuelle permettant de combiner, en immersion, l’édition de modèles Grasshopper et la visualisation des géométries générées. Nous validerons notre approche auprès d’architectes et d’étudiants formés à ce paradigme de conception.

Nous présentons un système de réalité virtuelle qui a été mis en place afin de permettre à tous de visiter virtuellement les nouvelles salles blanches de l’ESIEE. C’est une visite immersive qui peut s’effectuer à l’aide d’un casque de réalité virtuelle ou bien dans une salle spécifique de projection que nous décrivons. Ce parcours virtuel permet de se déplacer dans toutes les pièces du bâtiment ainsi que de visiter les locaux techniques. Il offre le choix d’afficher des images de synthèse ou bien des photos panoramiques. Nous décrivons ici les outils utilisés ainsi que toutes les étapes qui ont mené à la réalisation de cette application.

Au cours de cet exposé nous présenterons nos activités de recherche dans plusieurs domaines. Nous commencerons par le domaine de la réalité virtuelle qui correspond à l’interaction avec des univers 3D simulés et restitués en temps réel par des ordinateurs. La réalité virtuelle permet d’envisager des applications nombreuses en médecine tels que les simulateurs chirurgicaux pour s’entraîner sur des patients virtuels ou bien, en psychiatrie, des simulateurs immersifs permettant de traiter des phobies par exposition parfaitement contrôlée des patients. Nous évoquerons ensuite le domaine des interfaces cerveau-ordinateur qui permet d’extraire et d’analyser en temps réel l’activité cérébrale d’un utilisateur équipé d’un casque EEG (électro-encéphalo-graphie) pour pouvoir par exemple piloter des prothèses ou des fauteuils roulants sans activité motrice et uniquement « par la pensée ». Ces technologies peuvent être combinées et viser des applications de Neurofeedback. Ainsi au cours d’un projet récent nous avons participé à l’élaboration d’un simulateur de classe virtuelle dans laquelle des enfants souffrant de troubles attentionnels (ADHD) peuvent être immergés virtuellement et progressivement travailler leurs rythmes cérébraux liés à l’attention et à leur pathologie.

Les technologies immersives sont de plus en plus présentes dans le contexte éducatif. Même si certaines méta-analyses ont montré un résultat positif de certaines technologies immersives TI (Chen et al., 2020; Coban et al. 2022), nous devons encore explorer ses applications pratiques dans les classes. Les avantages pédagogiques ont été mentionnés à plusieurs reprises (Freina et Ott, 2015, Di Natale et al., 2020), mais ils peuvent être modérés par de nombreux défis dans la salle de classe. Dans cet article, nous avons proposé de faire la lumière sur deux études de cas d’exploitation pédagogique de la technologie immersive à l’aide de casques au niveau secondaire en univers social. Les expériences ont été documentées par des groupes de discussion avec les élèves et des entretiens individuels avec les enseignants. Le premier cas proposait d'explorer le conflit en Syrie sous différents angles, avec l'aide de vidéos à 360° et d’une application de visualisation de lieux dans le monde. Le second cas visait à amener les élèves à comparer la réalité passée et présente dans le contexte de Pékin, à partir de vidéos à 360° en réalité virtuelle. Les résultats ont montré que les TI ont un certain potentiel, mais que de nombreuses conditions doivent être mises en place pour en arriver à un usage pédagogique efficace.

El sentido de autoeficacia del profesorado en formación (PSTs) se estudia cada vez más por su impacto en el desarrollo profesional. Métodos como la microenseñanza han demostrado mejorar la autoeficacia del PSTs. Este estudio examina el impacto de la microenseñanza, grabada con cámaras de realidad virtual inmersiva (iVR), en la autoeficacia del PSTs. Se exploran los niveles de autoeficacia de los PSTs antes y después de la microenseñanza y sus percepciones posteriores. Utilizando un enfoque de método mixto, realizamos un diseño cuasi-experimental de pretest-postest con la Escala de Autoeficacia del Profesor (TSES) y grupos focales. El estudio involucró a 27 PSTs de inglés de un programa de máster en la Universidad de Las Palmas de Gran Canaria. El análisis cuantitativo mostró alta fiabilidad en las tres dimensiones de la TSES: estrategias de instrucción, gestión del aula y compromiso de los estudiantes, con mejoras significativas postest con respecto a las estrategias de enseñanza. El análisis cualitativo destacó la importancia de estas dimensiones junto con el uso innovador de iVR. Nuestros hallazgos sugieren que comprender las interacciones que afectan la autoeficacia puede mejorar el diseño de programas de formación docente, promover el crecimiento profesional y la confianza de los futuros educadores.

Within the framework of the new digital paradigm, a multitude of media have emerged that express communicational realities different from those institutionalised by conventional media groups. In Spain, alternative media proliferated after the crisis of 2008 and the transformation of the journalistic context, which is immersed in the digital economy. This work focuses on analysing La Poderío as a peripheral publication project with a gender perspective in the Spanish sphere, looking in depth at its trajectory and organisational structure, the strategies and communication channels it uses and its digital audience. It is a case study that has used in-depth interviews, web traffic analysis and the monitoring of metrics in social networks as tools. The results indicate that this is a project of non-mainstream journalistic cultural production with a gender perspective that values communication from the periphery and gives a voice to under-represented groups, helping to make alternative contexts of social and communicative interaction visible. However, with the intention of making proposals, elements have been detected that can facilitate its expansion and professionalization.

The three research questions are: (1) What are the formation and changes in the career constructs of people with adventitious blindness? (2) How do external factors affect the career development of people with adventitious blindness? (3) What are the career development process and career motivation changes in people with adventitious blindness? </p> <p> Methods </p> <p> The study adopted a purposive sampling and multiple case study approach and invited five participants with adventitious blindness for this study. Three of the five participants were male, and two were female, with an average age of 43. They had different occupations (e.g., massage, education care assistance, computer skill teaching, agriculture, computer information processing) and other causes of impairment (e.g., visual impairment due to chronic visible diseases, acute illness). Data were collected through in-depth semi-structured interviews, and data were analyzed using thematic analysis and triangulation techniques to ensure the reliability of the study to validate the findings. </p> <p> Results </p> <p> The findings of this study revealed that: (1) The process of forming and changing the career constructs of people with adventitious blindness is related to the pre-impairment successes (personal preferences, strengths, academic learning, and work outcomes), the influence of significant others (beliefs conveyed by significant others or primary supporters), career roles (the male participants have traditional male family roles, while the female participants tend to solve problems on their own and break away from the part of dependents) and values (obtaining a fair salary, establishing social relationships, and realizing self-actualization), and the construction of personal traits (feedback and reactions from others, and personal internal reflection). The key is to find one&rsquo;s value. Through constructing and reconstructing, they expand their diversified perspectives, develop more different resources, turn the impact of deteriorating vision into motivation to start anew, and have the courage to try to use new resources, find unexplored potential in the past, or open up new job opportunities. (2) The results of the study showed that external factors include: access to job opportunities (opportunities from social resources, referrals from schools or associations, family resources, personal expertise), changes in the general social environment, workplace environment, and working conditions (computerized work tasks and a lot of screen manipulation are very burdensome for people with adventitious blindness, and the content and duties of the jobs may exhaust the remaining vision and force them to change jobs) and job accommodation (adjusting work methods, using required assistive technology aids, natural supporters, professional assistance). All of these factors will affect the career development of the participants. In addition, when facing job challenges, participants will not only use different strategies but also make appropriate career choices by considering their current real-life needs and their impairment status. (3) For people with adventitious blindness, positive resilience (self-acceptance, resource application, overcoming external resistance) is the driving force that lays the foundation for their early career development. This resilience facilitates personal career insight (re-awareness of self, career preferences, and actual needs, job adjustment), career identity (application of professional skills, job roles, and performance), and career decisions and actions (initial job decisions, maintaining a current job, career transitions) for people with adventitious blindness. As their vision deteriorates and they face career change and adjustment, their positive resilience increases their motivation to make emotional adjustments and responses (e.g., actively seeking peer support, developing interests and sharing, family members&rsquo; companionship and support) and seeking diversified social resources (e.g., applying for disability identification, guide dog service, accommodated bus service, sighted guide runners services) to facilitate continuous career change and improvement. The second deterioration of vision is the main cut-off point for a career change, which again motivates them to change their career. </p> <p> Conclusions </p> <p> The suggestions of this study can be divided into two parts; one is for people with adventitious blindness: (1) People with adventitious blindness can take the initiative to learn about different resources and develop their ability to use and search for resources before their physiological functions change, and to seek help from others promptly. (2) People with adventitious blindness can build their interpersonal support network and avoid prolonged immersion in negative emotions. (3) In the face of social changes, they can use different social resources to improve their workability or make work adjustments, such as: building more life skills, strengthening orientation and mobility, and upgrading work equipment and systems to follow the social trend to enhance the opportunity to obtain work. (4) Being aware of one&rsquo;s values and sense of mission can help people with adventitious blindness to make appropriate career decisions. The second part is to provide an employment service model for people with adventitious blindness: (1) Employment services need to assess and individualize the service model or adjust the services according to the stage of career development, the degree of visual impairment, individual internal psychological state and external environment of people with adventitious blindness. If changes in their physical and mental functions are found, relevant units should actively intervene and assist them to reapply for services. (2) Employment service providers should consider the differences in the gender and career roles of people with adventitious blindness and the changes in their roles at different vision statuses to provide employment counseling strategies or support resources that meet their needs. Limitations and suggestions: This study has limitations: (1) Each participant&rsquo;s condition and environment differed. Hence, the results of this study must be interpreted with the specific background of each individual with impairment. However, future research can use the findings in this study as a reference when first encountering people with adventitious blindness. (2) The participants in this study mainly worked in metropolitan areas. The researchers did not get a chance to explore the experiences of career motivation changes of people with acquired blindness living in other non-metropolitan areas. Therefore, future researchers can identify the extent of the direct effects of various factors that impact the career construction and career development process or focus on exploring career reconstruction patterns in people with adventitious blindness. </p> <p> </p>

Métaverse, cette « vérité » communément admise devient encore plus évidente face à l’émergence des structures et mondes parallèles au sein de ces univers virtuels. Cependant, cet avenir très proche marqué par ces métaverses nous préoccupe, et rien ne semble pouvoir les empêcher de devenir une réalité. En effet, ces nouveaux territoires intangibles pourraient changer fondamentalement notre façon d’être et d’exister nous menant à questionner particulièrement leur impact sur nos processus cognitifs et affectifs ainsi que le rapport que nous entretenons les uns avec les autres. Cela nous mène en tant que chercheure designer de passer d’une posture théorique et spéculative à une posture plus active et participative afin d’explorer et de comprendre empiriquement cet impact dans le cadre d’une première étude exploratoire se basant sur un croisement entre le design et les neurosciences. Dans le cadre d’une expérimentation de l’expérimentation et afin d’explorer l’activité cérébrale des utilisateurs, ce travail présente une méthode de mesure neurophysiologique en utilisant le casque emotiv.

Les dispositifs artistiques de réalité virtuelle bousculent nos modes perceptifs tout en remettant en jeu notre corporéité et notre sensorialité via une immersion interactive multimodale propre à produire des « effets de présence » inédits. Nous proposons dans cet article d’interroger la place du corps du spectateur dans ces dispositifs afin de mettre au jour certains enjeux esthésiques des formes particulières qui s’y déploient. Nous montrerons notamment comment les nouvelles postures spectatorielles déterminées par ces derniers (via les notions de corps casqué et écran incorporé) contribuent à inscrire le spectateur dans un processus de corporéité performative.

Abstract Mordechai Narkiss (1897–1957), the first and long-serving curator of the Bezalel Museum in Jerusalem, was a pioneering scholar in Jewish art history. His significant contributions to the field are epitomized by his insightful critiques, written in Hebrew, of the leading scholars in his era. Narkiss’s rigorous reviews, reinforced by his deep immersion in Jewish tradition and extensive knowledge of the visual arts across various cultures, adeptly identified errors, unfounded assumptions, and methodological shortcomings. He underscored the importance of a solid foundation in both Judaism and art history. This article explores six of Narkiss’s critical reviews of seminal works in the field: Karl Schwarz, Die Juden in der Kunst (1928), Cecil Roth, The Casale Pilgrim (1929), Ernst Cohn-Wiener, Die jüdische Kunst (1929), Rachel Wischnitzer, Symbole und Gestalten der Jüdischen Kunst (1935), Franz Landsberger, Einführung in die Jüdische Kunst (1935), and Jacob Pinkerfeld, Synagogues of Italy (1954). It elucidates the complexities and debates within Jewish art historiography, highlighting Narkiss’s pivotal role in both critiquing and shaping scholarly discourse and emphasizing the ongoing relevance of meticulous research in Jewish art history.

При численном решении задач газовой динамики часто приходится сталкиваться с трудностями при обработке областей со сложной геометрией. Создание согласованных расчетных сеток для таких областей может быть крайне трудозатратной задачей. Применение метода погруженной границы помогает избежать данных проблем. Использование этого метода делает возможным проведение расчетов для тел со сложной геометрией даже с применением структурированных декартовых сеток. В данной статье рассматривается подход к реализации метода погруженной границы с использованием фиктивных ячеек, то есть таких ячеек, в которых требуется вычисление газодинамических величин только для того, чтобы провести расчеты для соседних ячеек сетки. Обычно данные фиктивные ячейки не относятся к расчетной области, они могут находиться полностью или практически полностью внутри обтекаемого тела. Расчет газодинамических параметров для фиктивных ячеек в трехмерном случае выполняется с помощью аппроксимации с использованием данных близлежащих ячеек расчетной области, а также с учетом приближения граничных условий. В данной статье при расчете обтекания тела рассматривается граничное условие Неймана. В статье приведены формулы для расчета скалярных и векторных газодинамических характеристик фиктивной ячейки на базе трех точек в пространстве с известными характеристиками и одной точки поверхности обтекаемого тела, в которой выполняется аппроксимация граничного условия. Описанный подход верифицировался в трехмерном случае, в котором расчетная область представлена прямоугольной равномерной декартовой сеткой, а обтекаемое тело описывается неструктурированной поверхностной сеткой, ячейки которой являются треугольниками. When solving numerically gas dynamics problems, one often encounters difficulties in processing regions with complex geometry. Generating consistent computational grids for such areas may be a complex task. The immersed boundary method avoids these problems. The use of this method makes it possible to carry out calculations for bodies with complex geometry, even using structured Cartesian grids. This article discusses an approach to the implementation of the immersed boundary method using ghost cells, that is, those cells in which the calculation of gas-dynamic quantities is required only in order to carry out calculations for neighboring grid cells. Usually these ghost cells do not belong to the computational domain; they can be located completely or almost completely inside the streamlined object. The calculation of gas-dynamic parameters for ghost cells in the three-dimensional case is performed using approximation using data from nearby cells of the computational grid, as well as taking into account the approximation of the boundary conditions. In this article, when calculating the flow around a body, the Neumann boundary condition is considered. The article presents formulas for calculating the scalar and vector gas-dynamic characteristics of a ghost cell based on three points in space with known characteristics and one point on the surface of the streamlined object, at which the boundary condition is approximated. The described approach was verified in the three-dimensional case, in which the computational domain is represented by a rectangular uniform Cartesian grid, and the streamlined object is described by an unstructured surface grid, the cells of which are triangles.

A 64 years old female was admitted to hospital due to having repeated blister on skin. Her Dsg1, Dsg3, Bp180, Bp230, VII collagen antibodies were all negative while her ENA-SSA and anti-CCP were positive. Labial glands biopsy revealed that lymphocytes immersed around the glands and a diagnose of Sjögren’s syndrome (SS) was made. Skin biopsy indicated subcorneal pustular with neutrophils immersed and direct immune fluorescence as well as blood and blister fluid culture were negative. Additionally, the patient showed a high expression of IL-6 (18371.09pg/mL) in peripheral blood and blister fluid (19997.89pg/mL).

This manual offers law teachers a comprehensive guide to implementing the case method effectively in their classrooms, allowing them to select appropriate cases, guide students in their analysis, encourage class participation, and comprehensively assess learning.

Virtual tours serve as powerful tools for education, preservation, and accessibility, especially within cultural heritage. This study develops a web application that utilises 360-panoramic views to elevate user experience in tourism promotion. Current digital tools for cultural sites often rely on static text and images, limiting the depth of user interaction. By integrating 360-panoramic technology, this project addresses these limitations, offering a more immersive and engaging experience. Focusing on the Wat Phou monument in Laos, the study utilises the open-source WebVR PannellumJS framework and advanced equipment, such as 360-degree cameras and UAVs, to create a lifelike and interactive exploration of the site. Panoramic images are linked to simulate a tour route, and traditional "hotspot" nodes guide users through a virtual experience with navigation options and full-screen viewing for orientation support. This research underscores the potential of VR360 technology in enhancing tourism promotion and heritage digitisation, ultimately fostering visitor engagement and contributing to socio-economic development through innovative cultural experiences.

Using Prince Kung’s Mansion as a case study, this paper examines the significance of national traditional culture in the advancement of tourism, as well as its corresponding modes and effectiveness. Through interviews, surveys, and on-site visits, the authors discovered that Prince Kung’s Mansion effectively merged traditional culture with tourism by utilizing digital technology to bring historical scenes to life, creating immersive cultural experiences, introducing a range of cultural and creative products, and establishing a comprehensive research and travel system. This study analyzes the successful practices of Prince Kung’s Mansion and suggests several strategies, including establishing a cultural gene database for a deeper exploration of cultural significance, utilizing technological innovations to enhance interactive experiences, implementing a dual-wheel drive system combining culture and services, establishing a broad communication network, and enhancing the evaluation mechanism for cultural and tourism integration. The findings of this research can serve as a valuable reference for the development of tourism at other cultural heritage sites, particularly in terms of balancing commercial growth and the preservation of cultural authenticity, and creating a shared cultural space for both hosts and visitors.

This documentary investigation exposes mistreatment and exploitation of Ugandan contractors injured while supporting U.S. military operations in Iraq and Afghanistan. Under the Defense Base Act (DBA), these workers were entitled to medical benefits and disability compensation if wounded overseas. However, complex bureaucracies and bias against foreign claimants led to systemic denial of their rights. Through legal document analysis, interviews with claimants and experts, and an immersive case study, consistent evidence emerges of local agents extorting funds, opaque processes delaying awards, discriminatory compensation compared to Western contractors, and lack of recourse. The Ugandan government failed to exercise oversight or advocate for citizens entangled in this biased system, allowing rampant abuse and theft by local agents. Thousands of Ugandan families were left devastated, sacrificed in service of American wars abroad without their own government's protection. This study gives voice to an invisible population robbed of dignity and justice after being injured in America's War on Terror. It compels radical reforms guided by empathy to uphold the moral promises owed to marginalized workers endangered in foreign battlefields. This documentary will raise awareness through poignant storytelling and irrefutable facts, engaging both hearts and minds to transform a broken system into one centered on human rights and redemption.
