Dissertations / Theses on the topic 'Intuitive user interface'

This thesis examines the role of intuition in the way that people operate unfamiliar devices, and the importance of this for designers. Intuition is a type of cognitive processing that is often　non-conscious and utilises stored experiential knowledge. Intuitive interaction involves the use of knowledge gained from other products and/or experiences. Therefore, products that people use intuitively are those with features they have encountered before. This position has been supported by two initial experimental studies, which revealed that prior exposure to products employing similar features helped participants to complete set tasks more quickly and intuitively, and that familiar　features were intuitively used more often than unfamiliar ones. Participants who had a higher level of familiarity with similar technologies were able to use significantly more of the　features intuitively the first time they　encountered them, and were significantly quicker at doing the tasks. Those who were less familiar with relevant technologies required more　assistance. A third experiment was designed to test four different interface designs on a remote control in order to establish which of two variables - a feature's appearance or its location - was more important in making a design intuitive to use. As with the previous experiments, the findings of Experiment 3 suggested that performance is　affected by a person's level of familiarity with similar technologies. Appearance (shape, size and labelling of buttons) seems to be the variable that most affects time spent on a task and intuitive uses. This suggests that the cues that people store in memory about a product's features depend on how the features look, rather than where on the product they are placed. Three principles of intuitive interaction have been developed. A conceptual tool has also been devised to guide designers in their planning for intuitive interaction. Designers can work with these in order to make interfaces intuitive to use, and thus help users to adapt more easily to new products and product types.

Solved problems are spline interpolation of points, zoom and pinch with transformation matrices, extensive history for action reversal and few basic tools.

This thesis empirically explores the influence of different types of naturally mapped control interfaces (NMCIs) for video games on the player experience and intuitive interaction. Across two repeated-measures experiments on racing and tennis games, more naturally mapped controls were shown to have largely positive effects, with some differences associated with player characteristics. The compensatory effects of natural mapping for casual players are revealed, along with some aversion to NMCIs amongst hardcore players. Overall implications are discussed, and a new NMCI Dimensions Framework presented, to aid future academic and design work leveraging NMCIs to improve video game accessibility and experiences.

This thesis investigates the feasibility of using gestures as a means of control for localizing three dimensional (3D) sound sources in a distributed immersive audio system. A prototype system was implemented and tested which uses state of the art technology to achieve the stated goals. A Windows Kinect is used for gesture recognition which translates human gestures into control messages by the prototype system, which in turn performs actions based on the recognized gestures. The term distributed in the context of this system refers to the audio processing capacity. The prototype system partitions and allocates the processing load between a number of endpoints. The reallocated processing load consists of the mixing of audio samples according to a specification. The endpoints used in this research are XMOS AVB endpoints. The firmware on these endpoints were modified to include the audio mixing capability which was controlled by a state of the art audio distribution networking standard, Ethernet AVB. The hardware used for the implementation of the prototype system is relatively cost efficient in comparison to professional audio hardware, and is also commercially available for end users. the successful implementation and results from user testing of the prototype system demonstrates how it is a feasible option for recording the localization of a sound source. The ability to partition the processing provides a modular approach to building immersive sound systems. This removes the constraint of a centralized mixing console with a predetermined speaker configuration.

Mobile manipulators are changing the way companies and industries complete their work. Untrained end users risk facing unfunctional and nonuser- friendly Graphical User Interfaces. Recently, there has been shortages of people and talent in the heathcare industry where these applications would benefit in being used to accomplish easy and low level tasks. All these reasons contribute to the need of finding functional robot-user ways of communicating that allow the expansion of mobile manipulation applications. This thesis addresses the problem of finding an intuitive way to deploy a mobile manipulator in a laboratory environment. This thesis has analyzed whether it is possible to permit the user to work with a manipulator efficiently and without too much effort via a functional graphical user interface. Creating a modular interface based on user needs is the innovation value of this work. It allows the expansion of mobile manipulator applications that increases the number of possible users. To accomplish this purpose a Graphical User Interface application is proposed using an explanatory research strategy. First, user data was acquired using an ad hoc research survey and mixed with literature implementations to create the right application design. Then, an iterative implementation based on code-creation and tests was used to design a valuable solution. Finally, the results from an observational user study with non-roboticist programmers are presented. The results were validated with the help of 10 potential end users and a validation matrix. This demonstrated how the system is both functional and user-friendly for novices, but also expressive for experts.<br>Mobilmanipulatorer förändrar sättet som företag och industrier utför sitt arbete. Otränade slutanvändare och särskilt de utan programmeringskunskap kommer att bemötas av icke-funktionella och användarovänliga grafiska användargränssnitt. Den senaste tiden har det varit brist på specialiserad personal inom hälsovårdsindustrin som har resulterat i ett beroende på dessa applikationer för att genomföra enkla uppgifter samt uppgifter på låg nivå. Alla dessa faktorer bidrar till det ökande behovet att hitta ett funktionellt sätt att kommunicera mellan robot och slutanvändare vilket tillåter expansionen av mobilmanipulatorapplikationer. Arbetet som beskrivs i denna avhandling adresserar problemet att finna ett intuitivt sätt att använda en mobilmanipulator i ett laboratoriemijö. Möjligheten att tillåta användaren att på ett enkelt och effektivt sätt arbeta med en manipulator via ett funtionellt grafiskt användargränssnitt analyseras. Innovationsvärdet och detta examensarbetes bidrag till nuvarande kunskap betraktar möjligheten att skapa ett modulärt gränssnitt baserat på användares behov. Detta möjliggör expansionen av mobilmanipulatörers applikation vilket ökar antalet möjliga användare. En förklarande forskningsstrategi används för att föreslå en grafisk användargränssnittsapplikation för att uppnå detta mål. Först användes data från ad hoc-undersökningar blandat med litteraturimplementeringar för att skapa den rätta applikationsdesignen. En iterativ implementering baserad på kodskapande samt tester användes sedan för att designa en värdefull lösning redo att testas. Slutligen presenteras resultat från en användarobservationsstudie med icke-robotikprogrammerare. De insamlade resultaten som samlades in under valideringsstadiet tack vare en grupp bestående av tio potentiella slutanvändare har analyserats genom användandet av en valideringsmatris som är baserad på tre parametrar. Detta demonstrerade hur systemet är både funktionellt och användarvänligt för nybörjare men också expressivt för experter.

The main aim of this study, in which 310 university students participated, is to investigate whether or not computer interfaces offering human-like apologetic error messages influence users&rsquo<br>self-appraisals of performances and actual performances in the computerized environment. For the study, an online instructional material which includes deliberate design problems leading to user frustration was developed. The study is comprised of three phases. In the first phase, based on the CCSARP (Cross-Cultural Study of Speech Act Realization Patterns) coding manual and the studies conducted with the framework provided by the manual, apology strategy sequences were elicited from Turkish participants. Two of these apology strategy sequences were selected for producing two apology error messages. In addition to these apology messages, one plain computer error message was also developed for experimental control. The second phase of the study was conducted to determine whether these three messages were perceived as apologies. It was found out that the two apology messages were perceived as apologies and the plain computer message was not perceived as an apology. In the third phase these three messages were used to investigate the relationship between mood, self-appraisal of performance and actual performance after the transmission of the apologetic error messages. The findings of this study show that the frequencies of apology strategies preferred in the computerized environment are similar with those utilized in the social context. Statistical analyses also reveal that the influence of apology messages on self-appraisal of performance depends on participants&rsquo<br>mood state and the contents of the apology messages.

碩士<br>國立成功大學<br>工業設計學系碩博士班<br>98<br>This study was based on the intuitive operation. Combining with tangible user interface (TUI), investigate the form of digital brush with intuitive operation that is suitable for 4-7 years-old children. Considering with the needs and cognitive ability of children, applying their tactile and visual abilities to learning in this period and convey the use by form. Through identify different patterns and observe the shape, change the brush intuitively and show more plentiful lines. The value of traditional drawing will be extended in the digital drawing. The first phase in the study is surveying painting status of 4-7 years-old children, through a questionnaire and user survey, summarizing the needs of children in the drawing and operating characteristics, defining system functions and control mechanisms. The second stage is brain storming, diverging the thinking of several intuitive operations and converging ideas into a workable program. The third stage is previous experiment, allowing users to practice and test those concepts. The final stage is the system performance test and subjective evaluation. The experimental results showed that the intuitive operation performance was superior to graphic user interface. Children can use the senses of tactile and visual to feel the texture and form, use the strokes smoothly with change grip position and angle. Second, they use plentiful strokes and improved significantly when using the digital brush with intuitive operation. Third, children get more fun in use and promoting the sustainable use of the will. Therefore, the intuitive operating TUI digital pen for children aged 4-7, is feasible to promote the use of digital drawing of the fluency, fun and learning.

This thesis addresses the need for adaptability in vision systems that measure system state information in a sensory feedback role for the control and coordination of flexible discreteitem materials handling operations, such as those performed by a robotic palletising system. In addition, this thesis addresses the need for vision systems that are more easily configured by users, such as factory technicians and operators, who have lower skill levels than those generally required to (re-)configure a machine vision system. In response, a unique coupling mechanism and intuitive human-computer interface have been developed, hiding the complexity of image analysis from the end-user and simplifying the way that a machine vision system is configured. The mechanism couples machine vision-related "visual checks” to materials handling tasks in a generic framework of materials handling activities. Visual checks which define what control information is required are implicitly linked to image analysis functions which define how that information is extracted from digitised images of a materials handling system. Consequently, this research has developed a set of task - visual check "building blocks" that can be used in various combinations to define the sequence of actions and image analysis required to perform a variety of materials handling operations. In addition, a number of pre-defined task – visual check combinations and mechanisms for manipulating them have been developed, providing solution templates that can be used immediately or modified to suit application-specific requirements. These developments have been realised together with several aesthetic, ergonomic and functional features in a machine vision configuration interface, known as SlyVision. SlyVision's modularity, extensibility and upgradeability expressed to both the end-user and the system developer through its underlying object oriented architecture and intuitive user interface design make important contributions to its overall adaptability. Demonstrations involving a typical palletising and a de-palletising operation have shown how SlyVlsion is used to specify visual checks and configure the associated machine vision components without requiring the end-user to select or apply image analysis techniques or functions. In addition, the relative simplicity of the configuration process is demonstrated. Consequently, these developments assist people with limited understanding of machine vision technology to set up and maintain a vision system, thereby improving their ability to keep pace with frequent changes in their materials handling operations, while limiting the cost in time, money and effort required to (re-)configure a vision system.<br>Whole document restricted, but available by request, use the feedback form to request access.

碩士<br>輔仁大學<br>應用美術學系碩士班<br>103<br>The elderly have deteriorating physical conditions and they have the gradual memory deterioration. Dementia is a progressive degenerative disease in which executive dysfunction is a core symptom that causes patients to be unable to sustain a normal daily life. If products are designed to strengthen the intuitive interaction of the product interface, then it will help elderly patients with dementia to live more independently. This study proposes a product interface design that is useful for intuitive operation by user groups comprised of elderly patients with dementia. This study identifies the requirements for intuitive operation of product interfaces from duration records, video observations of the analog interface, and observations from remote control prototypes. There were 27 subjects recorded in this simulation interface study. Six subjects were recorded by remote control prototype testing. The study results indicated the number keys were designed to be presented as separate buttons and this made them more likely to guide intuitive pressing operations in affordance with the needs of elderly patients with dementia. For example, when designing the volume and channel buttons on a remote control, the up and down keys should be separate. Additionally, the models should be simple and the buttons should be free of text but represented by symbols, because this will most likely allow elderly patients with dementia to perceive intuitive operation affordance.

A dissertation submitted in fulfilment of the requirements for the degree of Master of Digital Arts at the University of the Witwatersrand, Johannesburg, 2020<br>In the design and development industry, animation in the mobile interface is regarded as making interaction with mobile apps more intuitive. This study investigates the claim from the perspective of intuitive interaction research in Human-Computer Interaction (HCI), and Judgment and Decision making (JDM). The hypothesis is that animation in the mobile interface can influence how individuals integrate information, which is an underlying process of intuition. A wholly between-subjects design was used to test the relationship between animation, information integration, and judgmental evaluation. One hundred and fifty-two (152)participants were randomly assigned to either the experimental or control condition. The control condition is a replication of an experiment in automatic processing (Betsch, Plessner, Schwieren, & Gütig, 2001) and the experimental condition is an extension of this earlier work where animation is introduced as the independent variable. The results suggest that animation has a significant effect on how information is integrated and the resulting judgmental evaluations that were formed by participants<br>CK2021
