    Recent emerging technology with a Virtual Reality (VR) aspect is very research-driven as well as successful in commercial devices. Within it, the most advantageous technology is the Oculus Rift headset because of its light-weight, low-cost and high quality, which has potential to bring novel VR theory into practice. Furthermore, Leap Motion has emerged as a high precision bared hand tracker which supports VR integration. Thus, the combination of these technologies is promising in many application areas. Gaming is one of these, particularly the life simulation game genre because gaming not only bridges users to familiar technology but also gives them full immersion into the synthetic world. Among the many successful simulation games, the digital pet raising game genre has proven itself in the gamers’ community as well as in relation to advances in motion controller games. This has motivated the development of a virtual reality pet game. So, this research envisages to develop a prototype of a pet-raising game using the Unity game engine based on Leap Motion and Oculus Rift technologies. The prototype contains a variety of pet interactions including feeding, cleaning, throw-catch, tricks training, etc. to enhance the hand motion controlling of Leap Motion as well as playing with first person perspective to give full immersion in terms of VR. After that, the importance of game evaluation is justified via quantitative research approaches, aming to investigate into the interactive technologies like Leap Motion. Kinectimals game based on Xbox Kinect technology, was selected to compare two games in terms of motion controlling similarity. Two experiments which are similar procedure on the developed game and Kinectimals, are conducted in order to collect objective measures such as duration, task and failure rate; plus participant’s subjective reporting following three questionnaires, the After-Scenario Questionnaire (ASQ), IBM computer usability satisfaction questionnaire (CSUQ) and NASA-Task Load Index (NASA-TLX). Those questionnaires included standard questions and additional questions which are specific design for the prototype. Comparing to Kinectimals, the game achieved a high acceptable score in terms of workload, information and interface quality satisfaction. The final prototype received much positive feedback without simulator/motion sickness during long term playing and interface design. Moreover, beside the rich content game playing, some hand gestures including fist, face-up hand, throw-grab activities were the most reliable using Leap Motion. However, hand tracking issues were identified due to the lack of robustness, particular in dynamic gestures. As a result, main contribution is to make VR more accessible to ordinary people via gaming as well as how to apply the immersion into a specific game genre. In spite of some games/applications based on these technologies combinations, the serious experiments verifying their feasibility are limited, which makes this research worth to carry on. The experiment’s findings it is hoped contribute to promoting the pet game genre within a VR setting, in particular immersion role and motion controlling

    Düzenli spor yapmanın yaşam ve sağlık kalitesi için yararlı olduğu kabul edilmektedir. Fakat düzenli spor yapma olanaklarının özellikle gelişmekte olan ülkelerde yeterince yaygınlaşmadığı gözlenmektedir. İnternet ve Kinect gibi güncel ve gelişmiş teknolojilerin sağladığı olanaklar ile, spor yapamayanlara fiziksel olarak aynı ortamda bulunmaksızın, sanal eğitmen kontrolünde spor yapabilme olanağı sunmanın alternatif bir çözüm yaratabileceği düşünülmektedir. Bu doğrultudaki çalışmalarla, Kinect üç boyutlu sanal spor platformu tasarlanıp geliştirilmiştir. Geliştirilen platformun özellikleri, yeni teknolojilerin avantajlarının kullanıldığı platformlar ile alternatif spor yapma olanakları gözden geçirilmektedirRegular sports activity is considered to be beneficial for life quality and health. On the other hand, regular sporting opportunities are not widespread, especially in developing countries. It may be possible to provide an alternative solution for physical activity in the control of a virtual instructor, without being physically in the same place, thanks to the facilities provided by technologies such as Internet and Kinect. In this respect, the three dimensional virtual sports platform Kinect was designed and developed. The different features of the platform are described, and the advantages of new technology achievement and possibilities of alternative sports practice are give

    According to Krashen's affective filter hypothesis, students who are highly motivated have a strong sense of self, enter a learning context with a low level of anxiety, and are much more likely to become successful language acquirers than those who do not. Affective factors, such as motivation, attitude, and anxiety, have a direct impact on foreign language acquisition. Horwitz et al. (1986) mentioned that many language learners feel anxious when learning foreign languages. Thus, this study recruits 100 college students to fill out the Foreign Language Classroom Anxiety Scale (FLCAS) to investigate language learning anxiety. Then, this study designs and develops an affective tutoring system (ATS) to conduct an empirical study. The study aims to improve students’ learning interest by recognizing their emotional states during their learning processes and provide adequate feedback. It is expected to enhance learners' motivation and interest via affective instructional design and then improve their learning performance

    This study focuses on the design and development of Virtual Taekwondo Training Environment (VT2E) prototype as a supplementary material for self-directed Taekwondo training. Even though there are varieties of supplementary Taekwondo training materials available, most of them have limitations in supporting self-directed training. The results of the preliminary study clearly indicated the importance of self-directed Taekwondo training among the trainees and they are facing problems while performing self-directed training at home since they do not have proper supplementary training materials to guide them. Thus, the research aims to propose the VT2E prototype as a supplementary material for self-directed Taekwondo training which incorporates Virtual Reality (VR) and Motion Capture (MoCap) technologies which is to study the trainees’ satisfaction in terms of Engaging, Presence, Usefulness and Ease of Use. The methodology of this study consists of three phases, namely; information gathering, prototype design and development and evaluation which is adapted from Vaishnavi and Kuechler (2008). In providing a useful and effective training material, the prototype incorporates the Constructivist Theory and Theory of Flow. Perception, Pearson Correlation and Regression analyses were used to determine the effects of Engaging, Presence, Usefulness and Ease of Use on trainees’ Satisfaction in using the VT2E prototype. The results provided empirical support for the positive and statistically significant relationships between usefulness and ease of use on trainees’ satisfaction. However, Engaging and Presence did not have positive and significant relationships with satisfaction. As for the conclusion, this study has looked into the possibility of introducing a new approach of training through the use of the two technologies. It is hopeful that this prototype can be a guide for self-directed Taekwondo training in enhancing the skills and performances and indirectly fullfil the trainees’ satisfaction

    Emphasising the alien qualities of anthropomorphic technologies, Machine Sensation makes a conscious effort to increase rather than decrease the tension between nonhuman and human experience. In a series of rigorously executed cases studies, including natural user interfaces, artificial intelligence as well as sex robots, Leach shows how object-oriented ontology enables one to insist upon the unhuman nature of technology while acknowledging its immense power and significance in human life. Machine Sensation meticulously engages OOO, Actor Network Theory, the philosophy of technology, cybernetics and posthumanism in innovative and gripping ways

    The Interface is Obsolete: A Critical Investigation of the Digital interface in Interactive New Media Installations

    My thesis proposes a critical framework for understanding the digital interface in interactive new media installations. I aim at dispelling the instrumental, cybernetic, “action-reaction” myth that surrounds the functions of the interface and that constitutes one of the main limitations in its conceptualization today. I argue that a rethinking of the digital interface in terms of its aesthetic and cultural properties is essential if we are to take digital interfaces seriously as devices that inform or even, to some extent, structure our relationship with technology. Theorists who work in the interdisciplinary field of interface studies have historically been preoccupied with the technical and instrumental functions the interface performs – specifically with how it acts and reacts to pre-programmed information. To do this, they have predominantly drawn on computer science and engineering perspectives. Thus digital interfaces have commonly been understood as the symbolic software that enables humans to use computers. My thesis approaches the digital interface from a different direction, concentrating on the aesthetic and cultural aspects of the digital interface, and drawing on scholarship from the fields of art history and media studies. In particular, I focus on critically examining how various interfaces are defined within art environments and how they influence the way subjects, objects, and the relationships and processes that exist between them are understood in these disciplinary fields and practices. Throughout, I propose a more expansive definition of the digital interface in interactive new media installations, positioning it as a dynamic, hybrid, aesthetic and cultural process. I thus reformulate the problem of the digital interface as a problem of making the often invisible aspects of the device legible. Ultimately, I argue that the interface mediates, thus creates, to an extent, relationships between viewer/participants, artists and artworks as well as influences the movements and perceptions of those interacting with it. This reading enables me to conclude that the digital interface can be seen as an important actor in positioning and (re)shaping specific ways in which the self relates to technology, to artistic practice and to other human and nonhuman beings in the current media culture. At the heart of this thesis is the notion that the digital interface matters and that a critical exploration of it in aesthetic contexts can help us understand and possibly reconfigure our human relationship with technology
