In this paper, we propose CIVE, context-based interactive system for heterogeneous distributed virtual environments that delivers contexts irom real world to virtual environment and vice versa. The proposed system ronsists of obi-UCAM for generating user's contexts, NAVER for managing virtual environment, and Interface for linking obi-UCAM with NAVER. The connection between real and virtual worid through context is brneficial in following ways. Firstly. CIVE Provides a personalized user interface for virtual environment according to a user profile such as identity, age and vernacular. Secondly, translating all input signals into context, it guarantees adaptive access that enables a user to exploit unencumbered input devices controlling a shared object in virtual environment even if he moves with his own device from a virtual system to another. Finally, it provides a mechanism for synchronizing distributed virtual systems that share context representing changes at remote nodes. The context reduces the inconsistency of representing the same data among heterogeneous systems. Therefore, CIVE plays an important role in implementing VR applications such as teleconference, game and entertainment.

This study evaluate user feedback such as physiological response and facial expression when subjects play a social decision making game with interactive virtual agent partners. In the social decision making game, subjects will invest some of money or credit in one of projects. Their partners (virtual agents) will also invest in one of the projects. They will interact with different kinds of virtual agents which behave reciprocated or unreciprocated behavior while expressing socially affective facial expression. The total money or credit which the subject earns is contingent on partner's choice. From this study, I observed that subject's appraisal of interaction with cooperative/uncooperative (or friendly/unfriendly) virtual agents in an investment game result in increased autonomic and somatic response, and that these responses were observed by physiological signal and facial expression in real time. For assessing user feedback, Photoplethysmography (PPG) sensor, Galvanic skin response (GSR) sensor while capturing front facial image of the subject from web camera were used. After all trials, subjects asked to answer to questions associated with evaluation how much these interaction with virtual agents affect to their appraisals.

This study proposes a novel approach to enhancing the social inclusion and participation of individuals with developmental disabilities. Utilizing cutting-edge virtual reality (VR) technology, we designed and developed a metaverse simulator that enables individuals with developmental disabilities to safely and conveniently experience indoor handicapped handball sports. This simulator provides an environment where individuals with disabilities can experience and practice handball matches. For the modeling and animation of handball players, we employed advanced modeling and motion capture technologies to accurately replicate the movements required in handball matches. Additionally, we ported various training programs, including basic drills, penalty throws, and target games, onto XR (Extended Reality) devices. Through this research, we have explored the development of immersive assistive tools that enable individuals with developmental disabilities to more easily participate in activities that may be challenging in real-life scenarios. This is anticipated to broaden the scope of social participation for individuals with developmental disabilities and enhance their overall quality of life.

At first there was practice, then festivals and theory followed. Compared to the animation production, which is older then the medium film itself, festivals and theory in this area started with a delay. While animation programs where shown in film festivals like Cannes since the mid 1940s, the first animation festival in Annecy, France was founded in 1960, followed by several short-lived events in Romania, Italy and Tokyo and finally in 1972 by the second oldest festival up to date, Animafest Zagreb. Animation theory evolved in the late 1980s in the Anglo-American area with associations like the Society for Animation Studies, following its 'big sister' film studies. Expanding ever since as a research area, European animation studies in e.g. France, German speaking countries, Poland or Croatia have been catching up in recent years by organizing theoretical conferences and publications. A vivid synergy between practice, festivals and theory has always been a key factor for establishing a platform for the art form and culture of animation. However, in the past few years a trend could be observed towards a more intense interaction between animation festivals and theory. Animation festivals are hosting theoretical and scientific symposia or conferences, which are open for artist positions and insights into the industry. At the beginning of the lecture a short reflection of the concept of Animafest Scanner itself is followed by an introduction of the Symposium Expanded Animation at the media festival Ars Electronica Linz. The talk will subsequently focus on the multilayered academic symposia at the Festival of Animated Film ITFS and the International Conference on Animation, Effects, VR, Games and Transmedia in Stuttgart. These case studies will reveal the blurring boundaries between art, science, theory and industry as well as the specificities of the interplay between artists, practitioners, scholars, curators and festival visitors in different formats.

Rapid growth in computer and digital-based technology has brought about changes in various human services including psychotherapy. This paper will look into one of these changes, focusing on a rising area of mental health therapy : Art therapy. Although development of art therapy is not so fast compared to other branches of psychotherapy, some art therapists are studying how to adopt and use it properly. Both art therapists and mental health experts have concluded that technology is a powerful tool despite its limitations and reservations. While some of them think that patients have benefited from the implementation of technology, others have felt concerns about the replacement of basic professional practices. The use of digital technology in the area of art therapy, however, continues to increase, encouraging patients to benefit from it in various therapeutic processes. This thesis therefore focuses on the analysis of literature related to digital art therapy published up to now. The following field study on Korean art therapists aims to examine the current practice of digital art therapy and discuss its feasibility and future. These two methods will contribute to enhancing the understanding of art therapy not only in theory but in practice and also suggest how digital art therapy may overcome limitations of conventional art therapy by exploiting its advantages. Furthermore, this study will present some clues on a possible new position of digital art therapy in the future. I hope that this analytical examination on digital art therapy will stimulate further discussion on this issue and particularly encourage more interdisciplinary work between art therapy and digital technology.

Cartoons and consequently animation are an effective way of visualizing futuristic scenarios. Here we look at how animation is becoming ubiquitous and an integral part of this future today: the cybernetic and mediated society that we are being transformed into. Animation therefore becomes a form of speech between humans and this networked reality, either as an interface or as representation that gives temporal form to objects. Animation or specifically animated films usually are associated with character based short and feature films, fiction or nonfiction. However animation is not constricted to traditional cinematic formats and language, the same way that design and communication have become treated as separate fields, however according to $Vil{\acute{e}}m$ Flusser they aren't. The same premise can be applied to animation in a networked culture: Animation has become an intrinsic to design processes and products - as in motion graphics, interface design and three-dimensional visualization. Video-games, virtual reality, map based apps and social networks constitute layers of an expanded universe that embodies our network based culture. They are products of design and media disciplines that are increasingly relying on animation as a universal language suited to multi-cultural interactions carried in digital ambients. In this sense animation becomes a discourse, the same way as Roland Barthes describes myth as a type of speech. With the objective of exploring the role of animation as a design tool, the proposed research intends to develop transmedia creative visual strategies using animation both as narrative and as an user interface.
