This study focuses on the play aspect of the existing digital games and VR games as part of a basic research for facilitating discussion on VR games. As a method for this research, the play aspect of digital games was classified based on the play theory by Johan Huizinga and Roger Caillois, followed by examination on the play characteristics of VR games according to the established classification. As a result, VR games share a significant portion of play characteristics with digital games. Nevertheless, in VR games the player is allowed unimpeded physical activity while having the HMD on and complete disconnection from the real world via new input/output devices. In the end, the transformation of play environment results in various sensory stimulation, and in turn influences the player's experiences in areas such as presence, immersion, emotional enjoyment and satisfaction. This study is expected to serve as an important indicator for studies on the characteristics of VR contents which is certain to develop in a wide range of directions in the future.

In this paper, we implement a digital content that visualizes 33 Avalokitesvara-Bodhisattva according to the wishes of the public. The 33 Avalokitesvara-Bodhisattva is described in the Avalokitesvara-Bodhisattva tale that is found in the ancient literature "Memorabilia of the Three Kingdoms" as Tangible Cultural Heritage. Also, it is easily found in a wall painting of traditional Buddhist temples. The 33 Avalokitesvara-Bodhisattva is the saint of mercy that transforms into 33 various forms according to the wishes of the public. The Avalokitesvara-Bodhisattva tales deal with differences in the types of wishes of the public, and the tales have been speeded like wildfire among the people. So, in this paper, we classify them into 4 groups by the wishes (healing, security, academic achievement, disaster relief) of the public, and then analyze its symbolism and activity of the 33 Avalokitesvara-Bodhisattva. Also, we implement a 2D digital content that represents visually it according to the wishes of the public. Applications of the implemented visual content are as follows; development of character, game, and digital storytelling associated with traditional culture, education service for Buddhist doctrines, etc.

In computer graphics, fluid dynamics are used for animating and expressing the various special effects of water. Although the algorithms that were impossible through the hardware at that time become to be possible in real time, it still requires a lot of time to achieve the realistic and detailed expressions. Therefore, there are many researches on the techniques of balancing between performance and quality. Specially in environments with the game context which express the interaction between water surface and 3D objects in the wide area such as sea or lake according to user's request, it must give priority to the executive performance preserving the visual reality even though physical reality is sacrificed. In this paper, we propose a method for the realtime animation of interaction between water surface and 3D objects using the linear convolution of height fields and the bounding spheres of objects.

In this paper, we implemented a user - oriented adaptive English typing program using class and function structure provided by Python to get English learning effect while effectively typing English on PC. The user of the implemented English typing program creates a text file of required English example sentences and links them to use it for direct English typing exercise. In addition, based on the English sentence used in the English typing exercise, it is possible to obtain the English learning effect by providing the ability to perform the memorization test. The interface of the program is structured in the form of a game so that it can be accessed interestingly, and the ranking among the users is disclosed to provide a positive function. We expect that the implemented program will improve the user's English typing speed and improve the English learning effect.

While various artistic trends coexisting in the 20th century, media arts that formed with the medium of a material attempts in various ways to induce the establishment of the artwork through the public communication. The visual arts that use the media satisfy both the artistry and the popularity in the area of popular culture as the form of variable. Moreover, visual arts stimulate a playful sense of human to maximize the public satisfaction that works here. This paper aims to discuss the potentials and the trends in the contemporary art by understanding the conceptual and principle background of the contemporary media art which shows the active employment the playful sense of human nature in the work in order to establish the effective communication with the public. Consequently, as the digital environment and advanced network technology which were thought to be the key elements of the popularization of media art were reached its limit, media artist, Tony oursler's artwork which was created based on human playful nature and interactive artwork that supports the audience to interact with artwork and its space are proven to be the useful devises for the public communication.

In recent years, micro-blogging services such as 'Twitter' and 'Me2day' have rapidly become major social networking services. However, it is difficult to grasp the relationship between a user and his/her friends in these micro-blogging services because they simply list messages between them in chronological order. In this paper, we propose a visual analytics system that can help the user intuitively understand relationships with their friends on micro-blogging services by enabling them to analyze the messages quantitatively, qualitatively and temporally. In the visual analytics system, we also present a tool to provide the user with valuable advices after classifying the changing relation patterns with his/her friends, which in turn contributes to improving relationships with friends. The proposed system was successfully implemented as smartphone applications to show its potential to be a tool for analyses and improvement of social relations in micro-blogging services.
