This research examined the effects of user experience in driving simulation game between using general monitor and 3D virtual reality device, Oculus Rift DK2. We compared the difference of user experience such as presence, flow and arousal by gaming environment. We also tested the effects of virtual reality on driving attitude, emotional pleasure and satisfaction. 100 beginner drivers with a driver's license participated in the experiment of two modes of gaming environment. As a result, all the three user experiences were proved to be significantly higher in VR game play than general monitor game. Also driving attitude, emotional pleasure and satisfaction showed a significant difference in virtual reality. This study makes a theoretical and practical contribution to the application of the next virtual reality game with a special function.

This study attempted to identify differences in user experience such as spatial presence, social presence, flow, empathy, anxiety, and perceived risk between simulating characters of animation and of actual userimage. The playtesting method was conducted on 60 male smokers using 'Smoking Sims', a simulation game produced by The Center for Health Communication Studies. The results found that the simulation of actual image character is higher in the level of perceived risks for smoking, spatial presence, social presence, flow, and empathy than the simulation of animation character. The study shows that identification with a game character affects user experience and enhances the effectiveness of perceived risks as well. It emphasizes the importance of game design to implement identification in serious game like a smoking cessation simulation.

The interaction between users and games is an important factor in game development. In this paper, we consider Leaderboard UI in shooting game and study user's performance level according to presence or frequency of providing Leaderboard UI. For this research, we developed a third person shooting game and conducted experiments for 80 college students. The results of the experiments were analyzed using statistical significance using the T-test method. Finally, in order to improve user's performance level, we conclude that the user's gaming experience is a bigger factor than the presence or frequency of providing Leaderboard, causing a significant difference.

In recent, mobile augmented reality game which has been attracting high attention is considered to be an good approach to increase immersion. In conventional augmented reality-based games that recognize target objects using a mobile camera and show the matching game characters, touch-based interaction is mainly used. In this paper, we propose an intuitive interaction method which manipulates a deformable game object by moving a target image of augmented reality in order to enhacne the immersion of the game. In the proposed method, the deformable object is intuitively manipulated by calculating the distance and direction between the target images and by adjusting the external force applied to the deformable object using them. In this paper, we focus on the cloth deformable object which is widely used for natural object animation in game contents and implement natural cloth simulation interacting with game objects represented by wind and rigid objects. In the experiments, we compare the previous commercial cloth model with the proposed method and show the proposed method can represent cloth animation more realistically.

Today, most of games permit interaction between user and game freely. Therefore it is difficult to progress the story-line of the primary stage. Especially in educational game surroundings, we have more difficulties in achieving original purpose of education. In this paper, we proposed the applied model of mini-game which was inserted into main-game in order to control interaction between user and game. On the basis of this model, we derived valuation elements by mini-game implementation types from developing the educational game in which involved mini-game. We looked around whether the educational game achieved the educational goal of first stage or not. Comparing with some excellent ones picked up by public authorities, we evaluated the educational game. As the result of evaluation, we could find that the application of mini-game had very high effectiveness in attainment of teaming goal, studying of well-balanced, and induction of learning motivation. And we found that the application also had very affirmative effect to the practical objects of primary stage in overall sphere.

Cases of applying game in the medical area are increasing thesedays. This game has been developed to prevent disease in self-nervous system through the control of respiration after monitoring the mental stress and physical stress from the heart rate variability (HRV) of the game user. The game is a kind of a stress relaxation program (SRP) designed not to avoid boring or rejecting mind of users by traditional simple training of continuous repetition, but to increase interaction which is a unique feature of games.

With the development of wireless Internet technology and the expansion of the game market, various forms of games are being developed that are mounted on various platforms, including mobile platforms. In this environment, ensuring the immersion of the game user's perspective will secure the game's competitiveness, so it is necessary to increase the immersion by satisfying each area presented by the Human Computer Interaction (HCI) theory. To this end, this high school implemented downhill games and experimented with kiosks by applying an interface that recognizes the human body's movements as a way to secure freedom and immersion of game users.

Purpose - The purpose of this paper is to investigate the effects of online game properties, social interaction, and player satisfaction on intention to online games in Chinese gamers. Research design, data, and methodology - This study is an empirical analysis assuming that properties of online games, social interaction and satisfaction will induce Chinese gamers' intention to play online games. We set the relationship between the six variables as follows. First, the properties of online games, exogenous variables, were identified by three factors: entertainment, security, participation and challenge. Second, we had input social interaction among gamers as another exogenous variables. Third, the gamer's satisfaction of online games was added to the research model as a mediating variable between exogenous variables and endogenous variables. Finally, gamer's intention to play influenced by satisfaction and social interaction was used as final endogenous variable. The data used for the empirical analysis were collected through questionnaires for Chinese under age 35 who enjoy the online games. The data used in the research were finally extracted from 195 questionnaires. The collected data were tested through the analysis of the measurement model (Step 1) and the analysis of the structural model (Step 2). The covariance structure equation model (SEM) was used for the analysis. The measurement model and structural model were evaluated by the maximum likelihood method. Results - The results of the empirical analysis are as follows. The satisfaction of online games were entertainment and security had a significant effect to satisfaction; but participation and challenge and social interaction had no significant effect on satisfaction. The social interaction among gamers and the satisfaction with online games have a significant influence on the intention to play online games. As a result, the attributes of the game were affecting the intention to play the game after satisfaction. Social interaction influenced the intention to play online games rather than satisfaction itself. Conclusions - This study provide some practical implications for the new companies who want to enter the online game industry and seek to competitiveness in China, and provide theoretical implications on the role of interaction among gamers in the study of online games.

Presence, flow, and arousal are interesting user experiences provided by video and people's demand for media which responds to personal interest is getting strong. This research compares video watching and game play by conducting a survey and measuring brain wave to find out the difference of those user experiences in the two media. As a result, all the three user experiences were proved to be significantly higher in game play than video watching. And those EEG frequencies which are known to be related to the state of flow were also measured higher scalp distribution of the game play group. Finally, presence, arousal, and EEG(${\alpha}$, ${\beta}$, ${\delta}$) were found to have influence on the flow state in game play. This research is intended to prove above relations by experiment and make a contribution to the theoretical and methodological improvement in the related area.
