Recently, as one method of the game manipulation, physical interactive game is increasing, which controls the program by direct human movement. Tangible interface for physical interactive game implementation can control virtual model directly through real world object. A digital desk, one of the tangible interface, offers the interface that human can manipulate virtual object directly, by making projection screen on real world desk as computer display device. In this paper, we implement "Battle Region" game in the form of tangible interface, which can offer game users an efficient and amusing experiences by the use of physical interactive game. Traditional game cannot pursuit the diversity of game background contents but our game can do it through Map image projection. From this, game provider can supply the diversity of choice and users ran set up the difficulty of game. Therefore, our implemented game can offer users an efficient and amusing experiences by making game user's challenge and satisfaction maximum.

In this paper we Study a time-optimal model of pursuit in which the players move on a plane with bounded velocities. This game is supposed to be a nonzero-sum group pursuit game. The main point of the work is to construct and compare cooperative and non-cooperative solutions in the game and make a conclusion about cooperation possibility in differential pursuit games. We consider all possible cooperations of the players in the game. For that purpose for every game $\Gamma(x_0,y_0,z_0)$ we construct the corresponding game in characteristic function form $\Gamma_v(x_0,y_0,z_0)$. We show that in this game there exists the nonempty core for any initial positions of the players. The core can take four various forms depending on initial positions of the players. We study how the core changes when the game is proceeding. For the original agreement (an imputation from the original core) to remain in force at each current instant t it is necessary for the core to be time-consistent. Nonemptiness of the core in any current subgame constructing along a cooperative trajectory and its time-consistency are shown. Finally, we discuss advantages and disadvantages of choosing this or that imputation from the core.

In this paper, I proposed the general children's games and showed the design and implementation of children's games which are non-violent, emotionally helpful and good for the development of intelligence. I designed the user interface of the game for children, proposed relevant algorithms, and showed resultant screens of the game. Most of contemporary games are violent to children. To solve such problems, I designed and implemented the game which is not violent but educative and child-friendly. These days, entertainment games or Internet online games have been developed highly biased to children's interest and amusement rather than children's intellectual development. Usually, disabled children are inferior to normal children in movement of their hands and bodies. Therefore, it is hard for them to follow speedy games. This paper shows that the proposed intellectual development of the game can help disabled children not to be violent and to be more intelligent. That was proved by the results through the question investigation. According to the survey, disabled children's any violent actions were not reported after they played this game. Also, this game helped their intellectual development in accordance with the results of this study.

Recently, a wide range of next-generation's game consoles has been developed by many game makers. Particularly, active interaction between users and games is required more than ever before for giving gamers the fullest pleasure. In this work, an infrared image sensor based position recognition system which can be used for virtual game interface is proposed. Furthermore, two kinds of compensation algorithms and Extended Kalman Filter are utilized to enhance the performance of the proposed system. The proposed system can effectively generate the position of the gamer in the face of the coordinate distortion and noise. To verity the feasibilities of the proposed system, various experiments are carried out.

In this paper, a network based robot soccer system is proposed. The system consists of robots, an image processing sub-system, a game server, and client systems. Embedded technique is applied to the hardware and software for controlling the robots and image processing. In this robot soccer system, a gamer can see and control robots in a remote site through Internet. During the game, the game server gives geometrical information on robots such as positions and orientations. We demonstrated the game in public and obtained optimistic results even though some technical problemssuch as communication delay and precise control for the robots should be improved.

Purpose: The purpose of this study was to examine the effects of EP-IGAP(Internet Game Addiction Prevention Educational Program) on increasing the self-control and decreasing the time spent on internet games. Method: The research design was a quasi-experiment, repeated measures design with non-equivalent control group. Participants in this study were 269 elementary school students of elementary school(134 for the experimental group, 135 for the control group). The instruments used in this study were the Self-control of Internet Game Scale and Time spent on internet games per week. The experimental group participated in the EP-IGAP for 6 weeks. Results: After the intervention, the experimental group showed a significant increase in self-control related to internet games. But, there was no statistical difference in the time spent on internet games between the two groups. Conclusion: These results suggest that EP-IGAP is effective in increasing the self-control related to internet games in elementary school students. Further research is needed to modify the EP-IGAP.

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.
