The need of high quality VR contents has been steadily raised in recent years. Therefore, this study investigated the user's interest factors of VR game which is receiving the most attention among VR contents. We used STEAM review data and applied Text mining and Network analysis to perform this research. As a result, it was possible to confirm 4 word clusters related VR game users. Each cluster is named by 'presence', 'first person view game', 'auditory factor' and 'interaction'. This study has its meaning. First, user related research would be very helpful to develop high quality VR game. Second, it confirms that review data of VR game users can be structured, analyzed and used.

Recently in the gaming market, immoral game behaviors such as flaming, trolling, and illegal program use have drawn attention as serious problems. With 209 gamers of , this study analyzed the effects of perception toward in-game rules, social identity, moral identity, and moral positioning with control of gender and gaming time. Results showed that moral identity and formal moral perception toward in-game rules had positive effects while moral positioning and social identity had negative effects on immoral behavior. Notably, moral identity had interaction effect with moral positioning.

Recently, Many 3D augmented reality games that provide strengthened immersive have appeared in the 3D game environment. In this article, we describe a barehanded interaction method based on human hand gestures for augmented reality games. First, feature points are extracted from input video streams. Point features are tracked and motion of moving objects are computed. The shape of the motion trajectories are used to determine whether the motion is intended gestures. A long smooth trajectory toward one of virtual objects or menus is classified as an intended gesture and the corresponding action is invoked. To prove the validity of the proposed method, we implemented two simple augmented reality applications: a gesture-based music player and a virtual basketball game. In the music player, several menu icons are displayed on the top of the screen and an user can activate a menu by hand gestures. In the virtual basketball game, a virtual ball is bouncing in a virtual cube space and the real video stream is shown in the background. An user can hit the virtual ball with his hand gestures. From the experiments for three untrained users, it is shown that the accuracy of menu activation according to the intended gestures is 94% for normal speed gestures and 84% for fast and abrupt gestures.

Interaction is an important component in the sense of immersion in augmented reality. However, the function of interaction in augmented reality contents is very weak. Bringing a lot of real environmental information is one of the ways to develop augmented reality, and interaction will naturally develop. In this paper, Leap Motion was used for natural interaction in augmented reality environment through the hand widely used as an interface tool, and extended more from the limited interaction of conventional display touch methods to create a natural interaction. This development of interaction will contribute to the development of various contents as well as augmented reality later.

In this paper, we develop a haptic mouse system for immersive human computer interaction. The proposed haptic mouse system can provide vibrotactile feedback as well as thermal feedback for realistic virtual experience. For vibrotactile and thermal feedback, we use eccentric motors, a solenoid, and a peltier actuator. In order to evaluate the proposed haptic mouse, we implement a racing game prototype system. The experimental result shows that our haptic mouse is expected to be useful in experiencing virtual world.

A technology roadmap was developed for haptic interface technologies to be applied to games. Haptic interface technologies are expected to play an important role in games to provide gamers with interaction and immersive perception in near future, even though haptic interface technologies have been less studied than other perception-related technologies with respect to games. Information on two types of haptic interfaces - portable and desktop - and their evolution processes were analyzed in terms of technological demands. Haptic feedback technologies to realize these demands were inspected with the time frame and haptic feedback technologies were derived using a technology tree. The technology roadmap of haptic interfaces in game was finally constructed by mapping the technological demands in time with game technology trends. The technology roadmap of haptic interfaces will have implications on developing haptic interfaces to be applied to many applications including virtual realities and games.

In order to ensure the wireless connectivity and seamless service to mobile users, the next generation network system will be an integration of multiple wireless access networks. In a heterogeneous wireless access system, bandwidth allocation becomes crucial for load balancing to avoid network congestion and improve system utilization efficiency. In this article, we propose a new dynamic bandwidth allocation scheme for hierarchical wireless network systems. First, we derive a multi-objective decision criterion for each access point. Second, a bargaining strategy selection algorithm is developed for the dynamic bandwidth re-allocation. Based on the intervenient Stackelberg game model, the proposed scheme effectively formulates the competitive interaction situation between several access points. The system performance of proposed scheme is evaluated by using extensive simulations. With a simulation study, it is confirmed that the proposed scheme can achieve better performance than other existing schemes under widely diverse network environments.

현재 게임 역사를 보면 조이스틱의 인기가 눈에 띄게 떨어졌음을 알 수 있다. 비행 시뮬레이션 장르의 게임의 수가 적어지고 있기 때문이다. 조이스틱들은 일인용 슈팅 게임을 지원하지만 마우스나 컴퓨터 키보드에 견주어 보면 정확성이 떨어진다. 최근에 나온 소수의 게임들은 콘솔 PC와 연계가 되지만 PC 사용자들에게 자동 발사 기능을 사용할 것을 요구함으로써 사용자들에게 불편을 주었다. 본 연구는 기존의 게임 컨트롤러 구성요소를 분석하고, 아동의 조작능력과 신체발달과의 상호관계를 통해 아동의 놀이 발달기별 특징에 적합한 게임 컨트롤러를 개발한다는 것을 목적으로 한다.
