As virtual reality technology has gained popularity from people, various contents have appeared. Virtual reality game making good use of virtual reality device has received lots of attention from users and market. A number of virtual reality games have been developed. Virtual reality game allows users to feel presence and flow to be maximized through virtual reality device. A user can interact with several items through interface of device in display environment of virtual reality. This study was find a way to arouse an interest and induce users to be immersed in virtual reality game by maximizing above mentioned characteristics. This study was analyze interaction items in popular virtual reality game and interface design methods before presenting design methods. This study was make a comparative analysis of interface design methods centering on virtual reality game cases and examine a link between interface and interaction items. Through this study, it is expected that this will be a prior study that will be the basis for designing interfaces for virtual reality games that are more presence.

Virtual reality technology is recognized as a next-generation technology and can create realistic environments like the real world and reproduce sensory experiences. And it is a cutting-edge technology that allows humans to experience the same real-world experience in a virtual world by computing the five senses with computers. Also Virtual reality is a technology that has the advantage of experiencing reality in cyberspace and is applied to content such as movies and games. However, many users who use virtual reality can feel cybersickness. And it especially in virtual reality games. This is an important issue for the virtual reality game industry to be resolved. Main symptoms of cyberscickness include dizziness, headache, and vomiting. Existing motion sickness and symptoms are similar, but the cause of cybersickness is different from traditional sickness. Therefore, this study uses virtual reality games and data from various organizations to determine the causes of cybersickness. Also, it intends to contribute to the development of the virtual reality game industry by presenting methods to supplement these problems.

HMD makes big issues about virtual reality in these days. Experience of virtual reality may cause different effects with experience of real world, so this is the reason why comparison studies are needed. There are many works about usefulness of virtual reality education but most of studies were considered as special training. This study was started for the long term memory effect of virtual reality education game. Difference study of memory between real world education game and virtual reality education game shows virtual reality system has smaller diminution of memory than real world. And environment existence was defined as a main effect of long term memory through the test.

This study aims to analyze remediation of games and fictions in Korean virtual reality game fictions and to derive the storytelling of virtual reality game fictions through them. The purpose of this study is to explore the possibilities that Korean game fiction based on the web can be expanded as popular literature. The main character of the fiction is a male in his twenties. In the neoliberal society, he is set as a member of the neglected class and lacking privilege. He enters the virtual world because of the deficiency experienced in the real world. It minimizes the mediation process between the real world and the interface. On the other hand, the repetitive actions performed by the protagonist belong to the category of self - destructive labor. As a result, he shows signs of narcissism. In the Korean virtual reality game fiction, the magic circle appears blurred, and the real world and the virtual world are linked. In this process, the virtual world functions as a substitute space to solve the problem of reality. The establishment of such a space, and the resolution of conflicts are merely narrative characteristics of Korean game fictions that are different from North America and Europe.

Virtual reality can user experience the virtual world of computer and stimulate user eyesight and emotions. HMD can acquire and stimulate user behavior and sensory information. In this paper, we propose a virtual reality game using robot control. Controlling the robots using various interfaces and synchronizing them with the virtual reality game. In this paper, we use OID mat for robot movement detection based optical code recognition and Kalman filter.

Purpose : This study investigated the effect of 4 weeks training of virtual reality game on balance and gait ability, depression of elderly people. Methods : The subjects of this study were 12 elderly people over 65 age. The subjects were treated by training using virtual reality gam (during 60 minutes, 3 times a week for 4 weeks). The results of the experiment were analyzed using paired T-test along with averages and standard deviations as the statistical methods for data analyses. Results : In comparison of depression, gait and balance ability between pre-test and post-test, there were statistically significant differences. Conclusion : Our study finding indicate that training using virtual reality game could improve balance and gait ability, depression in elderly people. According to our study, training using virtual reality game is judged to be used for elderly people with gait and balance problems, depression to prevent fall down.

Backed by the fourth industrial revolution as the background of the research, VR, AR and MR have increased interest and wireless Oculus Quest is releasing, creating hardware recall and continuing virtual reality devices, and game software develop or service VR games using such devices. As a result, it is expected that VR game markets will continue to grow in the future. For this purpose, we understand the technical factors of presence and immersion that appear in virtual reality games and should be able to apply them when we produce VR games. Through the process, we analyzed elements of VR game concept, immersion, and presence and analyzed three games that were commercialized. As a suggestion, we need to take into account presence and immersion characteristics when developing and experiencing virtual reality games in the future.

In this paper, we implemented online real time strategy game using hand as the mouse in augmented reality. Also, we introduced the algorithm for detecting hand direction, finding fingertip of the index finger and counting the number of fingers for interaction between users and the virtual objects. The proposed method increases the reality of the game by combining the real world and the virtual objects. Retinex algorithm is used to remove the effect of illumination change. The implementation of the virtual reality in the online environment enables to extend the applicability of the proposed method to the areas such as online education, remote medical treatment, and mobile interactive games.

Recent years have witnessed a surging popularity of games based on augmented reality and virtual reality. While old games embody virtual reality within the game platform, recent popular games based on augmented reality and virtual reality incorporate reality into virtual worlds. They present a new genre that is unprecedented, combined with what gamers have a passionate desire for, and thus provide new experiences. Good examples include smartphone games that were the game changer of the gaming industry in 2010 and the sensational $Pok{\acute{e}}mon$ Go that is gaining popularity nowadays. This study, thus, set out to analyze "gaming act(GA)" directly connected to the experiences of gamers to shed light on games as experiential content. The study analyzed gaming acts based on Park Sang-woo (2009) and assumed that gaming acts would change greatly according to the degree of real space intervening in game space; thus, examining changes to the gaming acts of games in two aspects of realizing virtual space from imaginations in game space and reproducing virtual space in real space.

This year, global IT companies such as Google, Apple, and Facebook launched a mobile augmented reality platform. Existing augmented reality technology required a special device such as AR glass or tango phone, but now it will be easy to experience augmented reality in general Android phone and iPhone. The mobile augmented reality game market, which has been attracting interest since the Pokemon game, is expected to become more active. In this article, we introduce augmented reality platforms technology for mobile augmented reality game and mobile augmented reality games including ETRI prototype centered on user interface.
