The background fort this study is related to the concept of modern time and space which has been extended from physical space to virtual space in the present times witnessing the advent of the Fourth Industrial Revolution. Based on visual tactility and illusion in virtual reality, we intended to present the possibility of the interactions as realistic as the interactions occurring in reality. Regarding the scope of this study, we analyzed the relationship between illusion in game space and immersion in interactions based on the games used frequently among current virtual reality contents. The results of the study showed that the interactions in virtual reality occurred within the space converging the time and space and that the illusion of digital images had realistic position of reality without original. Research which investigates the interaction in virtual space and media projection method for real space and virtual space will provide useful basis for promoting technological development based on novel methods differentiated from existing image grammar and for identifying the content utilization methods.

As augmented reality technology has developed, various augmented reality contents can be seen in real life, and the performance of mobile device is improved, so augmented reality technology can be used even without special device. As a result, a training system, guidance system and a museum art guide system based on augmented reality technology are emerging, and interest in augmented reality is also increasing. However, the existing guidance systems using a single mobile device have limitations in terms of the user experience (UX) because the camera of the device limits the field of view or the two hands are not free and the user input is difficult. In this paper, we compare augmented reality based guidance systems for Rubik's Cube using tablet and HMD to improve the constraint of user experience of such a single mobile device, and find elements that positively improve user experience. After that, we evaluate whether the user experience is actually improved through the user experience comparison test and the questionnaire.

Objective: The aim of this study is to propose the contactless gesture-based interface on smart mobile devices for especially rhythm action games. Background: Most existing approaches about interactions of smart mobile games are tab on the touch screen. However that way is such undesirable for someone or for sometimes, because of the disabled person, or the inconvenience that users need to touch/tab specific devices. Moreover more importantly, new interaction can derive new possibilities from stranded game genre. Method: In this paper, I present a smart mobile game with contactless gesture-based interaction and the interfaces using computer vision technology. Discovering the gestures which are easy to recognize and research of interaction system that fits to game on smart mobile device are conducted as previous studies. A combination between augmented reality technique and contactless gesture interaction is also tried. Results: The rhythm game allows a user to interact with smart mobile devices using hand gestures, without touching or tabbing the screen. Moreover users can feel fun in the game as other games. Conclusion: Evaluation results show that users make low failure numbers, and the game is able to recognize gestures with quite high precision in real time. Therefore the contactless gesture-based interaction has potentials to smart mobile game. Application: The results are applied to the commercial game application.

The increasing interest in digital leisure with virtual reality has led to the emergence of digital based urban theme park. Since there were some game type based digital theme parks, which ended up failed in Korea, we analyzed game and space factors for game based digital theme park by drawing upon Maslow's need theory and the hero's journey by Joseph Campbell. We anticipate our research for analysis of game based theme park provides important groundwork on designing various digital urban theme park.

In this paper, we will discuss planning and production of VR contents for effective racing drone steering training. In the real world, direct racing drone training training is obviously a space and economic limit. We propose through the production of VR-based drone infiltration action game as a solution to these limitations and try to improve effective drone handling ability. Especially, we designed the virtual reality contents in a similar environment by using the similarity of FPV goggles and HMD based VR, and designed virtual drones, maps and obstacles considering the characteristics of the structures used in racing drone and drone racing. Also, we tried to increase the user's immersion and presence by increasing difficulty level of obstacles.

In this paper, we propose a game type cognitive rehabilitation system using marker-based augmented reality system for intelligence development of user. Existing cognitive rehabilitation with the help of others, or a keyboard or mouse operation required to relieve the discomfort, the marker card only control it led and is advanced the method which it applied. As a result, obtained through the camera calibration for image processing, and a Augmented Reality as well as mark detection. In this paper we presented a complete rotation of the model after checking through the whole form, through a combination of multiple markers by completing the interactive objects proceed with the rehabilitation process in a manner required by the target of interest to human rehabilitation and treatment.

Purpose : The purpose of this study is to evaluate the effects of virtual reality based exercise program on gross motor function and balance of children with spastic cerebral palsy. Method : Subjects of this study, among the children who received the diagnosis spastic cerebral palsy, for children total of 8 people have agreed to research. Experimental group 4 people, control group 4 people, was a total of 8 people. Group-specific arbitration method, was applied to Nintendo Wii Fit game (experimental group) and exercise program (control group). Each training courses 30 minutes for 4 weeks, examined the changes in Gross Motor Function Measure(GMFM) and Pediatrics Balance Scale(PBS) ability to examine a total of 4-week course effectively. The intervention were compared by measuring before and after. Result : There were significant improvements in the subscales of the gross motor function and balance test of those who practiced with the Nintendo Wii Fit game, while the control group showed no significant changes. Conclusion : Therefore, the virtual based on exercise is effective in improvement of to improve the gross motor function and balance in children with spastic cerebral palsy.

Recently, virtual reality contents are being experimented and introduced in various fields such as game, education, medical, exhibition, movie, SNS. However, research on virtual reality is mainly focused on industrial and technological perspectives, so contents-centric or contents-oriented research is on virtual reality is very rare. In order to prepare for the future of virtual reality properly, content-oriented research is very much needed. The purpose of this study is to investigate the types, characteristics, and possibilities of virtual reality contents applied to theme parks. For this purpose, we tried to classify the contents type of virtual reality based theme park. The criteria of type classification are divided into 'fixed type', 'continuous moving type', and 'segmented moving type' according to the player's position movement possibility and movement type, here we combine the senses such as tactile, taste, smell, balance etc.

최근 가상현실을 활용한 게임콘텐츠들이 많이 제작되고 있다. 그러나 킬러콘텐츠가 부족한 상황이며 가상현실 게임을 즐기기 위해 사용하는 HMD(Head Mounted Display)는 멀미감 때문에 장시간 사용하기 힘들다. 본 연구에서는 멀미감을 최소화할 수 있는 퍼즐과 요즈음 오프라인에서 인기가 있는 방탕출 게임을 동시에 즐길 수 있는 콘텐츠를 제안한다. 특히, 개발한 콘텐츠는 Unreal Engine을 사용함으로서 게임에 현실성을 더욱 가미할 수 있었고 남녀노소 누구나 즐길 수 있는 범용적인 콘텐츠이다. Unreal Engine을 활용한 게임이 별로 많지 않아 본 콘텐츠는 향후 Unreal Engine를 활용한 게임을 제작하는데 도움이 될것이라 사료된다.
