Advances in IT technologies are developing VR content technologies that provide five senses information to users and interact with them. These VR content technologies are widely used by users not only for time and space limitations but also for providing immersion experiences. VR contents are contents that allow users to experience images that are played on the screen through five senses such as augmented reality, virtual reality, and holograms as well as visuals. VR games are also becoming more diverse in interfaces for the interaction of users with VR games. This study recognized the importance of the interface and analyzed the impact of the application characteristics of VR game UI on user experience and satisfaction from the user perspective. Research shows that VR game UI interacts with user experience and satisfaction. This appears to affect user experience based on how well people using VR game UI can understand and utilize the characteristics and functions of UI.

In this study, the hardcore game user verified the manipulation delay that occurred during VR game play because of the experienced game. Based on the HCI - based research approach, we created a 2D, 3D, and VR prototype game with user manipulation cycle hypothesis. Based on this, 121 users were experimented with 2D, 3D, VR format user interface. The average user manipulation period extracted by the experiment was compared with the independent sample T test. Based on the test results give the average time difference between the user's operation of the 2D VR format has been verified. User operation period of the average time difference in 3D VR format proved the null hypothesis of no significant difference has been adopted.

VR(virtual reality, 가상 현실) 환경이 대중화 되면서, VR 환경 하에서 사용자가 반력(force feedback)을 느끼게 하는 방법들에 대한 연구가 활발해 지고 있다. 이러한 반력의 사용에 있어, 반력을 지원하는 하드웨어, 소프트웨어들이 필수적이고, 기존의 탁상형 고정식인 반력 게임컨트롤러 뿐만 아니라, 게임 플레이어가 보다 향상된 체감효과를 통해 현실감을 경험할 수 있도록 다양한 햅틱 장치를 필요로 한다. 본 연구에서는 신체에 착용하여 체감을 느낄 수 있도록 특별 제작된 (custom) 햅틱 수트 (haptic suit)를 다룬다. 이를 위한 게임 인터페이스를 제시하여, 게임 컨텐츠에 실재감을 부여할 수 있는 반력을 편집하고, 재생할 수 있는 효과 생성기를 제시한다.

In order to use the VR HMD, operation through separate controllers in both hands is required. Methods for text input in VR include a method of selecting virtual keyboard keys on the screen one by one using a controller, a method of inputting through a keyboard that is a resource of a computer by connecting a computer and VR, or a method of inputting through a keyboard that is a resource of a computer by purchasing a wireless keyboard in VR and wireless keyboard connection method. As such, the text input method in current VR equipment causes inconvenience and additional costs to users. For these reasons, most of the VR-related contents are limited to simple functions such as games or viewers, and there is a risk that VR equipment will be recognized as a simple game machine. Therefore, in this study, a multi-input interface using hand tracking provided by the Oculus Quest2 device is designed and partially implemented. Through this, it is expected that various tasks such as document work and business processing as well as games can be conveniently used using VR equipment.

In recent years, various virtual reality games are becoming commercialized. A variety of large 3D online games popular with users has begun to transform into VR games. < the Elder Scrolls V: skyrim VR > as a derivative of large-scale 3D online games < the Elder Scrolls V: skyrim special edition >, Since its launch on the steam game platform in April 2018, because of its original UI design, maximizes the user's immersive experience and firmly maintains the leading position of VR games. Although the visual similarities between < the Elder Scrolls V: Skylim VR > and < the Elder Scrolls V: Skylim Special Edition > are high, but the visual elements in the UI are quite different. This paper studies characters, scenes, operating interfaces, colors and fonts five visual UI elements that enhance the immersion in game. It provided a unique interface design reference to immersive experience of new VR games in the future.

With the development of game technology, the realistic game graphics, interface technology, and various content services with immersion are being required in the content area. NUI has been developed through CLI and GUI. Unlike the conventional methods, it is an interface that could be the intuitive and realistic interface for human as a natural action realized. we propose a boxing simulation game using leap motion of it. Providing a realistic 3D experimental environment through VR headsets game, we also propose a method that can be calculated the scores if the user-controlled interface (fist) could be to punch the target (sandbag) of the internal in accordance with changes of the angle of target impact with the physical characteristics.

본 논문에서는 가상환경에서의 바둑 게임을 위하여 CyberGlove와 트랙킹 장비를 이용한 사용자 인터페이스를 구축하고 이의 사용성을 평가하였다. 먼저 바둑 게임을 위한 3차원 객체들을 생성한 후, WorldTookit을 이용하여 가상환경을 구축하였다. 그리고 트래킹 리시버가 부착된 CyberGlove를 끼고 바둑함으로부터 "바둑알 집기"와 바둑판 위의 화점에 "바둑알 두기"를 통해 가상환경에 익숙치 않은 사용자들을 대상으로 인터페이스의 사용성을 평가하였다. 실험 결과 현실 세계와 같이 손과 손가락을 움직여 바둑을 두는데 매우 흥미로와 했고, 사용자의 2가지 뷰에 따라 실험한 결과 직교 top 뷰에서의 정확도가 대각 원근 뷰 보다 높게 나타났다. 또한 주변 화점에 바둑알을 둘때의 정확도가 현저히 저하됨을 알 수 있었다. 장기간 사용시 불편함 호소 등 해결해야할 문제가 있음에도 불구하고 가상현실 인터페이스는 보다 몰입적이고 현실감 있는 게임을 위해 필요한 요소임을 확인할 수 있었다.

VR(Virtual Reality), which has drawn attention as a major area in ICT, is currently being used in various fields, including medical care, movies and architecture. Although VR technology is used in various fields, contents are mainly developed by creators where needs of users are easily left out of consideration leading to failure in forming a consensus between UI(User Interface) and UX(user experience). To identify the consumer preference and attribute level of VR game content, which is responsible for the largest proportion of VR contents, this study was designed to examine the consumers' preference properties of VR game contents through a Conjoint Analysis and derive the relative importance and weightings of each group. The study collected 166 questionnaires over a total of three months from May to July 2019, 150 of which were completed (90.4%). Statistic analysis was conducted using SPSS Ver. 25.0. The results of the study showed that the genre of the game (42.6%), number of players (24.0%), price for payment (20.3%) and game planning (13.1%) were important attributes in choosing VR games. The optimal mix of attributes was derived with new games, RPGs, multi-play and medium price (22,000 KRW). Before mentioning technology in the expectations of users who use VR game content, which is the most preferred among VR contents, this study recognized the need to have a fun and new experience through VR game content. Therefore, it is expected that this will serve as a reference for consumer behavior of VR game contents and research on VR game contents development.

The purpose of this paper is to identify the significance of heterogeneity in multi-player VR games. Heterogeneity is a concept of multi-player mode that a game uses the immersive VR and non-immersive system at the same time. As immersive VR device has become more commercial, multi-player VR games try to use heterogeneity strategically. is the best example to explain a new phenomenon, so this paper analyses by using a revised and reinforced MDA framework. As a result, we can find heterogeneity concept not only in the separation of player's interface, but also in the division of play patterns and experiences within a game itself.

Good reviews that Half-Life: Alyx received created a turning point for the vitalization of the VR market with an uncertain future due to the absence of a revenue model together with the increased sales of VR equipment. Based on previous studies, this study categorized the characteristics of VR games according to graphs, first-person system, interface, controller, interaction technology, sound and stories. The analysis results show that the seven elements corresponded with "interactions" and "virtual images," which represent the completion level of games as part of VR components, and were connected to one another, which led to the proposal of an upper-rank concept "presence" to put them together. "Immersiveness," which represents users' emotions as part of VR components, was analyzed with the immersion theory to assign tasks of proper difficulty level for users' abilities. In the research process, the Delphi technique and FGI were administered to a panel of 15 experts to ensure objectivity. Finally, "presence" and "immersiveness" are characteristics in proportion to each other and can be valid concepts in future analysis of VR games as well as Half-Life: Alyx, which led to the proposal a new concept framework called 'presence effects' by combining the two words.
