The viewpoint of a digital game is a prime factor that determines user immersion, and first-person viewpoint is known to produce greatest immersion. However, most games adopt third-person viewpoint rather than first-person viewpoint. This study analyzed the reason for the preference of third-person viewpoint. First, six viewpoints were defined by combining three viewpoints (first-, third-person, omniscient viewpoints) and two distances (proximal, distal) between camera and game character. Then 100 games which received high ratings during the past 10 years were sampled, and the frequencies of viewpoint choices and genres were analyzed. Overall, the results showed that games have strong preference for third-person viewpoint. However, preferred viewpoints differed depending on genres, for example, most shooting games used first-person, proximal viewpoint. This result could have arisen because both characteristics of a game and field of view have influenced choice of viewpoint. That is, many games adopt third-person viewpoint because developers consider not only user immersion but also scene visibility.

The purpose of this study is to investigate the limitations of virtual space game contents staying in the first-person viewpoint in the field of digital games with various genres through precedent researches and case studies, and to investigate the differences of immersion, presence, and fun based on the user interfaces, such as the viewpoints (first-person, third-person) and haptic feedback. The experimental results show that when the game is the first-person with the haptic feedback, the immersion, presence, and fun increase. However, the interaction effect between the virtual space environment and the game viewpoint was not found. As a result, it is appropriate to use the haptic feedback and the first-person viewpoint in the virtual reality games, but the fact that the game viewpoints and the virtual space environment are not huge relevant, and the third-person viewpoint is more popular than first-person viewpoint game, therefore the possibility of a third-person viewpoint game would be suggested.

This paper proposes three schemes of one-hand control that can be used in the First-Person Viewpoint mobile games and evaluates them. Displaying virtual controllers on the screen, the existing mobile games use schema that allows users use both hands. In the First-Person Viewpoint mobile games, however, one-hand control is possible because smaller number of functions for viewpoint movement is required. This research proposes three one-hand control schemes for First-Person Viewpoint movement and rotation, and evaluates them using AHP. The experiment results prove that one-hand control schemes are more useful than both-hands control schemes for the mobile game users.

본 논문에서는 이러한 방식에서 탈피한, 3D 그래픽을 이용한 1인칭 미니 회피게임을 제작하는 방법에 대해 제안한다. 기존의 3인칭 시점에 상하좌우 네 방향으로만 움직이는 방식을 벗어나, 시점을 1인칭으로 변환하고 FPS와 같은 시점과 이동방식을 제공하며, 기존의 2D게임에서 사용되던 축이 고정된 오브젝트의 충돌인 AABB(Axis Aligned Bounding Box)가 아닌 축이 수시로 변하는 OBB(Oriented Bounding Box) 방식을 사용함으로 써, 3D 그래픽에서도 2D 그래픽에서처럼 정교한 충돌 검출 기능이 가능하도록 제작한다.

This study examines the characteristics of screen image of 3D first-person shooting games and the newly created subjectivity by that image. 3D first-person shooting games create immersion by remediating the visual experience in the real world. The construction of subjective perspectives and comparatively clear interface are the important features of 3D first-person shooting games. The subjectivity created by this games' image is different from the subjectivity constructed by suture of film. Gamers have the dominant position of the subject of looking, gaming and narrating, but the narrating position is never permanent nor stable. Because the position has the limited sight of first-person, not the comprehensive sight of third-person.

This article focuses on perspectives of game in terms of interactivity between game texts and players. There are many points of view which have been discussed, such as first person point of view, third person point of view, top-down point of view, side-view point of view, quarter-view point of view, and isometric point of view, but they are too insufficient to fully explain the perspectives of game from the viewpoint of the interactivity. This paper examines the function of player and game manufacturer as implied authors on interactive point of view, and discusses the perspectives of game through a sense of distance between players as implied author and player characters.

가상현실(Virtual Reality, VR), 증강현실(Augmented Reality, AR), 혼합현실(Mixed Reality, MR) 분야에 유용한 인간 컴퓨터 인터페이스 기술은 필수적이다. 특히 휴먼 손동작 인식 기술은 직관적인 상호작용을 가능하게 하여, 다양한 분야에서 편리한 컨트롤러로 사용할 수 있다. 본 연구에서는 뎁스 영상 기반의 1 인칭 시점 손동작 인식을 위하여 손동작 데이터베이스 생성 시스템을 구축하여, 손동작 인식기 학습에 필요한 1 인칭(Egocentric View Point) 데이터베이스를 촬영하여 제작한다. 그리고 모바일 Head Mounted Device(HMD) VR 을 위한 뎁스 영상 기반 1 인칭 시점 손동작 인식(Hand Pose Recognition, HPR) 딥러닝 Deep Residual Network 를 구현한다. 최종적으로, 안드로이드 모바일 디바이스에 학습된 Residual Network Regressor 를 이식하고 모바일 VR 에 실시간 손동작 인식 시스템을 구동하여, 모바일 VR 상 실시간 3D 손동작 인식을 가상 물체와의 상호작용을 통하여 확인 한다.

This study examines the potentials of realistic controller and point-of-view to affect users' arousal, valence, identification and engagement. While media researchers have advocated the role of realistic controller and point-of-view as a possible contributor to psychological reactions of playing video game, this claim is based on a relatively small number of empirical studies. Collegiate subjects took part in an experimental investigation manipulation the level of controller realism(gamepad vs. steering wheel) and point-of-view(first person vs. third person). Results of the study showed the influence of controller realism and point-of-view on arousal, identification and engagement, and the implication of the findings are discussed.

Despite a rapid market growth in VR, cyber sickness has become the most serious problem in terms of user experience. The aim of this study is to verify whether there are differences in user's perception of cyber sickness by the point-of-view and the movement in VR contents. An experimental testing of game playing with VR headset was conducted on the effects of two conditions: first-person and third-person views in the point-of-view condition, and yaw - pitch rotations in the head movement condition. The results showed that cyber sickness worsened in the first-person point-of-view and in the yaw rotation movement. Point-of-view and movement had main effects on the cyber sickness, but an interaction effect between point-of-view and movement was not found. Based on the findings, along with reducing VR sickness, we proposed practical implications for VR contents planning for building balanced VR user experience. Positive VR experience can be reinforced through visual design, multi-modal interface design, and experience marketing for the optimal level of contents immersion. A future research was suggested on the roll rotation for diverse content genre development.

본 논문에서는 1인칭 시점 VR 게임 콘텐츠를 개발하였고, 멀티플레이를 구현할 때, 가상현실 세계에서 플레이어들끼리 대면했을 때 서로의 캐릭터가 폰 콘트롤러라는 이름의 팔만 보이는 외형을 띠고 있다. 게임에서 시각적인 부분을 간과할 수 없기에 멀티플레이 시 서로의 캐릭터가 보일 수 있도록 새로운 방법을 제안하였다. 3인칭 캐릭터를 이용해서 만든 캐릭터는 인간과 같은 외형의 스켈레톤을 사용하면 원하는 캐릭터를 사용할 수 있다. 3인칭 캐릭터의 양팔의 트랜스폼 값을 언리얼엔진4의 라이브러리인 패브릭 노드를 이용하여 모션 콘트롤러와 매핑을 시키는 방식으로 접근하였다. 이를 통해 좀더 플레이시 실감이 가능한 게임 제어기법을 적용할 수 있다.
