초록

본 연구는 비대칭 가상현실 환경에 존재하는 HMD 사용자와 Non-HMD 사용자 모두에게 향상된 현존감을 제공하기 위하여 사용자의 체험 환경에 최적화된 몰입형 상호작용을 제안한다. 제안하는 몰입형 상호작용의 핵심은 HMD 사용자와 Non-HMD 사용자 사이의 비대칭 환경의 차이를 구분하여 사용자에게 최적화된 상호작용을 제시하는 것이다. 그리고 사용자 각각에게 주어지는 비대칭 가상현실 환경에서 향상된 몰입을 제공하여 현존감을 높이기 위하여 HMD 사용자에게는 공간의 몰입을 향상시키는 걷기 상호작용을, Non-HMD 사용자에게는 직접적인 조작을 통해 상황을 전체적으로 이해하고 관리함으로써 몰입을 향상시키는 손 기반 인터페이스를 설계한다. 마지막으로 몰입형 상호작용을 통해 모든 사용자가 향상된 현존감을 제공받으면서 동시에 각각의 체험에 환경에 특화된 경험을 하였음을 설문실험을 통해 검증한다. 이러한 과정들을 통하여 제안한 상호작용이 비대칭 가상현실에서 Non-HMD 사용자도 보조자가 아닌 참가자로써 HMD 사용자와 함께 몰입할 수 있음을 확인한다.

Abstract

This study proposes an immersive interaction optimized for the user’s experience environment to provide an improved presence for both HMD and Non-HMD users in the asymmetric virtual reality (VR) environment. The core of the proposed immersive interaction is to distinguish the differences of the asymmetric environment between the HMD and Non-HMD users and present the optimized interaction to the user. And, in order to increase the presence by providing improved immersion in the asymmetric virtual reality environment given to each user, we design the walking interaction to improve the immersion of space for the HMD users, a hand-based interface that improves immersion by fully understanding and managing the situation through direct control. Finally, through the experiment using questionnaire, it is verified that the immersive interaction provides all users with an enhanced presence and specialized experience in each environment experience. Through these processes, we confirmed that the Non-HMD user can be immersed in an asymmetric virtual reality using by proposed interaction as participant rather than assistant with HMD user.
