초록
본 연구는 몰입형 가상현실에 존재하는 다수의 HMD 사용자들에게 보다 향상된 현존감과 만족스러운 경험을 제공하기 위하여 협업기반 다수 사용자 상호작용을 제안한다. 제안하는 다수 사용자 상호작용의 핵심은 가상현실 환경에 존재하는 HMD 사용자가 각자 구분된 역할과 행동을 기반으로 소통과 협업을 통해 상호작용할 수 있는 방향을 제시하는 것이다. 가상협업환 경에 존재하는 사용자 각각은 손을 활용하여 가상 환경 또는 가상의 객체와 직접적으로 상호작용하는 기본 구조를 바탕으로 사용자간 소통과 협업을 통해 공동의 목표를 수행해 갈 수 있는 방식(동기화, 의사소통)을 함께 설계한다. 그런 다음 제안하는 다수 사용자 상호작용을 통해 향상된 현존감과 만족하는 경험을 제공하는지를 검증하기 위하여 소통과 협업을 고려한 아케이드 장르의 가상현실 어플리케이션을 제작한다. 그리고 참가자들을 대상으로 한 설문 실험을 진행한다. 이러한 과정들을 통해 제안한 몰입형 가상협업환경에서의 상호작용이 사용자 모두에게 만족하는 현존감과 경험을 제공함을 확인한다.
Abstract
This study proposes collaboration based multi-user interaction to provide improved presence and satisfying experience to multiple HMD users in immersive virtual reality. The core of the proposed multi-user interaction is to present the direction in which HMD users in virtual reality environment can interact through communication and collaboration with each other based on their separate roles and behaviors. Each user in the virtual collaborative environment uses a hand to interact with a virtual environment or virtual objects. Based on the basic structure, this study designs methods (synchronization and communication) that can be achieved a common goal together through communication and collaboration. Then, this study creates a virtual reality application of arcade genre that considers communication and collaboration in order to verify whether the proposed multi-user interaction provides improved presence and satisfaction experience. And, the survey experiments are conducted for participants. Through these processes, it is confirmed that the interaction in the proposed immersive virtual collaborative environments provide the presence and experience that is satisfactory to all users.
