Abstract

As a result of the recent development and dissemination of HMD equipment, there has been an increase in the development of virtual reality contents. However most of these developments do not take differences of users' cognitive abilities and users' ability to immerse in and connect to these contents into consideration. In this study, we investigated the effects of visual factors of contents by conducting literature reviews, and conducted research on the correlation between visual factors and Virtual reality presence. While color and spatial factors had significant positive effects on content recognition and sense of reality, motion perception factors caused cognitive dissonance, which negatively effects the accurate recognition of contents. We were able to find that accurate recognition of virtual reality contents have a great impact on users' sense of reality.

최근 HMD 장비의 발전 및 보급 확대와 함께 가상현실 콘텐츠의 개발도 늘어나고 있으나 개발되는 대부분의 가상 현실 콘텐츠는 사용자의 인지 능력 차이를 참작하지 않고 개발되고 있고, 가상현실 콘텐츠를 이용하는 이용자에 따라 느끼는 몰입감이나 현실감이 크게 차이 나고 있다. 본 연구에서는 문헌연구를 토대로 가상현실기반 콘텐츠 제작시 내용 인지에 미치는 시각적 요인들을 도출해 내고, 실험을 통해 이러한 요인들이 콘텐츠 내용 인지에 미치는 영향과 실재감과의 상관 관계에 관하여 연구를 진행하였다. 연구 결과, 시각요인 중 색상지각과 공간지각요인은 콘텐츠 인식 및 실재감에 유의미한 영향을 미치는 것으로 나타났으며, 운동지각 요인은 인지부조화로 멀미를 일으키고 콘텐츠의 정확한 인식에도 부정적 영향을 미친다는 것을 알 수 있었다. 또한 VR 콘텐츠의 인지는 실재감에 크게 영향을 미치는 것을 알 수 있었다.
