Abstract

The purpose of this study was to examine the effects of display on time on tasks and virtual presence in the immersive virtual reality. Head mounted display (HMD) and monitor conditions were compared when the participants were asked to complete navigation tasks in a virtual classroom. Time on tasks and virtual presence were measured. Three factors of the virtual presence were applied as dependent variables such as 1) spatial presence, 2) involvement, and 3) realness. The results showed that HMD condition took longer time to finish tasks than monitor conditions. HMD condition showed significantly higher perception from all of the virtual presence factors. Interestingly, there was a significant interaction effect between the display conditions and presence factors. The relationship between display types and virtual presence factors were discussed for future study.

이 연구는 가상현실 환경에서 디스플레이의 종류가 가상실재감에 미치는 영향을 검증하기 위하여, 착용형 디스플레이(head mounted display)와 모니터조건이 내비게이션 과제수행시의 가상실재감에 미치는 영향을 분석한 것이다. 가상 실재감을 구성하는 하위요인으로 공간실재감(spatial presence), 몰입감(involvement), 사실성(realness)을 구성했다. 과제수행시간과 가상실재감에 대한 지각점수를 종속변수로 해서 디스플레이 조건에 의한 차이를 분석했다. 분석결과에 따르면 모니터조건과 비교했을 때 HMD조건에서 전반적으로 과제수행시간이 길었다. 이런 결과가 나타난 것은 HMD에서의 몰입감이 높기 때문에 오히려 주변 사물에 대한 탐색활동이 더 늘어난 것으로 보인다. 가상실재감에서는 HMD 조건이 탁월하게 높았으며, 같은 HMD조건에서는 특히 공간실재감과 몰입감이 사실성 보다 모두 높게 지각되었다. 이 연구를 통해서 HMD와 모니터 조건에 따라서 가상실재감의 하위요인에 미치는 수준이 다르다는 것을 확인할 수 있었다.
