Evaluation of immersive virtual environments displaying various areas

Abstract

There is widespread interest in wide display screens such as CAVE, which have displays with a field of view of over 180 degrees, covering the whole field of vision. The design of the display screen is essential in achieving a very accurate sense of reality in virtual environments(VEs) because an image can provide users with a wealth of information. The response of humans to the visual stimulus in VEs is percieved to be one of the more promising potential estimation methods to measure the presence sense and immersion of a VE system. This study aims to analyze the body sway of the subjects, caused by the vection, in a VE system to verify the essential area and proper size of the display necessary for the efficient performance of presence sense when conditions like display areas are changed. It has been demonstrated that over FOV100 and bottom side projections play an important role in making the sense of presence in VE even at the combination display conditions. Also, the body sway has a close relationship with the subjective immersion status of subjects by the self-report method.
