Believable virtual environment : sensory and perceptual believability

Abstract

Believability is a term to measure a level of realism in the interactive virtual environment. In this paper, the believability is described in two layered manner. The elementary layer consists of fundamental aspect of the system including immersion, presentation and interaction. These aspects are discussed in uniand multi-sensory channel including visual, auditory and haptic. In a higher layer, emotion and personality is one of the main issues to provoke believability. The effects of elements are described in perception and generation of motions.
