Abstract and Keywords

This chapter analyzes the level of realism (LoR) in virtual environments (VEs), particularly the senses of touch, smell, and taste. It explains that it is currently not possible to simulate feel, smell, and touch with full physical accuracy in VEs but a real-virtuality system can provide perceptual realism by delivering many multisensory stimuli, which is achieved by selectively delivering real-world stimuli and by exploiting the fact that the human perceptual system is simply not capable of attending to all stimuli at the highest precision all the time. It argues that the success of VEs require a thorough understanding of the LoR required in order to achieve the necessary perceptual equivalence between the real-world scenario and its virtual simulation.

Keywords: level of realism, virtual environments, touch, smell, taste, real-virtuality system, perceptual realism, real-world stimuli, perceptual equivalence
