Audio, visual, and audio-visual egocentric distance perception by moving participants in virtual environments
A study on audio, visual, and audio-visual egocentric distance perception by moving participants in virtual environments is presented. Audio-visual rendering is provided using tracked passive visual stereoscopy and acoustic wave eld synthesis (WFS). Distances are estimated using indirect blind-walking (triangulation) under each rendering condition. Experimental results show that distances perce...
متن کاملAudio, visual, and audio-visual egocentric distance perception in virtual environments
Previous studies have shown that in real environments, distances are visually correctly estimated. In visual (V) virtual environments (VEs), distances are systematically underestimated. In audio (A) real and virtual environments, near distances (< 2m) are overestimated whereas far distances (>2 m) are underestimated. However, little is known regarding combined A and V interactions on the egocen...
متن کاملAudio-Visual Perception in Interactive Virtual Environments
Interactive virtual environments (VEs) are gaining more and more fidelity. Their high quality stimuli undoubtedly increase the feeling of presence and immersion as “being in the world”, but maybe they also affect user’s performance on specific tasks. Vision and spatial hearing are the main contributors of our perception. Sight dominates clearly and has been in the focus of research for a long t...
متن کاملRunning head : Audio - visual speech perception is special Audio - visual speech perception is special
In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to p...
متن کاملLyceum: Audio Visual Conferencing in Distance Education
Lyceum is an audio and visual conferencing system for the Internet. Using Lyceum participants can exchange audio messages and share visual applications in real-time. The system is under development at the Open University to be deployed on distance learning courses. This document describes the system and its architecture.
