Influence of Binocular Disparity in Depth Perception Mechanisms in Virtual Environments
In this chapter, an experimental study is presented for evaluating the importance of binocular disparity in depth perception within a Virtual Environment (VE), which is assumed to be critical in many manipulation tasks. In this research work, two assumptions are made: Size cues strongly contaminate depth perception mechanisms and binocular disparity optimizes depth perception for manipulation tasks in VE. The results outline size cues as possible cause of depth perception degradation and binocular disparity as an important factor in depth perception, whose influence is altered by the position within a VE.
This study has been partially funded by the Spanish Ministry of Education and Sciences (Project TIN2006-15202-C03-02) and the council of Andalusia (Group PAI TIC-171). Special thanks to Carmen Garcia Berdonés for her comments.
