Abstract : The scope of this study is the evaluation of the role played by simple orientation cues (visual and acoustic) within a virtual environment (VE). The main efforts during this project consisted of designing and conducting target detection tests in a VE with and without visual and acoustic orientation cues. In addition, a system based on the SRI dual Purkinje image Eyetracker was set up to study eye movements induced by displaying moving target images at various image update rates, as occurs in VEs. This report describes and analyzes experimental data on both visual and acoustic cues of orientation, as well as data on image update rates and related eye movements.
