Abstract:
This study investigated humans ability to control simulated ego-rotations from optic flow. The stimuli consisted of limited lifetime dots on a dark background. In a within-subject design, performance was tested using a curved projection screen (FOV 86°×63°), a HMD (40°×30°), and blinders (40°×30°) that restricted the FOV on the screen. Participants typically undershot intended turn angles. Performance was best with the screen (gain factor 0.77) and worst with the HMD (gain 0.57). A significant difference between blinders (gain 0.73) and HMD indicates that different display devices can influence ego-motion perception differentially, even if the physical FOVs are equal.
