Abstract :
Individuals with schizophrenia (SZ) perceive various visual stimuli differently than healthy controls. This is especially true of the “hollow-face illusion.” We have created a virtual rendering system that exploits this well-known fact. We also explain the addition of a head-tracking feature that provides a more realistic spatio-temporal interaction for our virtual-reality apparatus. Our system is capable of quantifying the amount of time a person perceives the illusion and affords a comparison between SZ patients and controls, thus offering a diagnostic tool for SZ.
