Abstract

An adaptive autostereoscopic display system (10) provides an apparatus for conditioning the psychological state, physiological state, or behavior of a subject (12) by displaying a stereoscopic virtual image at a left viewing pupil (14l) and a right viewing pupil (14r). A first set of images (100) is displayed and physiological response measurements are obtained from the subject (12). Based on the response of the subject (12) a personalized image response profile is obtained. Then, in order to condition the psychological state, physiological state, or behavior of the subject (12), a second set of images (102), based on the personalized image response profile is displayed.
