Abstract

An autostereoscopic image display apparatus (10) that adapts to sensed feedback data about an observer (12) in order to conform its operation to adapt to the position and intraocular dimensions of the observer. The apparatus (10) uses ball lens projection optics to provide wide field-of-view pupil imaging, providing separate left- and right-eye images to the left and right eye pupils (14l,14r) of the observer (12), respectively. The apparatus (10) compensates for positional variables such as variable interocular distance and variable observer distance from projection optics. At least one observer feedback sensor (52) is disposed to provide feedback data about the observer (12). The feedback data can be used by a control logic processor (50) that, based on the data, adjusts left- and right viewing pupil forming apparatus (36l,36r). The control logic processor (50), based on sensed feedback data, may also vary image content or provide other stimuli such as smell, movement, and sound.
