A system includes a tracker, an autostereoscopic display, and at least one processor. The at least one processor is configured to track an eye position of a given eye of a given user relative to an image plane of the autostereoscopic display, using the tracker. The at least one processor is further configured to detect when the eye position of given eye is no longer trackable by the tracker. When the eye position is no longer trackable, the at least one processor is configured to generate or retrieve an image for display to the given eye, increment a tracking counter, map a value of the tracking counter to a transition level, and perform at least one of modifying pixel intensity values of the image based on the transition level to fade out the image, or interpolating a virtual depth in the image based on transition level, and display the image.

Reducing visual jolts during tracking loss and gain in autostereoscopic displays

An autostereoscopic display includes a pixel array and a multiscopic optical element. The pixel array includes a plurality of pixel rows, each of the plurality of pixel rows being aligned along an X-axis of the autostereoscopic display. The multiscopic optical element comprises a plurality of multiscopic cells () and lies on an XY plane of the autostereoscopic display. Each of the plurality of multiscopic cells has a longitudinal axis (P-Q) aligned along a Y-axis of the autostereoscopic display. In a given set of consecutive pixel rows, a starting position of a given pixel row is horizontally offset relative to a starting position of a preceding pixel row. The horizontal offset is represented along the X-axis.
