Abstract
Autostereoscopic display. The display includes an array of elements from which light emanates, the elements being rotatable about two orthogonal axes by microcontrollers. An eye tracker is provided for determining the location in three dimensions of at least one eye viewing the array. The microcontrollers, using information from the eye tracker, rotate the elements to mimic a concave surface to deliver light to the eye. It is preferred that the elements are mirrors and the display further includes a projector for projecting an image on the array for reflection to the eye. The elements themselves may include structure for generating light rather than reflecting light.
