Claim:
1. A method for displaying autostereoscopic 3D images, the method comprising: providing a display device; receiving eye-location data indicative of a first and second set of eye-locations relative to the display device, wherein the first set of eye-locations comprises a first left-eye location and a first right-eye location associated with a first viewer and the second set of eye-locations comprises a second left-eye location and a second right-eye location associated with a second viewer, the received eye-location data further indicative of movement of at least one of the first or second sets of eye-locations relative to the display device; sequentially outputting, from the display device, light rays representing a left-eye view of the 3D images and light rays representing a right-eye view of the 3D images for the first and second viewers; based at least in part on the received eye-location data, using an active solid-state optical deflector (i) to deflect the output light rays representing the left-eye view towards the first left-eye location and the second left-eye location and (ii) to deflect the output light rays representing the right-eye view towards the first right-eye location and the second right-eye location; estimating a refresh time corresponding to when the display device will refresh the displayed 3D images; estimating future eye-locations based at least in part on the indicated movement characteristics of at least one of the first or second set of eye-locations, wherein the estimated future eye-locations correspond with an expected eye-location of at least one of the first or second eye-locations at the estimated refresh time; and deflecting the output light rays towards the estimated future eye-locations at the estimated refresh time; wherein the light rays representing the first viewer right-eye and left-eye views are deflected towards the first set of eye-locations such that each light ray is directed to a focused spot smaller than an eye of the first viewer to prevent the first viewer right-eye and left-eye view from being viewed by an eye of the second viewer; wherein the light rays representing the second viewer right-eye and left-eye views are deflected towards the second set of eye-locations such that each light ray is directed to a second focused spot centered on an eye of the second viewer; and wherein the second focused spot is larger than an eye of the second viewer by an amount configured to facilitate a target amount of movement of the second viewer.
