Abstract
Techniques are disclosed for direct viewer projection, which involves having each pixel's emitted light aimed at or otherwise provided directly to the target pupil of a viewing person. In one embodiment, the techniques are implemented using steerable, collimated light sources fashioned into an array to effectively provide a display screen. Each steerable, collimated light source of the array corresponds to one pixel of a given image at a given viewing location, such that no one light source shows a whole image; rather, the whole array is used to display an image. The array can be scanned to provide different images to different viewing locations. The content projected to the different locations may be related (e.g., a movie) or unrelated (e.g., two different movies). A specific viewer can be identified and tracked such that the content is only projected to the target viewer's eyes and no one else's.
