Direct viewer projection

摘要

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.

主权项

1. A method for displaying content to a viewing area, comprising:
receiving image data to be rendered by a direct view display, the direct view display including an array of collimated steerable light sources, each light source corresponding to a pixel of the display; generating control signals based on the image data, for driving the array of collimated light sources to provide a first image at a first viewing location in the viewing area; adjusting the array of collimated light sources to point to a second viewing location in the viewing area; and generating control signals based on the image data, for driving the array of light sources to provide a second image at the second viewing location.
