Abstract
Embodiments present different images to multiple viewers of a shared display using glasses with lenses that transmit only selected images from the display. The images viewed by each of the glasses may be based on the tracked position and orientation of the glasses, so that the images correspond to the user's viewpoint. Different images may also be presented to left and right eyes for 3D stereoscopic viewing. The position and orientation of the lenses of the glasses may be tracked by analyzing images from one or more cameras observing the glasses. Glasses may have distinctive geometric shapes or features, such as circular lenses or rims, or recognizable blobs or patterns, to facilitate tracking. The lenses of the glasses may combine multiple barriers such as anaglyph filters, polarizing filters, and shutters, to select images from the display. Glasses may also be used as pointing devices to select and manipulate 3D objects.
