An interesting use of Active Shutter glasses technology (similar to the recent Sony patent) allows multiple users (2 in this case) to interact with a stereoscopic 3D touch-table from opposite sides, while maintaining proper head-tracked 3D stereo perspective for both.
Better still, two users viewing the same model city at the same time from different sides of the table could each see the 3D effect with the correct perspective for their position.
That’s because the glasses are wired to position and orientation sensors that track the wearer’s gaze, and the system uses this information to alter the image accordingly in real time for each user.
