Immersive Displays with Multiple Perspective Views
Providing multiple people with personal perspective views in augmented or virtual environments has traditionally been achieved through head-worn displays [7],
where each user has their own view on their own personal display. In practice, the obstruction of the face with such displays and their narrow field of view can lead to unnatural face-to-face interactions. Our solution avoids this difficulty. Alternatively, projection-bases systems rely on either time- or space-multiplexing the projected images to show multiple independent views. Agrawala et al.
[2] demonstrates a time- multiplexed approach with synchronized shutter glasses to enable two stereoscopic user perspectives on an interactive tabletop. While conceptually simple, this approach tends to suffer from low image brightness and sometimes perceivable flicker since each eye only gets a small slice of the available light in each frame.
