Abstract
A system for enabling two different users to independently view and listen to two completely different programs on the same display at the same time is provided. A user wears eyeglasses with filters to filter out light from the program which the user does not want to view, while allowing the light from the program the user does want to view to be seen by the user. Successive frames of a first program are displayed using light polarized in one direction in an alternating manner with frames of a second program using light polarized in another direction. A first user wears glasses with lenses configured to filter out the light from the second program while a second user wears glasses to filter out the light from the first program. Thus, while wearing the glasses, the first user can see the first program while watching the display, but not the second program. Simultaneously, while wearing the other glasses, the second user will see the second program, but not the first program.
