Abstract
A method and system for enabling interaction with unmodified 3D graphics applications using face-tracking. The method includes determining a position of a viewer using face-tracking component and transforming a viewer's position to application coordinates. The application coordinates are passed to a wrapper library around a 3D graphics application's library. The 3D graphic application's instruction stream is altered to display 3D graphics on a display with scenes rendered as seen from the viewer's position. The 3D graphics application is forced to load a wrapper library which overloads functions of the underlying 3D graphics application library. In this way, the 3D graphics application can be an existing unmodified 3D graphics application provided on a computer system.
