ABSTRACT:
Apparatus is disclosed for viewing computer generated images and for tracking the positions of the user's head and hand. One alternative of the apparatus includes a frame element, versatilely mountable, with sensors for the head tracking of a user whose bodily movement is constrained to a small area. Short range and inexpensive sensors are deployed for tracking the position of the user's head; these sensors are deployed partly on a on the user's head and partly on the tracking frame. All the electronics for tracking and user input are enclosed in a mobile pack. In another alternative of the tracking invention natural forces such as gravity, the Earth's magnetic field, and inertia are used, so additional references. The display allows for interchangeable optical elements so that it may be tailored to suit the needs of a particular user or application. One optical element disclosed is a bicolor polarizer, which allows an lcd to inexpensively provide a bicolor display without loss of resolution.
