Abstract: |
A portable or "lap-top" computer includes an associated head mounted display. The display is constructed in a manner similar to a pair of eyeglasses but with liquid crystal display screens replacing or forming a portion of the eyeglass lenses. The display screens can be either opaque or light transmitting, and can be hinge mounted to the glasses frame so that they can be swung up and out of the field of vision of the user. Specialized uses for the portable computer and head mounted display include a computer desk for secretarial workstations and the like, a research library workstation, and a moving map installation in an automobile or airplane.
