Abstract: |
A virtual reality visual display system comprises a display device viewable by a user and a remote bounded-display-surface and stylus for entering data and graphics. The display device and remote bounded-display-surface each are equipped with sources of energy and communicate therebetween with radio or microwave radiation. The remote bounded-display-surface location and orientation in space is continuously transmitted to the display device whereby the virtual image of the bounded-display-surface is generated in the display device in mimicry of the actual surface. Application of the stylus to the bounded-display-surface causes the stylus tip location in space to likewise be transmitted to the display device and displayed as a virtual image. Thus, the bounded-display-surface can be "written-on" with the stylus regardless of orientation and a virtual representation complete with proper orientation displayed in real time on the display device.

First Claim:
Show all 20 claims |
I claim:
1. A visual display apparatus comprising viewable display means placeable on the head of a user and a bounded-display-surface remote from the viewable display means,
- said viewable display means comprising at least one display screen directly viewable by the user, means in electrical communication with the display means to energize and control the display means and electro-magnetic wave receiving means in electrical communication with the means to energize and control the display means, and
- said bounded-display-surfacecomprising at least one surface moveable in three dimensional space and having at least two boundaries, at least three locations each positioned at known distances from the at least two boundaries of the bounded-display-surface, electro-magnetic wave transmitter means attached to the bounded-display-surface and adapted to transmit the spacial positions of the at least three locations relative to the electro-magnetic wave receiving means, and
- computer means in electrical communication with the electro-magnetic wave receiving means and means to energize and control the display means whereby the bounded-display-surface is virtually rendered on the display screen.
