Bounded-display-surface system for the input and output of computer data and video graphics
First 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, andsaid 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, andcomputer 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.

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.

12. A method of displaying a sequence of virtual visual images comprising the steps of:
-
broadcasting locational information from a bounded-display-surface, receiving the locational information at receiving means spaced from the bounded-display-surface, computing a position in space of the bounded-display-surface relative to a viewable display means, generating an image of the bounded-display-surface on viewable display means, in response to a change in position in space of the bounded-display-surface relative to the viewable display means, recalculating the position in space of the bounded-display-surface relative to the viewable display means, and regenerating the image of the bounded-display-surface on the viewable display means. - View Dependent Claims (13, 14, 15)

16. A bounded display surface comprising 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 an electro-magnetic wave receiving means, and viewable display means located remotely from the bounded-display-surface, said electro-magnetic wave receiving means in communication with the viewable display means whereby the bounded-display-surface is virtually rendered to a user on the viewable display means, the viewable display means being placeable on the head of the user.
