Method and apparatus for the perception of computer-generated imagery
First Claim
1. A method for presenting different computer-generated images of an object to respective eyes of a person viewing said object whereby said object is perceived stereoscopically, the method comprising:
- locating in a fixed relation to each eye of said person means to project a different image of said object into said eye,monitoring a line of sight of each said eye and an angle of convergence of said lines of sight,computer-generating two different images of said object as viewed by said eyes at the same spatial coordinates relative to said person, andmodifying each image according to variations in the relationship between said spatial coordinates and said angle of convergence.

Abstract
The invention relates to a 3-dimensional computer graphics system in which an operator can effectively interact with a virtual model generated and displayed by a computer. In one embodiment the operator wears a helmet fitted with means which enable both the location of his head and its coordinates relative to the virtual model to be monitored and the information sent to computer. The helmet carries miniature VDUs which direct separate images to his individual eyes so that the image is perceived stereoscopically. The movement of the operator'"'"'s eyes is also monitored by means mounted within housings of the helmet and data representing the operator'"'"'s direction of vision sent to the computer. The data transmitted to the computer is used to modify the image of the model as perceived by the operator to enhance its realism.

5. A three-dimensional display system comprising:
-
location means for maintaining a fixed relation relative to the two eyes of a user, means to project different images of a three-dimensional object into said eyes, means for monitoring a line of sight of each said eye of said user and for monitoring an angle of convergence of said lines of sight, computer means for generating two different images of the three-dimensional object, said images having common spatial coordinates, and for modifying said images in response to variations of a relationship between said spatial coordinates and said angle of convergence, such that the image presented to each eye is of said three-dimensional object as seen by said eye at a distance from said user determined by said angle of convergence whereby said user perceives said object stereoscopically. - View Dependent Claims (6, 7, 8)
