Abstract

The personal computer is perfectly suitable for horizontal perspective display, designed for the operation of one person, and well capable of rendering various horizontal perspective images to the viewer. Thus the present invention discloses a real time electronic display that can adjust the horizontal perspective images to accommodate the position of the viewer. By changing the displayed images to keep the eyepoint point of the horizontal perspective image in the same position as the viewer's eye point, the viewer's eye is always positioned at the proper viewing position to perceive the three dimensional illusion, thus minimizing viewer's discomfort and distortion. The display can accept manual input such as a computer mouse, trackball, joystick, tablet, etc. to re-position the horizontal perspective images. The display can also automatically re-position the images based on an input device automatically providing the viewer's viewpoint location.

Dependent claims

A method of real time three dimensional image display by horizontal perspective projection, the horizontal perspective projection comprising a display of horizontal perspective images according to a predetermined projection eyepoint, the method comprising the steps of:

detecting an eyepoint movement of a viewer;
getting a new eyepoint location of the viewer with respect to the old eyepoint location corresponding to the eyepoint movement;
and
displaying a horizontal perspective image using the new eyepoint location as the projection eyepoint,
wherein the horizontal perspective image shows a different view corresponding to the eyepoint movement of the viewer.
