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.

Claims

1. 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 location of a viewer; and

displaying a horizontal perspective image using the detected eyepoint location as the projection eyepoint.

2. A method as in claim 1 wherein detecting a viewer eyepoint location is by manually inputting the location through a manual input device.

3. A method as in claim 1 wherein the detection of a viewer eyepoint location is through an automatic input device whereby the automatic input device automatically extracts the eyepoint location from the viewer.

4. A method as in claim 1 further comprising the step of manipulating the image.

5. 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 location of a viewer;

calculating a horizontal perspective image using the detected eyepoint location as the projection eyepoint; and

displaying the horizontal perspective image.

6. A method as in claim 5 wherein detecting a viewer eyepoint location is by manually inputting the location through a manual input device.

7. A method as in claim 5 wherein the detection of a viewer eyepoint location is through an automatic input device whereby the automatic input device automatically extracts the eyepoint location from the viewer.

8. A method as in claim 5 further comprising the step of manipulating the image.

9. 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:

continuously scanning to detect an eyepoint location of a viewer;

calculating a new horizontal perspective image using the detected eyepoint location as the projection eyepoint; and

displaying the new image.

10. A method as in claim 9 wherein the horizontal perspective image is stereoscopic images.

11. A method as in claim 9 wherein the horizontal perspective image is calculated from a flat two dimensional picture.

12. A method as in claim 9 wherein the horizontal perspective image is calculated from a three dimensional model.

13. A method as in claim 9 wherein detecting a viewer eyepoint location is by manually inputting the location through a manual input device.

14. A method as in claim 13 wherein the manual input device is a computer peripheral or a wireless computer peripheral.

15. A method as in claim 13 wherein the manual input device is selected from a group consisted of a keyboard, a stylus, a keypad, a computer mouse, a computer trackball, a tablet, a pointing device.

16. A method as in claim 9 wherein the detection of a viewer eyepoint location is through an automatic input device whereby the automatic input device automatically extracts the eyepoint location from the viewer.

17. A method as in claim 16 wherein the automatic input device is selected from a group consisted of radio-frequency tracking device, infrared tracking device, camera tracking device.

18. A method as in claim 9 further comprising the step of manipulating the image.

19. A method as in claim 9 wherein the manipulation of the image comprises the modification of the displayed image or the generation of a new image.

20. A method as in claim 9 wherein the modification of the displayed image comprises the movement, zooming or rotation of the image.
