Abstract

The present invention discloses a horizontal perspective workstation comprising at least two display surfaces, one being substantially horizontal for displaying 3D horizontal perspective images, and one being substantially vertical for text or conventional images such as 2D images, or central perspective images. The horizontal display surface is typically positioned directly in front of the user, and at a height of about a desktop surface so that the user can have about a 45° angle looking. The vertical display surface is also positioned in front of the user and preferably behind and above the horizontal display surface. The present invention prefers a stereoscopic polarized horizontal perspective display, together with a polarized vertical display, thus the two images of the stereoscopic horizontal perspective display are mutually exclusive so that each image can be seen by the only corresponding eye, and the image of the vertical display is halfway polarized to be seen by both eyes. The horizontal perspective workstation can further comprise a binaural or 3D audio system to provide realistic sound simulation. The horizontal perspective workstation can also comprise various biofeedback devices such as brain wave, blood pressure, heart beat, respiration, perspiration, skin conductance, body temperature, muscle tension measurements and simulators for inputs and output with the users.

Claims

1. A 3-D horizontal perspective station system comprising

a horizontal perspective display using horizontal perspective to display a 3-D image on a substantially horizontal surface;

and

a non-horizontal perspective display showing information related to the 3-D image, displaying on a substantially vertical surface.

2. A system as in claim 1 wherein the non-horizontal perspective display displays 2D images or central perspective images.

3. A system as in claim 1 further comprising a peripheral device to manipulate the display images.

4. A system as in claim 3 wherein the manipulation comprises the action of modifying the display image or the action of generating a different image.

5. A system as in claim 1 further comprising a tracking unit.

6. A system as in claim 1 wherein the horizontal perspective display further comprises automatic or manual eyepoint tracking to synchronize a camera eyepoint of the horizontal perspective display with an user'"'"'s eyepoint.

7. A system as in claim 1 further comprising a processing unit.

8. A system as in claim 1 wherein the horizontal perspective display is a stereoscopic horizontal perspective display for displaying stereoscopic 3-D images.

9. A system as in claim 1 further comprising a a 3-D audio simulation system providing 3-D sound to a predetermined projection earpoint, the 3-D sound corresponded to the horizontal perspective images.

10. A system as in claim 1 further comprising a biofeedback device.

15. A system as in claim 1I1 further comprising a tracking unit.

17. A system as in claim 11 further comprising a biofeedback device.

11. A stereoscopic 3-D horizontal perspective station system comprising
