Three dimensional horizontal perspective workstation
The present invention discloses a horizontal perspective workstation comprising at least two display surfaces, one being substantially horizontal for displaying 3 D horizontal perspective images, and one being substantially vertical for text or conventional images such as 2 D 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 3 D 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.
