Three dimensional horizontal perspective workstation

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.

Benefits of technology

[0013] The present invention discloses a horizontal perspective workstation employing a horizontal perspective display with a computer system. The personal computer is perfectly suitable for horizontal perspective display since it is designed for the operation of one person, and the computer, with its powerful microprocessor, is well capable of rendering various horizontal perspective images to the viewer. Further, horizontal perspective offers open space display of 3D images, thus allowing the hand-on interaction of the end users. Together with binaural or three dimensional audio, horizontal perspective workstation can offer a realistic simulation of the reality. Furthermore, with the addition of user biofeedback, horizontal perspective workstation could also tailor the simulation to suit a particular user.

[0015] The horizontal perspective workstation further comprises a computer system with standard peripheral devices such as a keyboard, a mouse, a trackball, a stylus, a tablet, a camera, a scanner, or a printer. The connections can be wired or wireless. The positions of these peripheral devices are flexible and usually arranged for achieving user's support and comfort.

[0018] Further, the horizontal perspective workstation can comprise curvilinear blending display surfaces to merge the various images. The horizontal perspective workstation can adjust the images to accommodate the position of the viewer. By changing the displayed images to keep the camera eyepoint of the horizontal perspective and central perspective images 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. The horizontal perspective workstation can provide a simulator system by allowing the user to manipulate the images with hands or hand-held tools.

Problems solved by technology

Ever since humans began to communicate through pictures, they faced a dilemma of how to accurately represent the three-dimensional world they lived in.

Sculpture was used to successfully depict three-dimensional objects, but was not adequate to communicate spatial relationships between objects and within environments.

Viewing the images at angle different from 90° would result in image distortion, meaning a square would be seen as a rectangle when the viewing surface is not perpendicular to the line of vision.

Horizontal perspective images offer realistic three dimensional illusion, but are little known primarily due to the narrow viewing location (the viewer's eyepoint has to be coincide precisely with the image projection eyepoint), and the complexity involving in projecting the two dimensional image or the three dimension model into the horizontal perspective image.

Further, with much experience in viewing three dimensional depth cues from perpendicular images, viewers can tolerate significant amount of distortion generated by the deviations from the camera point.

In contrast, the creation of a horizontal perspective image does require much manipulation.

Making a horizontal drawing requires much effort and very time consuming.
