Three-dimensional display system

Abstract

A three-dimensional display system comprises a display housing and a plurality of projectors for projecting two-dimensional images into a space, each projector having means to adjust the distance between the projector and the projected image, and each projector being pivotally mounted to the display housing, for adjusting the horizontal and vertical position of the projected two-dimensional image with respect to the projector. The display provides a high-resolution, three-dimensional multi-coloured image which can be touched safely by the viewer. The display may be respond to physical objects in the display area by altering the image. The display may be used to operate a computer and browse the world wide web.

         6 . The three-dimensional display system of  claim 1 , wherein each projector includes a light source, a display screen, and a zoom lens. 
     
     
         7 . The three-dimensional display system of  claim 6 , wherein the display housing comprises a narrow end and a wide end, and wherein the display screen is disposed near the narrow end and the zoom lens is disposed near the wide end. 
     
     
         8 . The three-dimensional display system of  claim 1 , wherein each projector further comprises a wavefront modulator. 
     
     
         9 . The three-dimensional display system of  claim 1 , wherein the display housing comprises a shape of an elongated square prism. 
     
     
         10 . The three-dimensional display system of  claim 1 , wherein each symbol is projected in a part of an electromagnetic spectrum which is invisible to a human eye. 
     
     
         11 . The three-dimensional display system of  claim 1 , wherein each symbol is projected in ultraviolet light. 
     
     
         12 . The three-dimensional display system of  claim 1 , wherein each symbol is projected in infrared light. 
     
     
         13 . A computer-implemented method comprising:
 displaying a first web page on a three-dimensional display system, the first web page comprising a hyperlink to a second web page, each web page designed for standard two-dimensional display and comprises a three-dimensional style defining a three-dimensional location of each web page component,   detecting whether an appendage of a user adjacent to the displayed first web page is close to the hyperlink; and   subsequent to detecting the user is close to the hyperlink, reducing a size of the first web page and displaying on the three-dimensional display system the second web page at a larger size.   
     
     
         14 . The computer-implemented method of  claim 13 , wherein at least one web page is written in a markup language which defines the three-dimensional location of each component of the at least one web page. 
     
     
         15 . The computer-implemented method of  claim 13 , further comprising adjusting, by a computer, an image position on the three-dimensional display based on a position of a head of a user tracked by the camera. 
     
     
         16 . The computer-implemented method of  claim 13 , wherein the three-dimensional display system comprises:
 a display housing;   a camera comprising a video signal;   a plurality of projectors, each projector configured to simultaneously project two-dimensional image components into a three-dimensional display, each two-dimensional image component comprising a symbol, each symbol projected in a pre-determined image component; and   an image-processing system communicatively connected to the camera and the plurality of projectors, the image-processing system configured to detect scattering of each symbol from the video signal, and determine an external objects position based on an absence of each symbol.   
     
     
         17 . The computer-implemented method of  claim 16 , wherein each projector comprises an adjustable throw and is pivotally mounted to the display housing for adjusting horizontal and vertical positions of the projected two-dimensional image component with respect to the projector. 
     
     
         18 . The computer-implemented method of  claim 16 , wherein each projector includes a light source, a display screen, and a zoom lens.
