Lightfield Display

About

Description: The purpose of the Steerable Lightfield Display is to provide large-scale stereoscopic viewing to one or more binocular observers standing at various distances in front of a large display screen, while allowing each eye of each observer to simultaneously be shown a different image.  As display screens increase in size, it becomes prohibitively expensive to achieve the above-stated purpose by use of an electro-optically active screen, such as one composed of computer-switched liquid crystal elements.  For this reason, the display described herein relies only on a passive display screen.   Features and Benefits: In this way, large-sized custom stereoscopic viewing is supported for multiple simultaneous observers, upon a single passive display screen.   Applications: Multiple observers can watch the same movie or interactive presentation simultaneously, with all figures and text tables customized in a way that is most appropriate for each observer, such as being translated into the language of that observer's choice, or showing sales figured, test scores, etc., appropriate to his or her situation.  Also, a person giving a presentation can see his notes upon the screen, while those notes remain invisible to others on the room.  Similarly, a presentation containing sensitive material can be given to different people who have different levels of security clearance, allowing only those persons who have the required level of permission to see certain privileged information in the presentation.  Also, the display allows a group of people to participate in interactive teleconferences.
