Patent ID: 8477098

Claim:
A system for a 3 dimensional (3-D) user interface, the system comprising: one or more 3-D projectors configured to display a holographic image at a first location in a certain 3-D coordinate system; multiple sensors configured to sense, based on quadrilateral angle navigation to determine a touch point position within the certain 3-D coordinate system, user interaction with the holographic image within the certain 3-D coordinate system and to provide user interaction information; and a processor configured to: (i) receive the user interaction information from the multiple sensors; (ii) based on the received user interaction information, correlate the sensed user interaction with the holographic image using the certain 3-D coordinate system; and (iii) provide one or more indications responsive to a correlation of the user sensed interaction with the holographic image, wherein the one or more indications comprise displaying the holographic image at a second location in the 3-D coordinate system.
