Abstract: A multi-planar volumetric display system and method generate volumetric three-dimensional images using a multi-surface optical device including a plurality of individual optical elements corresponding to a plurality of image depths. An image projector selectively projects images on respective optical elements to generate a volumetric three-dimensional image viewable in the multi-surface optical device. Psychological vision cues are added during generation of the three-dimensional image to enhance depth perception when viewing the three-dimensional image. A floating-image generator may project the three-dimensional image having enhanced depth to generate a second volumetric three-dimensional image viewable as floating in space.

Abstract: An interface controller for a computer or other data processor which does not require physical contact between a pointing device and the controller. Methods and apparatus are disclosed for detecting coordinates associated with the violation of a plane or field in space by a pointing device such as a user's finger, and using the detected coordinates as input for controlling a data processor such as a digital computer. The interface controller is especially useful for controlling computers in which the user is presented not with a physical interface screen such as a CRT monitor, but with a projected virtual image of the screen.
