Abstract: A computer system and computer-implemented method for rendering images in real-time with a three-dimensional appearance. Using a database including at least-one pair of texture maps uses as a stereo pair behind a portal to simulate a scene. An input database can be processed to generate a processed database by performing texture mapping to replace at least one portion of the input data representing a view (or object) by data indicative of a pair of texture maps and an associated polygon or polygons. One of the texture maps represents the view (object) from a left-eye viewpoint; the other represents the view (object) from a right-eye viewpoint. In some embodiments, to generate the texture map pairs, the input database analyzed to produce the images. In other embodiments the images are from photographs or other sources.

Abstract: A data input glove for use with a computer system, virtual reality system or the like, with numerous electrodes place on the glove and interconnected with electronic controls enabling sensing of contact between any combination of the electrodes, with electrodes made of flexible electrically conductive fabric, silk-screened electrically conductive paint or the like.

Abstract: A compliant structure which includes a sensor for sensing translation and rotation of a top plate is disclosed. The structure is composed of a base plate and three supporting legs. The legs are compliant. The deflections of the structure are substantially in a plane and the translation and twist of the top platform may be measured by the gimbaled sensor assembly attached to one of the legs.

Abstract: A projection display system for use with a computer system. Used for immersive visualization and interaction tasks, the projection surface may be adjusted by the user to one of two positions. The image on the surface is generated by a computer and displayed by a projector on the table's surface.

Abstract: Describes the application of field-sequential color techniques to create a line field-sequential color display with particular advantages for head-mounted and head-coupled displays. The display is composed of a gray-scale CRT or other white display and a color shutter with fast switching time. The shutter is switched during blanking to create a color display in a sequential color fashion where the color fields are not entire frames.

Abstract: A method and apparatus for the control and manipulation of a virtual environment (such as virtual objects therein) in response to a music signal. The music is either interpreted directly to effect the control and manipulation. Alternatively, a control track corresponding to an audio signal (such as a music signal) is prerecorded, played back with the audio signal, and the control track is processed to control and manipulate the virtual world (or to control some other process of a computer system) as the audio signal is playing. In preferred embodiments, a computer creating a virtual world interprets the music, the control track, or both, and uses the resulting information to modify, create, and or control objects in the virtual environment. Preferred embodiments of the inventive system include apparatus for delaying input music to compensate for lag introduced by the system components, such as delay required to implement processing of control tracks corresponding to the input music.

Abstract: An image display method and system in which exertion of a user's viewpoint orienting muscle groups is yoked to sensors measuring displacement and/or force to provide feedback information for control of a virtual-world without requiring full physical-motion by the user. The yoked muscle exertion is mapped to the rate and direction of movement in the virtual-world. Preferably, force exerted by, and/or rotation or translation of, the yoking device in one direction in response to exertion of the muscle groups is mapped to virtual-motion in a corresponding direction in the virtual-world. Due to the fluidity of the human vertebral column, the invention effectively yokes rotational movement of a human's viewpoint orienting muscles to virtual movement in a virtual-world without the disadvantages of a head-mounted display. To orient toward an area-of-interest in a leftward portion of a virtual-world, the user simply and naturally activates muscles that would be used to orient left in the physical world.
