摘要:
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.

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. At the same time, the effect of virtual-motion as the displayed image viewpoint moves is compelling because while the muscles are contracting, special sensory information is sent to the brain to indicate that such movement should be occurring.

A controllable lighting system may include a plurality of light source groups, a group controller for each light source group, a master controller, and a network communication system. Each group controller may be configured to control the light sources in its light source group based on a group control command. The master controller may be configured to receive a master control command relating to the light sources and to issue a group control command to each of the group controllers that collectively effectuate compliance with the master control command. The network communication system may be configured to communicate the group control commands from the master controller to the group controllers.

A rear projection imaging system with an image warping distortion correction system using a camera and processing unit to generate a warping map that corrects for image distortion. The warping map is generated in an iterative process by displaying a known pattern on a viewing screen and, through the use of a camera, having a microprocessor determine the location and shape of the pattern on the screen. The microprocessor then compares the displayed image to the original reference image, calculates the distortion effects present in the projection optics, and generates a warping map.

The multi-person stereo display system permits several independent viewers to see different stereo images on a single projection surface. This is accomplished through the innovative use of video multiplexing, software, control electronics, and special viewing glasses. The system is particularly useful in situations where the viewers see computer generated images from their own independent perspectives.

A compliant structure which includes a means 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.

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.

A head mounted display (HMD) for viewing a virtual environment generally include a flat display (FD), lenses for focusing on the FD, and a housing to enclose the FD and lenses. The housing is generally opaque to block out all external light, so the viewer only sees light from the FD. By making a portion or all of the housing translucent or transparent, ambient light and other external light can be seen by the viewer, providing additional visual cues and a larger perceived field of view. Additionally, other people can see light from the FD. The lenses are configured to view the FD and parts of the translucent housing.
