    摘要： 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.

    摘要： 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.

    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.

    摘要： 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.

    摘要： An interactive, autostereoscopic system for displaying an object in 3D includes a mirror configured to spin around a vertical axis when actuated by a motor, a high speed video projector, and a processing system including a graphics card interfaced to the video projector. An anisotropic reflector is bonded onto an inclined surface of the mirror. The video projector projects video signals of the object from the projector onto the inclined surface of the mirror while the mirror is spinning, so that light rays representing the video signals are redirected toward a field of view of a 360 degree range. The processing system renders the redirected light rays so as to interactively generate a horizontal-parallax 3D display of the object. Vertical parallax can be included in the display by adjusting vertically the displayed views of the object, in response to tracking of viewer motion by a tracking system.
