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 method for inserting advertisements into streaming audio for transmission over a world wide network of computers. The method includes transmitting audio data from a first server location to a client location. The audio data include a flag and audio content data. The method also includes monitoring the audio data and identifying the flag on the audio data. A step of inserting an advertisement, which is based upon a user profile, into the audio data based upon the flag is also included. The method also outputs the audio content data comprising the advertisement.
摘要:
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.
摘要:
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.
摘要:
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.
