摘要： A wireless location and identification system includes a controller and a tag. The controller has a projector configured to generate a unique temporal sequence of light intensities for each pixel in an output image of the projector and a wireless transceiver configured to emit an output signal and receive an input signal. The tag includes a photo-sensor configured to sense the unique temporal sequence of light intensities of a particular pixel, a transducer configured to receive the output signal from the transceiver, and a means for modulating, according to the unique temporal sequence of light intensities, the input signal for the transceiver in response to receiving the output signal and sensing the unique temporal sequence of light intensities of the particular pixel to indicate a location of the tag to the controller.

摘要： A method adjusts a pose of a projector with respect to a display surface. A homography HD,P is determined between a display surface and a projector. The homography HD,P is decomposed into rotation and translation parameters expressing a pose MP of the projector. An ideal pose M0 of the projector corresponding to an ideal homography H0 is determined. A pose adjustment MA is determined according to MA=M0(MP)−1. The pose adjustment MA is decomposed into rotation and translation adjustment parameters. Then, the projector is adjusted mechanically to the ideal pose M0 according to the rotation and translation adjustment parameters.

摘要： A method generates input text with a pointing device at a distance from a writing surface. Motion information of a mobile coordinate frame of the pointing device is sensed relative to a stationary coordinate frame of the writing surface using a motion sensor configured to track motion of the pointing device. The input text is then determined from the motion information. A projection of a track of the motion of the pointing device on the writing surface can also be determined from the motion information, and the track can be displayed on the writing surface as the input text.
