摘要： An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. The pointing device captures images displayed by the computer, including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. Motion of the pointing device between the two frames is detected by relative motion sensors, and used to align the positions of the positioning targets in the captured images for those frames to improve the fidelity of the recovered positioning target following the subtraction.

摘要： An interactive display system and method of operating the same including a remote pointing device for controlling items displayed at a display, in which movement of the device is adjusted according to distance from the display. Distance of the device from the display is determined, and a sensitivity reduction factor corresponding to that distance is calculated. Physical movement of the device is interpreted as movement of a cursor position at the display, with the extent of that movement adjusted according to the sensitivity reduction factor. An additional sensitivity reduction factor corresponding to the speed of movement of the device may also be incorporated into the adjustment of the cursor position.

摘要： An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. An error value between the absolute position and an estimated or actual relative position at the point in time of the absolute position is determined, and a compensation factor is determined from this error value that is applied to subsequent relative positioning results.

摘要： An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. The pointing device captures images displayed by the computer, using a rolling shutter, the images including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. The capturing of images at the pointing device is synchronized with the release of image data to the display, to avoid errors in the positioning operation.
