SIGNALING DEVICE POSITION DETERMINATION |
摘要 |
<p>A system and method for providing user input to a device. A system includes a light source, a user positioned signaling device, an image capture device, and an image processor. The user positioned signaling device includes a retroreflective structure and a polarization retarder. The image capture device captures images of the signaling device. The image processor processes the captured images and determines a position of the signaling device based, at least in part, on light polarized and reflected by the signaling device.</p> |
