position determination utilizing a cordless device
First Claim
1. A system for generating position information, the system comprising:
- a reflector;
an image collection system configured to generate a first set of image data and a second set of image data, wherein the first set of image data includes a stronger indication of the reflector than the second set of image data; and
a processor configured to use the first set of image data and the second set of image data to generate position information related to the reflector.

Abstract
A system for generating position information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data can be collected in many different ways and may include using a retroreflector as the reflector. The two sets of image data are used to generate position information related to the reflector. In particular, position information related to the reflector is generated by taking the difference between the two set of image data. Because one set of image data includes a stronger indication of the reflector than the other set of image data, the difference between the two sets of image data gives a definitive indication of the reflector'"'"'s position.

35. A system for generating position information, the system comprising:
-
a pointing device comprising a retroreflector;
an image collection system configured to generate a first set of image data and a second set of image data, the image collection system comprising a light source and an imager, wherein the retroreflector, the light source, and the imager are oriented with respect to each other such that a portion of light generated by the light source is reflected by the retroreflector and detected by the imager to generate the first set of image data and the second set of image data; and
a processor configured to generate position information related to the pointing device from the first set of image data and the second set of image data. - View Dependent Claims (36, 37)
