Abstract
A system for generating position information includes a computing device and a position determination system that is configured to determine the position of a passive pointing element. In an embodiment, the position determination system is integrated into the computing device and includes two detectors that determine the linear or angular position of the passive pointing element, from which triangulation is used to identify the two dimensional position of the passive pointing element. Because the triangulation detectors determine the linear or angular position of the passive pointing element without active input from the passive pointing element, the passive pointing element can be unpowered and untethered.

18. A method for generating position information, the method comprising:
-
making two position measurements related to a passive pointing element that is within a detection area established adjacent to a computing device, the position measurements being made without active input from the passive pointing element;
deriving position information related to the pointing element from the two position measurements; and
using the position information to navigate a user interface. - View Dependent Claims (19, 20)
