1. A method for operating a pointing device in a low power manner, comprising:
- receiving first tracking information from a first tracking device;
periodically determining accuracy of the first tracking information by a microcontroller; and
activating and using a second racking device to acquire second tracking information when said determining indicates the accuracy of the first tracking information is inadequate, wherein the first tracking device is substantially lower power device that the second tracking device.

Abstract
A low power tracking device and a method of use thereof is described. The method includes receiving first tracking information from a first tracking device and periodically determining accuracy of the first tracking information. A second tracking device is activated and used to acquire second tracking information when said determining indicates that the accuracy of the first tracking information is inadequate. The first tracking device is substantially lower power device that the second tracking device.

9. A hybrid tracking system suitably arranged to provide tracking information to a computer, comprising:
-
an optical tracking engine arranged to provide the tracking information to the computer; a low power inertial tracking engine arranged to provide the tracking information to the computer, and an adaptive duty cycle signal generator coupled to the optical tracking engine and the inertial tracking engine arranged to compare tracking information provided by the low power inertial tracking engine and provided by the optical tracking engine such that when the comparison is valid, the adaptive duty cycle signal generator provides a first duty cycle signal that deactivates the optical tracking engine such that only the low power tracking engine provides the tracking information to the computer. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
