Wireless pointing system
First Claim
1. A wireless pointing device receiver, comprising:
- a receiver to receive signals from at least two wireless pointing devices; and
a control circuit to detect movement of each of said devices relative to said receiver, said control circuit including at least two detectors, said control circuit to compare inputs from said wireless devices to the detectors to detect movement of each device relative to said receiver.

Abstract
A wireless pointing device may have a motion circuit to indicate when the wireless pointing device is in motion, and a transmitter to transmit a unique signal indicative of the wireless pointing device'"'"'s motion is described. A wireless receiver may have a control circuit to generate control signals based on a classification of signals received from the wireless pointing device, and an analysis circuit to determine a characteristic of the received signals is also described. Signal classification may include determination of whether the received signal indicate motion of the wireless pointing device and/or whether a wireless pointing device control (a button or switch, for example) has been activated. Signal characteristics may include motion and/or the speed of motion of the wireless pointing device.
