Abstract

A pointing device includes a navigation unit that generates position signals that indicate where a pointer is directed. The pointing device includes a selection unit that generates selection signals that indicate that a selection is made. The pointing device includes a sensor unit that generates an active signal that indicates that the pointing device is being handled. A transmission unit is coupled to the navigation unit, selection unit, and sensor unit. The transmission unit transmits the position signals, selection signals, and active signal to a remote location.

14. The driver of claim 9, wherein the active signal is indicative of the pointing device being held.

16. The medium of claim 15, further comprising instructions which, when executed by the machine, cause the machine to perform further operations comprising stopping the pointer display after a predefined period of time after the active signal is not received from the pointing device.

17. The medium of claim 15, further comprising instructions which, when executed by the machine, cause the machine to perform further operations comprising moving the position of the pointer in response to position signals received from the pointing device.

18. The medium of claim 17, further comprising instructions which, when executed by the machine, cause the machine to perform further operations comprising notifying a computer system that a selectable identifier on the display device has been selected in response to selection signals received from the pointing device.

20. The method of claim 19, wherein determining whether the pointing device is being handled comprises monitoring an interface for an active signal from the pointing device, the active signal indicating that the pointing device is being handled without a selection or position change being indicated.

21. The method of claim 19, wherein determining whether the pointing device is being handled comprises monitoring an interface for an active signal from the pointing device, the active signal indicating that a pressure sensor on the pointing device is being depressed.

22. The method of claim 19, wherein determining whether the pointing device is being handled comprises monitoring an interface for an active signal from the pointing device, the active signal indicating that a motion sensor on the pointing device is being triggered.
