Zusammenfassung:	A system and method are described for selectively controlling polling of a signal representing displacement information of an analog input device included in a hand-held computing device. In one embodiment, the analog input device generates a signal representing a displacement of the input device. A switch directs the signal to a threshold detector system, which determines whether the signal exceeds a predetermined threshold. If the threshold is exceeded, the threshold detector system generates an interrupt. The switch then directs the signal to a processor that is configured to receive a digitized version of the signal and to poll the digitized signal at a higher specified frequency.
