Abstract:
1. A hand-held portable device, comprising: a touch sensitive surface providing at least one input element; a processing device in communication with the touch sensitive surface having associated instructions; and a sensor for providing to the processing device a signal indicative of a position of the hand-held device relative to an object surface; wherein the instructions associated with the processing device use the signal indicative of the position of the hand-held device relative to the object surface to cause the processing device to both selectively enable the at least one input element provided by the touch sensitive surface and to selectively manage power provided to the sensor and wherein the processing device selectively manages power provided to the sensor by causing power to be provided to the sensor at a first time interval after the hand-held device is indicated to be in a position that is stationary and adjacent relative to the object surface, by causing power to be provided to the sensor at a second time interval shorter than the first time interval after the hand-held device is indicated to be in a position that is moving and adjacent relative to the object surface, and by causing power to be provided to the sensor at a third time interval after the hand-held device is determined to be in a position that is removed relative to the object surface.
