Abstract
A method of reducing the power consumption of an input device includes operating the input device at a first power level, detecting the presence of a touch object on a touch surface of the input device, determining that the presence of the touch object on the touch surface is static for a predetermined period of time, operating the input device at a second power level, maintaining the input device at the second power level, determining that the presence of the touch object on the touch surface is not static, and operating the input device at the first power level. In some cases, the touch object is a finger. The touch object is static if the touch object's position on the touch surface remains within a predetermined region, where the predetermined region is an area centered around the presence of the touch object on the touch surface.
