Title: ADAPTIVE SAMPLING OF TOUCH SCREEN INPUT
Abstract:
A touch screen input device (10) includes a display screen (12) adapted for receiving a touch input from a user; means (14) for sampling the touch screen input at any one of a plurality of sampling rates; means (18) for storing a predetermined sampling rate (28) for each application or for each function; and means (16) for setting the sampling rate of the sampling means (14) to the sampling rate (28) stored for a given application or a given function whenever that given application is being executed or that given function is being performed, respectively. In an alternative embodiment, the rate of change (R) of the touch screen input sample points is measured and the sampling rate (f) increased or decreased when the rate of change (R) of the sample points increases or decreases, respectively.
