<p><P>PROBLEM TO BE SOLVED: To improve the detection range and sensitivity of a capacity type touch control sensing device. <P>SOLUTION: In this identification method for the touch control sensing device, the touch control sensing device has a touch control pad and a memory, and the touch control pad is connected to at least one equivalent capacity. The method comprises steps of (a) charging the equivalent capacity to obtain at least a potential reference value, (b) storing each potential reference value in the memory, (c) touching the touch control pad, (d) scanning the touch control pad to obtain at least one potential fluctuation value of each equivalent capacity, and (e) comparing each potential reference value with each potential fluctuation value relative to each potential reference value to identify a touched position on the touch control pad. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
