Abstract:
1. A method for determining a displacement of a touch point, applied to a touch panel, comprising: obtaining the displacement according to a movement of the touch point on the touch panel; checking whether the displacement is within a predetermined range; and determining that the movement is valid when the displacement is within the predetermined range, wherein the movement of the touch point is detected within a time interval, and wherein the step of obtaining the displacement according to the movement of the touch point on the touch panel comprises: generating a plurality of reference displacements according to a start position of the touch point at a start point of the time interval and a plurality of end positions of the touch point at an end point of the time interval; performing a second calculation on the plurality of reference displacements to obtain the displacement, wherein the second calculation is an average calculation; and discarding selected abnormal reference displacements among the plurality of reference displacements prior to performing the second calculation.
