Claim Text:
1. An adaptive sampling apparatus for spatial plane-based sampling corresponding to coverage of a user's contact with a touch screen display during a touch event, comprising: a touch sensor array, having a plurality of N sensing points whereby multiple points within a predetermined two-dimensional portion of a touch screen display are simultaneously sensed, wherein N is a positive integer; a driver unit, coupled with said sensor array; and a control unit, coupled with said driver unit; wherein said control unit has at least one adaptive sampling mode for controlling said driver unit to drive M regions determined according to an area corresponding with said coverage of a user's contact with a touch screen display sensed by the N touch sensing points of said sensor array and derive M sensed data from said M regions, wherein M is a positive integer and M<N, and each of said M regions includes at least one of said N touch sensing points, wherein said at least one of said N touch sensing points are combined to form one joined sensing unit for touch sensing whereby M is adaptable to said area corresponding with coverage of a user's contact with a touch screen display area during said touch event, and wherein said control unit operates in said at least one adaptive sampling mode selected from a group consisting of a spatially skipping sampling mode wherein each of said M regions has only one touch sensing point thereof activated for touch sensing, and a sensing-points-combined sampling mode wherein each of said M regions has all touch sensing points therein.
