Patent ID: 8884911

Claim:
A resistive touch controlling system, comprising: a first sensing module, comprising a plurality of sensing line groups, wherein each sensing line group corresponds to a specific sensing area on a resistive touch screen of the resistive touch controlling system; a second sensing module; and a processing circuit, being electrically coupled to the first sensing module and the second sensing module, and when at least a first object and a second object touch the resistive touch controlling system to cause the first sensing module sensing at least two touch points, for taking a combination of touch points sensed by the first sensing module and the second sensing modules as a first candidate list, thereafter for activating a switch to couple some of the sensing line groups of the first sensing module sensing one of the sensed touch points to ground and for taking a touch point(s) sensed by the first sensing module and the second sensing module at this situation as a second candidate list, and then for comparing the first candidate list with the second candidate list to determine a current touch sensing result.
