Patent ID: 7825902

Claim:
A method of operating a touch pad, the method comprising: providing a first set of detection paths comprising pairs of adjacent detection paths aligned in a first axial direction of the touch pad; providing a second set of detection paths comprising pairs of adjacent detection paths aligned in a second axial direction of the touch pad, the second axial direction intersecting the first axial direction; generating a first set of coordinates corresponding to the first axial direction, the first set of coordinates identifying at least one pair of adjacent detection paths aligned in the first axial direction that is affected by a first touch upon the touch pad; generating a second set of coordinates corresponding to the second axial direction, the second set of coordinates identifying at least one pair of adjacent detection paths aligned in the second axial direction that is affected by the first touch upon the touch pad; parsing the first and the second set of coordinates for identifying the first touch upon the touch pad; further using the first set of coordinates for identifying additional pairs of adjacent detection paths aligned in the first axial direction that are affected by a second touch and a third touch upon the touch pad; and further using the second set of coordinates for identifying additional pairs of adjacent detection paths aligned in the second axial direction that are affected by at least one of the second touch or the third touch upon the touch pad.
