Patent ID: 8207948

Claim:
A method of identifying objects on a touch-sensitive device, the method comprising: scanning a plurality of “m” traces of the touch-sensitive device, m being a positive integer; obtaining a count value of each of the “m” traces, wherein an x-th trace has a count value a x , x being an index number from 1 to m; comparing a count value a; with a count value a i+1 in an increasing order of index number in a first comparison process until a count value a j not smaller than a j+1 is identified, i and j being positive integers; and based on the count value a j , comparing the count value a j with one of count values following a j in an increasing order of index number in a second comparison process until a count value a k is identified, k being a positive integer, wherein a difference between the count values a i and a k satisfies a first threshold.
