Patent ID: 8294686

Claim:
A method comprising: receiving, by a computer, a first touch on a touch-sensitive device of the computer, the first touch having a first width and a first length; determining, by the computer, a first reliability value of the first touch based at least partly on the first width and the first length, the first reliability value indicating a first probability that the first touch is intentional; receiving, by the computer, a second touch on the touch-sensitive device after receiving the first touch, the second touch having a second width and a second length; determining, by the computer, a second reliability value of the second touch based at least partly on the second width and the second length, the second reliability value indicating a second probability that the second touch is intentional; determining, by the computer, that the first touch and the second touch are each a portion of a third touch based at least partly on changes to the first reliability value and the second reliability value over time, the third touch having a third width greater than a combination of the first width and the second width and a third length greater than a combination of the first length and the second length; and rejecting, by the computer, the third touch based at least partly on the third width and the third length.
