Abstract:
1. A method of processing an input from a touch-plane operator input device, comprising: (A) determining a first location of a first touch on the touch plane operator input device; (B) determining a second location of a second touch on the touch plane operator input device; (C) comparing the first and second locations to obtain an indication of an amount of difference between the first and second locations; and (D) determining whether the indication of the amount of difference exceeds a predetermined amount, the predetermined amount comprising a first amount in an X-direction and a second amount in a Y-direction, and comparing a first amount of difference with the first amount and comparing a second amount of difference with the second amount; wherein steps (A)–(D) are performed by discrete logic circuitry; and wherein the discrete logic circuitry provides an event notification to a microprocessor when the indication of the amount of difference exceeds the first predetermined amount.
