Discriminating among activation of multiple buttons
An apparatus and method for discrimination of activation of multiple buttons are described. To discriminate among the activations, a processing device detects multiple activated touch-sensor buttons on a touch-sensor array. The processing device determines a difference value corresponding to a difference between activation signal values for each of the activated touch-sensor buttons and compares the difference value to a difference threshold. If the difference value is above the difference threshold, the processing device determines which of the activated touch-sensor buttons has a greater activation signal value and triggers an operation associated with that touch-sensor button.
