1. A method comprising:
- detecting a plurality of activated touch-sensor buttons on a touch-sensor array, each of the plurality of activated touch-sensor buttons comprising an active area of the touch-sensor array including a plurality of touch-sensor elements;
determining a difference value corresponding to a difference between activation signal values for different buttons of the plurality of activated touch-sensor buttons on the touch-sensor array;
comparing the difference value to a difference threshold; and
when the difference value is above the difference threshold;
determining which of the plurality of activated touch-sensor buttons has a greater activation signal value; and
triggering an operation associated with a touch-sensor button of the plurality of activated touch-sensor buttons determined to have the greater activation signal value.

Abstract
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.
