1. A system, comprising:
an accelerometer, configured to detect a touch gesture vibration at a detection surface and generate a vibration signal in response to the touch gesture vibration; and
a processing unit, coupled to the accelerometer, the processing unit configured to:
detect a signal characteristic of the touch gesture vibration;
detect a stationarity condition adjacent to the signal characteristic in a time sequence; and
validate a touch gesture in response to the signal characteristic and the stationary condition.
