    Abstract: A signal processing system for detecting purposive signals includes an input receiving a signal having a signal characteristic subject to user manipulation. An activation detector compares a property of the signal characteristic to one or more signal characteristic property thresholds over time. A filter module determines whether the signal characteristic is purposively manipulated based on an amount of time preceding or following an occurrence of the property exceeding or falling below one or more signal characteristic property thresholds.
