Abstract
A method for determining a stimulus is provided. The method includes determining a touch condition based on the rate of change of electrode capacitance, measuring a characteristic of the electrode capacitance in response to the touch condition being met, and evaluating the measured characteristic to determine the touch stimulus. The method can improve the ability to determine a touch stimulus over existing methods, including the ability to determine fingerprint and handprint biometrics, for example.
