摘要: A technique for recognizing and rejecting false activation events related to a capacitance sense interface includes measuring a capacitance value of a capacitance sense element. The measured capacitance value is analyzed to determine a baseline capacitance value for the capacitance sensor. The capacitance sense interface monitors a rate of change of the measured capacitance values and rejects an activation of the capacitance sense element as a non-touch event when the rate of change of the measured capacitance values have a magnitude greater than a threshold level, indicative of a maximum rate of change of a touch event.

摘要: A technique for recognizing and rejecting false activation events related to a capacitance sense interface includes measuring a capacitance value of a capacitance sensor within the capacitance sense interface to generate a measured capacitance value. The measured capacitance value is analyzed to determine a baseline capacitance value for the capacitance sensor. The baseline capacitance value may be updated based at least in part upon a weighted moving average of the measured capacitance value. The measured capacitance value may also be analyzed to determine whether the capacitance sensor was activated during a startup phase and to adjust the baseline capacitance value in response to determining that the capacitance sensor was activated during the startup phase.

摘要: A technique for improving capacitive sensing accuracy. Concurrent activations of multiple capacitance sensors within an array of capacitance sensors are sensed. One of the concurrent activations of the multiple capacitance sensors is accepted as a user activation. Remaining ones of the concurrent activations of the multiple capacitance sensors are rejected based on their physical location within the array of capacitance sensors relative to the one of the concurrent activations of the multiple capacitance sensors accepted as the user activation.
