SYSTEM AND METHOD FOR REDUCING VIBRATIONAL EFFECTS ON A FORCE-BASED TOUCH PANEL

A system and method for reducing vibrational effects on a force-based touch panel is disclosed. The system comprises at least one force sensor operable with the force-based touch panel to measure a force applied to the touch panel to provide at least one force sensor signal. An accelerometer operable with the force-based touch panel is used to sense a vibrational acceleration of the force-based touch panel to form an acceleration signal. The vibrational acceleration adds a vibration induced signal to the at least one force sensor signal. An adaptive vibration filter is used to adaptively filter the vibration induced signal from the at least one force sensor signal by adjusting filter characteristics of the adaptive vibration filter to remove substantially all of the vibration induced signal from the at least one force sensor signal.
