More Information
Summary:Embodiments may take the form of a system having a user input device and a first sensor coupled to the user input device. The first sensor is configured to sense touch on a surface of the user input device. The system may also include a second sensor in communication with the surface of the user device configured to sense wetting of a user's fingerprint on the surface. The system has a processor coupled to the first and second sensors and configured to estimate an amount of force applied by the user's fingerprint based at least in part upon the sensed wetting of the user's fingerprint.
