1. A system comprising:

  • a user input device;

    a first sensor coupled to the user input device, wherein the first sensor is configured to sense touch on a surface of the user input device;

    a second sensor configured to sense a characteristic of a user'"'"'s fingerprint on the surface;

    a processor coupled to the first and second sensors and configured to estimate an amount of force applied to the surface by the user'"'"'s finger based at least in part upon the sensed characteristic of the user'"'"'s fingerprint, said characteristic measured by an evaluation of ridges to valleys within a contact area in the user'"'"'s fingerprint.
