1. A method for estimating a finger force exerted by a finger on a touchpad in a computing device, the method comprising:
calculating a plurality of forces produced by a palm at a plurality of capacitive force sensors of the touchpad, wherein at least one of the sensors is saturated with a magnitude of force;
after calculating the plurality of forces produced by the palm, determining that the touchpad is being contacted by the palm and the finger; and
using the plurality of forces produced by the palm to determine the estimated finger force exerted on the touchpad by the finger.
