Abstract
A method includes: placing a first physical object at each of a first plurality of locations on a trackpad; while the first object is at each of the first plurality of locations, registering respective first readings from each of a second plurality of force sensors of the trackpad, the first plurality greater than the second plurality; selecting a first plurality of sensitivity parameters for the trackpad based at least in part on the first readings; and providing the first plurality of sensitivity parameters to force sensing circuitry of the trackpad, the force sensing circuitry coupled to the second plurality of force sensors.
