1. An input device comprising:

  • a surface;

    a sensor configured to sense objects in a sensing region proximate the surface;

    a plurality force sensors, each of the plurality of force sensors coupled to the surface such that the plurality of force sensors provide a plurality of measures of force applied to the surface;

    a processing system coupled to the sensor and to the plurality of force sensors, the processing system configured to;

    determine positional information for each of multiple objects sensed by the sensor in the sensing region; and

    determine force information for the each of the multiple objects from;

    the positional information for each of the multiple objects; and

    the plurality of measures of force applied to the surface.
