Abstract
Systems and methods are disclosed herein for determining the amounts of force applied by at least two fingers of a user to a touch input device having a touch input surface. In one example, a system may include a plurality of force sensors distributed about the touch input surface; a plurality of touch sensors distributed about the touch input surface; and a module for apportioning a first amount of force as measured by the plurality of force sensors to one of the at least two fingers, and for apportioning a second amount of force as measured by the plurality of force sensors to another of the at least two fingers. The system may also include a persistent data structure including force calibration data with force deflection measurement values as measured by each of the plurality of force sensors in response to a standardized force applied to various known locations on the touch input surface. The system may also include one or more matched filter modules.
