Abstract
A system for determining at least one point of application of force on a surface element is provided. The system includes a surface element having an effective mass, at least one sensor configured to measure force applied on the surface element at least one acceleration sensor configured to measure acceleration in at least one direction, and a processing unit configured to receive, from the at least one sensor, signals indicating force applied on the surface element, to receive, from the at least one acceleration sensor, signals indicating acceleration, to filter out a disturbing force, determined based on acceleration signals and the effective mass of the surface element, from the signals indicating the force applied on the surface element, and to determine, based on the filtered signals, at least one point of application of force on the surface element.
