1. A method for touch detection, the method comprising:

  • receiving first touch data comprising a first plurality of touch detections recorded at a first time;

    receiving second touch data comprising a second plurality of touch detections recorded at a second time;

    matching, for several matches, a plurality of the first plurality of touch detections to a corresponding plurality of the second plurality of touch detections, wherein the plurality of the first plurality of touch detections and the corresponding plurality of the second plurality of touch detections comprise a first set and a second set, and matching, for each match, further comprises;

    computing a rotation and translation matrix between the first set and the second set;

    applying the rotation and translation matrix to the first set to determine a result; and

    calculating a Euclidian distance between the result and the second set; and

    selecting a match, from the several matches, having a minimum Euclidian distance.
