1. A method, comprising:
- determining multiple sensed positions of an object path in a touch sense region;
generating at least a first predicted position from the sensed positions; and
filtering a sense position, includingassociating the sense position with the object path if it is within a first proximity to at least the first predicted position, andnot associating the sense position with the object path if it is outside of at least the first proximity from the first predicted position.

Abstract
A method can include determining multiple sensed positions of an object path in a touch sense region; generating at least a first predicted position from the sensed positions; and filtering a sense position, including associating the sense position with the object path if it is within a first proximity to at least the first predicted position, and not associating the sense position with the object path if it is outside of at least the first proximity from the first predicted position.
