POSITION SENSING METHODS AND DEVICES WITH DYNAMIC GAIN FOR EDGE POSITIONING

摘要

A method can include determining an initial position of an object with respect to a sensing region formed by a plurality of sensors and having a core region bounded by at least one edge; if the initial position is proximate to the edge and a size of the object 5 was previously calculated, determining a final edge position of the object using the previously calculated object size; and if the initial position is proximate to the edge and the size of the object was not previously calculated, determining a size of the object.
