Abstract: An apparatus and a method for resolving locations of two or more substantially simultaneous touches on a split touch-sensor device. The method may include detecting multiple substantially simultaneous touches on a touch-sensor device having multiple sections in at least one dimension of the touch-sensor device, and resolving locations of the multiple substantially simultaneous touches on the touch-sensor device without an all-points-addressable (APA) array. Resolving the multiple locations includes resolving a first location in a first section of the multiple sections and resolving a second location in a second section that is adjacent to the first section of the touch-sensor device. The apparatus may include a first set of sensor elements disposed in a first axis in a plane of a touch-sensor device, and a second set of sensor elements and a third set of sensor elements disposed in a second axis in the plane.
