Abstract
A process determines touch orientation of touches on a sense array of a touch-sensing device. The process obtains first touch data and second touch data of a conductive object proximate to the sense array at two temporally proximate times. The first and second touch data are then used to determine a first touch orientation, and the second touch data is used to determine a touch area and a provisional touch orientation. A touch orientation change is then determined as an absolute difference between the first touch orientation and the provisional touch orientation. The touch orientation change is compared with a threshold change, and the touch area is compared with a threshold area. In accordance with comparison results, the first touch orientation, the provisional orientation, or a weighted combination of them is designated as a second touch orientation corresponding to one of the two temporally proximate times.
