Abstract
In one embodiment, a method for operating an electronic device includes determining that a touch sensitive display is being contacted. The touch sensitive display includes a plurality of mutual-sensing capacitive sensor regions and an array of self-sensing capacitive sensor regions. The plurality of mutual-sensing capacitive sensor regions is arranged in rows and columns on the touch sensitive display. The array of self-sensing capacitive sensor regions is arranged in a row or a column on the touch sensitive display. The method may include obtaining mutual sensing touch values for each of the rows and the columns and self-sensing touch values for the row or the column. Based on the mutual sensing touch values and self-sensing touch values, the method includes determining whether a contacted region of the touch sensitive display is an impression of a single finger, multiple fingers, a single thumb, or multiple thumbs.
