Abstract
In some examples, an electronic device can classify patches of touch data obtained by a touch screen as corresponding to intentional user inputs or not corresponding to intentional user inputs. The device can include a touch screen on a first side of housing of the device and a drive electrode on a second side of the housing of the device in some examples. In some examples, the drive electrode on the second side of the housing of the device can apply a signal to the body of the user and the device can classify patches of touch data including characteristics of this signal as corresponding to intentional touches provided by the user. The device can perform subsequent operations in response to intentional touches provided by the user and forgo performing operations in response to patches of touch data that do not correspond to intentional touches provided by the user.
