Abstract
A first set of classifier data and a different second set of classifier data are stored. Each of the first set and the second set is configured to differentiate between different types of touches on a touch sensitive screen including a capacitive based sensor. The first set is adapted to differentiate between different types of touches on a touch sensitive screen with no cover film added on the screen and the second set is adapted to differentiate between different types of touches when a cover film is added to the screen. The cover film is identified on the screen based on output from at least one conductive line or at least one array of conductive electrodes of the capacitive based sensor. The second set of classifier data is selected based on the identifying. A touch interaction is reported based on the second set of classifier data.
