Abstract

A touch sensitive film (1) includes a conductive layer (2) having a touch sensing region (3), and a user input surface (4). The user input surface of the touch sensitive film includes a tactilely distinguishable surface feature (5) deviating from the general nature of the user input surface (4) for identifying the location of the touch sensing region (3) by sensing the tactilely distinguishable surface feature.
