Abstract: A portable electronic device comprising a display arranged on a first side, the display having a first touch sensitive surface. The device also comprises a second touch sensitive surface separate from the display and a processor responsive to a plurality of user control commands. The device further comprises a touch detector, responsive to a user touching at least one of the first and second touch sensitive surfaces, for detecting touch input regions each corresponding to a respective one of the user control commands and for initiating a response, by the processor, to a user control command corresponding to a detected touch input region. The touch input regions are assigned to corresponding user control commands so that at least one subset of the commands corresponds to touch input regions on the first surface and at least another subset of the commands corresponds to touch input regions on the second surface.
