A portable electronic device comprising a display (200) arranged on a first side of the device (10). The display (200) has a first touch sensitive surface (200). The device comprises a second touch sensitive surface (310) separate from the display (200) 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 touch sensitive surface (200) and the second touch sensitive surface (310), for detecting touch input regions (605,610,615,620,625) 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 (605,610,615,620,625) are assigned to corresponding user control commands so that at least a first subset (610,615,620,625) of the user control commands correspond to touch input regions on the first touch sensitive surface (200) and at least a second subset (605) of the user control commands correspond to touch input regions on the second touch sensitive surface (310). |
