Abstract
A handheld electronic device has an outer face in which a user display and a navigation touch pad are located. The touch pad is adapted to provide a user input for controlling at least one function of the electronic device. A plurality of touch sensors are located at predetermined locations about the area of the touch pad and detect touching by a user's finger in order to provide an output control signal. A light source is associated with each touch sensor. A control unit receives input from the touch sensors and activates each light source in turn as the associated touch sensor is touched by a user, so that the user receives visual feedback as they are controlling the device.
