1. A control interface for controlling a system, comprising a module comprising:
a carrier having a top surface and an opposite bottom surface;
an elongate window formed in, or adjacent, the carrier;
an elongate array of light sources on the bottom surface of the carrier;
a reflector arrangement for reflecting light from the array of light sources towards the window to escape from the top surface, such that a light path is formed between each light source and the window, with a portion of the light paths being parallel to the carrier, wherein the light sources are adapted to be turned on in response to a control signal;
wherein the module further comprises:
a user interface surface, comprising a track area for receiving touch input from a user, wherein the window is formed beneath the track area; and
a touch sensor circuit beneath the track area, wherein the touch sensitive circuit comprises a touch sensor region on the top surface of the carrier; and
a controller adapted to control the light sources in dependence on a detected location of a touch input.
