Abstract

See full text

A control interface (10) for controlling a system, comprising a module comprising: a carrier (32) having a top surface and an opposite bottom surface; an elongate window formed in, or adjacent, the carrier; an elongate array of light sources (36) on the bottom surface of the carrier; a reflector arrangement (40) for reflecting light from the array of light sources towards the window (38) to escape from the top surface, such that a light path is formed between each light source and the window (38), with a portion of the light paths being parallel to the carrier (32), 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 (20), comprising a track area (22) for receiving touch input from a user, wherein the window is formed beneath the track area; and a touch sensor circuit (34) beneath the track area (22), wherein the touch sensitive circuit (34) comprises a touch sensor region on the top surface of the carrier (32); and a controller (70) adapted to control the light sources in dependence on a detected location of a touch input.
