Abstract
An input device for an electronic device includes a proximity detector and a light source. The light source transmits light to a sensing area, which is reflected back to the proximity detector in the presence of an object in the vicinity of the sensing area, such that the proximity detector can produce an output indicative of a distance of the object from the proximity detector to give rise to a control signal for controlling the device.
