<p>The present disclosure relates to an improved input device and associated method. In particular an input device for a device is provided. The input 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. A method of controlling a device is also provided. The method uses an input device including a proximity detector and a light source. The method comprises the step of: transmitting light from a light source to a sensing area; receiving at the proximity detector light reflected by an object in the vicinity of the sensing area; deriving an output indicative of a distance of the object from the proximity detector; and providing a control signal based on the output to the device.</p> |
