Abstract
Control of a device including aiming a pointing device comprising a camera and a source of invisible light in the direction of an object associated with the device to be controlled, upon which object a number of retroreflective marker elements are positioned, which reflect at least a part of the invisible light emitted by the light source back to the pointing device; generating a first image of a target area aimed at by the pointing device whereby the light source is inactive; generating a second image of the target area aimed at by the pointing device whereby, invisible light is emitted by the light source in the direction of pointing; processing the target area images to determine the presence of retroreflective marker elements; using information pertaining to the retroreflective marker elements to identify the device to be controlled and/or to determine a control signal for the identified device.
