<p>The invention is a method and a system for detecting commands issued by a user of a given apparatus. Detection is performed in a 3-dimensional space around the apparatus and by touching directly on the apparatus. A sensor arrangement for detecting changes in electric fields generated by capacitive means enables detection of objects, e.g. a finger, in one or more proximity fields surrounding the apparatus, and by directly touching the apparatus. Detecting objects in a remote field of the apparatus is enabled by infrared means.</p><p>Typical applications are support of operation of multimedia apparatuses, AV systems, media players, and similar equipment. The invention has properties malting it suitable for mounting on printed circuit boards and improving the quality of the detection system such that user-supplied commands may be certainly and unambiguously detected, interpreted and executed as related functions in a given apparatus.
