Abstract
The arrangement detects an object that is irradiated by waves in the invisible spectral range. Infrared illumination is preferably employed in order to recognize an object on a display projected onto an arbitrary surface that is displayed for the user in the visible spectral range and to be able to track the movement of this object. User interfaces produced by a computer can thus be projected onto an arbitrary background. Touch-free inputs can ensue on these user interfaces by moving the hand or with some other input unit, whereby the triggering of an action is coupled to a dwell for a prescribable time over a field linked to a control characteristic.
