Method and device for detecting an object in an area radiated by waves in the invisible spectral range
First Claim
1. A system for detection of an object in an area irradiated by waves in an invisible spectral range, the system comprising:
- a projector configured such that a video image is projectable onto the area;
a device for emitting waves in the invisible spectral range configured such that the area is substantially illuminated;
a reception device configured such that the reception device registers the irradiated area, the reception device being specifically balanced for an invisible spectral range corresponding to the waves; and
a computer configured with a recognition algorithm, whereby the object irradiated by the emitted waves is detected using the recognition algorithm.

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.

11. A method for detecting an object in an area, the method comprising the steps of:
-
generating a video image having at least one field with a function available thereto in the area by a computer, the video image being projected onto a predetermined area;
moving the object into the predetermined area;
irradiating the area by waves whose wavelength lies in the invisible spectral range in order to detect the object;
using a reception device specifically balanced for the invisible spectral range corresponding to the waves to detect the object; and
triggering a function of a field by the object in that the object dwells in the field for a predetermined time. - View Dependent Claims (12, 13, 14)
