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
An input device for detecting input with respect to a reference plane. The input device includes one or more light sensors positioned to sense light at an acute angle with respect to the reference plane and for generating a signal indicative of sensed light, and a circuit responsive to said light sensor for determining a position of an object with respect to the reference plane.

9. 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 (10, 11)

12. A non-contact device for the translating the movement of an object into data comprising:
-
one or more light sources;
one or more light sensors, aligned to sense light reflected from said object, as said object is illuminated by said one or more light sources; and
a circuit, for calculating the relative position of said object with respect to one or more reference points, based on said sensed, reflected light. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
