Abstract:
The invention relates to composing a lighting atmosphere from an abstract description for example a lighting atmosphere specified in XML, wherein the lighting atmosphere is generated by several lighting devices, by automatically rendering the desired lighting atmosphere from the abstract description. The abstract description describes the type of light with certain lighting parameters desired at certain semantic locations at certain semantic times. This abstract atmosphere description is automatically transferred to a specific instance of a lighting system (14, 16, 18). The invention has the main advantage that it allows to create light scenes and lighting atmospheres at a high level of abstraction without requiring the definition of a lighting atmosphere or scene by setting the intensity, color, etc. for single lighting units or devices which can be very time consuming and cumbersome, particularly with large and complex lighting systems comprising many lighting devices.
Abstract:
The invention relates to an arrangement for wireless interaction by a user (3) with objects (8a-8d). The user can select one of the objects (8a-8d) with a pointing device (5), whereupon a transmitter (2) transmits a directed beam (7) of communication signals to a receiver (9a) connected to the object. The receiver is able in this way to recognize the fact that it has been selected by the user (3) and to perform appropriate actions. On a semi-transparent display device (5), the user (3) can see the real objects and, at the same time, additional information (6) inserted by a data-processing device (1).
