The title of the Patent is ‘System for creating an environment’. The specification is in French and there was an agreed translation.

This is Figure 2 which shows an embodiment of the invention:

Projectors 310 are in the ceiling of the room 900. A projection cone 611 emitted by each projector creates a partial image 610 on the floor 910 of the room. The partial images from the projectors combine to create an overall image, as shown a karting track 911. A ‘mobile element’ 200 as shown is a kart located on a projected track and for simplicity I will assume that the mobile element of the invention is a kart. There may be more than one kart.

There is a locating system comprising sensors 110 in the ceiling, each of which has a ‘capture zone’ 121, corresponding to the zone perceived by the sensor. The area of the floor within a capture zone is the capture surface 120 of the sensor. Preferably the capture surfaces cover the whole image 600 so that the kart is always visible to the locating system. An administrator uses a management device 500 to select the form of track and the type of game to be played. A server (not shown) receives this input and determines the information to be sent to the projection system and to the kart (or karts). In effect, the server coordinates the projection system, the locating system and the information sent to the kart.

Each kart has an emitter (not shown in Figure 2) so that its position may be detected by the locating system. The specification states (omitting reference numbers):

The electromagnetic radiation is detected by the sensor, which allows each sensor to perceive karts present in its capture zone. Where the preferred infrared lamp or lamps are used by the emitter on the kart:

An FPGA is a field-programmable gate array, a type of integrated circuit that can be reprogrammed after manufacture which allows flexibility of application by the user.
