Abstract: A system comprising an object; a computer device with a digital model containing a virtual object corresponding to the object; a position sensor for detecting the position of the object; and a communication means to transmit the position of the object to the computer device. The object is stretchable and the system is further provided with sensors for detecting the stretched condition of the object and with communication means to transmit said condition to the computer device. A system with actuators to modify the position and/or the stretched condition of the object and use of such systems for a collaborative complex problem-solving procedure in the context of urban planning.

Abstract: A system comprising a display provided with zones, a token, a proximity sensor for detecting the proximity of a token to one zone and a processor to register in a memory an association upon the detection of the proximity of the token to the zone. The association is logged as a set of data comprising the data of which a representation is made on the zone in the proximity of which the token has been brought. The processor is programmed to update a log file with the logged association. The processor performs an operation in accordance with the content of the log file.
