ABSTRACT:
Method of transmitting signals between communication stations via a network, in which a central control station is adapted to transmit a picture of a virtually real ambience to each connected station. In the picture, connected stations are represented by objects which can be displaced by the user of the corresponding station. Other stations such as information sources are represented by stationary objects in the form of buildings. As soon as objects touch or overlap each other, an actual communication connection (for example a telephone conversation, a database consult, a transaction) is established between the corresponding stations. A "chat box" application is also provided, with the particular property that the extent of interaction between conversation partners is dependent on the mutual distance between their corresponding objects in the picture.
