Abstract: A control system of an interactive toy set that responds to network real-time communicating messages has at least two toys and two network computer devices connected to the toys, respectively. Each toy has a processor built in with a table of corresponding real-time communicating messages and control commands. Each computer device is built in with real-time communicating software and conversion software. Once the real-time communicating software starts running, one or several remote computer devices that are in communications with the local computer device are obtained by the conversion software. Communicating messages are then exchanged between the local and remote computer devices. The communicating messages are then sent to the toy. According to the table, the processor controls the toy to perform the corresponding motions. Therefore, the player can make the toy respond according to the communicating messages, increasing the fun of remote communications.
