ABSTRACT:
A system provides a user with proper information about a target exhibition object among many exhibition objects in exhibition facilities according to a user's request. The system has a database system for storing information about exhibition objects, a host computer, and at least one terminal. The host computer has a host transmitter/receiver unit and retrieves information from the database system according to the identification code of a given exhibition object. Each of the exhibition objects has a communication unit that returns an identification code in response to a request signal. The terminal has a terminal transmitter/receiver unit for communicating with the host computer, an operation switch for generating the request signal according to a user's operation, an object communication unit for transmitting the request signal to a target exhibition object and receiving an identification code therefrom, an information output unit for providing the user with information about the target, and a control unit. The control unit transmits the request signal toward a target exhibition object through the object communication unit in response to a user's operation of the operation switch to select a target exhibition object from the exhibition objects, receives an identification code from the target through the object communication unit, transmits the identification code to the host computer through the terminal transmitter/receiver unit, receives information about the target from the host computer through the terminal transmitter/receiver unit, and provides the user with the information through the information output unit. The host computer retrieves the information about the target from the database system according to the identification code and transmits the information to the terminal through the host transmitter/receiver unit.
