INFORMATION SERVICE SYSTEM

摘要

PROBLEM TO BE SOLVED: To obtain an information service system that can quickly serve a huge amount of information to an operator under the control of a host computer without imposing much load onto a communication between the host computer and a terminal and the operator at the terminal side. SOLUTION: A terminal 3 of an operator side controller A worn by an operator and a host computer 11 of a commander side controller B store a plurality of the same display object data files. The host computer 11 generates a display command signal of image information corresponding to a specific display object data file by an operation of the commander side entry device. A commander side display device 13 displays the image information by the processing of the specific display object data file stored in the host computer 11 in response to the display command signal. Transmitting the display command signal to the terminal 3 via a communication means processes the specific display object data file stored in the terminal 3 and an operator side display device 2 displays the image information.
