METHOD, DATA STRUCTURE, AND EXECUTION SHELL FOR ENABLING POSITION-INDEPENDENT AND POSITION-TRANSMISSION INTERACTION BETWEEN PROGRAM AND USER

摘要

PROBLEM TO BE SOLVED: To obtain a system which enables input and output between a user and a program without the need to continuously obtain information regarding other presence positions by inspecting the state of the program so as to confirm the state of the program and interacting with the program according to the program state. SOLUTION: In either of cases of a moving user or a user interacting with a moving program, a request for the program state is initialized. Thereby, the current position of the program is determined and the current position of the user is made usable without the necessity of one of entities changing positions. Namely, the user 602 at a position P sends a movement script 302 out to a communication network 108 covering the position P, a position Q, and a position R. An agent server 104a is processed at the position Q. An agent server 104b and a web server 106 are processed at the position R.
