Abstract
A method of a monitoring and remote controlling real world have been described by using a VRML/Java based virtual reality space which contains multimedia elements, intended for the development of a ubiquitous monitoring system. The focuses are given on the improvements for currently used, static virtual reality spaces to be more capable of an interactive function through which users can bilaterally monitor or control the real world. The monitoring is realized by reflecting sensing data from sensors which were placed in the real space onto a virtual reality space. Remote control can be realized by sending commands to actuators through the 3-D space. Additionally, the virtual reality space has been created as a Web page. So that the multiple users can access the system at the same time. The developed system has shown the availability for such applications as robot navigation, management of buildings and monitoring of factories and environments. In this paper, the construction method of the new technique of the real space monitoring and its operation experiment are described which can put in view a full-scall ubiquitous environment. The extendibility and possibility for monitoring are also described which could provide essential ubiquitous environments.
