In ubiquitous computing environments, many computers should be controlled in cooperation to support human daily-life. We pick up a dance performance that performers wear a large amount of LEDs to combine body expression and lighting effects. In such situation, there is a problem that failure frequently occurs caused by dance movements. In the environment involving hundreds of computers, it costs much time and effort to check where failures have occurred. To solve this problem, we propose a system for identifying the position of the failure easily by checking the status of communication among computers. In addition, we implemented a fault diagnostic system that can provide a series of flows for detecting the failure, guessing why the failure occurred and taking a measure. Furthermore, we actually used our system into LED dance performances, conducted an evaluative experiment, and confirmed its usefulness.
