A basis of quality control on industrial products is to confirm that materials parts, assembly and processing and so on satisfy regulation. There are some cases depending on types of assembly processes that the result of certain process cannot be confirmed whether it satisfies regulation. For example, order to fasten some screws to fix a part is determined to guaranty accuracy to fox the part. However, in case of screwing order is not correct, the part is fixed. In this case, the accuracy is not guarantied. If accuracy is enough high accidentally, inspection on samples of assembled products cannot find the violation of screwing order. Therefore, we are now developing a system that monitors routine works using terrestrial magnetism sensors. In this system, a terrestrial magnetism sensor is attached into a worker to a tool, and the system judges whether certain routine work is correctly done by using output of the sensor. We have realized almost precise detection of wrong works, however, we could not identify which kind of wrong work is detected by our system without seeing worker’s motion. So grasping which kind of wrong works happened is depends on worker’s report on his/her work. Therefore, we added a video recording feature in our system. In this paper, we describe its design and implementation and simple evaluation result.
