A Motion Analysis System for Pointing and Calling Considering Safety Checks for Soldering Work

In Japan, pointing and calling are carried out to improve the safety, reduce human errors and prevent accidents. Via pointing and calling concept the safety is improved by pointing to the work object or tool and voicing the situation in order to predict the accidents during the work. In factories, soldering is part of the handicraft industry and one of the career options for people with disabilities. During soldering skill, it is necessary to memorize and repeat the same work, which takes a long time. Also, there are human errors caused by accidents and lack of safety checks or experience. In addition, ensuring worker safety requires continuous monitoring of worker motion, which is a significant burden for instructors. In this paper, we propose a motion analysis system for pointing and calling. The proposed system uses a depth camera to capture images of workers during pointing and calling. Also, the proposed system considers beforehand safety checks for soldering operations to prevent accidents and injuries. The experimental results of the pointing orientation show that the proposed system is effective for safety checks and can support beginners and people with disabilities to continue soldering work safely.
