Automatic description system of the motion procedure and trajectories of hands and eye-gaze for analysis of assembly work

Abstract

In this research, we propose charts of description for analysis of assembly work and the sensing system which has facility of automatic description. Charts of description consist of "motion procedure chart" and "trajectory chart for hands and eye-gaze", "motion procedure chart" can describe kinds of motion and it time, "trajectory chart for hands and eye-gaze" can describe trajectories of hands and eye-gaze. The sensing.system describes the motion based on mutual interferences of hands and objects. It also describes the eye-gaze estimated by the device which is a work cap equipped with two laser pointers. We evaluated the accuracy of description. As a result, we confirmed that the description success rate of the motion procedure is 83.4% on average. And we confirmed that the error in trajectories of hands is within 20mm beside the error in the trajectories of eye-gaze is within 13.4mm on average.
