The purpose of the study is to develop a self-learnable "system for self-checking movement-implementing body mechanics", which is, for example, used by nursing course students. In this paper, the method, for attaching GonioMeters and an angle sensor to a body, is improved and the usability of the system is improved. The usefulness of the system is discussed by measurement experiments, in which, a triangle corner setting is performed as a nursing task.
