When we learn such complicated movements as sports and dances, we imitate the ideal movements in most cases. To learn these movements effectively, it is necessary to detect the movement to be improved from photos and videos and to reproduce the movements in corrected ways. It is also required for learners to evaluate their own learning achievements. To solve this problem, the authors have focused their attentions on the transmission of information instead of power and energy: the information-intensive concept can be achieved by introducing an active haptic scheme where users voluntarily moved their muscles, after accepting triggers from the actuators, and the concept was referred to as a restrained small-power based motion instruction in this paper. Under the novel concept, a prototype of a 2-link 1-DOF rotational elbow joint interface was developed for teaching extension-flexion operations of forearms. A potential of the novel instruction concept was confirmed from the viewpoint of motion reproducibility and necessary torques.
