Self-efficacy, which is a belief to achieve a goal, is important for sufficient enhancement of physical ability of elderly people. For implementation of self-efficacy to assistive systems, it is necessary to subliminally change reference trajectories of the system within the range at which people cannot recognize the difference (just-noticeable difference: JND). This study clarified that elderly people have weaker position sense rather than young people when they are moved passively in relatively fast speed. New reference hip trajectories are computed to gradually extend hip flexion of human standing-up motion based on the measured JND.
