自我效能感是一种实现目标的信念，对老年人身体能力的充分增强具有重要意义。为了对辅助系统实施自我效能感，有必要在人们无法识别差异的范围内潜意识地改变系统的参照轨迹(仅可注意的差异：JND)。本研究明确了当老年人以相对较快的速度被动移动时，他们的位置意识要弱于年轻人。根据测量的JND计算新的参考髋关节轨迹，以逐渐延长人类站立运动的髋关节屈曲。
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.
