説明

<p>Light touch contact (LTC) proposed by Jeka in 1997 can reduce unstability in human standing by the user lightly touching a curtain or similar with fingertips. However, the potential contribution of LTC to human posture control strategy has not yet been elucidated. This paper proposes a novel human standing control model designed to reproduce the influence of LTC on sensory reweighting which is a principle of control strategy for human standing posture. The approach allows us to represent time-series changes in sensory weights caused by LTC and express body sway in a standing state. Simulation using the proposed model indicated its capacity to reproduce human sway more accurately than a previous model, and experimental results suggested that sensory reweighting was influential in standing attitude control.</p>
