Abstract: The primary goal of this study is to explore the impacts of visual feedback gain and the force varying rate on the continuously fluctuating isometric force production. Twelve recruited participants have been instructed to complete the handgrip tasks that require the participant to control his or her grip force level to track a moving target bar which is proportional to the real-time force production. Two visual feedback gain levels and two force varying rates have been tested. The results show that high visual feedback gain and force varying rate will lead to larger errors of force production.
