Abstract

To research the relation between joint impedance and signal dependent noise which opposes each other at the end-point error, we performed 2 types of experiments. Their results suggested that muscle activity increased as demanded accuracy increases, and the relation between duration and accuracy (Fitts' law) varied by conscious control of muscle activity.
