Abstract

Humans have the ability to identify external physical properties because skilled object manipulation requires knowledge, or internal models, of object dynamics relating to applied force or movement. The accuracy of identification depends on those of the input and output signal to the object : motor command from brain as the input and information from multiple sensory modalities as the output. In this paper, control strategies of isometric contraction by hand are investigated. Subjects are asked to generate constant levels of force under two conditions : force production tasks a) by self scaling without visual feedback and b) with visual feed back of reference force levels. The results show subjective assessments of force are larger than objective one, and it is indicated that the variability is composed of signal dependent noise and error of human intention. It is also demonstrated that visual feedback information has an important role of generating accurate reference force level.
