Studies on dynamic touch have indicated that humans can estimate the length of a rod held in one hand simply by wielding it, without any visual information. Traditionally, these types of studies have held that proprioception is important for perceiving the moment of inertia of the rod, but this has not been demonstrated experimentally. In the present paper, we focused on joint acceleration and torque as physical values that approximate proprioception by introducing dynamics-based mechanics. In the experiments, the acceleration of the swinging of the rod was controlled. Since the acceleration and the torque both varied with time, their peak values were adopted as representative values. No correlation was observed between the angular acceleration and the perceived rod length. However, a strong correlation was found between joint torque and the perceived length. This indicates that humans perceive rod length through joint torque, which approximates proprioception.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
