Preliminary Experiment for Navigation on Tactile Display Using DC Motor

摘要

In this paper, as a preliminary experiment for walking navigation, conduct experiments of the pseudo force sense using four different waveforms when holding the DC motor with three fingers. In addition, two types of the DC motors with different rotation per minute or RPM and torque, are used to examine an impact of those properties of motors on the pseudo force sense. As a result, it is found that people would feel the pseudo force sense in the direction of the weak rotational acceleration. And There can also be a tendency for people to perceive the pseudo force more easily in the extending direction of the wrist. Moreover, by comparing results from two type of motors with different RPM and torques, it is found that the motor with higher RPM and torque would cause people to feel easily pseudo force.
