• A MEASUREMENT OF THE EXERTED FORCE CHARACTERISTICS OF ELDERLY : DOMINANT HAND FOR DESIGNING JOYSTICK CONTROLLER

抄録

To design a suitable hand-controlled joystick, it is necessary to study the sensory motor characteristics of the force and torque exerted by the hand. In the last paper, we reported the characteristics of the young male and female subjects. To compare the characteristics between young subjects and elderly subjects, the exerted torque data of elderly subjects were measured on actual operating postures. This paper focuses on the following points. 1) Comparisons of the minimum torque differences exerted by the dominant hand between the subject's groups 2) A verification of Weber's law, namely the ratio of the minimum torque to the prior load torque. To measure the torque exerted by a hand, a joystick capable of sensing six axes of force and torque was prepared, and the experiment was performed with 8 male and 8 female (48-66 years old) subjects. The results showed that, a) there is no significant difference about the minimum torque between the elder male and the elder female subjects. And the minimum torques of the elderly is larger than the young's. b) Weber's ratio close to approximately 0.1-0.2 as the prior load torque increases. These results suggest that the minimum torque differs depending on the age difference, and that Weber's law is applicable.
