2H1-1 A Study on the Force Adjustment by Non-Dominant Hand

要旨

The purpose of this study is to examine the differences in the characteristics between the dominant hand and non-dominant in the hand operation which needs adjustment control. In this study, we compared the performance of the force adjustment task between with dominant hand and the non-dominant hand and re-examined the product design. We also examined the mental workload between the above two conditions, that are the tasks with the dominant hand and with the non-dominant hand. As a result, it was cleared that both the right-handed subject and the strong-left-handed subject could adjust with less muscle strength in case they used the dominant hand. And it was also cleared that they output more force than necessary in case they used the non-dominant hand. Further, it could be found the remarkable differences in the result of performance, EMG, and mental workload (NASA-TLX) between with the dominant hand and with the non-dominant hand no matter whether the subject was right-handed or left-handed. On the other hand, in case the subject was the weak-left-handed, it could not be found the distinguished differences in the result of performance, EMG, and mental workload (NASA-TLX) between with the dominant hand and with the non-dominant hand.
