速度変化知覚における視覚と触覚の影響

抄録

To instruct motions effectively, the authors have been studying how the effects of visual and/or haptics affect motion learning performances. They prepared a 2-D stroke motion of which velocity changes occurred on a predetermined trajectory: the trajectory where just the external rotation on shoulder worked was taken as an example of the 2-D stroke motions. It was examined whether subjects can perceive the change or not. Six types of instruction modes which are combinations of visual and/or haptics were compared for examining the perception characteristic. The performance of sensations were evaluated by measuring these velocity changes of threshold. In addition, the decisive factors for noticing the velocity changes were examined among the sensations such as the hand moving velocity, the muscular force, the contact force on finger-pads.
