众所周知，当受到不对称振动时，人类会体验到类似于特定方向上的拉力感觉的动觉错觉。在我们之前的研究中，我们开发了一种可以施加平移力和扭矩来引发这种错觉的设备。虚幻的平移力可能会引起上肢的伸展运动，而施加的扭矩可能会引起手腕的屈伸运动。在本研究中，我们通过实验验证了是否可以诱导这些运动。结果证实，该装置在平移力和扭矩的施加之间切换时能够引导上肢，成功率为94.3%。结果表明，扭矩应用可以作为用户直观确定运动方向的提示。
It is known that humans experience a kinesthetic illusion similar to a pulling sensation in a particular direction, when subjected to asymmetric vibrations. In our previous study, we developed a device that can apply a translational force and a torque to induce this illusion. The illusory translational force might induce a reaching motion of the upper limb, and the applied torque might induce a flexion–extension motion of the wrist. In the present study, we experimentally verified whether these motions can be induced. The results confirmed that the device could guide the upper limb with a success rate of 94.3% when switching between the application of the translational force and the torque. The results suggested that torque application could be a cue for the user to determine the movement direction intuitively.
