本文试图验证人类受试者可以在没有视觉信息的情况下沿着超声波产生的虚拟路径移动手。从开始到结束(“目标”)的路径是通过切换超声焦点来呈现的。焦点的移动会在手上产生振动触觉刺激，用户会将其视为一条线。用户可以通过跟踪这条线将手移动到球门。在该方法中，用户主动跟踪路径，因此不需要反馈手部位置。在实验中，我们验证了参与者可以将手移动到球门，偏差小于50 mm。此外，手的轨迹与曲线路径之间的平均偏差小于40 mm。因此，我们得出结论，用户在感知它的同时沿着路径移动他们的手。
This paper attempts to verify that human subjects can move a hand along a virtual path produced by ultrasound without visual information. The path, from start to finish (the `goal'), is presented by switching ultrasound focal points. The movement of focal points produces vibrotactile stimuli on the hand, and users perceive it as a line. The users can move their hand to the goal by tracing this line. With our method, users actively trace the path, therefore no feedback of hand position is necessary. In the experiment, we verified that the participants can move their hand to the goal with a deviation of less than 50 mm. Also, the average deviation between the trajectory of the hand and a curved path is less than 40 mm. Thus, we concluded that users move their hand along the path while perceiving it.
