在本文中，我们表明，一个简单的触觉设备可以准确地引导用户通过平面手部运动。该设备通过用户食指的指垫上的皮肤拉伸反馈来引导用户。在评估两种类型的刺激的角度匹配测试中，用户能够区分八个刺激方向，并以10度的精度将他们的手的运动与刺激方向相匹配。在两个运动引导测试中，触觉提示有效地引导用户的手臂运动通过他们可到达的工作空间的全部范围。实时校正反馈大大提高了用户的性能，使用户的平均手部运动保持在规定路径的12 mm内和指示方向的4度内。此外，该文件表明，参与者表现出扭曲的触觉感知反应，发现扭曲导致的反应方向偏差，但适当的触觉反馈可以纠正的效果。这种运动引导在人机交互中有应用，例如上肢康复。
In this paper, we show that a simple haptic device can accurately guide users through planar hand movements. The device guides the user through skin stretch feedback on the fingerpad of the user's index finger. In an angle matching test evaluating two types of stimuli, users are able to discriminate between eight stimulus directions and match the motion of their hand to the stimulus direction with 10 degree accuracy. In two motion guidance tests, haptic cues effectively guide users' arm motions through the full extent of their reachable workspace. Real-time corrective feedback greatly improves user performance, keeping average user hand motions within 12 mm of the prescribed path and within 4 degree of the indicated directions. Additionally, the paper shows that participants exhibit distorted haptic perceptual responses, finding that the distortion causes a response direction bias, but that appropriate haptic feedback can correct for the effect. Such motion guidance has applications in human-machine interaction, such as upper-extremity rehabilitation.
