将动觉反馈接地到用户的手可以增加触觉设备的便携性和可穿戴性。然而，不同的手接地位置对用户的触觉感知的影响是未知的。在这封信中，我们调查了三个不同的手接地位置的手，食指近节指骨，食指中节指骨上的触觉感知使用一种新设计的可穿戴触觉设备的影响。该新型装置可以在两个方向上向用户的食指提供动觉反馈：沿着手指轴和手指的屈曲-伸展运动方向。我们测量用户的触觉感知每个接地位置通过心理物理实验的两个反馈方向。结果表明，在所研究的位置，接地在近节指骨有一个较小的平均只是明显的差异，两个反馈方向，表明更敏感的触觉感知。触觉反馈的真实性，基于用户评级，是最高的接地在中间指骨反馈沿着手指轴，并在近端指骨的反馈在屈曲-伸展方向。用户将触觉反馈识别为最舒适的，其中在手背处接地以用于沿着手指轴的反馈，并且在近端指骨处接地以用于在屈曲-伸展方向上的反馈。这些研究结果表明，接地位置的选择对用户的触觉感知和定性体验有显着的影响。研究结果为设计下一代可穿戴手接地动觉设备提供了见解，以在虚拟现实和遥控机器人应用中实现更好的触觉性能和用户体验。
Grounding of kinesthetic feedback against a user's hand can increase the portability and wearability of a haptic device. However, the effects of different hand-grounding locations on haptic perception of a user are unknown. In this letter, we investigate the effects of three different hand-grounding locations—back of the hand, proximal phalanx of the index finger, and middle phalanx of the index finger—on haptic perception using a newly designed wearable haptic device. The novel device can provide kinesthetic feedback to the user's index finger in two directions: along the finger-axis and in the finger's flexion-extension movement direction. We measure users’ haptic perception for each grounding location through a psychophysical experiment for each of the two feedback directions. Results show that among the studied locations, grounding at proximal phalanx has a smaller average just noticeable difference for both feedback directions, indicating a more sensitive haptic perception. The realism of the haptic feedback, based on user ratings, was the highest with grounding at the middle phalanx for feedback along the finger axis, and at the proximal phalanx for feedback in the flexion-extension direction. Users identified the haptic feedback as most comfortable with grounding at the back of the hand for feedback along the finger axis and at the proximal phalanx for feedback in the flexion-extension direction. These findings show that the choice of grounding location has a significant impact on the user's haptic perception and qualitative experience. The results provide insights for designing next-generation wearable hand-grounded kinesthetic devices to achieve better haptic performance and user experience in virtual reality and teleoperated robotic applications.
