论文摘要
本文提出了一种新型的触觉设备Deltafinger，旨在通过引导用户的手指使用可穿戴的三角洲机构来提供与虚拟物体的互动力。开发的界面能够将3D力量向量传递到用户的食指的指尖，从而使虚拟现实（VR）环境复杂渲染。开发的设备能够在垂直投影中产生高达1.8 n的动力学反馈，而水平投影的0.9 n则可以在不限制其余手指的运动自由度中产生0.9 N。实验结果表明，在使用Deltafinger（平均力矢量误差为0.6 rad）的力量感知方面有足够的精度。提出的设备可能会应用于有视力问题的人的VR通信，医学和导航。
This paper presents a novel haptic device DeltaFinger designed to deliver the force of interaction with virtual objects by guiding user's finger with wearable delta mechanism. The developed interface is capable to deliver 3D force vector to the fingertip of the index finger of the user, allowing complex rendering of virtual reality (VR) environment. The developed device is able to produce the kinesthetic feedback up to 1.8 N in vertical projection and 0.9 N in horizontal projection without restricting the motion freedom of of the remaining fingers. The experimental results showed a sufficient precision in perception of force vector with DeltaFinger (mean force vector error of 0.6 rad). The proposed device potentially can be applied to VR communications, medicine, and navigation of the people with vision problems.
