众所周知，我们的触觉是四种类型的机械感受器活动的结果，每种机械感受器对不同类型的皮肤变形做出反应;压力，低频振动，高频振动和剪切拉伸。如果我们能有选择地激活这些感受器，我们就能联合收割机并呈现任何类型的触觉。这一办法已得到研究，但尚未完全实现。在我们的研究中，我们开发了FinGAR（用于增强现实的手指手套），其中我们结合了电刺激和机械刺激来选择性地刺激这四个通道，从而实现高保真触觉。电极阵列的电刺激呈现压力和低频振动，空间分辨率高;直流电机的机械刺激呈现高频振动和整个手指的剪切变形。此外，FinGAR重量轻，机构简单，易于佩戴，并且不会干扰手指的自然运动，所有这些都是通用虚拟现实系统所必需的。
It is known that our touch sensation is a result of activities of four types of mechanoreceptors, each of which responds to different types of skin deformation; pressure, low frequency vibration, high frequency vibration, and shear stretch. If we could selectively activate these receptors, we could combine and present any types of tactile sensation. This approach has been studied but not fully achieved. In our study, we developed FinGAR (Finger Glove for Augmented Reality), in which we combined electrical and mechanical stimulation to selectively stimulate these four channels and thus to achieve high-fidelity tactile sensation. The electrical stimulation with array of electrodes presents pressure and low frequency vibration with high spatial resolution, while the mechanical stimulation with DC motor presents high frequency vibration and shear deformation of the whole finger. Furthermore, FinGAR is lightweight, simple in mechanism, easy to wear, and does not disturb the natural movement of the finger, all of which are necessary for general-purpose virtual reality system.
