由于尺寸较小和重量轻的优势，已经研究了电刺激装置，以提供与虚拟物体有关的触觉反馈。电刺激装置可以直接激活感觉受体以产生反应力或触摸感。在当前的研究中，我们测试了一种诱导指尖电力感觉的新方法，呈现触觉反馈，旨在改变柔软，硬度和粘性感知。我们开发了一个3D虚拟现实系统，结合了手指捕获和电刺激设备。该系统可以提供视觉反馈和虚幻力的感觉，这些力是使用肌腱或阴极刺激通过前反射或向后扩张移动食指的。在演示中，参与者可以体验虚拟物体的柔软，硬度和粘性的感觉。
With the advantages of small size and light weight, electrical stimulation devices have been investigated for providing haptic feedback in relation to virtual objects. Electrical stimulation devices can directly activate sensory receptors to produce reaction force or touch sensations. In the current study, we tested a new method for inducing electrical force sensation in the fingertip, presenting haptic feedback designed to alter softness, hardness and stickiness perception. We developed a 3D virtual reality system combined with finger-motion capture and electrical stimulation devices. The system can provide visual feedback and the sensation of illusory force that moved the index finger by forward-flexion or backward-extension using tendon or cathodic stimulation. In the demo, participants can experience the sensation of softness, hardness and stickiness of a virtual object.
