FiDTouch: A 3D Wearable Haptic Display for the Finger Pad
- 用微型倒置德尔塔机器人精准传递接触与压力刺激
- 用户测试验证了静态空间接触和皮肤拉伸感知效果
- 适合虚拟现实、远程手术训练等高沉浸场景
指尖触觉设备已广泛应用于虚拟现实、医疗训练模拟和远程机器人操作等领域，显著提升了用户体验、培训效果和交互方式。本文提出FiDTouch，一种可穿戴的3D触觉显示装置，能向指腹提供接触、压力、碰撞、皮肤拉伸及振动触觉反馈。通过在结构设计中引入微型倒置德尔塔机器人，实现了对指腹表面精确且快速变化的动态刺激。通过两阶段用户研究评估了该装置在指腹上生成静态空间接触和皮肤拉伸刺激的感知性能。实测表明，该装置能精准提供触觉与力反馈，显著增强人机及人-机器人交互中的沉浸感与效率。
原文摘要 · Abstract (English)
The applications of fingertip haptic devices have spread to various fields from revolutionizing virtual reality and medical training simulations to facilitating remote robotic operations, proposing great potential for enhancing user experiences, improving training outcomes, and new forms of interaction. In this work, we present FiDTouch, a 3D wearable haptic device that delivers cutaneous stimuli to the finger pad, such as contact, pressure, encounter, skin stretch, and vibrotactile feedback. The application of a tiny inverted Delta robot in the mechanism design allows providing accurate contact and fast changing dynamic stimuli to the finger pad surface. The performance of the developed display was evaluated in a two-stage user study of the perception of static spatial contact stimuli and skin stretch stimuli generated on the finger pad. The proposed display, by providing users with precise touch and force stimuli, can enhance user immersion and efficiency in the fields of human-computer and human-robot interactions.
