Abstract

This study presents a lightweight, wearable fingertip haptic device that provides physics-based haptic feedback for dexterous manipulation in virtual environments without hindering real-world interactions. The device, designed with thin strings and actuators attached to the fingernails, ensures minimal weight (1.55 g per finger) and preserves finger flexibility. Integrating the software with a physics engine renders multiple types of haptic feedback (grip force, collision, and sliding vibration feedback). We evaluated the device's performance in pressure perception, slip feedback, typical dexterous manipulation tasks, and daily operations, and we gathered user experience through subjective assessments. Our results show that participants could perceive and respond to pressure and vibration feedback. Through dexterous manipulation experiments, we further demonstrated that these minimal haptic cues significantly improved virtual task efficiency, showcasing how lightweight haptic feedback can enhance manipulation performance without complex mechanisms. The device's ability to preserve tactile sensations and minimize hindrance to real-world operations is a key advantage over glove-type haptic devices. This research offers a potential solution for designing haptic interfaces that balance lightweight construction, haptic feedback for dexterous manipulation, and daily wearability.

轻量级指甲触觉装置：无阻碍指垫力和振动反馈增强虚拟灵巧操作。

本研究提出了一种轻量级、可穿戴的指尖触觉设备，该设备为虚拟环境中的灵巧操作提供基于物理的触觉反馈，而不会妨碍现实世界的交互。该装置由细绳和驱动器连接在指甲上，确保了最小的重量（每根手指1.55克），并保持了手指的灵活性。将软件与物理引擎集成可以呈现多种类型的触觉反馈（握力、碰撞和滑动振动反馈）。我们评估了设备在压力感知、滑动反馈、典型灵巧操作任务和日常操作方面的表现，并通过主观评估收集用户体验。我们的研究结果表明，参与者可以感知和响应压力和振动反馈。通过灵巧操作实验，我们进一步证明了这些最小的触觉线索显著提高了虚拟任务效率，展示了轻量级的触觉反馈如何在没有复杂机制的情况下提高操作性能。与手套式触觉设备相比，该设备能够保持触觉感觉并最大限度地减少对实际操作的阻碍，这是一个关键优势。这项研究为设计触觉界面提供了一种潜在的解决方案，可以平衡轻量化结构、灵巧操作的触觉反馈和日常可穿戴性。

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
