Abstract

Skin-slip provides crucial cues about the interaction state and surface properties. Currently, most skin-slip devices focus on two-dimensional tactile slip display and have limitations when displaying surface properties like bumps and contours. In this article, a wearable fingertip device with a simple, effective, and low-cost design for three-dimensional skin-slip display is proposed. Continuous multi-directional skin-slip and normal indentation are combined to convey the sensation of three-dimensional geometric properties in virtual reality during active finger exploration. The device has a tactile belt, a five-bar mechanism, and four motors. Cooperating with the angle-mapping strategy, two micro DC motors are used to transmit continuous multi-directional skin-slip. Two servo motors are used to drive the five-bar mechanism to provide normal indentation. The characteristics of the device were obtained through the bench tests. Three experiments were designed and sequentially conducted to evaluate the performance of the device in three-dimensional surface exploration. The experimental results suggested that this device could effectively transmit continuous multi-directional skin-slip sensations, convey different bumps, and display surface contours.

设计和评估用于三维皮肤滑动显示的可穿戴指尖设备。

皮肤滑动提供了有关交互状态和表面特性的重要线索。目前，大多数皮肤滑动装置侧重于二维触觉滑动显示，在显示凹凸和轮廓等表面属性时存在局限性。本文提出了一种设计简单、高效、低成本的可穿戴指尖设备，用于三维皮肤滑动显示。连续多向皮肤滑动和法线压痕相结合，可在手指主动探索时在虚拟现实中传达三维几何属性的感觉。该装置有一个触觉带、一个五杆机构和四个电机。配合角度映射策略，两个微型直流电机用于传递连续的多方向皮肤滑动。两个伺服电机用于驱动五杆机构，以提供正常的压痕。通过台架试验获得了该装置的特性。设计并依次进行了三次实验，以评估该装置在三维表面探测中的性能。实验结果表明，该装置可以有效地传递连续的多方向皮肤滑动感觉，传递不同的凹凸感，并显示表面轮廓。

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.
