指尖触觉显示(FHD)是华盛顿大学开发的一种五杆机构，用于与操作者的指尖进行触觉交互。该两自由度机构经过计算机优化，以适应具有高度运动各向同性的人类手指弯曲/伸展的工作空间。采用无摩擦平板线圈执行器的直接驱动确保了驱动系统中的低扭矩波动、惯性和静态摩擦，以实现高保真的触觉渲染。本文描述了对位置传感布置、I/O硬件和软件以及热建模的重新设计，以提高性能，并在多指触觉显示器中堆叠了四个用于食指、中指、无名指和小指的设备。给出了初步性能评估的部分结果。有前景的应用有望包括对医务人员的触诊培训，使参观者能够“触摸”艺术的博物馆展览，以及心理物理学研究：探索人类触摸感知的极限。
The fingertip haptic display (FHD) is a five bar mechanism developed at the University of Washington for haptic interaction with the fingertip of the operator. The two-degree-of-freedom mechanism was computer optimized to accommodate the workspace of the human finger inflexion/extension with a high degree of kinematic isotropy. Direct drive with frictionless flat-coil actuators ensures low torque ripple, inertia, and static friction in the actuation system for high fidelity haptic rendering. This paper describes a redesign of the position sensing arrangement, I/O hardware and software as well as thermal modelling to improve performance and stack four devices for use with index, middle, ring and little finger in a multifinger haptic display. Some results of the initial performance evaluation are given. Promising applications are expected to include palpation training for medical personnel, museum displays enabling the visitor to "touch" art, as well as psychophysics research: exploring the limits of human touch perception.
