本文提出了一种新型的触觉可穿戴设备的设计，能够创建一个连续的横向运动的前臂上的错觉，模仿社会触摸中常用的抚摸手势。该装置由一个带有线性热塑性气动致动器阵列的织物套筒组成。致动器依次充气和放气，使用电子压力调节器仔细控制每个致动器的充气量。手臂上的压力行波产生了横向运动的错觉，即使没有物理横向运动发生。我们在人体研究中评估该设备，以确定最佳的驱动参数，创造最连续和愉快的感觉。研究结果表明，较短的充气时间会产生更连续和愉悦的感觉，但充气期间的压力变化不会影响连续性和愉悦感。
This paper presents the design of a novel haptic wearable device capable of creating the illusion of a continuous lateral motion on the forearm to mimic a stroking gesture commonly used in social touch. The device is composed of a fabric sleeve with a linear array of thermoplastic pneumatic actuators. The actuators are sequentially inflated and deflated, carefully controlling the amount of inflation of each actuator using an electronic pressure regulator. The travelling wave of pressure up the arm creates the illusion of lateral motion, even though no physical lateral motion occurs. We evaluate the device in a human-subject study to determine the optimal actuation parameters that create the most continuous and pleasant sensation. The results of the study indicate that short inflation times create a more continuous and pleasant sensation, but the pressure change during inflation does not affect continuity and pleasantness.
