令人愉快的刷牙疗法可能对患有自闭症、创伤和焦虑症的人有益。虽然研究监测刷牙速度，但手动传递刷子笔划会带来可变性。对人类刷牙物理的详细测量可能有助于了解这种变化以及随后对接收者感知愉悦感的影响。在这里，我们在一根刷子上安装了多轴力和位移传感器，以在 12 名参与者愉快地抚摸接受者的前臂时测量其物理特性。算法程序识别皮肤接触，并定义到达、中风、离开和中风之间的通话时间的四个阶段。扭矩大小（而不是力）被评估为最小化惯性噪音的指标，因为它记录了电刷弯曲和方向。总体而言，自然刷牙实验的结果表明力和速度值在 0.4 N 和 3-10cm/s 范围内，与之前的工作一致。然而，我们观察到刷子之间在速度、力、扭矩和笔划长度方面存在显着差异。经过进一步分析，扭矩和力测量值是相关的，但扭矩提供了与速度不同的信息。在评估接收者对初步案例研究中刷牙者个体差异的反应时，较高的愉悦感与较低的平均扭矩和较低的刷牙持续时间瞬时方差有关。扭矩大小似乎补充了速度对感知愉悦感的影响。
Pleasant brush therapies may benefit those with autism, trauma, and anxiety. While studies monitor brushing velocity, hand-delivery of brush strokes introduces variability. Detailed measurements of human-delivered brushing physics may help understand such variability and subsequent impact on receivers’ perceived pleasantness. Herein, we instrument a brush with multi-axis force and displacement sensors to measure their physics as 12 participants pleasantly stroke a receiver’s forearm. Algorithmic procedures identify skin contact, and define four stages of arrival, stroke, departure, and airtime between strokes. Torque magnitude, rather than force, is evaluated as a metric to minimize inertial noise, as it registers brush bend and orientation. Overall, the results of the naturally delivered brushing experiments indicate force and velocity values in the range of 0.4 N and 3-10cm/s, in alignment with prior work. However, we observe significant variance between brushers across velocity, force, torque, and brushstroke length. Upon further analysis, torque and force measures are correlated, yet torque provides distinct information from velocity. In evaluating the receiver’s response to individual differences between brushers of the preliminary case study, higher pleasantness is tied to lower mean torque, and lower instantaneous variance over the stroke duration. Torque magnitude appears to complement velocity’s influence on perceived pleasantness.
