本文研究了人体的机械阻抗作为力和挠度知觉之间的潜在耦合参数。在5~1000赫兹频率范围内，测量了27名受试者指尖的力感觉阈值和29名受试者同一位置的机械阻抗。根据结果，拟合了阻抗模型，并计算了感知挠度的阈值。这些数据与其他研究小组已经公布的阈值进行了比较。结果表明，两个数据集都有很好的拟合度，从而证实了机械阻抗是这两个知觉维度之间的耦合参数。
This paper investigates the mechanical impedance of a human subject as a potential coupling parameter between force and deflection perception. Measurements of the force perception threshold of 27 subjects at the fingertip and the mechanical impedance of 29 subject at the same location in the frequency range of 5 ... 1000 Hz were conducted. From the results, a model for the impedance was fitted and thresholds for the perception of deflections were calculated. These were compared to already published thresholds from other research groups. The results show a good fit of both data sets, therefore confirming the mechanical impedance as coupling parameter between these two dimensions of perception.
