Summary: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.
