Modeling the User

In the preceding chapter the frequency-dependency of mechanoreceptors relevant for haptic perception. has been discussed, i.e. the amplitude of a mechanical oscillation is perceived with varying intensity for different frequencies. Additionally, it has been shown that the dynamics of haptic perception results in demanding requirements for the design of technical systems. Consequently, a good mechanical design has to consider the user in his or her mechanical properties. The first part of the fourth chapter deals with the discussion of the user as a mechanical load on the haptic device. The corresponding model is split into two independent elements depending on the frequency range of the oscillation. In the second part of the chapter a model of frequency dependent perception for highdynamic oscillations is presented. The chapter ends with examples of the models’ applications as well as a summary.
