A navigator attempts safe navigation while keeping a good tension, and they are influenced by mental/physical workload in the navigational environment is always changes. We have been catching R-R interval, which response is good in physiological indices (e.g. respiration, skin temperature, pulse of finger), to evaluate the mental workload of them. The R-R interval represents the change of the mental workload; however, we will get the unwanted response. So, we need to clear the relationship between their conditions and the response of R-R interval. We have done that for low frequency components of the R-R interval, and for high frequency components is not yet. In this paper, we aim at high frequency components. We measure R-R interval of five kinds of posture and work, and analyze the frequency component using Fast Fourier Transform and Maximum Entropy Method.
