Basic frequency analysis on period fluctuations of rhythms produced by humans for their enjoyment

It is necessary to examine comfortable vibrations and swinging motions used in the development of a human-machine interface. Although the present study was limited to the rocking motion of a rocking chair, it was confirmed that the waveform of a swinging motion used as a type of stimulation, the per...

Next, the features of a swinging motion produced by a person for their enjoyment were examined.
