Although various indicators can be used for the comparison process, it is not limited. However, there is a problem if the correlation of time series data is obtained and the deviation is more than a certain value (correlation function is less than a certain value). It is also useful to evaluate that there is no problem if it is below a certain level (the correlation function is above a certain level).

  Note that a reference value recorded in advance in the reference value recording unit 2207 is used as a reference value serving as a reference for diagnosis. As is clear from the above description, the reference values include the above-described open-eye standing still position S21, closed-eye standing still position S22, fixation point gaze standing still position S23, and motion target of those who are considered to have no problem with the posture control function.
