Claim One:
1. A mobility normalizing apparatus comprising a recording unit containing a plurality of reference waveform data sets, and a processing unit; wherein the processing unit: when externally acquired mobility measurement data is unit time sequence data, defines the measurement data as data to be corrected; when externally acquired mobility measurement data is a plurality of two-dimensional data sets associated with time information and measured values, interpolates these two-dimensional data sets to create the data to be corrected, which is unit time sequence data; reads the plurality of reference waveform data sets from the recording unit, and determines a plurality of warping functions converting the data to be corrected to the respective plurality of reference waveform data sets, and a DTW distance associated with each warping function; evaluates a minimum value of the plurality of DTW distances, and determines the warping function associated with the determined minimum DTW distance; determines a slope and an intercept of a straight line approximating the determined warping function; and corrects the data to be corrected using a linear function specified by the slope and the intercept.
