Claim:
1. A movement supporting method comprising the steps of: recording, by at least one movement sensor attached to a user, a first sensor output signal when the user starts moving; transforming the first sensor output signal into a first autocorrection waveform by computing an autocorrection function of the first sensor output signal; determining a first movement tempo value of the user based on the first autocorrection waveform; setting, by at least one computer processor, a target tempo of an exercise performed by the user, wherein the target tempo of the exercise is set based, at least in part, on the first movement tempo value; recording, by the at least one movement sensor, a second sensor output signal during performance of the exercise by the user; transforming the second sensor output signal into a second autocorrection waveform by computing an autocorrection function of the second sensor output signal; determining, based on the second autocorrection waveform, a plurality of second movement tempo values of the user during performance of the exercise, wherein each of the plurality of second movement tempo values indicates a rate of physical movements performed by the user during a fixed time interval during performance of the exercise; determining, with the at least one computer processor, whether the plurality of second movement tempo values are outside of a target range that includes the target tempo for a predetermined period of time; and outputting a warning when it is determined that the plurality of second movement tempo values are outside of the target range for the predetermined period of time, wherein outputting a warning comprises outputting a first warning when it is determined that the plurality of second movement tempo values exceed the target range for the predetermined period of time and outputting a second warning when it is determined that the plurality of second movement tempo values fall below the target range for the predetermined period of time, wherein the first warning and the second warning are different.
