METHOD FOR MEASURING DURATION OF INDIVIDUAL STEPS OF LEFT AND RIGHT FEET Russian patent published in 2021 - IPC G06F17/15 A61B5/103 

FIELD: computer technology.

SUBSTANCE: present invention relates to the field of computer technology. The result is achieved due to the fact that by means of an accelerometer and a microphone contained in a computing device, the acceleration and sound level are recorded when walking in a straight line, performed by the user for a predetermined time; two sequences of recorded data are formed and their subsequent joint processing is carried out by means of a computing device, and the sequences of recorded data are synchronously recorded readings of values from the accelerometer and microphone sensors; a two-dimensional correlation function of the signal from the vertical axis of the accelerometer and the reference step model is formed; the signal from the microphone of the computing device is processed to clarify the time coordinates corresponding to the detected local maxima of the two-dimensional correlation function; the sequences of collected data from the accelerometer and the microphone are superimposed on each other; on the basis of the superimposed data, the durations of individual steps are calculated as time intervals between adjacent boundaries.

EFFECT: increased accuracy of determining the durations of individual steps based on signals from the sensors of a mobile device by more accurately detecting the boundaries of steps in the time domain.
