Method and device for measuring the progress of a moving person

A device for displaying progress of a moving person, comprising:

• a display unit;
• and
• a measuring unit that comprises an acceleration sensor, an analysis and diagnostic unit, and a magnetometer,
• wherein the acceleration sensor is configured to measure acceleration values of cyclic motion of locomotion of the moving person,
• wherein the magnetometer is configured to obtain compass readings of the moving person,
• wherein the analysis and diagnostic unit is configured to calculate step data as a function of step-cycle-specific acceleration stage characteristic accelerations a+ and braking stage characteristic accelerations a− obtained from acceleration values measured by the acceleration sensor during a step cycle,
• wherein the analysis and diagnostic unit is configured to determine the step data as a step-cycle-specific acceleration stage characteristic acceleration a+ as a mean value of a digitally filtered acceleration sensor signal aout over a time selected during a positive half-cycle of the step cycle, and a braking stage characteristic acceleration a− as a mean value of a digitally filtered acceleration sensor signal aout over a time selected during a negative half-cycle of the step cycle,
• wherein the analysis and diagnostic unit is configured to determine a traveled route of the moving person by means of the step data and the compass readings,
• wherein the display unit is configured to display the traveled route of the moving person, and to guide the moving person via step by step navigation using the traveled route.
