Pedometer having automatic step length adjustment, method for operating a pedometer and application of said pedometer

摘要

A pedometer for determining the length of a route traveled on foot includes an acceleration sensor for ascertaining a number of steps as well as a pressure sensor for ascertaining a change in geographic elevation, and an evaluation unit being configured to adapt the step length to the measured average elevation change per step.

1. A pedometer, comprising:
an acceleration sensor adapted to detect a number of steps on the basis of acceleration signals of the acceleration sensor; a pressure sensor adapted to detect an elevation change on the basis of pressure signals of the pressure sensor; and an evaluation unit adapted to determine, by a predefined step length, a length of a route traveled; wherein the evaluation unit is adapted to use a variable step length as a function of a measured average elevation change per step, in order to determine the length of the route traveled; and wherein for a measured average elevation change per step of zero, the variable step length has a maximum value corresponding to the predefined step length, and the variable step length becomes increasingly shorter as an absolute value of the measured average elevation change per step becomes greater.
