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.
