Sensor-based Tracking of Variable Locomotion

Abstract

The invention relates to a method, device and system for the sensor-based tracking of a variable locomotion, and, in particular, to a method, device and system for acceleration-sensor based measurement of the highly erratic movement of a team sports player. The method comprises continuously measuring acceleration values corresponding to the locomotion of a person. For a single step of the person, a type of locomotion is determined by analyzing a temporal sequence of acceleration values of a portion of the acceleration values corresponding to the single step. Further, a swing time and at least one characterizing acceleration value are determined from the acceleration values for the single step and the step length is determined based on the type of locomotion, the swing time and the at least one characterizing acceleration value.
