System for tracking and recording movements, method using the system, mobile communication device

The present disclosure provides a system for tracking and recording movements of a mobile communication device, the method using the system, and the mobile communication device. The mobile communication device communicates sensor signals to the system, wherein the sensor signals are indicative of motion associated with activities to which the mobile communication device is exposed by its user. The sensor signals are pre-classified to generate the intermediate data, where the intermediate data is processed in one or more processors to generate indications of likely activities associated with the sensor signals, and an aggregate of the indications is computed to provide an analysis of activities associated with the sensor signals. The system analyses sensor signals to classify them into one or more temporal zones and determines a most likely activity type associated with a given temporal zone. The information indicating most likely activity types is sent to the mobile communication device.
