1. A system for classifying the usage of a consumer appliance, the system comprising:
the consumer appliance comprising a sensor unit including at least one of an inertial sensor, a gyroscope, a magnetometer, and a force sensor, the sensor unit being structured to determine at least one usage data at successive time instants and to provide a temporally successive sequence of usage data relating to a motion of the consumer appliance or a force acting thereon during a usage session; and
an analyzing device comprising a processor and structured to classify the usage of the consumer appliance with respect to at least one set of at least two usage classes relating to different usage properties, wherein the analyzing device assembles a temporally successive sequence of input tuples of usage data relating to a predetermined time period of the usage session, each of the input tuples comprising at least one element representing the usage data at the respective time instant and for inputting the sequence of input tuples into at least one artificial neural network that is arranged to output at least one output tuple that comprises a number of elements in accordance with the number of usage classes, each element of the output tuple representing a prediction value that the usage of the consumer appliance at the given time instant relates to a respective usage class, and wherein the analyzing device determines a single usage class answer for the time period based on the sequence of output tuples.
