A system comprises an analyzing unit configured for receiving a sensor signal indicating a use of a tool and for analyzing the sensor signal for a sensor signal characteristic. The system comprises a database having stored thereon at least one predetermined sensor signal characteristic and an associated signal information. The system comprises a classification unit configured for determining a correspondence between the sensor signal characteristic and the predetermined sensor signal characteristic. The system comprises an interface configured for outputting, to a user, the signal information associated with the predetermined sensor signal characteristic, and for receiving an input signal indicating at least a match or a mismatch of the use of the tool with the predetermined sensor signal characteristic. The classification unit is configured for adapting the database based on the input signal for a subsequent sensor signal.
