1. An apparatus comprising: an output interface; one or more processors; and the one or more memories and the computer program code configured to, with the one or more processors, cause the apparatus at least to: obtain a sensor event created on the basis of sensor data generated by one or more Sensors; determine relevance of the sensor event; and if the relevance of the sensor event fulfils a predetermined relevance condition, output, with the output interface, the sensor event according to its determined relevance, wherein the one or more memories and the computer program code are further configured to, with the one or more processors, cause the apparatus further to determine the relevance of the sensor event by the following: adjust the relevance of the sensor event for a specific person on the basis of a responsibility condition such that the relevance of the sensor event for the specific person is increased, the nearer the sensor event is to a responsibility of the specific person, and the relevance of the sensor event is decreased, the farer the sensor event is to the responsibility of the specific person.
