1. A method for aiding emergency responders in retrieving a path, comprising:
receiving motion data from a first motion sensor registering motion of a first emergency responder of at least one emergency responder exploring an emergency scene;
compiling track data based on the motion data of the first motion sensor, wherein the track data represents a first track of the first emergency responder through the emergency scene;
calculating path data based on the track data, wherein the path data represents a path coinciding with at least a part of the first track; and
providing the path data to an actuator arranged for guiding an emergency responder of the at least one emergency responder along the path; wherein
calculating the path data comprises:
recognizing crossings in the track data for recognizing parallel tracks between crossings; and
selecting one of the parallel tracks for the path data; and
compiling the track data comprises:
obtaining a location and/or an orientation of the first motion sensor on a body of the first emergency responder and/or equipment carried by the first emergency responder;
obtaining a track width; and
establishing the track data based on the motion data, the track width, and the location and/or the orientation of the first motion sensor.
