Abstract: A device for storing a path followed by a bearer, notably to guide a person. The device includes a set of sensors with which the bearer can be equipped, capable of at least giving a measurement of distance covered by the bearer and a measurement of change of heading made by the person; and means of processing the measurements performed by the set of sensors, said processing means creating and storing a metric graph representing the path followed by the bearer, said graph being formed by a set of nodes, a node consisting of at least one event detected by the set of sensors at a point on the path and of a link indicating a measurement of distance and of heading relative to the preceding node covered by the bearer, the first node of the graph being the starting point of the path.
