A method and apparatus for reconstructing the behavior of an individual which provides: a detection operation, comprising recording monitoring signals using a detection apparatus carried by the subject; a mapping operation, comprising recording monitoring signals in an environment in which the behavior of the subject is to be reconstructed and the monitoring signals are to be associated with a map of the environment; an operation of reconstructing the behavior, comprising taking on as positions, over time, points on the map in which the monitoring signals recorded in the detection operation correspond to the monitoring signals recorded in the mapping operation.
