Abstract: The present invention relates to a method for estimating the value of the angle of the direction of motion or of the walk of a person who carries a device capable of measuring the basic quantities related to his/her own inertia such as a common smartphone. The device is capable of measuring for example acceleration and angular rotation and to determine its orientation relative to Magnetic North. The estimation method in question is particularly suitable for estimating the direction angle of the individual's motion regardless of how the individual carries the device able to measure the main inertial quantities and consequently this method solves the problem of the determination of the relative attitude between the reference system of the carried device and the user reference system that moves within a generic absolute reference system.

Abstract: Described is a process for reconstructing the movement of an individual who walks inside a space and who carries a device equipped with inertial sensors and a virtual representation (M) of the space. The process comprises: —an acquisition step of a first reference position (Pr1) and by choice: a first reference direction (vr1) associated with the first reference position (Pr1) or a second reference position (Pr2); —a detection step which comprises detecting, by means of the inertial sensors, a direction of movement for each step made by the individual; —a reconstruction step which comprises forming a trajectory (100) of the path of the individual, as a sequence of vectors (V1, V2, Vm); —an estimation step.

Abstract: 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.
