Device for Assisting in the Navigation of a Person

A device for assisting in the navigation of a person, said device being fitted to the person, comprising:

• a computer (41) comprising in memory a mapping of the place (1) in which a path of the person is planned between a departure point (A) and an arrival point (B), and a location software;
• a human-machine interface (45) linked to the computer (41);
• a set of sensors (42) worn by the person and linked to the computer, the sensors delivering information about movements of the person and his position in said mapping;
• the location software (43) performing a processing of signals originating from the sensors (42) and from the human-machine interface (45), and performing a fusing of data provided by the mapping and the information arising from the sensors worn by the person and from the interface, and then calculating on the basis of these data the location of the person, the calculation of the path to be traveled is updated as a function of identified attained intermediate objectives of the path (A, B), these intermediate objectives being marked on said mapping.
