Abstract

L'invention concerne un procédé de positionnement en intérieur comprenant : l'émission par un premier dispositif d'un premier signal à un second dispositif dans une première zone, le premier signal étant utilisé afin de déclencher l'émission par le second dispositif d'un signal de balise, et le signal de balise transportant un identifiant du second dispositif ; la détection par le premier dispositif d'une intensité de signal du signal de balise émis par le second dispositif ; et la détermination par le premier dispositif, en fonction de l'intensité de signal du signal de balise et de l'identifiant transporté par le signal de balise, d'un emplacement du premier dispositif par rapport au second dispositif. Le procédé utilise, en fonction d'un service domestique intelligent et d'une caractéristique d'environnement domestique, des appareils domestiques intelligents existants afin de réaliser, au moyen d'une commande logicielle et d'un algorithme, une fonction de positionnement en intérieur par rapport à un utilisateur sans déploiement d'une station de base ou augmentation des coûts, ce qui permet un grand potentiel de services domestiques intelligents et de nouveaux services intelligents.
