Abstract

L'invention concerne un dispositif de notification de signal portable portant un dispositif d'alerte de proximité qui s'active lors de l'identification d'un avertisseur de recul à proximité d'un risque identifié. Lorsqu'un signal est reçu, un mouvement de vibration est communiqué au bracelet. Le signal peut être généré suite à l'identification d'un son d'une tonalité ou d'une fréquence identifiée utilisée par un avertisseur de recul d'un camion ou d'un autre équipement en mouvement. Lorsque la tonalité ou la fréquence se situe à un niveau de bruit identifié, le bracelet génère une alarme vibratoire tactile. L'invention va donc venir renforcer l'avertisseur sonore de recul présent sur l'équipement en mouvement grâce à des vibrations communiquées à un utilisateur, ce qui entraîne une meilleure perception des dangers potentiels par l'utilisateur lorsque celui-ci se trouve dans une zone de risque associée au véhicule en mouvement.
