Abstract

L'invention concerne un système de projection dynamique guidé par le déplacement d'une personne qui met en oeuvre un dispositif de projection constitué d'un capteur de position, une unité de projection d'images, vidéo ou similaire, une unité centrale, un ensemble réflecteur et une unité de traitement qui capture, de manière itérative, le déplacement d'une ou de plusieurs personnes dans une zone concrète, traite ces informations et projette sur le sol une image, une animation, une vidéo ou similaires à des fins publicitaires, touristiques ou de diffusion de l'information en général qui se déplace également avec la personne en mouvement, rendant la projection facilement visible.
