Abstract

La présente invention concerne un procédé de partage de données. Lorsqu'un premier dispositif électronique (tel qu'une tablette informatique) peut reconnaître, au moyen d'un radar à ondes millimétriques, que le mouvement d'un deuxième dispositif électronique (tel qu'un téléphone mobile) est un mouvement spécifique, le partage de données entre le premier dispositif électronique et le deuxième dispositif électronique est déclenché, de sorte que des étapes de fonctionnement pour partager des données entre le premier dispositif électronique et le deuxième dispositif électronique puissent être simplifiées, et qu'un processus de transmission de fichier puisse être raccourci.
