Abstract

Cette invention se rapporte à un dispositif électronique, à son procédé de commande et à un serveur qui communique avec le dispositif électronique. Le dispositif électronique, son procédé de commande et le serveur qui communique avec le dispositif électronique comprennent : une unité d'affichage ; une unité de communication qui échange des données avec le serveur ; et une unité de commande destinée à afficher un second chemin sur l'unité d'affichage en recherchant le second chemin qui reflète un contenu lié au trafic collecté par l'intermédiaire d'au moins un autre terminal quand un événement est généré au cours d'un processus de guidage de chemin pour guider un premier chemin, le contenu lié au trafic étant obtenu à partir du serveur par l'intermédiaire de l'unité de communication et pouvant être affiché par rapport à la zone dans laquelle les premier et second chemins ne se chevauchent pas. La présente invention peut fournir un contenu lié au trafic et des chemins collectés par l'intermédiaire d'un autre terminal.
