Abstract

La présente demande concerne un procédé d'affichage en mosaïque, un dispositif électronique et un système. Le procédé comprend les étapes suivantes : un premier dispositif électronique affiche une première interface, la première interface étant une interface d'affichage d'une première application ; le premier dispositif électronique détecte une première entrée d'un utilisateur lors de l'affichage de la première interface, la première entrée étant une opération de démarrage de la seconde application ; en réponse à la première entrée, le premier dispositif électronique envoie au second dispositif électronique des informations d'image correspondant à une interface d'affichage de la seconde application ; en réponse à la réception des informations d'image correspondant à l'interface d'affichage de la seconde application, le second dispositif électronique affiche l'interface d'affichage de la seconde application. Selon des modes de réalisation de la présente demande, un utilisateur peut afficher de multiples applications sur de multiples dispositifs sans commutation de va-et-vient entre des applications, de sorte que l'expérience d'utilisateur soit améliorée.
