Abstract

La présente invention se rapporte au domaine technique de la réalité virtuelle (VR) et concerne un procédé et un appareil permettant d'afficher une interface de VR, un dispositif et un support de stockage lisible. Le dispositif peut être un téléphone mobile, un ordinateur plat, un dispositif portable, un dispositif monté sur véhicule, un casque de VR, des lunettes de VR, et analogues. Le procédé consiste : à obtenir un premier contenu d'affichage en appelant un premier objet de support, le premier contenu d'affichage étant un contenu d'affichage d'une première application (app) ; à obtenir un second contenu d'affichage en appelant un second objet de support, le second contenu d'affichage étant un contenu d'affichage d'une seconde application ; à générer une interface de VR en fonction du premier contenu d'affichage et du second contenu d'affichage, l'interface de VR comprenant le premier contenu d'affichage et le second contenu d'affichage ; et à afficher l'interface de VR. Le procédé peut éviter une interruption d'affichage lorsque l'application est commutée.
