Abstract

L'invention concerne un support d'affichage d'objet matériel, un système d'affichage d'objet matériel et un procédé de commande et un appareil associé. Le procédé de commande d'un système d'affichage d'objet matériel comprend les étapes consistant à : acquérir des informations d'opération tactile concernant un utilisateur ; générer des informations de commande de moteur électrique en fonction des informations d'opération tactile ; et envoyer les informations de commande de moteur électrique à un support d'affichage d'objet matériel, de façon à régler l'angle de photographie d'une caméra dans le support d'affichage d'objet matériel. Selon les modes de réalisation de la présente invention, au moyen de la solution technique, en commandant le mouvement d'une caméra et/ou d'un plateau tournant dans un support d'affichage d'objet matériel par un geste de commande tactile d'un utilisateur, puis en commandant l'angle de prise de vue de la caméra concernant un objet affiché, une photographie omnidirectionnelle et multi-angle de l'objet affiché dans le support d'affichage d'objet matériel peut être réalisée, améliorant ainsi l'effet de l'affichage d'objet matériel, et il n'est pas nécessaire que l'utilisateur se déplace sur un côté du support d'affichage d'objet matériel afin régler manuellement l'affichage d'objet matériel, de sorte que l'interactivité de l'affichage d'objet matériel soit améliorée.
