Abstract

La présente demande divulgue un procédé et un appareil de commande de paramètre, un dispositif visiocasque et un support de stockage, qui se rapportent au domaine technique des dispositifs électroniques. Le procédé est appliqué au dispositif visiocasque qui comprend une caméra et un écran d'affichage. Le procédé comprend les étapes suivantes consistant à : lorsque le dispositif visiocasque est dans un état de port, acquérir, au moyen d'une caméra, une image comprenant un œil d'un porteur en tant que première image ; acquérir, sur la base de la première image, une image du regard du porteur en tant que deuxième image ; acquérir une image affichée par l'écran d'affichage en tant que troisième image ; et commander le paramètre de l'écran d'affichage sur la base de la deuxième image et de la troisième image. La présente invention commande le paramètre de l'écran d'affichage par comparaison de l'image du regard du porteur avec l'image affichée par le dispositif visiocasque, ce qui permet d'améliorer la précision de la commande de paramètres et d'améliorer l'expérience de l'utilisateur.
