Le module de palier (10) comprend un boîtier intermédiaire (12). Une cavité de réception (126) est formée dans le boîtier intermédiaire (12). Chaque module optique (20) peut être disposé de façon mobile dans la cavité de réception (126), et comprend un écran d'affichage (24) et un élément optique (26). L'écran d'affichage (24) est utilisé pour afficher une image. Le composant optique (26) est utilisé pour projeter l'image et/ou la lumière à l'extérieur du dispositif portable (100) aux yeux d'un porteur du dispositif portable (100). Le processeur (30) est utilisé pour traiter une entrée du porteur et émettre un signal de commande de distance pupillaire. Le moyen de réglage de distance pupillaire (40) est utilisé pour commander, en fonction du signal de commande de distance pupillaire, les deux modules optiques (20) pour qu'ils soient proches ou éloignés l'un de l'autre.
