  • VR glasses use a head-mounted display device to close a person's vision and hearing to the outside world, and guide the user to create a feeling in a virtual environment.
  • the display principle is that the left and right eye screens respectively display the images of the left and right eyes, and the human eye obtains such a difference information and generates a stereoscopic effect in the mind.

  • the adjusted image is not quite compatible with the human eyeball. After all, the human body feels less accurate and easy to wear.

Abstract

La présente invention concerne un procédé de commande de lecture d'image claire et fluide basé sur des lunettes VR, consistant à : afficher clairement l'image à un œil humain au moyen de l'ajustement de la position relative de la lentille des lunettes VR et de l'œil humain, et rendre la lecture d'image plus fluide au moyen du traitement du nombre de trames d'images de lecture. La présente invention peut mettre en œuvre un ajustement autoadaptatif de lunettes VR en fonction de l'état des yeux d'un utilisateur, et assure une lecture d'images vidéo fluide, de sorte que les yeux de l'utilisateur sont moins sujets à la fatigue, ce qui protège les yeux de l'utilisateur et améliore l'expérience de l'utilisateur.
