Abstract

The embodiments of the application provide a head-mounted display device adjustment method and a head-mounted display device. The adjustment method includes the following steps: identifying the current head action of a user wearing a head-mounted display device according to the attitude data of the head-mounted display device; determining whether the current head action is a focal length adjustment indication action according to the corresponding relationship between head actions and action categories; and if the current head action is a focal length adjustment indication action, making an electromagnetic actuator in the head-mounted display device generate a magnetic field signal and drive a lens component and / or a display screen component in the head-mounted display device to move underthe action of the magnetic field signal. In the application, the electromagnetic actuator is combined with the head action of the user, which helps to improve the efficiency of focal length adjustment.

Description

technical field [0001] The present application relates to the field of virtual reality technology, and in particular to a method for adjusting a head-mounted display device and the head-mounted display device. Background technique [0002] With the continuous development of virtual reality (Virtual Reality, VR) technology, more and more head-mounted display devices have entered people's daily life. A head-mounted display device includes an electronic screen for displaying images and an optical lens for distortion correction between the human eye and the electronic screen. When the user wears the head-mounted display device to watch the image on the electronic screen through the optical lens, the head-mounted display device will use the optical principle to close the user's vision and hearing to the outside world, and guide the user to have a feeling of being in a virtual environment. [0003] In order to meet the vision needs of different users, physical knobs or buttons ar...
