Abstract: An apparatus, method for lens barrel distance adjustment, device and computer medium are provided. The method includes: obtaining an eye image of a user; determining a pupillary distance of the user based on the eye image; obtaining a first output voltage determined by a hall sensor; in response to that the first output voltage indicates that an absolute value of a difference value between a distance between left and right lens barrels of a head-mounted device and the pupillary distance of the user is greater than a predetermined threshold, sending a control instruction corresponding to the difference value to an adjustment circuit, causing the adjustment circuit to adjust a distance between the left and right lens barrels based on the control instruction. The hall sensor and the adjustment circuit are provided on the head-mounted device.

Abstract: The present disclosure provides an extended reality device and a control method thereof. The extended reality device includes: a front part and a rear part; the front part comprising: a display module, configured to display extended reality image; the rear part comprising: a system controller connected to the display module and configured to control operation of the display module; a battery connected to the system controller and configured to supply power to each electrical device. Through the above solution, transferring the system controller and the battery to the rear part setting, so that the weight of the front part of the extended reality device is significantly reduced, the thickness of the front part is significantly reduced, the weight of the rear part and the front part can be balanced, there is no bias when user wears the extended reality device, which improves the user's wearing comfort.
