A gear rack and a gear are provided between the left lens barrel and the right lens barrel, and the gear rack is made to be occluded with the gear. A magnet is fixed at a preset position, and a magnetic induction intensity of the magnet set based on a relative position relationship between the left lens barrel and the right lens barrel in the VR device is detected by means of a Hall sensor. A distance between the Hall sensor and the magnet is calculated according to the magnetic induction intensity. Relative movement data between the gear rack and the gear is determined based on the distance between the Hall sensor and the magnet, and then a distance between the left lens barrel and the right lens barrel is determined according to the relative movement data, and the distance between the left lens barrel and the right lens barrel is determined as a pupil distance between both eyes of a user, so that targeted image can be output based on the pupil distance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"VR system and positioning and tracking method of VR system","description":"A position detection device of a VR device is provided.
