Abstract
The present disclosure provides a virtual reality device, a lens barrel positional state detection method and apparatus therefor, and a medium. The device comprises: a lens barrel module, a magnet, a magnetic sensor, and a main controller, wherein one of the magnet and the magnetic sensor is embedded on a lens barrel housing of the lens barrel module, and the other one is fixed at a corresponding preset position of the lens barrel module; wherein the main controller controls the lens barrel module to move and detects an output electrical signal of the magnetic sensor when the lens barrel module moves so as to determine a positional state of the lens barrel module.
