Abstract: A method for adjusting a strap of a VR device is provided and includes a method for tightening the strap. The method for tightening the strap includes obtaining, by tightening trigger, a tightening trigger signal; controlling, by PCB, a driver to drive a transmission component according to the tightening trigger signal to drive first and second straps to be tightened synchronously; obtaining, by pressure sensor, a pressure value of a preset part; and when the pressure value reaches a first preset value, controlling, by PCB, the driver to stop driving the transmission component according to a first pressure sensor signal, such that first and second straps are synchronously tightened to an appropriate position. The method automatically adjusts the tightness of straps, reducing user's operation processes and making it convenient and faster for the user to wear the VR device. The method can ensure moderate tightness for all user head shapes.
