In summary, the implementation manner is beneficial to realizing the effects that under the condition that the viewing effect is not affected, the display scene is judged based on the vibration value of the VR headset 100 sensed by the acceleration sensor 101, so that the resolution of the shared image data is automatically reduced, the influence of image data transmission and display on the cruising ability of the battery of the VR headset 100 is weakened, and the power consumption of the VR headset 100 and the display device is reduced.
