VR interaction method and system based on position change

The invention provides a VR interaction method based on position change, and the method comprises the steps: enabling a VR system to generate relative motion through a preset posture, capturing a relative position point of the relative motion through a sensor, determining the relative displacement of the relative motion according to the relative position point, judging whether the relative displacement is contained in a preset interaction threshold interval or not based on the state of the VR system, and if the relative displacement is contained in the interaction threshold interval, obtaining an interaction instruction corresponding to the preset posture, so that corresponding quick interaction operation is executed according to the interaction instruction to complete VR interaction. Therefore, the VR interaction can be completed without clicking a system menu, the user can easily complete various shortcut operations while experiencing wonderful contents, and the user can customize common contents, movies, t
