The invention discloses a VR video playing system based on plot selection. When the playing system is adopted to play videos, a user controls the videos to be subjected to fast forward, fast reverse,and clipping through gestures, when bifurcated plots exist during video playing, the user is prompted to select the plots, a camera collects gesture images of the user, an image recognition module recognizes gestures of the user in the gesture images collected by the camera and transmits the gestures to a main controller, and the main controller judges a control instruction corresponding to the user gestures, and plays the corresponding video plots according to the control instruction. When the user falls asleep by accident in the watching process and an eye state identification module detectsthat the user turns to an eye closing state from an eye opening state, timekeeping is conducted, and the playing system is closed after a preset time.
