The invention discloses a scene interaction system and an interaction method. The scene interaction method is based on a scene interaction system, the scene interaction system comprises a signal collector, a signal processor, a content server and a displayer which are connected in sequence, the signal collector comprises a camera, and the method comprises the steps of using the camera for collecting continuous image signals to obtain interaction signals corresponding to the camera to be recognized; processing the interaction signal by using a signal processor to obtain interaction parameter data; and outputting the corresponding interaction content to the display according to the interaction parameter data by using the content server. By means of the mode, the interactive signals can be recognized, different feedbacks can be given according to different interactive signals, a user is stimulated to actively watch advertisements in an interesting interactive mode, and therefore the moreeffective advertising effect is obtained.
