Playing is the direct reflection of children??s playful nature. Games can not only attract children to participate in activities, but also encourage children to cooperate in activities. Therefore, this study attempts to introduce game elements into children??s tangible interactive narrative system to enrich children??s “storytelling” behaviors and processes. The game structure model of MDA (Mechanics, Dynamics, Aesthetics) in gamification design is introduced to provide design strategies and guidance for children??s tangible interactive narrative system, and the three key modules of game elements, game mechanism and game experience are substituted into the gamification design strategies of the children??s tangible interactive narrative system. Through the guidance of MDA game structure model for system construction, the relevant research cases are analyzed, and the gamification design strategies in children??s tangible interactive narrative system are put forward.
