This paper presents a new-type application that interlinks the none-digital world with digital world based on the photo
sensors. Nowadays, Tangible User Interfaces (TUIs) have emerged as a novel interface pattern. It combines the users'
knowledge of physical interaction and digital information together. Meanwhile, the interactive tabletops with optical
sensors show great potential in the field of entertainment, display and education. The system fuses the tangible user
interface and tabletop interaction into an organic whole. With low consumption and high brightness, it achieves the
identification of different physical entities.
