A Physics-Based Augmented Reality Jenga Stacking Game

In this paper, we present a cross-platform environment in which handheld and desktop-computer users can collaborate with each other in a shared scene to accomplish physically realistic experiences during the course of interaction. In realizing the system, we: 1) exploit client/server architecture to connect user devices, where the server is responsible for maintaining and managing the virtual objects shared by users, 2) build the distributed scene graph structure according to X3D specification for presenting 3D computer graphics, 3) use mobile phones as tangible input object to provide an intuitive interaction interface, 4) design a natural hand interface which enables users to directly manipulate virtual object using their bare hands. To demonstrate the effectiveness of the system, we developed Jeng AR, a simulation of the well-known tower building game.
