Abstract: By simulating real working environment,a method for creating graphical user interface of next generation is proposed.First,an extendable 3D interactive workplace is built,and 3D objects carrying physical properties such as mass,volume,color and friction coefficient are imported.Then,the techniques of collision detection and rigid body dynamics are adopted.Finally,a corresponding prototype called user-centered desktop navigation system(UCDN)is developed.The evaluation results indicate that the method shows high usability as well as strong interest to users,and it makes a valuable investigation to the next generation graphical user interface.
