Using domain specific language for large screen game interaction

High-resolution display provides the advantage to video games by making gaming experience more realistic. Wall-size display extends the viewing experience of playing game to the entire visible zone with the immersive display experience. In this paper, we propose a new Domain Specific Language for wall-size game interaction naming it SDGi. This new programming language translates tracking signal of a spatial pointer into pointing input that are native to game operating systems. Motion of the illuminated pointer is used to mirror conventional mouse input to such a Single Display Groupware, thus eliminating the need for any extra or expensive hardware or a new software toolkit. Furthermore, the grammar of this domain specific language can be customized to create user defined pointer motions in 3D space so that all common pointing input can be simulated from using a pointer-based interaction to wall-size display.
