Recently the development of touch gesture in mobile devices has been faced with a generalization problem which is very dependent on the number of multi-touch points. In this paper we propose a touch gesture recognition method which is independent from variation of touch shape and the number of touch points, and it could be considered superior than those of Microsoft's window7. This method recognizes the multi-touch gestures using central moments of touch area, distances and angles between touch points, and paths of each points. Additionally, the shapes of each touch, ellipsoidal shape and area information, are used in our method to make the gesture more sensitive. We have evaluated our method on our hand-made tabletop display system and the result has shown that the proposed method is surely more elaborated and intuitive than previous methods.
