Summary:With the emergence of multi-touch interactive display platforms, large size multi-touch platform is developed greatly. Cooperation and conflict is the problem for multi-user operation on huge screen. In this paper, the problem of multi-user's cooperation is studied. Based on the FTIR multi-touch interactive surface a solution scheme for multi-user cooperative touch interaction is proposed, in which a camera is placed above the interactive desktop for hand detection, tracking and ownership definition. So hand tracking of different users is key technique in the proposed scheme. Camshift method is used for hands of multi-users tracking in this paper, in which Opencv and C++ are applied to implement the function above.
