Efficiency Group Interaction Between Participants and Large Display

In recent years there has been an increasing interest in human-computer interaction research in large display systems. We contribute with a design of efficient group interaction technique and application to a large display by using optical technology to track the markers on users' hands. Participants were asked to execute predefined interaction actions based on the contents of the application screen. With the help of well-designed interaction processes and algorithms, our system can receive response signals of multiple users and then trigger corresponding actions in real-time. Moreover, we designed a performance experiment to evaluate the recognition and response results from practical application. The experiment results demonstrate that, although integrating group interaction into large display system, this framework can effectively support user's participation in large display.
