Design and Implementation of Human-Computer Interaction System Based on Real-Time Tracking of the Shoot Point from the Light Pen

摘要：

In recent years, virtual-reality technology has developed rapidly and much attention has been paid on how to move the model in the virtual environment in real time. Traditional human-computer interaction is realized by the keyboard and the mouse of computer, but they can not be moved freely. The light pen can be carried more conveniently, so this paper puts forward to move the model in the virtual environment by the light pen. The experiment results shown make clear that automatic tracking of the shoot point under dynamic and complex background can be realized by the improved Camshift algorithm. Moving the model in the virtual environment by the light pen is also more stable. Therefore, we can say that real-time tracking of the shoot point from the light pen based on the improved method has important practical values in human-computer interaction.
