Interactive projector screen with hand detection using gestures

There are very few interfacing technologies to manipulate real-time behavior for operating computer systems. During a presentation, it is inconvenient to control the computer and simultaneously explain the topic. There are several alternatives like speech recognition, laser based gloves but these techniques are less portable and have less accuracy. Our system, interactive wall display, allows you to use hand gestures to control OS on the projected screen. We have developed an effective human-computer interface for a virtual mouse system in a projector-camera configuration without any hardware requirement. To experience our project only one camera source is required to detect the user's hand.
