Gesture-based computer control system applied to the interactive whiteboard

In the paper the gesture-based computer control system coupled with the dedicated touchless interactive whiteboard is presented. The system engineered enables a user to control any top-most computer application by using one or both hands gestures. First, a review of gesture recognition applications with a focus on methods and algorithms applied is given. Hardware and software solution of the system consisting of a PC, camera, multimedia projector and screen for projected images is presented. Image processing methods used and the fuzzy rule-based gesture recognition concept are described. The application called Interactive Whiteboard, enabling to draw shapes on a virtual whiteboard developed for use with the system is then presented. The functionality of the Interactive Whiteboard and the way of managing the contents with hand gestures is shown. Results of testing the system are also contained.
