Abstract: This dissertation focuses on the development of a simple and cost effective interactive whiteboard for teaching purposes. The application is developed using only two digital webcams as external devices and thus it avoids the need for a costly touch sensitive whiteboards, SMART boards, or wiimote camera and infra red pen. Specifically it describes a system which identifies the actions performed on the computer displayed whiteboard by processing the image frames taken by two webcams which are placed on both sides of the whiteboard screen. These images are analysed and processed inside the computer and changes are made on the computer desktop as a response to the actions on the whiteboard. This allows direct human-interaction with the whiteboard and thus avoids the need to use the computer mouse during the lecture or presentation.
