Research in the field of Human Computer Interaction (HCI) has been spectacularly successful and has fundamentally changed computing. In the proposed system, a real time computer vision based interaction prototype is designed where hand gestures are used to control the movement of a mouse pointer using colour markers. This paper aims at providing a unique approach for a more reliable interaction between the user and the system. To avoid the limitations of personal computer, an embedded system
