As there is great advancement in the technology in recent years, there has been much improvement in various fields of computing such as Human Computer Interface (HCI), Computer Vision and Perceptual User Interface (PUI). Input to the computers has sensed information about physical properties of user, places, or things. For example, computer mouse operates by motion imparted by userâ€™s hand. Many active researchers have been working on finding an alternative solution to control computer mouse like by using finger, eye, hand/palm, marked gloves etc. These all techniques may not be suitable to physically disabled people. This paper introduces how head motion of user can be used to control the mouse cursor. A way to create an application which replaces the input device mouse by using face of the user is proposed. Since face/head is primary part of human body. We introduce a face detecting system which precisely record the motion parameters from video at real-time. According to the head movement the cursor is navigated on computer screen. The mouse clicks are performed only if the user does not move cursor for specified time. This method thus ignores the use of other facial features which are difficult to track under certain conditions. For example, in eye tracking if the user is wearing spectacles it becomes difficult for camera to track the movement of eyes in low light condition. This method can be considered as an alternative way of controlling mouse for users with hand disability and can also be used for motion control games and simulation.
