Abstract: Head tracking technology is an alternative to the mouse that allows the person control over the movement of the cursor by using only the movement of his head.
We present a simple prototype system for real time tracking of a human head. This system uses a simple yet a effective Face tracking algorithm. The general requirements of a real time tracking algorithm – it should be computationally inexpensive, should possess the ability to perform in different environments and should be able to start and initialize itself with minimum knowledge about the environment, are well addressed by the elliptical head tracking algorithm.
The objective of this project is to create an alternative user interface uniquely using real time video of the user’s face captured using an off-the-shelf web-camera.
The position of the head is tracked and converted into two-dimensional coordinates on a computer screen; additionally, it is intended to enable the recognition of a deliberate blink in order that this could be considered as a command from a user.
