Abstract:
Eye tracking has become a popular field of research recently. It is not only getting more
advanced but also giving rise to new research fields like eye tracking in neuro-architecture,
e-sports etc. This project is a small step towards the wide-open research area of eye
tracking. It has been developed with a vision to help the quadriplegic patients, who have
limited movement capacity of their body. Due to their restricted movement, they have
serious difficulties while working with computers and other electronic devices. Their needs
might not be fully satisfied by current assistive technology, so a sophisticated eye tracking
and on-screen pointing is required. With the help of this technology, physically disabled
people will be able to communicate and use digital platforms more easily and with greater
confidence thanks to a consistent, flexible, and intuitive interface. This technology aims to
improve the quality of life for people with physical disabilities and encourage their active
involvement in a variety of activities, such as social interactions, sports, education, and
entertainment, by providing increased accessibility and inclusivity. The motivation behind
developing an interactive system is to help people who have limited physical movement.
Currently available solutions are in some cases costly. Whereas the proposed system in this
research is more cost effective. This proposed system tracks the eye gaze using the webcam
of a computer. Then it analyzes and responds with the output that in which region the person
sitting in front of the camera is looking at. Taking input from the user’s eye movement, the
system moves the mouse on the screen. This study provides a landmark based machine
learning model that can track eye gaze and suggest designated message for the gaze. The
accuracy of the proposed system is around 90%. This system can be an easy to install and
more cost-effective solution to the patients suffering from physical disability. Hopefully
this system will provide a more user-friendly way to quadriplegic patients in terms of
communicating with the outside world.
