Description

ABSTRACT

The eyeball tracking system is an assistant system for the patients who are not able to do the voluntary work of daily life. To communicate to the real world eyeball tracking will be useful. Patients who can control their eyes can communicate with people in the real world. In this project, we are proposing one algorithm to identify and track the eyeball of our eye. Real-time data is captured via a webcam that transfers data serially to the system of Matlab.   Then a sequential image processing scheme will segment the iris of the eye and calculate the center there one control signal will be generated with the help of the reference axis. Then we can track the eyes with help of the signals.


INTRODUCTION

Communication between humans is among the greatest tool that they used to maintain their sustenance in this world. Apart from several languages constituting words that are evolved since the beginning of mankind, a universally known non-verbal expression still holds a noticeable weight in the eyes of humans. It is a common observation that the human eyes suffice the need to express thousands of words that convey huge emotions and feelings. In spite of this, there are cases when humans suffer from a disease that makes them incapable of moving any part of their body except their eyes. At that stage, eye movement is very critical in order for the patient to communicate with the real world and its surroundings.  Researchers working in the field of neuroscience utilize eye movement to read how human visual information processes. Clinicians in the field of psychology, psychiatry, and psycholinguistics, use eye-tracking systems for collecting data discretely and accurately. On-screen vision studies are conducted in the field of ophthalmology, furthering our understanding of the human eye and help developing new approaches for the diagnosis of disorders.


EXISTING SYSTEM

Previously we are using a feature matching algorithm to identify the eye in the plane. But those things will not work accurately while tracking the eyes. The algorithm which we are using in the existing system is better to identify the eyeball in the system by using a webcam but we cant track accurate objects sometimes it will not work exactly. Here we are going with a proposed algorithm for tracking the system


PROPOSED METHOD

Particularly in the proposed system, we are using the viola Jones algorithm to track the eyes. The algorithm will work as well as identification and tracking of the object with the same features which we had given in the database system. Mainly it will concentrate on how to extract the feature from a face in a real-time environment.
