Detection of Iris Movement by Estimating Sclera Size and Sync it with the Caster Wheel of a Wheelchair

Interacting with real or virtual objects with help of a human eye is gaining popularity. The paper presents a robust method to detect eyeball movement and how we can use it to move a wheelchair in direction of the line of sight of the user. Through a web camera, we continuously capture the photographs of either the left or the right eye. Since the target eye is stationary with respect to the camera, so we can do an accurate and fast detection of any movement detected in the eye region of the photograph. We can then send this information to the wheelchair connected to the computer through the serial port.
