Abstract— Eye gaze tracking method is useful for physically disable people with loco-motor disabilities who cannot able to do their daily activities due to their disability. First important task is to find out the gaze point of eye then communicate this gaze point for motion of an object. Here controlled object is used as wheelchair the eye gaze movement. In Proposed system eye movement is detect by head mounted camera, output from camera will be process in Matlab to find gaze point the corresponding control signal send to motor driving circuit which control the movement of wheelchair according to eye movement of person.
encephalograph (EEG) [2],for measuring bio-potential Search coil can be used. The search coil output can be used as input sources to computer for handicap person. Limitations of this method is that is cost and give poor gaze direction accuracy than video tracker. (2) Voice Based method [3] in this method voice is use as input. Voice signal is converted into digital data by voice analysis. This type of system may degrade due to noise.Voices from the surrounding may affect the system performance. Accuracy of this system is very less due to background noise, variation in speaker, variation in speaking style and speed of speech etc.
Keywords— Eye Gaze, Gaze tracking 1.
INTRODUCTION
(3) Motion based method [4], In this method computer is operated by the movement of the organs such as head, foot etc. Physically handicapped person required to take effort for navigation.
The eye moment can be use as best input source for handicapped and disabled people. This paper focuses on using eyes as controller which gives command to any object. The object here chooses as a wheelchair and have possible interfaced with a video game, toy car, an entertainment system. The purpose of selecting wheel chair is that of persons who are paralyzed and therefore dependent on others for its daily activities due to loss of self-mobility. Due to Diseases or accidents peoples are lose their ability to move their voluntary muscles. Because voluntary muscle people cannot to move their body, paralysis may cause a person not move their loco motor organ such as arm, leg. Many for such disable peoples control their eye movement which can become controlling part of the wheelchair.
3.SYSTEM MODEL In this system person seated on the wheelchair to develop a wheelchair that will be controlled by the their eyes. Eye tracking module is used which consist of camera to capture eye ball image. A camera is fixed to capture the image. The camera is placed so as to capture the movement of one eye allowing clear vision to the other eye. Output image from camera is processed by the MATLAB software. Once the image has been processed it moves onto the controller. A functional block diagram of the design system is given in fig. 1. In this block diagram mounted camera that will track the user eyes. Camera will take an image of the eyes that image will be processed and finally move it into controller. Motor driver system which interface to the wheelchair. Motor driver control speed and direction to enable wheelchair to move forward, reverse, left or right.
2.LITERATURE SURVEY There are many input devices which are use to interacted with the automated devices such as joysticks, keyboards, mouse etc. But all these devices required hand movement. These input devices cannot be used by people suffering from physical disabilities. The existing devices and their disadvantages for handicap person are as categorized:
4. SYSTEM REQUIREMENT Hardware :
(1) Bio-potential based method-There are some special instruments which utilizes potential from user's body actions.Instrument such as Electrooculography (EOG),Electromyography(EMG)[1], and Electro
