ABSTRACT
Eye motion interface computing is alternate to mouse. this device is design to communicate with computer with out any mouse device by only sensing with only eye ball’s movement we can operate computer and communicate with the computer.
In this device the IR(infra red) devices are used to detect eye ball motion according to the eye ball motion we IR will recognize the motion of the eye ball the IR and High pixel cam is attach to the top of the monitor to recognize the motion of eye ball. If left eye is closed in front of camera and IR it works like left click and simultaneously right eye works like right click of mouse. This device is used to connect with computers with out external device like mouse. Remaining concepts are explained in introduction.
INTRODUCTION
Eye motion interface computing device is used to interact with the computer and perform actionable events on the computers like mouse works to the normal computers.
With out using any external device or forcable device like mouse or joystick we can perform operation of computer with movement of eye. In this device so many thing have been used like IR device and high lens camera are used to capture the motion of the eye ball. If the eye movement is done then the pointer of computer arrow symbol will be moved on the computer screen as per movement of eye ball. If left eye is closed in front of camera and IR it works like left click and simultaneously right eye works like right click of mouse. This device is used to connect with computers with out external device like mouse.
The software programming is done to capture the camera signal and IR signal to capture motion of eye and cursor on computer screen will be moved as per instruction as IR signal according to obstructing of IR radiation to eye if eye is moved the cursor will be moved and if left eye is closed the left click operation will be performed as per computers left click and simultaneously right movements work like right click of mouse.
ARCHITECTURE
This device is created for operating computer by using eye motion .this device is used as sensor of the computer which captures the motion of the eye of human being. The infra red emitter pairs and high lens camera are positioned on the top of the monitor of the computer. This system detects eye motion by monitoring light fluesuations from infrared light. An infrared LED illuminates the eye and a phototransistor which detects the motion. Which senses the reflected light coming from the eye?
The infrared transmitter works on depending angle and movement of the eye of human being. The signal coming from the eyes is captured in the camera and there is one circuit which is a PIC micro controller, which searches for position of fixation. During fixation, the PIC uses infra red transmitter and camera placed on the top of the monitor. The environment is established by writing the visual basic program to sense the motion of eye. there is also PCB board .these devices gather the information stored on the circuit as well as interchange these information using USB port to establish connection with computers and do operation of the computers.
CONCLUSION
This device as good future in the IT market for security purpose it works like passwords checking machine with retina capturing as well as checking the password of people at bank a secure places.
It works like an interface like a mouse to the computer.
