3.  It is the equivalent of the conventional computer mouse, but it is entirely controlled by eyes.  This is boon for the disable people who are not able to use physical mouse properly. Introduction

4. Block Diagram

5. A sensor is a device that receives a signal or stimulus and response with an electrical signal Sensors

6.  It measures infrared (IR) light radiating from object.  Infrared waves typically have wavelengths between 0.75 and 1000µm. IR Sensor IR light from LED IR light reflected off object IR LED IR receiver

7.  A gyroscope (from Greek guros, "circle" and skopeo,"to look") is a device for measuring or maintaining orientation, based on the principles of angular momentum.  Sense angular velocity.  Angular velocity is the change in rotational angle per unit of time. Gyroscope

8.  Arduino is a micro controller board using on the ATmega8.  Open source electronics prototyping platform.  Easy to use hardware and software.  Atmega8L has 28 pins.14 digital I/O pins(6 PWM output).6 analog I/O pins.  Clock Speed 16 MHz.  Flash Memory 32KB,SRAM 2KB,&EEPROM 1KB. Arduino

9.  Easier computer control.  Help disabled & handicapped people to use computer.  Helpful in commercial interactive games and advertisements. Advantages

10.  Improper usage may lead to eye problems.  Calibrating the equipment takes time.  The eye as a computer input device, difficult to control eye position consciously and precisely at all times. Limitations

11.  It is very helpful device which can replace a normal mouse device.  It is very simple and multipurpose and helpful in virtual or interactive computer gaming and advertisement.  A gift for physically challenged people. Conclusion
