-Eyeball tracking is the only method in human behaviour research rendering it possible to objectively measure and quantify eye movements in real time.

-Here there are two sensors placed at both the ends of the eyeball sensor glass in order to sense the direction of the eyeball movement. 

-The sensor was attached to the implanted holder and positioned in front of the eye.

-During eye blink detection, IR transmitter rays transmit and observe when the eyelids are opened when eyelids are closed a reflected IR ray induces to the receiver from that we will get a digital output.

-Focus of technology

-System Capabilities

-Power supply voltage: 3.3V-5V

-Eyeball sensor glass drilled at both the ends for two sensors.

-No additional power supply 

-Operating current: 100mA

-Connect 5V power supply is given to the sensor.

-Connect Ground pin

-Wear the eye ball sensor glass on the face at a particular distance.

-LED blinks for each movement of eyeball; doesn’t blink when eyeball is static and straight.

-The output pin gives the digital output.
