What is the use of eye blink sensor?

This eye blink sensor senses the eye blink using infrared. The variation across the eye will vary as per eye blink. If the eye is closed, the output is high otherwise the output is low.

How does eye blink sensor works?

The project involves preventing accidents due to drowsiness in vehicles by using eye blink sensor. The IR transmitter transmits infrared rays into the eyes. The ray reflected from the eye is picked up by the receiver which is in a straight line to the transmitter.

What is eye blink detection?

Passive eye-blink detection methods do not use additional light sources. The blinks are detected from the sequence of images within the visible spectrum at natural illumination conditions. Most eye-blink detection techniques are in fact methods detecting eye regions in images.

What is the reason for eyes blinking?

Blinking lubricates and cleans your eyes by spreading your tears over its outer surface. It also protects your eye by closing it to keep out dust, other irritants, very bright light, and foreign objects. Babies and children only blink about two times per minute.

Can IR sensor detect eye blink?

This mechanism helps in detecting the eye blinking system. In eye blinking detector circuit, IR LED emits the light which is reflected by the eyeball surface, falls on the IR photodiode, and changes the output voltage.

Why do my eyes blink by itself?

Blinking more frequently can be annoying, but it’s rarely a sign of a serious issue. Some possible causes of more frequent blinking include: eye irritation, due to irritants in the air, dry eyes, a scratch on your cornea, inflammation of your eyelid or iris, having something in your eye, or other reasons.

How is blink rate calculated?

The blink duration is measured in seconds and corresponds to time difference between the start and end points of a blink. The interblink interval, also measured in seconds, corresponds to the time difference between the end point of a blink and the start point of the following blink.
