No it won't do that directly. Even if it is longer then a blink. And the reason for that is false positives. It is _very_ hard to see the difference between a person looking down and when the person is closing the eye.

The system usally have an EXTENDED_EYE_CLOSURE signal that is triggered after a certain time (together with a quality value of this signal). So not directly, but yes, close too.

But it is still tricky. What happens if you start blinking and then the camera get covered. Should it warn? It can not always warn if it loses tracking.

How should it warn? Disturbing the driver can actually cause accidents.
