Regarding traffic accidents in Japan,there are many rear-end collisions.
Most causes of rear-end collisions are by operators who are not concentrating.
Operating a car without concentrating is very dangerous.
Why do people not concentrate during operation why?
Driver's fatigue is related to it.
If a driver is in the state of fatigue,the body functions will fail.
Reaction velocity, circumstantial judgment, and the degree of arousal mainly fail.
If operating a car, it may become fatal.
Therefore, we have to prevent operation fatigue.
What should we do?
A driver needs to take a break first.
And researchers are developing a system which can detect fatigue.
Therefore, we are studying it now.
In the future, we will develop the system which warns of fatigue
