Students made driver anti-drowsy system
This system is installed opposite the driver. When the driver detects signs of sleepiness, the system will issue a sound alert to wake up.

The above feature is the effect of the warning system of driver drowsy cars created by two students in Thua Thien Hue. They are Han Tho Nhat Phu and Hoang Quoc Huy (An Luong Dong High School, Phu Loc District) with the guidance of teacher Dao Van Phung.

According to Phu, the phenomenon of drowsiness in traffic of long-distance drivers is quite common. This is really dangerous for the driver himself and the others.

The system is installed opposite to the driver. Light in the car should be moderate and do not shine directly into the camera affecting the ability to recognize the system. The programmed algorithms are responsible for detecting the driver's eye blinking state in real time.

Next, the camera scans and calculates the distance between the eyelids. If the eye closes below the specified level for a period of 1 - 3 seconds, a warning will be issued.

Phu shared: “The system can send messages to the driver and the owner of the management company (for taxis and buses) to take measures to alert, remedy and manage the driver's driving time. The system is programmed on a miniature CPU with camera and speaker connectors so it can be easily adjusted according to user needs.”

The system is a mobile product that can be moved and installed in any convenient position with high accuracy and quick warning. In addition, the installation, warranty, maintenance is quick, easy to upgrade, convenient and cost-effective. This system works well in low light conditions.

Through empirical testing at a distance of 40cm from the eye and 100cm, obtained an accurate result of 88%.
