How to prevent the car from the driver's sleep?

Sleeping is one of the main causes of traffic problems, as many studies have indicated that 20 to 50% of road accidents related to driver fatigue, and lack of concentration during driving.

So car companies have developed systems to detect the driver's drowsiness, monitors performance, and provide alerts or stimulus when it appears on the driver's fatigue, or even urging him to stop to take a rest. They techniques can generally be divided into three main categories.

Follow-up vital signs

The initial technique is based on monitoring the status of the driver depending on the signals vital, such as brain activity, muscle, heart and blood vessels, but the problem in this purification they require the installation of a standard medical tools on the body of the driver, a Omrkd cause him Alazaaaj.lkn is expected that this technique is commercially viable, if it is to find a way through which is detected on the driver without the use of any tools prove on his body.

Follow-up driver behavior

The second technique is based on the idea of ​​working on the driver's control, which includes the steering wheel, and vehicle speed, maneuvering and other signals recorded angle behavior, and the advantage of this technique is that there should be meaningful, easy to obtain. This system is used commercially in cars Daimler Chrysler, Volkswagen, Ford, on the other hand, these systems are subject to several limitations, such as type of car, and the experience of the driver, and the characteristics of engineering, and road condition, which requires a great deal of time to analyze user behavior, and therefore the system does not work if The driver pig for a few seconds, in a very straight street, for example.

Visual Analysis

The third technique is based on the visual analysis of the driver, using image processing techniques, where computer vision be monitoring the driver without the bother him, through some of the installed cameras in front of the driver, and algorithms for analysis, which picks up the ongoing him pictures, looking for sleep signs reflected on the driver's face and his eyes, and which, if any, the system works on the driver's warning to regain his focus.
