Abstract:Driver fatigue is one of the major causes of accidents in the world. Detecting the drowsiness of the driver is one of the surest ways of measuring driver fatigue. In this report, we discuss a method for detecting drivers’ drowsiness using Haar Classifier[I] and Template Matching Algorithm. The system then subsequently alerts the driver in order to prevent accidents. It works by monitoring the eyes of the driver and sounding an alarm when he/she is drowsy with the help of a camera that points directly towards the driver’s face and capture the video. Once the video is captured, monitoring of the face region and eyes is done in order to detect fatigue. The system monitors eyes and determines whether the eyes are in an open position or closed state. In such a case when drowsiness is detected, a warning signal is issued to alert the driver. If the driver’s eyes are closed cumulatively more than a standard value, the system draws the conclusion that the driver is falling asleep, and then it will activate an alarm sound to alert the driver. Yawn component is detected using Template Matching Algorithm to detect whether the driver is yawning or not and …show more content…
subsequently the driver is alerted with an alarm. Keywords: Haar Classifier, Template Matching, OpenCV, Drowsiness. 1. INTRODUCTION The issue of distracted driving has become common especially in a society that is more susceptible to multitasking while driving.
This issue has increased the urgency for driver inattentiveness and drowsiness detection system technology, to compensate for driver error. The system which is developed will run in a simulated environment with a subject (driver) sitting in front of the camera which is integrated with the software. This system will present a non-intrusive approach for drowsiness detection based on computer vision. A camera is placed in front of the driver in order to detect his face and obtain drowsiness clues form their eye closure and yawning component. If the system detects that the eyes are closed for a certain no. of frames then it will buzz an alert alarm indicating the driver to be
alert. 2. LITERATURE REVIEW Need for the system Industrialized countries, drowsiness has been estimated to be involved in 20% to 23% of all crashes. Increase in such fatal crashes has urged many automobile companies now-a-days to build their own software that will detect whether a driver is feeling sleepy and fatigue well in advance. We have thus build a system that will detect when drivers are becoming drowsy and promise to be a valuable aid in preventing accidents. The system uses a small monochrome camera that points directly towards the driver’s face and monitors the driver’s eyes & mouth in order to detect fatigue. This report describes how to find the eyes, and also how to determine if the eyes are open or closed and the mouth structure to conclude whether the driver is yawning or not. The system deals with using information obtained using Haar-based classifier to find the edges of the face, which narrows the area of where the eyes may exist. Once the face area is found, the eyes are found by looking in the area of the cropped face to determine whether the eyes are open or closed. If the eyes are found closed for specific no. of frames (for instance 8), the system draws the conclusion that the driver is falling asleep. The system keeps track of the mouth for detecting yawn using Template matching Algorithm which detects the yawning component by matching the templates already stored in the system. A combination of both algorithms helps to achieve good results.
Most of the Aviation accidents have been greatly attributed to “Pilot Fatigue” (Mohler, 1998). This is because a pilot’s input into the aircraft is majorly dependent on his consciousness on the job, therefore incase he or she may be fatigued then this provides room for error in his inputs (Smith, 2008). Even though the technological advancements in avionics the flight systems of the current aircrafts have preventive mechanisms put in place that makes sure that the pilots are always alert, without sleep and freshened, small effects of fatigue can greatly jeopardize flight safety (Mohler, 1998). This is so because the duties performed by the pilot in the cockpit require a lot of vigilance, care as well as both mental and physical well being and alertness. Having considered this it is very hard to eliminate the cockpit noise, aircraft vibration, the long flights; little sleep as well as irregular work schedules which are the major contributors to pilot fatigue and which can have great influence on his or her performance. This paper dissects the major factors that cause pilot fatigue; the impact of pilot fatigue as well as the damages associated with the same and concludes with ways of managing the same.

Distracted driving something that is known too well, and can been seen on a day to day basis on the road. But what is the underlining cause, and biggest reason for the negative impact of distracted driving. The conversation addresses the issue of DD (distracted driving), convey that adults and teens need to educate themselves about distracted driving. To inform adults and teens, 3 main points will be addressed in this paper, what is counts as distracted driving, what is the culture of entitlement, and lastly address some data.
Drivers do not fall asleep without warning. If a driver consciously decides to drive without the ability to remain alert they are putting themselves and others at risk in the same way that those who text and drive or drink and drive do, with the consequences just as devastating. Therefore, it should be treated the same by
Alarms sound around-the-clock in acute care settings, subjecting staff to a constant barrage of noises in the workplace. Alarms were designed to alert providers of abnormal values; unfortunately, because of the high sensitivity of these devices, there is very low specificity. Low specificity coupled with the human factor compromises patient safety. When alarms are missed or when there is a delay in response, alarm fatigue is often to blame. This paper summarizes the factors contributing to alarm fatigue, the consequences of alarm fatigue, and the evidence-based interventions used to address alarm fatigue that were found within the literature. The paper closes with the application of the Quantum Leadership theory to the implementation process for one of the recommended evidence-based interventions found within the research.
Driving distorted is very dangerous. I will tell you straightforward I catch myself texting and answering phone class while driving often. Because driving distorted is such a problem, writing this paper will
Although the radio systems in our cars and trucks are a great source to keep us entertained during our trips, they can be a huge safety hazard to not only ourselves, but also to other drivers sharing the road with us. When a driver takes his or her eyes off of the road to change the channel on their radio or to turn the volume dial up or down, they can veer into oncoming traffic or strike a pedestrian. Distracted driving is ...
Yes i am against distracted driving. There has been so many accidents, most of them have to do with texting and driving, and as there are also people that think it is not wrong and through there mind it doesn't cross that they could end their life, or someone else's life. Can People Understand The Importance Of Distracted Driving?
Truck driving is a difficult job which requires great responsibility of transferring the goods from one place to other far place with proper safety. Genuine CDL training is required by every aspiring truck driver to attain essential skills as a professional driver. These training programs are meant not only help the students learn about the possible ways to handle and manage their trucks in most adverse traffic and weather conditions, but also, this training helps them to learn how to prevent any major loss of the goods during the transference.
Most people can recollect their initial experience behind the wheel of a car. Their palms are sweaty and they might feel butterflies in their stomach as they are nervous for the exciting task ahead. Indeed, driving a car for the first time can be an extremely exhilarating and daunting job for most people, and the fundamental goal on their mind is to arrive at their destination in the safest manner possible. After several commutes, however, a driver begins to feel more comfortable. Consequently, I believe ease and relaxation are the roots of the issue when addressing distracted driving. A person loses focus after garnering a substantial amount of experience behind the wheel, leading to many negligent acts of which all drivers are guilty.
Have you ever been driving on the road and felt the urge to want to pull over because you were too tired to continue driving? Most of the times this happens because the person is maybe lacking the appropriate amount of sleep needed. Many motorists think they know how to counter fatigue: turn up the radio, roll down the window, and talk on the phone. But most of times these remedies aren’t enough to keep the driver alert enough to drive. The most suitable thing to do is to take a quick fifteen to twenty minute nap or drink some coffee to help enhance driving awareness.
One of the worst feelings is when you are making a long drive in a car and realize you don’t remember the last half hour or longer. Sometimes people say they were on autopilot but most likely, they are suffering from some form of fatigue. According to Webster’s dictionary fatigue is the state of being very tired or extreme weariness. (Webster’s 2015) This can be very dangerous while driving a car, and even more dangerous while flying an airplane.
This illumination appears as a glint on the cornea of the eye and is called as corneal reflection. This glint is used as the reference point for most of the existing work for gaze estimation. Whenever the head moves the glint will clearly change location, but when changing gaze direction occur it is less obvious that the glint shifts position. Merchant et al. in 1974 introduced the beginning work employing a single camera, a collection of mirrors and a single illumination source to produce the desired result [6)]. Yasuk Sugano et al. proposed a gaze tracking system which in coperate a single camera mounted on the monitor. The head pose of a person is estimated in this system by using a 3D rigid facial mesh [7]Ohno et al proposed a single camera system with a single glint [8]. Matsumoto et al. developed a system which computes the 3D head pose and estimate the 3D position of the eyeball using a single stereo system [9]. Wangand Sung also proposed similar approach[10]. Paul Smith et al. proposed a system with a single camera for monitoring head/eye motion for driver alertness [11] Chi Jian-nan et al developed a system consisting of active infrared source and a camera used for pupil tracking based on particle filtering . [12]. Laura Sesma et al. introduced a gaze tracking system based on a web cam and without using infrared light is a goal to widen the applications of eye tracking
... been research how drunk drivers are the same as people using cellphones. According to Strayer (2006), drivers who were conversing with cellphones, their braking reactions were delay and were involved in car accidents. However, drivers who were under the influence were more likely to drive aggressive and brake very close to the driver ahead of them. Drunk drivers driving performance decrease as well as a driver with a cellphone because their minds are off and are not focus around the road. However, there was a difference on the distance between the drunk driver and cellphone drivers. Drivers who use cellphone had longer distance between them and the car ahead of them. This shows how their mind is going slow and cannot multitask as much. Drivers can only multitask by doing two things at once, instead of doing everything at once.
There are two main parts must be considered, when study gaze behavior in any field, which are eye tracker device, and algorithms, in addition to this a functional task according to specific field must determine by experts to give indication about something related to aim of study.
