Digital Dashboard Device Detects Driver Drowsiness

Pickens writes "Science Daily Headlines reports that researchers at the Fraunhofer Institute for Digital Media Technology have developed a self-contained, dashboard-mounted assistant system that tracks a driver's eye movements and issues a warning before the driver has an opportunity to nod off to sleep. 'What we have developed is a small modular system with its own hardware and programs on board, so that the line of vision is computed directly within the camera itself,' says Professor Husar. 'Since the Eyetracker is fitted with at least two cameras that record images stereoscopically — meaning in three dimensions — the system can easily identify the spatial position of the pupil and the line of vision.' The cameras, which can be installed in any model of car, evaluate up to 200 images per second to identify the line of vision. If the camera modules detect that the eye is closed for longer than a user-defined interval, it sounds an alarm. The Eyetracker also has applications in computer games where players could look around themselves without requiring a joystick to change their viewing direction, and in marketing and advertising, where researchers could determine which parts of a poster or advertising spot receive longer attention from their viewers."

      And I wonder what if the system detects it correctly, issues an alarm, but the driver doesn't wake up with the alarm? Maybe the environment is already noisy (for sound alarms), has lots of lights (light alarms) or the car is shaking a lot (vibration alarms). Or maybe the person is so tired that the alarm doesn't work at all.

      I think someone should just not drive when tired. If a person is aware that may fall into sleep at any moment, then maybe it's just stupid to drive anything.

      I imagine the opposite, where the alarm sounds off and the driver goes and takes a rest rather than continuing driving. Or in a scenario with passengers, one of the passengers say 'Hey you're falling asleep let me drive/take a rest.' It'd be harder for the driver to say 'I'm fine to drive' when there's an alarm like this going off ever few minutes.

      I really don't think that people are so stupid that they will think that they are not tired because a car alarm hasn't gone off. Do you also think that people won't use brakes because they can stop by driving into a wall and have the airbags protect them?

      If the car starts beeping to wake you up then you have long gone past the time that you should have stopped for a rest. While you might not actually close your eyes, extreme tiredness slows the reflexes to the same level as driving while intoxicated.

      The problem here is that tiredness is something that a) creeps up on you, and b) impairs your ability to make judgements, including "am I too tired to drive?".
      I doubt there's anyone here who's been driving for a while who hasn't ended up driving at least once when they've become very tired, and it's taken a shock to make them realise how tired they actually were.

      For the learning-impaired moderators:

      ABS isn't just for snow and ice. ABS will stop you faster slamming on the brakes on a dry surface than trying to keep from skidding without it; if the tires are skidding, they have almost zero traction, as was demonstrated in a driving course in the USAF. ABS will stop a car faster than the same car without it in any conditions. The added benefit is you can still steer with the brakes slammed on.

      Anybody stupid enough to not wear their seat belts because the car has air bags isn't going to wear their seat belt anyway.

      Not looking at the speedo is safer than looking at it -- you have to take your eyes off the road for a second to see the speedometer. Plus, your gas mileage is much better using your cruise than driving without.

      This is wrong. What ABS does is allow you to control the direction of your car when your tires would otherwise lose traction. In fact, the stopping distance with ABS is actually longer than without.

      No, do some research. If your brakes are locked up all your "braking" is the friction between tire and road. When the wheels are turning the brakes change kenetik energy to heat. This was proven decades ago, it's elemental physics.

      For the test, they equip cars with a device with a gun that shoots chalk when the passenger presses a button, when the brakes are applied, and when the car is stopped. It's a VERY effective demonstration of reaction distance and stopping distance -- I've participated in this. I agree it's counterintuitive, but much in physics is.

      Being able to steer while the pedal is mashed is an added advantage.

    Drivers will oppose it. That's the main problem.

    Drivers usually know when they're tired, but they tend to drive anyway. They don't need some electronics to tell them this.

    They drive because they're impatient and not driving would be an inconvenience to them. It's not so much they don't care that they'll be involved in an accident, it's just that they don't think it'll happen to them.

  13. Head movement by Laser+Dan · · Score: 3, Interesting

    I wonder how well it copes with head movement.

    TFA shows very zoomed in images of eyes and two large cameras, but they say the system is "half the size of a matchbox". If each camera plus processor is really so small, that's a pretty good system. And they say it can do it at 200 FPS? Thats a lot of image processing.

    I suspect they locate the eyes in a low resolution image first then just process the eye regions at 200 Hz, keeping them centred to account for head movement. Otherwise it would be impossible in the matchbox size with current DSPs.
    Anyone have more details?

    It sounds an alarm when your eyes are closed for more than a blink. I'd welcome this, as any sane person should.

    There are several problems here.

    The first problem is that tired people are not necessarily closing their eyes. What happens is that they drift away in their thoughts and lose concentration; they keep looking but stop seeing. A camera like that can't help here. An EEG helmet might be more effective but totally impractical.

    The second problem is that in southern states (CA to FL) you must use dark sunglasses from 6am to 8pm during summer (and a bit less during winter) simply because there is too much of sunlight here. How is the camera going to see through the dark lenses of those glasses, and reject reflections at the same time? And at night, with glasses or without, it's too dark for the camera to see the driver's eyes anyway.
