Mercedes' Futuristic Headlights Shine Warning Symbols On the Road (gizmodo.com) 139

In its new high-end vehicles, Daimler says it will introduce programmable, "million-pixel" headlights that project warning symbols and driving tips on the road. "The technology, which Daimler calls Digital Light, was demoed as a concept ten years ago, but at the Geneva Motor Show it's finally being introduced as a feature that's 'expected' to be available on certain Mercedes-Maybach S-Class vehicles sometime this year," reports Gizmodo. From the report: Sitting alongside the vehicle's standard headlights are a pair of small monochrome projectors that each feature "a resolution of over one million pixels," Daimler claims, resulting in an "HD-quality" image being projected onto the road surface ahead of the vehicle. Using data from the car's onboard sensors, as well as traffic and obstacle data that GPS devices rely on, the headlights project symbols like a snowflake indicating slippery conditions ahead, a construction symbol reminding drivers to slow down for road workers, arrows for where to turn, and even simple white lines representing the size of your vehicle so you can immediately tell if you're able to squeeze into a narrow parking spot. The ability to selectively switch off pixels means the S-Class' headlights could help drivers avoid blinding oncoming vehicles or pedestrians, as onboard sensors detect faces and windshields and automatically dim the brightness in those areas.

    I find it so cumbesome to fish out my phone to read texts, especially at highway speeds. It would be great if this feature will project incoming text messages. Also can it stream Netflix. I have seen the road many times, and there is no plot interest in the road or scenery. Would be great to have something interesting to watch other the road when I am driving.

          Watch this get turned into political messages, bad bumper sticker clones, and worse: advertising.

          And for those that shine dick pics: make sure the finish of your car can be protected from deep key scratches. I sadly know a couple of people who wouldn't hesitate..... or cut you off with millimeters to spare.

      No, but it will probably display ads.
    • Some neat effects can be done projecting onto building and statue faces and then suddenly animating them. Imagine the possible panic attack road hazards one could get. Huge cracks opening in the earth with lava bubbling up. A large 16Tonne weight suddenly falling from the above. A wrecking ball swingin down the road towards your windshield. A motorcycle tumbling end over end tossed by the incredible hulk.

      Kind of took the thrill away...

      Hey, with this technology, you can project pictures of pedestrians who aren't there right in your oncoming path. If you are skillful enough to "hit" them . . . you will get points!

    However the car is broadcasting data to the public, that an individual may not want to share. Lets say it is linked to the GPS and shows where to turn, for the most part that will be great, because it is like an enhanced reality display, except for the fact everyone else knows where you are going.

    Or if you see the warning displayed and you failed to take the accurate action leaving to a traffic ticket, because you don't have the excuse you didn't know about the road condition.

        I was thinking more about stay straight for 30 miles. Then turn right you have reached your destination.

        Turn signals are to tell people what you are going to be doing with your car. Vs telling where you car wants to be. Also this could give confusing information if the car says turn right and you decide to ignore that particular GPS request so the onlookers don't know if you just didn't use your turn signal, or you are going straight.

        • Not putting on your turn signal tells people you are going straight. You still need to use and observe other people's turn signals. I doubt many other motorist or pedestrians would be at a good vantage point to read these projections anyway. First because they are on the ground in front of the vehicle and second because they will be projected for the driver's vantage point and will look distorted to others.
          • by dgatwood ( 11270 )

            This is why serious offensive drivers learn to turn their turn signals on randomly and then leave them on for extended periods of time without actually turning or changing lanes. Only by actively engaging in disinformation can you truly keep other drivers on their toes.

        I'd hack it to project messages into the rear-view mirror of the car in front of me. Things like, "There's no traffic, the speed limit is 55, you're going 30. Speed up."

      This privacy concern is becoming more and more irrelevant. Social media narcissists always seem to feel the need to tell the world what they're doing and where they're going every minute of the day. You could probably find out where the person is going by looking at their social media accounts. It's easy to find them online since the vanity license plate is their fucking Twitter handle.

      In the UK it is illegal to display unofficial road signs, including painting them on the road, even if they are "true". For example many people have tried putting up their own speed limit signs where roads pass through their village, and I have been told am not allowed to put up road works signs when I cut my hedge which is on a country road. These projected signs would seem to fall into the same category; at best they are a distraction to other motorists. What's wrong with a heads-up display, or have th

    Current regulations are in the shape of 'no more than 55W (assuming halogen and ignoring more efficient lighting options that would produce far more light at that power level), light bundled in shape X'.
    As a result, modern headlight systems are usually fine when viewed from straight ahead, but become uncomfortably bright when viewed from an angle (encountering such a vehicle on a curvy road, or cresting a hill). All too often I can't see shit because of that.

        I wouldn't mind some lumen limits. I've been blinded too many times myself.

        Brightness isn't the problem. It's vehicle height and headlight adjustment (as well as lazy people driving with their high beams on). Too many vehicles are being made stupidly high in the SUV craze but don't have their headlights adjusted downwards to prevent blinding drivers in normal sized cars. Manufacturers don't do this because it would make their vehicles unsafe to drive at night and lets face it, SUV drivers are terrible at the best of time.

        • by Rob Y. ( 110975 )

          Some of the bikes in the NYC Citibike system have something like this. They project a bright green picture of a bicycle onto the road in front of you. I assume this is so cars can see you coming - not for you to look at. But it's super bright and annoying as hell. Now, part of that might be because the projector is mounted on the handle bars, so the image moves around as you swivel the front wheel. But still, imagine a road full of cars projecting bright lights onto the street. Uggh.

      • You don't need to limit the lumens, you need to control the beam direction. If you've been blinded either someone has their high-beams in your face (already illegal in most of the world) or their lights aren't dipped enough (already illegal in most of the world) or their lights have been modified with an illegal beam pattern (err redundant, but already illegal in most of the world).

        • by Cederic ( 9623 )

          Or they just came over the brow of a hill, or over a humpback bridge, or they hit a pothole, or the road just isn't as flat as Holland.

          Yeah, can't imagine any scenarios in which a stupidly bright light would never shine in another driver's face.

          • Your issue is not the lumens. Any headlight that can suitably light the road will already blind the oncoming driver. This is precisely why variable dipped beams and projectors were invented in the first place.

        • Or I'm driving a compact and coming the other way is a lifted pickup or bigass SUV.
          • And if his beam his your eyes than his height is already illegally setup. A new law doesn't fix this.

      • by Anonymous Coward

        Colour temperature is important too. Why the super-high bluish-white temps? At night!? Yeah,because we can market it as "starlight"... whatever! Warmer colors (yellowish-white) would be better for both the driver and those who get blinded by that light.

    • by Anonymous Coward

      N. America could do with the same headlight lighting pattern as in Europe, where there's a sharp cut-off to prevent dazzling and an up sweep to light the edge of the road, which makes it easier to drive curves in the dark when there are oncoming vehicles. The downside is that N. American roads tend to have more overhead signs, which don't get lit up so well.

      Oh, and maybe a real driving test so people don't use their lights inappropriately, some real enforcement to discourage those who continue to do so, an

      • I'm in Europe - the sharp cutoff and upsweep are what's causing the problems.
        The upsweep illuminates the road and oncoming traffic when you're going through a righthand curve. A hill, bump or slight misalignment puts oncoming traffic within the cutoff.

    • US Headlight regs have always sucked. Back in the day, we'd toss the US DOT lights and insert E code lights. A 55/60 H4 plus a 100 watt H1 on a separate relay and switch took you from city to the ability to spot deer on farm roads. Today I am convinced the base lights on most normal cars are like the base stereo. It is designed to make up buy the upgrade. US headlight regs still suck but unless you get the HID option, you still aren't as good as the H4 setup I bolted on back in the 80's. My current ca

      This! My pet peeve is when the two vehicles are at different heights or angles. In the hilly Northeast, its a sort of roulette. The oncoming car's lights might be focused on an area that isn't an issue, or you might be able to count the veins inside your eyeball. Some times I think that the people who designed these damn highly focused headlamps never ventured out of Northwest Ohio, where the land is utterly flat.

      A different issue is the stupid blue lights. It has been known for a long time that visual a

    This is really bizarre. I'm not sure why projecting onto the road is better than using tried-and-true technology like HUD (Heads up Display). Surely it would be better to project warnings etc. via HUD vs. onto the road? I have a HUD in my BMW and it is one of those technologies that I found genuinely useful and non-obtrusive.

    For example, it shows turn by turn directions projected onto my windscreen, so I don't have to move my eyes or head. The location is just perfect and doesn't obstruct anything.

    Would be great if we could understand the rationale Daimler used to project vs. HUD. I'm sure there's a reason, I just can't figure out what it would be.

      Also, HUD is where it should be - within the car, no distraction to others around it.

      Imagine if everybody projected $WHATEVER onto the road... overlapping, rendering things unreadable anyway.

    • Would be great if we could understand the rationale Daimler used to project vs. HUD. I'm sure there's a reason, I just can't figure out what it would be.

      The HUD is one of the few few features in newer BMWs that I would like to have in my '11. I've driven loaners with it and found it useful (would be more useful with the tach, which they reserve for M models IIRC). And of course the HUD works fine in the rain, fog, and any ambient lighting condition. I'm not sure how well these projectors will work in the daytime on a snow covered road. Seems like a solution to a problem that is already better solved.

      • Would be cool if they could actively avoid illuminating snowflakes in a snowstorm so you could see.

    • I can: cost. a hud would require a much more expensive precision engineered windshield and windshields are commonly replaced. I have already heard problems with current forward-collision detection systems that point a camera out the front window. Buy a cheaper aftermarket replacement? Well its properties are different and the system goes nuts and doesn't work.

      Exactly what I was thinking. Headlights are expensive enough to replace already - plus, making them more complicated will almost certainly increase the frequency they need to be replaced.

      Not that Benz owners aren't already used to paying through the nose for simple car repairs...

  • for other drivers/pedestrians, but the info should use HUD. Doesn't Benz offer this as an option? I know GM, Lexus and Honda offer it. I imagine the patents GM filed when they first offered it have expired by now. Its been in their cars for 20 years or more. The current car I have offers nav directions on the HUD. Works great.

  • So far not useful. What would be useful is to have a lidar or radar system that can actually detect deep potholes and deer, paint it with a laser, and use the headlight projectors to indicate where it will be and where you should move the car, assuming the car is not smart enough to avoid them itself. Car mountable projectors actually could be powerful enough to fully illuminate a deer but what happens in fog? The headlights could at least alert you to something the car can detect while keeping your eyes at
