Teenager rids cars of blind spots using a webcam and projector

  • As every cyclist knows, the blind spots caused by a car's roof pillars can be extremely dangerous. Although companies are working on various high-tech solutions for this problem, a 14-year-old from Pennsylvania has taken a more low-tech approach to create an ingenious fix for the issue.

    NOT NEW! Company's already developing this in Europe.

    This girl should return the $25,000 prize, because she doesn't even know where the blind spot is.

    The blind spot is on the left side one car length back. It's called the blind spot, because it is not covered by the left rear view mirror. The B-pillar (only about two inches wide) has nothing to do with blind spot.

    The A-pillars (sides of windshield) are NOT the "blind spot". If any part of the car causes blind spot, it would be the left B-pillar between front and rear doors, but that pillar is about two inches wide, so it cannot cause a blind spot.. In fact, the blind spot can be simply eliminated by adding a second mirror to the left side.

    Hmm... Before this is in production, maybe I could build this kind of system on my own to my car :)

    Omg, this is genius! A few years ago this would have save me from a "near-the-accident" situation. I hope this goes to every car! :)

    A cheap screen would be simpler to implement. Great idea though. This could be done in the rear pillars also.

    less concerned with this blind spot, and more concerned with the rear blind spot.. but nice idea and ingenuity

    • Lance Baker

      We do not need multiple blind spots. The blind spot is on the left side one car length back. It's called the blind spot, because it is not covered by the left rear view mirror.

    Makes me think... And what was I doing when I was 14.... Not coming up with AWESOME ideas and winning big prizes. Lol.

    Great to see teenagers handling things like this! The new generation can stand on the shoulders of those who came before to do some really cool things.

    It would be much better applied to the rear pillars, which can be gigantic in most crossovers. Plus, the rear pillars are mostly vertical so the projection can be fine tuned to avoid external glare.

    I actually thought if the pillar doing this year's ago.
    Never thought any one would make it a reality.
    Thanks and congratulations for call of tour hard work and problem solving😊🙏👍

    An OLED with eye tracking is the way to go. A rigid camera is gonna create more issues because of parallax

    Tesla does it better than all others so far. Which automaker can catch up?

    Augmented reality could also do this, but the fact that it is this simple to do with just a basic projector and a web cam shows how disconnected from new ideas car manufacturers are.

    While it is a pretty cool design and idea, I would not consider that strip of the car a blind spot. Never had a problem with that small section of car blocking my ability to see a car. I think everybody considers the blind spots the side of the car where the side and rearview mirror does not show a car.

      It just makes life easier since it's less of a thing that your brain has to imagine full & only needs to pay attention too. You don't really need a reverse camera, signal lights, a/c, windscreen, roof, etc but it makes life easier for everyone!

    BAD REPORTING.
    I already explained this on the Gizmodo post, but I'll put it out again because these things have to stop.

    Nothing against the girl that came up with this system, it is great that teens like her are trying to tackle everyday problems like these with a investigative scientific mind. But it is also important for fair judges and tech publications to put these things to scrutiny before reporting about it mindlessly. This should not hold even for people with some experience with cameras, let alone for an entire scientific body and journalistic scrutiny. Pay attention on what you are reporting instead of following the hype.

    The problem here is about parallax and stereoscopic vision of the driver.
    This system, which has been proposed for years from motor companies and other scientists does not work because it's not taking the driver's perspective in mind. It's taking a camera's perspective in mind.

    It works on camera and on paper because it's taking a fixed camera point of view to demonstrate the idea.
    It's fairly simple to align a projected image to the windshield pillar in order for that to match what is going on outside, but this does not work for a driver that has a pair of eyes and is constantly moving around.

    In fact, it's actually a dangerous idea because due to parallax shift, the projected image becomes misaligned, and it might actually conceal what is actually out there adding another layer of confusion for the driver.

    If you wanna understand this for yourself and my explanation wasn't enough, just experiment a bit to see for yourself. Get a piece of paper, hold it in front of your eyes simulating the windshield pillar, try drawing what is a meter behind it or something. After doing that, try aligning the image. You'll see how hard it is. Even small shifts on your head position will throw the whole thing off.
    Now, you pick that and imagine it as something applied for all sorts of windshield pillar designs, heights, widths and whatnot, and then imagine all sorts of drivers from tall to short, moving their heads all over the place, and then you understand why the idea is impractical.
    The only way to have something like that work a little better, but not perfectly, is by having a eye tracking device that will adjust the projected image in real time all the time so that it aligns perfectly and reliable - which is extremely hard to do.

    So there you go. Again, no problems with the prize winner. On paper, it's an interesting idea that is trying to think critically about an everyday problem. But it's really bad when it's replicated like this without any criticism. People don't learn anything with stuff like that.

      Your technical explanation is sound but the report was just on how a simple idea was used by this girl to make a solution. As it stands, though it's not the best & most practical solution out there, least she came up with an idea that could be improved upon!
      Your brain is not a fixed object. For example, there are still people who can't / prefer not to use reverse cameras but it has also saved countless people & stopped accidents from happening since it gives more information for you to process than just using the rear view & side mirrors.
      No technology is perfect but least someone has to start somewhere & this 14 year old girl made that good start! Now it's up to the rest of the world to improve upon it & do it better.
      Hey even the original RU-clip sucked but now has so many things including a place to voice out your words and like / dislike em and serves as a platform to let so many share so many things! 😅

    Need an oled screen and eye tracking.
    Wait, does it already use eye tracking?

    • Alex Myladoor

      No as in... ( Lol) I doubt it has eye tracking. Yes it definately needs one😂

    I could see putting an OLED screen on the pillar as a more practical solution.

      For school project pico projector just to show idea is better option than custom cut oled screen.

      But for mass production oled option is avalible camera screen and processor can be put in car pillar as one unit

      It costs much more, and you have to build it onto the car, and it can damage easily.

      The A-pillars (each side of windshield) are NOT blind spots. The blind spot is on the left side one car length back. It's called the blind spot, because it is not covered by the left rear view mirror.

    Volvo did this over a decade ago of course it didn't go to production, but their idea was using screens in the pillars back then those were LCDs, now we have OLED flexible screens just fill the surroundings of the car with cams and can even have a free view to the sky without the wind.
