14-Year-Old Inventor Solves Blind Spots (gizmodo.com) 125

Alaina Gassler, a 14-year-old inventor from West Grove, Pennsylvania, came up with a clever way to eliminate the blind spot created by the thick pillars on the side of a car's windshield. All it requires is some relatively inexpensive and readily available tech available at an electronics store. Gizmodo reports: Her solution involves installing an outward-facing webcam on the outside of a vehicle's windshield pillar, and then projecting a live feed from that camera onto the inside of that pillar. Custom 3D-printed parts allowed her to perfectly align the projected image so that it seamlessly blends with what a driver sees through the passenger window and the windshield, essentially making the pillar invisible.

Gassler's invention isn't quite ready to be installed in vehicles across the country just yet, but the technologies already exist that would allow it to be implemented in cars without serving as a distraction to the driver. Short-throw projectors could be installed at the base of the passenger side windshield pillar to create the image without having to worry about the passenger blocking the beam. And many cars have already replaced side mirrors with cameras, or include nearly invisible cameras in the rear for safely backing up, so adding one more on the side of the pillar would presumably be trivial.
Gassler won the top prize for her invention at this year's Society for Science and the Public's Broadcom MASTERS (Math, Applied Science, Technology, and Engineering for Rising Stars) science and engineering competition.

      It'd take about 30 seconds to come up with something much lower cost [slashdot.org] than multiple active video systems which would work better than this idea.

        Such a lens would also project sunlight into your car in odd ways that might well blind you unexpectedly. I suppose that could be mitigated with photochromic pigment in the lens, but then it's not going to work well when it's sunny.

    Unfortunately, it doesn't take into account that it only works from that exact eye point. Move your head a bit and it stops working as it should.

    Still, better than the current solution of jerking your head back and forth to see what's behind the pillar.

    • That's not where the blind spot is. How is this a good idea?

      • When you're rounding a blind corner, it cuts several degrees out of your field of view (on both sides of the car; driver's side gets more view blocked, but more easily overcome with head movement), at a time when it would be beneficial to have visibility there.
    • Frankly, I like the pillars to be somewhat large, as they provide additional sun blocking (and for really no other reason). Now, I can see how someone with a stiff neck (or otherwise reduced mobility) might benefit greatly from this, as the POV issues would be less relevant.

    As other people have noted, this prototype will only work if the driver keeps their eyes in one place - this problem is easily solved with a 3D printer just as was done with the blind spot elimination.

    Regardless, Ms. Gassler showed great ingenuity and a willingness to experiment to put this concept forwards.

    Great job!

    • When all these smartphone addicts grow up and learn to drive, they won't know you can move your head to see around the pillar so it's not really a problem that needs addressing. 3D is an old persons reality.
    • As other people have noted, this prototype will only work if the driver keeps their eyes in one place

      Yep, true for the prototype, but for a revised version, it's entirely feasible to have a couple of cameras (or the sensors they use for face unlock) to monitor the driver's face, calculate where the eyes are in 3d space, and adjust the projection accordingly.

    • Her next invention will be a head vice

      A head vice is needed to create the problem in the fist place, you are supposed to learn to move your head side to side to see behind the A-pillar.

      That's a little different because it uses OLED screens and, based on the diagram, apparently shoots lasers into the drivers eyes or something. Well, I guess it is supposed to illustrate that it triangulates the driver's head position so that the image seems to be from their point-of-view.

    The most important blind spot is the one behind you that your mirrors can't see, not the one caused by the pillar.
    • This is true, but in my opinion, it's a step in the right direction (360 degree unimpeded visibility). Given its location, it could perhaps be dual-purposed to display images from the more substantial rear-side blind spots.

      Completely agree. The Volvos that I've rented the last few years have included blind spot indicator lamps [volvocars.com], which seemed like decent enough solution.

      For the forward-facing pillars, I'm curious how it might work to instead make the windshield glas near the pillars slightly refractive, to allow angling in light from the area that the pillars cover.

    Well, like others have said, this idea is not new. But the bigger problem is that the forward wind-shield pillar blind-spot is NOT a problematic blind-spot because you have direct line of sight while looking forward (just move your head). This is a solution in search of a problem. If you are able to move your head and see in front and behind a blind spot, it is not a critical safety issue. Poor driving skills should not be compensated for when the solution simply requires an attentive driver. This just leads to more bad drivers on the road who can't take control of the vehicle if the technology fails.

    Secondly, physics demands that the image you see must match the parallax for the individual driver or the image will become jarring similar to the reaction people have with VR. The image does not make sense to the brain and causes confusion and inaction and will create more accidents.

    Lastly, as science and your driving manual will tell you, the true blind spot is behind the car caused by the intersection of the fields of view from the side mirrors and the rearview mirror. There is part of the complete field of view that is obscured when using these mirrors because the mirros do not fully overlap. Note, this blindspot is created by the rear pillers. This then is a critical safety issue. However, all is not lost. You can actually turn your head and look backwards when changing lanes in order to see if a car is in your blindspot. Because many people are bad drivers and DON'T do this, is why so many cars now have warnings in the mirrors to tell you there is a vehicle in your blindspot. We are already catering to the inept. And now we are trying to solve a problem solved by a lower complexity solution with a higher complexity solution with no proven value and many obvious MEDICAL and NEUROLOGICAL issues resulting in new safety issues. Solving the wrong problem doesn't make you smart. It means you didn't research the problem.

    One final parting thought: When dealing with light, invisibility or relaying light, high tech is not always the answer. Unfortunately, when you have a hammer, everything is a nail. The right answer in this situation is transparent aluminum or the equivalent. (Thank you Star Trek, the Voyage Home, and Scotty).

    • This just leads to more bad drivers on the road who can't take control of the vehicle if the technology fails.

      ..and consider the different kinds of failures that can happen. It wouldnt be so bad if the only failure mode was a black screen, but we all know that wont be the only failure mode. What happens when the cpu/gpu driving it locks up? Now instead of a blind spot, you have an "unblind spot" that is lying to you.

      "The little girl that I killed didnt appear in the unblind spot screen, your honor"

    • You don't even need to move your head. If, your eyes are the average 63mm apart [wikipedia.org] and the A-pillar is 5 cm wide, located 50 cm from your eyes at a 20 degree offset from straight ahead, then your eyes have a relative separation of 63mm*cos(20 deg) = 59mm looking at things around the pillar while facing straight ahead. Lining up a triangle 59mm wide at the base which shrinks to 50mm at 50 cm distance yields a total triangle length of 3.28 meters. That is, the blind spot only extends 3.28 meters from your eye

      This is a solution in search of a problem.

      Do you have roundabouts in your country? Accidents where someone pulls out onto a roundabout having not seen or misjudged the speed of a car coming around it are not that uncommon. The A pillar blocking the driver's view is often a factor.

      Another roundabout related accident involving the A pillar is where someone indicates to turn off and the person next to them doesn't see their indicator light because it's obscured. This is another fairly common one.

    Please, Slashdot editors, stop posting OMG YOUTH INVENTS SOMETHING THAT HAS BAFFLED EVERYONE FOR CENTURIES stories. They, universally, are the result of someone without knowledge reporting on a near non-event, making it into something much larger than it actually is.

    That said, there ARE people who are young and really smart and are inspired to do great things that, by luck, they stumble upon despite decades of investigation by many, many people. These budding scientists, engineers, and entrepreneurs are to be celebrated. Regrettably, they are few and far between.

    And you know why? Because knowledge is power, and when you are in your teens, you haven't had enough time to amass enough knowledge to make substantial contributions to physics, engineering, biology, mathematics, or computer science, yet. These fields are just too advanced. We already know too much, and there are already too many people already looking at the same problems to make naive discovery possible except in rare cases.

    So, Slashdot editors, please, exercise a modicum of editorial prowess and curate these stories a tad better. Winning a science fair is indicative of talent, but is not in-and-of-itself newsworthy.
