The "blind spot" phenomenon in a car can be a real bane for drivers. However, everything seems to indicate that a 14-year-old from the USA solved this problem for good.
A blind spot is often a place in the car that limits the driver's field of vision. This may be the point where the mirrors are unable to preview the entire area around the vehicle, it may also be a fragment obscured by one of the pillars.
It was this last problem that a gifted teenager by the name of Alain Gassler coped with. She built a prototype system consisting of a webcam and an ordinary projector. Everything works on an extremely simple principle of image transfer. The material recorded on an ongoing basis by the camera is sent to the projector, which in turn displays it in real-time on the "A-pillar" in the car. Thanks to this, the driver sees the image through the body element as if it did not exist at all.
Interestingly, the girl through the trial and error system even chose a special reflective material that focuses the image only towards the person leading. Passengers still see the usual finish of the car so they are not exposed to eye pain caused by a bright picture.
The idea itself is of course not revolutionary in any way. Car companies have been offering special blind spot sensors for years, and sometimes even use cameras that work on a similar principle. The mere fact, however, that the described project was entirely made by a teenage girl is already worth noting.
