Not having a glow outside the vehicle is likely to be Too Damn Hard. Powering the thin film without introducing visible (even if faint) lines is highly likely to be problematic.
I very much doubt the underlying technology - especially on the thin film; everything else (cameras, eye tracking, etc) is probably close - is anywhere near ready. It'd be cool, though, I agree.

I did some requirements work on an FAA chip a few years ago. There were about 10,000 requirements...for this one chip...which would go into a board with other chips...which would be packaged with other avionics baords...just brew it! wrote:FAA (or FAA-like) safety certification can easily increase development costs by an order of magnitude or more.

It is projected onto the screen with optics in such a way that the reflection appears "distant" to the eye so there is no need to re-focus (projected at infinity). One of my co-workers worked on this in the late 90's/2000's, but I don't remember the specifics. With the technology at the time, it was VERY expensive.

the idea of having the windshield blocking incoming headlights is interesting but I'm not sure we are there yet especially given the litigious nature of society.
clone wrote:more moving parts is always a bad idea, on top of that focused beams that are constantly on the move will do nothing more than distract the driver.Why not just install computer-controlled spotlights that would come on automatically when a road obstruction is detected? I don't mean mere "shotgun styled brights" that broadly light up the whole road, blinding oncoming drivers. Instead, I'm suggesting that we deploy two articulating spots located at each front fender, each light being able to pan, focus, and zoom in or out on one or more figures in the road. That way we don't have to install i7 processors in our windshields and we don't have to worry about where to place the heatsinks.
keeping an eye on the vehicles ahead of you is only a part of the equation, drivers need to have a peripheral awareness that focused lights would destroy.
the answer is already in development, I've seen the demonstrations of it in action, the problem has always been cost.

That wouldn't really increase the processing or sensing demands, but it would eliminate the need for an $83,000 display, and it would be compatible with any car. You could also take it off if it decided to try to kill you.
The Egg wrote:This was my first thought. Rather than the windshield, some sort of transparent headset with a built-in HUD that also plugs into the car to communicate with exterior sensors and also display all the dash panel info. You could go a step further and create a beacon that Joggers/bikers put on their body to light them up in the HUD of drivers. Or maybe even some sort of integrated GPS? Dang Captain Ned, we should get together and start patenting!Melvar wrote:Two thoughts: First, why the windshield, and not a head mounted display (like Google Glass, but better)?

And Moose? Good god, that's terrifying.
And do you have anything that'll stop guard rails and jersey barriers from jumping out and hitting me?
