Using a HUD to read/write texts/tweets? It seems like the creators missed all the studies about the dangers of distracted driving.

And pilots use HUD's so this must be safe? That would potentially hold water, if the pilots were using huds to tweet, text, and select music while landing... instead they're using huds to display important information...

I like the technology, I just don't like the suggested use cases for it...

As an optics guy, I was seriously considering building one of these myself. Awesome stuff. I'll be ordering...

I'm not an optics guy, but I'm an electronics hacker. How hard would it be to learn the basics to do it?

as a general hacker with an interest in learning whatever I can, I am also interested in how one would go about making one. it could be doable just onto a plain windshield, right?

Yes.

> it could be doable just onto a plain windshield, right?

My gut tells me you'd need some kind of reflecting sheet stuck in the windshield or the light would just go through. My guess is the screen in Navdy is actually reflecting light polarized in a specific angle, but I could be completely wrong.

Also, it would be harder because windshields are not planar nor perpendicular to the light source, which distorts the projected image. You'd have to calibrate it constantly, I guess that's why Navdy has a screen.

There's also the law. I believe you can't stick things to the windshield for safety reasons, specially if they occlude light.

It seems the optics might not be that hard: a mini-projector, a mirror (though I don't know why you wouldn't just project the light directly) and somewhere to reflect the light.

Just need to share my first reaction... Your hero image with an example of a HUD should probably not be a prompt to watch a video. That's just about the most dangerous thing that a HUD could ask you to do.

Agreed. After seeing this I assumed that this was a farce site.

WHY CAN'T PEOPLE JUST DRIVE?!?!! Why do they think they need to be reading and replying to SMS messages and emails and calls.

Just focus on the 1-3 tons of vehicle you're bimbling around in.

Maybe it's just me, but I just don't understand why drivers feel like they need to receive/respond to their call/text while they are driving. More often than not, someone other side won't realize I'm driving and see I can work out some magic until I tell them I'm driving. Because of this annoyance I've started ignoring any attempts to reach me while I'm driving. What would be cool service, actually would be the servi…

It annoys me as well but what I can I do? Example: I'm supposed to pick up my friend from the airport. I've got my wireless headphones on so he can call but he never does. He always texts. "Just landed", "Waiting for Luggage", "Coming out of the terminal". Of course he never tells me where :P I'd prefer he'd call since he knows I'm driving but since texting is the default for most people nowadays it's what they do fi…

Ah, I didn't realize that possibility. (What I have been doing in such case was just PTT through my headset that I am approaching so they can find me as I approach...)
