I got the VW marketing email and excitedly opened it hoping that it would reveal a lot more of the car, some more details of the specifications and trim, and even a hint at the price.

Nope, nothing useful as far as I could tell. My credit card has remained firmly undisturbed gathering dust!

For all I know the latest Eurofighters have ultra-modern multicoloured popup “toaster” screens like the Kona..
No, they're moving to building the HUD into the pilot's helmet instead. So it will be projected onto the helmet visor.

From BAE's website:
Indeed much of the advanced optical design and solid state image source technology has been applied to the next-generation Helmet-Mounted Displays (HMD) such as the STRIKER II helmet. The HMD effectively transfers the fixed HUD on to the pilot’s head with information projected directly onto the visor. Designed to be adaptable and boasting breakthrough advances in night vision and cutting-edge tracking technologies, STRIKER II helmet is expected to be used in the world’s most advanced jets for decades to come.



The HUD concept has also found its way into commercial use, benefitting millions of travellers as a standard feature in many modern civil aircraft and, increasingly, in the latest vehicles from brands like Mercedes and BMW. To date, BAE Systems has delivered over 14,500 HUDs.

Extremely clever but I do wonder if all the computer generated symbols obscure what you are actually looking at.

It's all based on the idea that the sensors can see things that the eye cannot. Meanwhile in the department down the corridor they are working on stealth technology to avoid detection by those very sensors.

The Mark 1 Eyeball is still difficult to beat IMHO.

If it’s like Hyundai’s idea of HUD which means projecting it on to a silly little popup piece of plastic then I’m not interested anyway...!
Someone please correct me if I'm wrong but any VAG product I have seen with a HUD it has been onto the windscreen.... so here's to hoping ;-)

I too am not a big fan of the popup ones but to be fair I have only experienced them on test drives. It seems somewhat inelegant, I presume it is considerably cheaper than onto the windscreen?

BMW seem to have both options as MINIs (and perhaps some BMWs?) have the pop up ones but BMW products have projection onto the windscreen.

I am under the impression it will be something like this

This is so cool and what I am hoping for but... I am not that hopeful. Considering how "normal" the steering wheel and screens are looking in the preproduction IDs I'm beginning to see this as rather unlikely. :-(

I think they're claiming the 'artists' impression HUD will be in the ID VIZZION. As that model is also the one where they claim you steer by hand gestures rather than using a steering wheel, and "To see the controls, you’ll need to put on a pair of mixed reality glasses" I rather doubt we'll be seeing anything like that any time soon.

Mind you, the projector headlight zebra crossing sounds rather fun.

I think that all the traditional HUDs on aircraft project onto an optically flat glass (?) plate not the not in a windscreen. Obviously not on a visor though.

Needless to say I will be pleased not to have to pay for an HUD if and when I get an ID3.

Intel had some glasses which project an image directly into your eye, they cancelled the project but it seems someone bought the tech:
North has acquired the patents and tech behind Intel’s Vaunt AR glasses

I think these would be quite interesting for drivers, and also for people with hearing difficulties as you could get live transcriptions discretely beamed into your eye

Someone in my family has a '67 plate Audi A4 with a HUD. I sat in it the other day, and the HUD is definitely usable, but what y'all probably don't realise unless you've sat in a live fighter jet, a real HUD is projected and focused much further away, i.e. not 2 feet in front of your face, because when you are going 600mph at 250' and looking where you are going to be in 2 seconds time, you don't want to be constantly refocusing your eyes in and out, they are not quick enough.
Now in a car, your focusing distance is usually dependent on your speed and environment say maybe between 20-250', but definitely not 2', you might as well stick to steam gauges). This is what I find is the biggest drawback of all of the car-based HUDs that I have seen. They're cool but they are still gimmicks IMO.

Yes they're just gimmicks in a car but there's no reason not to project the data images at infinity as they should be, surely.

The three I've used all focussed at infinity. Perhaps the Audi is a poor example?

The photo I posted above took me some time to get right, the phone kept trying to focus on the dashboard giving me a blurred picture, I had to force it to focus on the scenery in order to get the HUD in focus. If you look at that photo you'll see the dashboard and the HUD screen are out of focus, the background and the displayed image are in focus.

Here's an earlier attempt where the dashboard is in focus and the HUD and background are the ones out of focus:

Thank you for pointing that out - it was part of my objection but omitted to mention it as I thought that the cars without a plastic screen did provide this feature. However I realise this would depend on the projection source being buried deep in the dashboard..!

No, you use lenses to project a virtual image at infinity. The projector doesn't have to be more than a few inches from the screen.

The HUD in our 2010 Prius is projected onto the windscreen in the perfect position (it's fully adjustable for height and from side to side). I really miss it when driving our Kona Premium.

All the Prius' I've owned have had a windscreen projection mock HUD. Nothing at all like an A/C HUD, which uses specialised optics to project the imagery at infinity, so as to not interfere with the pilot's eye focus. The Prius mock HUD was a waste of space in my view, as you constantly have to refocus your eyes in order to read it, just as you would if glancing down at the instrument panel. The only time I ever used it was to display navigation arrows, and then only because that avoided having to look down at the central navigation screen. The eye focus change thing is a real PITA if you ever used a proper HUD or a monocular system like that used in the TADS/PNVS on the AH64. I'd happily do without a HUD in car until such time as the manufacturers get the infinite focus thing sorted (none have yet).

I guess we'll have to beg to differ there, but I think the two photos I posted demonstrate pretty clearly that the BMW HUD does focus at infinity. I agree that a HUD which doesn't do that wouldn't be worthwhile but the three I've used (BMW, Mazda, and Citroen) all did.

So far no car manufacturer makes a true HUD collimated to project at infinity AFAIK. Some manage to get a long enough optical path to get the image to appear to be part way down the bonnet, perhaps even towards the end of it, to reduce the amount of eye refocussing needed. The optics for a properly collimated holographic display are just too damned expensive for cars at the moment, as every ray path seen through the combiner has to be exactly parallel. Any deviation from parallel forces the eye to refocus in order to clearly read the projected image.

I've yet to see anything like a proper prism collimator/combiner panel in any car, most seem to either use a semi-transparent screen or project directly to the windscreen, relying on the partial internal reflection from the laminated glass to produce a mock HUD appearance. The photo's in this thread look nothing like a true infinity collimated HUD, either. Once you've sat behind a proper one for a few hundred hours the things fitted to cars seem to be just an annoying distraction.

Fine, but for those of us that don't fly fighter jets, the current state of in-car HUD is just so much better than having to look down at the dashboard. I may not know what I'm missing, but it's streets ahead of having to look down and refocus on the dashboard.
