Thread: H.U.D Display

it's a "heads up display"....best example I can think of would be some Corvettes that have it, it projects data (an image) onto the windshield so you don't have to take your eyes from the road.

I had this idea too - it could be done but would take a lot of work

One major problem seems to be that if you project onto the windscreen you will get a 'double image' - where the image reflects off the inside and the outside of the glass.

The corvette gets round this by having a plastic rectangle that sits over the part of the screen where ther image is displayed. From what I have heard this can be quite annoying.

The new beemers solve it by having a plastic insert through the middle of the entire screen. Probably good but big $$$ no doubt!!

Another major problem is getting the thing to work evenly day, night, rain, bright sunshine, through tunnels etc. etc. That seems to be something which would require a lot of tweaking.

I think it would be cool for a carputer though maybe if one of those 2x20 LCD displays would be the best candidate. Or a more graphical display. You wouldn't want too much information - perhaps nav directions, speed, shift light...
