HUDs

After watching the ignition vid a thought occured to me... I do not understand why the symbology on HUDs in automotive applications is always so blocky and bold faced?

If you have a look at aircraft HUD symbology it is almost always made up of thin lines, characters and symbols (FLIR image overlays etc. being the exception). I know that there are technological/historic reasons for this (vector data driven crts) but I think it also makes a lot of sense since the purpose of a HUD is to provide a lot of information while obstructing the view of the outside world as little as possible.

In this regard, I would appreciate it if the Camaro HUD became the exception to the rule and at least offered an alternative a/c style symbology mode.

I don't think this is predominantly a cost issue. Of course, very thin lines would require a very high-resolution raster display to look good and artefact-free. But take a look at the 'RPM-segmented-circle' in the ignition vid: Replacing those solid blocks/segments with thin vertical or horizontal lines (like the airspeed or altitude tape gauges on an a/c HUD) would be a relatively simple software change - provided the display panel is actually of a raster type.

I believe aircraft use a vector type display (think Asteroids or Battlezone) and the HUDs in cars are just simple LEDs. A raster display can display anything. An LED can only light up in a fixed way (like a common digital clock).

An F-15 HUD is about the price of two SS Camaros

Originally, a/c HUDs were all vector type displays. Today there are also raster type HUDs and even hybrid ones (e.g. ECR Tornado).

I agree, if the display to be used in the camaro is not a raster type (it's definitely not vector), changing the symbology would mean a hardware redesign.

I think anyone would be impressed that there is a HUD in a Camaro no matter how it looks like. I do see your point though...

For right now, a HUD is a luxury item there isn't a need to improve on any resolution on those things for a car. The only way I see this happening is if the HUD displays more information than just speed.

Hey, I don't know about all this blocky-round-a/c-FLIR stuff, but I think it looks pretty cool and like that it will be available.

according to the Dealer IDL it will be available DEC 09.


as for the blocky/round/flir. I've worked on flir and such. those parts are usually pretty darn expensive because they are military rated. and to those companies rip off the goverment. but yea.

I will take the two SS's you can have the F15 hud!
I do hope that the hud is ready sooner than predicted, that would be a nice add, it could make me wait... I do not like to wait...
and I can return the GMC at the end of January 09 (end of smartbuy) I thought the Camaros would be around by then, back in Dec 2005.

image quality on HUD's will improve once it becomes standard for a segment of cars. In the mean time we will be able to get a blocky one on a camaro in about 17 months.

I bet that even if the prices were the same we would still get a blocky HUD because of demographics. The fighter pilots can be assumed to have near perfect vision and Camaro can only be assumed to passed the (very lax) drivers exam. We might see some adjustably someday, but until then expect a HUD that your parents can see easily.

Keep in mind that there is a slight difference in functionality... the car HUD is to provide you "coarse" information on speed etc so blocky is fine. The aircraft HUD needs to provide substantially more information and is quite dynamic... hence the need for the greater resolution and detail. Blocky will be fine for the auto world...

My two cents...
