Effect on cost

The Jabil developments sound great, Albrecht. How will they affect the cost of HUDs?

Looking down at the gauges

I've done a lot of roadracing "track days" in my car and on my motorcycles.  You can really notice how long it takes to look down at the dash in those situations. 

The instructors always say to make sure to check your dash when you enter a long straightaway, to make sure that you don't have any oil pressure or other problems. 

I definitely understand why racers use large, brightly colored lights attached to critical sensors, as you really can't be looking down at the dash when you're racing.

I've read about some new HUD setups for mototcycle helmets which I think is a neat idea.

HUD displays in some form or other will eventually find their way into consumer automobiles and motorcycles as the rule, not the exception,  So much valuable information presented in a manner that is easy to interpret.

Ideal Application for a DLP

It certainly makes more sense to have an HUD than the large LCD on the dashboard.  With the LCD becoming the norm in vehicles the cost of a DLP to drive the HUD should become irrelevant.  The last HUD I saw was an LCD embedded in the windshield, and that was a rather poor implementation because a good HUD needs to appear at the correct focusing distance as well as in the same field of view.  This looks like an ideal application for a DLP.

But what needs to be displayed, really?

The Jabil display sounds interesting indeed. But I am really thinking that most if the information on the instrument panel does not need to be presented there. Only warnings about deviations from where they should be. Possibly a GPS overlay indicating which lane to be in for the next turn, and where some targeted destination is. Best of all would be an IR camera overlay for use in fog or at night. But a gas gage and temp gage display when things are OK is a poor choice. A small pointer indicating speed could be handy sometimes, and som indication of vehicles in the blind areas along side could be quite handy. But never ever put any sound system or HVAC indicators in an HUD because those functions just don't rate that much attention.

I actually shuddered when I read this...

"What drivers really want are HUDs that project more types of information, including links to a vehicle's infotainment system."

 

Here's some food for thought:

Thanks for the link, Nancy. That article raises a good point: Taking your eyes off the road is a big problem, but cognitive distractions can be a big problem, too.

Sure it would be fun watching a movie or conversing through Skype on your HUD while driving but I thought the idea was to have an unobstructed field of view. Nancy makes a great point.
