Head Up Display

Head Up Displays (HUDs) are the favoured solution for fighter jets, and even some passenger aircraft, but their cost and complexity means their adoption in the automotive world has, until now, been the preserve of high end vehicles.

A HUD can display useful data in the drivers field of view. Using clever optics, the data is focussed so that it appears to float ahead of the vehicle and does not require the driver refocus as he would do when reading instruments.

Although they are no creeping in to the options list of a wider range of manufacturers, they're still expensive. Because they use LED's and optical projection the displays are limited to simple text and graphics and brightness is an issue.

But US company Macrovision is prototyping a HUD system that uses red, green and blue lasers rather than LEDs to 'paint' the data. This allows for complex graphics with more contrast and brightness plus colour.

It looks like a superb system and, with important data fed to the driver 'heads-up' so that attention remains on the road, it is a valuable aid to road safety. But production cost is still an issue that needs to be overcome.

One cheaper option for this is if you are driving at night, you can put an Android device with GPS on the dash running something like Ulysee Speedometer in HUD mode and it shows you your speed ;)

However, the above information is a lot more advanced, clearly ;)

I am not sure how well it would be used. If it could be setup for displaying routing information like a SatNav does now then it might help some of those people that prefer to have the device stuck somewhere inappropriate on the windscreen like they use now :o Rolling Eyes Rolling Eyes Laughing
