heads up displays or Huds as they're more commonly referred to are display
units which allow the user to monitor important information on a display
without the distraction of well uh putting his or her head down okay so
admittedly the name wasn't inspired by any particularly outof thebox thinking
but while the name May suck Huds themselves are a revolutionary idea and
although many of you will quickly recognize heads up displays as the
interface showing you know how much health and Gordon Freeman has left after
clubbing 400 baby head crabs or whatever
really that's just fantasy and in the same way that truth is often Cooler Than
Fiction the origin of Hud technology is
actually derived from jet fighters even better now to be clear they weren't as
advanced as what you'll find on your collector's edition Master Chief helmet
that was totally worth the $13 you spent on it but rather they were based roughly
off an old airman's machine gun reflector site which illuminated a
Target in the site when properly aligned this technique was eventually adapted By
Her Majesty's Royal Air Force in the early' 40s and adopted to use cathode
ray tubes and phosphorous coated TV screens you know like the one your
grandma still has to allow night Pilots to monitor targets directly via HUD
radar and then well from there on the
seals never really stood a chance did they second gen units instead use solid
light such as from LEDs to project images onto a pilot's wind screen from
an LCD display and are commonly found on Commercial aircraft but due to their
cost at the time were unlikely to be found in consumer goods like cars third
gen Huds on the other hand don't require projection at all anymore but instead
utilize a specially coated viewing surface and a doad called an optical
wave guide which manipulates visual light spectrum waves whatever the pants
that means allowing folks like automakers to display readouts like
speed GPS navigation uh music controls
or even like web content directly onto their proprietary HUD systems on the
windshield which finally brings us to fourth gen systems which use lasers to
display highdefinition images directly onto clear surfaces like that suet
interface and Minority Report potentially making them very compact
portable and versatile but heads up displays aren't just useful when
operating a vehicle or solving future crime in fact there's an Ever growing
list of programs which in essence transform a person's smartphone camera
into a miniature HUD and you know while
yes technically any display that sits right in front of your face so you don't
have to put your head down is technically a HUD most of them are better implemented than that and that
allows people to see information about local hotpots Museum exist exhibits or
even the Plenty of Fish profiles of passers by as they walk down the street
and as this technology continues to develop be that in the form of laser
displays uh transparent OLED displays holographic displays or even head
mounted displays that have a screen to show you the virtual stuff with cameras
mounted to the front for the view of real life more and more people will be
able to enjoy the benefit of access to information without the use of their
hands and assuming all goes according to plan this will even be possible without
having to wear something that makes you look and feel like a total early adopter
glass hole but what if we lived in a world where you didn't have to go out in
public at all to get your razors and other bathroom supplies shipped directly
