you’ll see it
you, you may eventually be able to use a personal HUD. A team under Babak Parviz at the University of Washington in the United States has devised a prototype for a contact lens that could one day beam HUD images straight into your eyes.
Active contact lenses would facilitate a related development called augmented reality. This is already available on some smartphones, where computergenerated graphics are overlaid on live video from the phone’s camera, turning the phone into a kind of magic lens on to the world. Information like directions, points of interest and even translations of signs augment the natural view. This is amazing on a hand-held, but with a HUD-capable contact lens the user could be immersed permanently in an augmented world, interfacing with digital devices around them.
It is hard to be sure whether HUDs are a fad or the future, but it seems likely they will find some place in our lives. So heads up!
Oh so cool: Canadian company Recon Instruments develops ski goggles with heads-up displays. Despite the fanciful speed (100kmh, left screen), these can include mapping displays (middle two screens) and video (right).
