If this next-generation display technology developed by Asukanet ever gets past the concept stage, the days of huddling over a hole-in-the wall to block your balances from prying eyes could be over. With a viewing angle of just plus or minus 20 degrees, the Aerial Imaging Plate has a very specific sweet spot that ensures your private info stays private.
The display uses a focus-free pico projector aimed at a piece of glass that actually reflects the light twice, which ends up creating an optical illusion of an image floating in mid-air when you're standing directly in front of it. And with the addition of targeted sensors, the floating image can even be touched and interacted with.
So not only is it almost impossible for others to see what's on the display, there's no physical contact and no fingerprints left behind leaving clues about someone's PIN. Which would make a cash machine employing this technology incredibly safe to use, not to mention far more hygienic. [DigInfo TV]
