Apparently Fraunhofer researchers are working on a teeny tiny pocket projector [Babel] which will be able to display stuff from PDAs etc on any available surface. Don’t hold yer breath waiting for this kind of tech to hit the streets, though, eh?. Just take a deep breath and remember the much hyped virtual keyboard.
‘A projector in the pocket size is in range: In it a mobile micro mirror develops the picture line for line. In laboratory prototypes researchers could increase its frequency of oscillation and dissolution so far that diagrams and texts appear clearly readable…Not much more largely than a piece wuerfelzucker could be the Beamer of the future. Built into Handys would always participate the mini projector – approximately for a PowerPoint presentation in the small circle or the fast view into an on-line journal. In strange cities it could facilitate orientation, by projecting simply a city plan to the next house wall.’
