It's not like visible light communications
is the new kid on the block or anything, but Fuji Television was busy showcasing a new flavor of the technology at Inter BEE 2007 that could assist deaf / hearing impaired individuals when watching TV. In the demonstration, a LED-backlit LCD TV displayed content while simultaneously beaming out information sans wires to a nearby PDA; the handheld was able to receive the textual data and display words to accompany the on-screen action. Not surprisingly, the communications system was developed by NEC
, and it even supported selective distribution in order to transmit the correct information to the appropriate individual. No mention was made of an expected commercialization date, but feel free to check out a couple more shots of the setup after the break.
