Fuji Television demonstrates visible light communications system
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.
Matsushita demonstrates data beaming with visible light
Infrared hasn't exactly taken the wireless data transfer world by storm, and while it seems to still flank the sides of modern smartphones and the occasional laptop, we can't exactly recall the last time we found it particularly useful in a public setting. Matsushita is out to solve the data beaming quandary, and it's looking to add a little light to the situation all the while with a visible twist. The technology allows data to be beamed from transmitter to receiver via visible light, and aside from purportedly streaming information along at "optical fiber speeds," it can also pull double duty as an indoor lighting source if you're short on lamps. The firm is hoping to get the standard ratified soon, and ideally, would like to see kiosks set up to beam information onto consumer / client receivers by just walking up to the light source, pairing up their device, and walking away happy. Additionally, this system could have a leg up on other wireless alternatives in sensitive areas such as hospitals, as the Visible Light Communications (VLC) creation won't interfere with pulse-makers and other medical equipment. Now, how long before this stuff hits the handset market?[Via Gearfuse]
