Communication through visible light has a new device : The Commulight Location System (Tantrik Baba has found a new use for his old torch !!)

Japanese firm Outstanding Technology has developed a Commulight location system, which relies on a pair of receivers to get smartphones and tablets downloading information using photons instead of radio waves.
One dongle is of the USB variety, but since most mobile gadgets lack such a socket, there's another that plugs into any device's 3.5mm jack. Each employs a sensor that grabs relevant location-based info from an overhead data-transmitting LED light.
According to its maker, Commulight's makers have proposed to use it as a as a way to give museum goers exhibit info, to transmit coupons, and even provide precision indoor location services more accurate than GPS or WiFi.
