A Japanese company has developed the world's first underwater communications device which allows divers to talk with one another via converting voice into light signals for transmission, according to the Asahi Shimbun Monday.

The i-MAJUN system by Okinawa-based Marine Comms Ryukyu uses a light-emitting diode (LED) flashlight with a special diving mask. The mask converts a diver's voice into blinking LED signals which are transmitted to another diver, where the signals are converted back into voice and played back through speakers in the mask.

Potential uses include helping novice divers with lessons or for professional use in deepwater exploration. Trials are also underway to convert hand movements by handicapped divers to these LED signals in order for them to communicate.

The device took six years to develop and retails for about 250,000 yen (US$2,500), the newspaper said.
