The Tongue As An Interface

Tech-heads and SF writers have been talking about human-machine interfaces for years. In a weird new twist on this idea, military researchers are developing just such a system – but one that uses the tongue to connect the brain to the external signals. This device is being used to allow deep sea divers a 360 degree field of view and sonar-like information about their environment, and there is work beginning on an infra-red version for soldiers.
