Brain Port Tongue Interface
CNN has an article about a new interface that transmits images directly to the brain through a device placed on the tongue. The interface, known as the "Brain Port," has the potential to transfer data from cameras, compasses, sonar, etc. through electrodes on the device and into images in the user's brain. It is currently being developed for military applications, with an intent to create soldiers with "superhuman senses similar to owls, snakes and fish." At its current stage, the device has helped scuba divers locate small objects in controlled conditions and produced some visual perception for blind testers. Although it would be great for soldiers to have 360° sonar, it's a lot harder to call for help during the next shark, bear, or bear shark attack with giant plastic pacifiers in their mouths.
