BrainPort Lets the Blind "See" With Their Tongues 131
Hugh Pickens writes "Scientific American reports that a new device called 'BrainPort' aims to restore the experience of vision for the blind and visually impaired by relying on the nerves on the tongue's surface to send light signals to the brain. BrainPort collects visual data through a small digital video camera and converts the signal into electrical pulses sent to the tongue via a 'lollipop' that sits directly on the tongue, where densely packed nerves receive the incoming electrical signals. White pixels yield a strong electrical pulse and the electrodes spatially correlate with the pixels, so that if the camera detects light fixtures in the middle of a dark hallway, electrical stimulations will occur along the center of the tongue. Within 15 minutes of using the device, blind people can begin interpreting spatial information. 'At first, I was amazed at what the device could do,' says research director William Seiple. 'One guy started to cry when he saw his first letter.'" There is some indication that the signals from the tongue are processed by the visual cortex. The company developing the BrainPort will submit it to the FDA for approval later this month, and it could be on sale (for around $10,000) by the end of the year.

Sure, the resolution won't be as fine but it will be a lot less obtrusive to wear a sensor wrapped around your torso than to have something on your tongue with a wire sticking out of your mouth.
A practical version of that sensor net the blind lady wore on Star Trek back in the '60s will likely be on the market before 2067, assuming technology doesn't leapfrog it entirely.
From TFA:
The key to the device may be its utilization of the tongue, which seems to be an ideal organ for sensing electrical current. Saliva there functions as a good conductor, Seiple said. Also it might help that the tongue's nerve fibers are densely packaged and that these fibers are closer to the tongue's surface relative to other touch organs. (The surfaces of fingers, for example, are covered with a layer of dead cells called stratum corneum.)
