New device allows the blind to ‘see’ with their tongues

Fascinating work being done at Dr. William Seiple at Lighthouse International in New York City. This device uses a patch that sits on the tongue, and vibrates in different ways depending on what the camera mounted on the glasses picks up. With training, one can “teach” the brain to pick up visual images based on the vibration being received.

This device can an even be used by people who have been blind from birth.
