Blind sight: The next generation of sensory substitution technology

Conventional wisdom says that you see with your eyes. But new technology is changing the way we think about sensation and perception, showing that instead of relying on these orbs for vision, we instead really see using the activity in our brains.

My newest piece for Discover Magazine explores three amazing devices that are restoring sight to the blind, circumventing the malfunctioning sensory organs and tapping into the healthy neuro-circuitry underneath. High-tech computers in Google Glass-like devices are converting visual information into auditory and tactile stimuli, allowing the blind to see, drive, navigate, and mountain climb using their ears, fingertips, and even their tongues, the brain translating this information back to the visual cortex.

Check out the full piece here, including a video of one of the devices in action.
