Ellen Boudreaux was born in 1957, blind, autistic, and unable to walk until age four. After she began to walk, her parents noticed that she possessed an extraordinary spatial awareness.

As her spatial sense developed, Ellen was able to pinpoint the exact location of objects, such as fences and walls, up to a distance of six feet. She was also able to walk through thick forests without ever running into a single tree.
