NPR's Andrea Seabrook talks to Dr. Steve Mann, a computer science engineer in Toronto, Canada, who may be the world's first "cyborg" -- part man, part machine. Mann has boosted his sensory abilities with special glasses and implanted sensors that enhance his perception of reality and give him constant biofeedback. He's the author of Cyborg: Digital Destiny and Human Possibility in the Age of the Wearable Computer and a pioneer in the field of cybernetics.
