Mind control making life with ALS better (pictures)
Using cutting-edge technology that reads brain waves, patients with ALS are regaining some control of their lives.
The state of care for ALS
ALS patient Eric Valor in his bed in Aptos, Calif. While his brain remains sharp, he can't carry out most functions on his own since becoming paralyzed by the condition, also known as Lou Gehrig's Disease.
Using current state-of-the-art eye tracking technology, Valor can "speak" by looking at, and pausing very briefly on, a letter displayed in a matrix on his monitor. This lets him build words and sentences that are then spoken by his computer.
