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.
Valor took part in an experimental project this year that successfully used a wireless headset that reads brain waves to allow him to request medical help and control the lights or television simply by thinking commands.
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.
This monitor, mounted above Valor's bed, provides the keyboard and screen with which he can interact.
A wearable headset, along with an app co-developed by Philips and Accenture, processes brain signals to control on/off switches linked to devices such as a television or lights.

Brain commands, simple thoughts calibrated to the specific user, can perform tasks like turning lights on and off and even dimming them.
The brain control EEG technology interface has the power to give ALS patients back some of their freedom, says Eric Valor.
