Indendix EEG lets you type with your brain

Austrian biomedical firm Guger Technologies is promoting a new electroencephalography (EEG) device that lets users type with their minds, calling it the world's first commercial brain-machine interface for personal use.

Consisting of an EEG cap, display, and computer, Intendix is designed for severely disabled patients and people with symptoms of locked-in syndrome, a condition (featured in the movie "The Diving Bell and the Butterfly") in which patients suffer near-total paralysis while their minds continue to function normally.

After only 10 minutes of training, most patients can type 5-10 characters per minute by focusing on each character on the display, according to Guger. Users count the number of times a letter flashes on the display, and the EEG cap picks up the related electrical activity through the surface of the skin.

Brain signals have also been used to operate humanoid robots, with the eventual goal of routing them through EEG devices and computers to enable people with paralyzed legs to walk. The nascent BCI X Prize aims to further brain-computer interface (BCI) development.
