Portable mind-reader lets users write with their thoughts

from TGDaily:

The Mind Speller, intended primarily for people with severe motor disabilities, is an EEG-based device that interprets brain waves to spell words and phrases.

The Mind Speller contains a proprietary ultra-low power eight-channel EEG chip developed by IMEC and Holst Centre to process the EEG signals. A commercially available low power microcontroller digitizes the EEG signals, and a low power 2.4GHz radio transmits the EEG signals wirelessly to a nearby PC.
