Belgian researchers from the European nanoelectronics and nano-technology research center Imec, Holst Centre, and Katholieke Universiteit in Leuven developed an EEG based writing system that may be helpful for people with severe disabilities.
The Mind Speller, though, seems very similar to University of Wisconsin-Madison’s communication tool we wrote about a year ago that flashes rows and columns of characters and monitors when the brain notices the character it wants to type.
It detects and interprets P300 event-related potentials in the EEG-signals of a person that is selecting characters from a display presenting alternate rows and columns of characters. P300 potentials are often used as metrics of cognitive function in decision making processes. However, currently available P300 devices are large, expensive and uncomfortable in use. Read more »
