New paradigm for fast, adaptive mind spelling using non-invasive brain-computer interfacing.

Brain-Computer Interfaces (BCIs) are able to create a
communication-pathway between the brain and a computer by directly
reading out brain-activity. Characterizing for these BCIs, is that
muscular activity is bypassed, in contrary to normal interaction
between the brain and a computer. In this way BCIs can improve the
quality of life of patients suffering from motor impairment
significantly. The BCI proposed in this project in non-invasive: via
electrodes on the scalp, brain-activity is measured (EEG). This makes
the interfaces more user-friendly then invasive BCI's (where electrodes
are surgically implanted), but the signal-to-noise ratio is relatively
low. There is thus need forintelligent stimulation-paradigms which are
able to increase the information-transfer-rate. This project in
specific, looks for a fast and adaptive paradigm for Mind Spelling:
