Hi,
at
http://sta.jrc.it/abi
you can find info about the very interesting
Esprit Project Adaptive Brain Interfaces.

[ Moderator's note: here are the first three paragraphs from that web page:
"The objective of the ABI project is to use EEG signals as an
alternative means of interaction with computers. We seek to recognise
five mental states from on-line spontaneous EEG signals by means of
artificial neural networks, which are associated to simple
commands. For instance, to select an item from a computer screen it
suffices 5 mental states; four of them will move the pointer "up",
"down", "left", and "right", while the fifth pattern will "click" and
activate the item underneath the pointer.
We seek to build individual brain interfaces rather than universal
ones valid for everybody and forever. Our approach is based on a
mutual learning process whereby the individual user and the ABI are
coupled and adapt to each other: a neural network learns user-specific
EEG patterns describing the mental tasks while subjects learn to think
in such a way that they are better understood by their personal
interface. In other words, every single user chooses his/her most
natural mental tasks to concentrate on (e.g., relaxation,
visualisation, music composition, arithmetic, preparation of
movements) and also the preferred strategies to undertake those tasks.
Another concern of this project is the robust recognition of EEG
patterns outside laboratory settings. This presumes the existence of
an appropriate EEG equipment that should be compact, easy-to-use, and
suitable for deployment in natural environments. No such a commercial
EEG system exists, and we will manufacture an appropriate helmet with
integrated and amplified electrodes."
