Brain-Computer Interface Communication Device for Handicapped Person

BCI (Brain-Computer Interfaces) encodes brain to allow for direct communication between persons brain and external devices. It records brain responses to stimuli and identify whether the present stimuli was relevant or irrelevant to intent of subject. Thus, implemented approach by presenting to subject a virtual keyboard such that parts of the keyboard flash for long time. Focus on a particular symbol on a keyboard and count its flashes.  Used machine learning algorithms, constructed a classifier that could reliably identify to choice a subject.  Also studied the resulting interfaces in terms of rate of information sending and receiving.
