Brain Computer Interface Technology & Its Modern Applications

The possibility to establish a direct communication and control channel between the human brain and computers or robots was a topic of scientific speculation for many years. Research in this area has undergone an explosive growth in recent years using a variety of brain signals, signal features and translational algorithms. Successful operation of the system depends on the interaction of two adaptive controllers: the user, who creates specific brain signals that encode intent and the BCI that translates these signals into output that accomplishes the user's intent. BCI can enable a person suffering from paralysis to write a book or control a motorized wheelchair or prosthetic limb through thought alone. But yet we have many thing to do and the technology has remarkable possibilities and within the coming few years, scientists working in the field strongly believe to get a great success for helping the society through new developments of techniques and instrumentation.
