Brain-Computer Interface

in-Computer Interfacing is an attention-grabbing, dynamic and highly inter-corrective explore issue at the interface between medicine, psychology, neurology, therapy-engineering, man-machine interaction, machine learning and signal processing.
BRAIN-COMPUTER INTERFACE SYSTEM :
In this system, Signals from the brain are acquired by electrodes on the scalp, the cortical surface, or from within the brain and are processed to extract specific signal features that reflect the user’s intent. Features are translated into commands that operate a device (e.g., a simple word processing program, a wheelchair, or a neuroprosthesis).
These BCI systems measure specific features of brain activity and translate them into
device control signals
BCI system
• Give answer of the simple questions rapidly
• Manage the environment
• Perform time-consuming word processing.
At the same time, the act of this new technology, measured in rate and accuracy, or in the complete measure, information transfer rate (i.e., bit rate), is self-effacing. Current systems can reach no more than 25 bits/min, even under finest conditions. The eventual value of this new technology will depend largely on the degree to which its information transfer rate can be increased.
