Brain Computer
Interaction
INTRODUCTION
Brain Computer Interface is a direct communication pathway between brain and an external device.
Richard Caton was the pioneer who discovered electrical signals on the surface of animal brains through his path-breaking research.
Brain signals such as the EEG suggested the possibility of non-muscular communication and control, consummated through a BCI.
Factors influencing BCI
BCI supports the emerging needs of
people affected with ALS, brain stem
stroke etc.
Recent strides in measurement of
EEG in tandem with brain activity
research in humans and animals.
Factors Continued
Evolution of low cost hardware that allows complex real-time analysis of brain activity.
The recent surge in BCI research is new recognition of the extravagant adaptive capacities of the central nervous system.
What is a BCI?
A BCI is a communication and control system that establishes real-time interaction with the user and outside world.
BCI does not depend in any way on the brain’s normal neuromuscular output channels.
How does BCI work?
It works on interaction of two adaptive controllers:
1) The user, who generates brain signals that encodes intent.
2) BCI system, that must translate the received signals into commands that perseveres the user’s intent.
3)BCI usage is a skill-oriented tactic which user and system should acquire and maintain.

BCI systems would certainly need an
adept futuristic enhancement because
of them being slow.
The users are to amass a specific
domain of skills , taking all the
miniature aspects into consideration.
Over dealing with CNS involves many
potential risks and any malfunction
could result in chronic disorders.
Conclusion:
The research primarily focuses on
developing new augmentative
communication and control technology
It gives modus operandi for those
who suffer from severe neuro-
muscular disorders, such as ALS,
brain stem stroke and spinal cord
afflictions.
A tribute to Richard Caton , a pioneer
in marking the advent of BCI.
