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.
