Brain with Computer Interface

Abstract :

The human brain is of the size of a deflated volleyball which weighs about 3 pounds. We live at a time when the disable are on the leading edge of a border societal trend towards the use of assistive technology known as Brain with Computer Interface. Brain-computer interface(BCI) is a collaboration between a brain and a device that enables signals from the brain to direct some external activity, such as control of a cursor or a prosthetic limb the interface enables the direct communications path way between the brain and object to be controlled. With the advent of miniature wireless tech, electronic gadgets have stepped up the invasion of the body through innovative techniques. Firstly this paper deals with has to how this mechanism is supported by the brain in the later section we describe its applications, current research on this technique, real life examples and concluding it with its advantages and drawbacks.

Introduction

A Brain-computer interface (BCI) provides a new communication channel between the human brain and the computer. The 100 billion neurons communicate via minute electrochemical impulses, shifting patterns sparking like fireflies on a summer evening, which produce movement, expression and words. Mental activity leads to changes of electrophysiological signals.
