Adaptive Brain Interface

Adaptive Brain Interface

Abstract:


In simple words ABI can be defined as a human computer interface that accepts voluntary commands directly from the brain. The central aim of ABI is to extend the capabilities of physically impaired people. The brain-computer interface provides new ways for individuals to interact with their environment. The computer will continue to be a necessary component as long as detecting a brain response reliably remains a complex analytical task. In most cases, the brain response itself is not new, just the means of detecting it and applying it as a control. However, the necessary feedback associated with experimental trials frequently resulted in improved, or at least changed performance. Little is known about the long-term effects of such training either from an individual difference, or from a basic human physiology point of view.

A brain-computer interface (BCI) is a system that acquires and analyzes neural (brain) signals with the goal of creating a high bandwidth communications channel directly between the brain and the computer. The objective of the ABI project is to use EEG signals as an alternative means of interaction with computers. As such, the goal is to develop a brain-actuated mouse.

Introduction:

In today’s fast paced world, information and communication technologies are dramatically transforming industries, economies and the quality of our lives. Access to new emerging technologies can be taken for granted. Unfortunately, not everyone can enjoy the benefits provided by information and communication systems on equal terms. People with severe physical disabilities are practically excluded. But, what if they could communicate their wishes or control electronic appliances merely by thinking? After all, the most important part of our body that controls functioning of our body is our brain. We unnecessarily think that a person handicapped with his hands or legs cannot work on computer or even cannot control electronic appliances. So let’s make them utilize their brain to control computer or even turn on electrical appliances. The European Commission’s Joint Research Center (JRC) is coordinating a project called Adaptive Brain Interfaces (ABI) as part of European Union Information Technologies ESPRIT programme.
