ABSTRACT
A Brain Computer Interface (BCI) is a communication system that translates brain signals into commands for a computer. BCI is a communication system that recognizes user’s command only from his or her brainwaves and reacts according to them. BCI (Brain Computer Interfaces) are systems enabling communication between a person and a computer without muscular intervention that is to say that only cerebral activity is used. In the world several millions of person with heavy neuromuscular handicap could benefit from those systems. The interaction between the computer and a disabled person can be done by a technique which will help a disabled person to communicate easily i.e. the P300 technique. The P300 signals are often used in virtual keyboard applications (“P300 speller”) in which users select alphabet successively. Whereas the EEG machine is used to capture the brainwave signal from the scalp. BCI allows user to control their environment by using neural activity of brain. In this paper we proposed P300 based BCI system for disabled people who are suffering from paralyses and comma. We are proposing an application system using P300 which will become a voice of disabled by implementing text to speech technology.
