B-mail: A brain-controlled mail client

For centuries, humans fantasized about the idea of controlling objects only by thoughts. In the last decade, this idea has shifted from fantasy or science fiction to reality. Brain Computer Interfaces (BCI) have made this a reality. A BCI is a communication channel between the brain and a computer program or application. It allows the development of new applications that provide assistance to people with disabilities in regular everyday activities, making them accessible and easy to perform. We present in this paper a simple yet efficient email client which enables severely motor-disabled people to open, compose, send, reply and forward emails. It performs a real-time classification of user's brain activity signals using the P300 technique and performs the appropriate corresponding actions.
