The Brain Computer Interface (BCI) is a system that realizes a connection between the human brain and a controllable hardware, so it translates the brain activities to control commands, in order to control a TV, a videogame, a computer or in principle any controllable device. The BCI takes the mental activities recorded and measured by any means, for example electroencephalography (EEG), as inputs and converts them to meaningful signals for controlling the target device. Such a system is of an extreme importance for patients who suffer from paralysis, hemiplegia, neuromuscular diseases or any disability so that they are not able to communicate properly with the outer world any more, or that they lost completely or partly their ability to move and control the muscles voluntarily. With the help of BCI system these patients are able again to control and administrate their electrical devices without the external help they usually need from their keeper or attendant, and are capable of conveying their wishes and thoughts to their surroundings. In this talk we present a BCI system we designed for controlling a TV set remotely using the Emotiv EEG neuroheadset, for recording the EEG signals, and the real-time framework (KiRAT) which performs the demanded signal processing and outputs the corresponding control commands to the TV set.
