The Brain Computer Interface (BCI), called also often a Mind Machine Interface (MMI), or in other cases called a Brain Machine Interface (BMI), is a direct communication link or a communication pathway between the human brain and an external device. In case of the BCI system, user’s communication channels do not rely on peripheral nerves and muscles. Brain computer interface (BCI) systems offer communication and control capabilities to people with severe disabilities. BCI’s use electroencephalographic (EEG) signals recorded from scalp to control computer cursor movement, select letters or icons on the screen, etc.; but there exist other invasive methods too to record the brain’s activity. One example of BCI application is the EEG-based braincontrolled mobile robots, that can serve as powerful aids for severely disabled people, especially people with locked in syndrome in their daily life, to help them move voluntarily and communicate with the external world.
