| Summary: | Brain-Computer Interface (BCI) is an interface connecting the human neural system and computer. This article explains the fundamental principles of BCI and devices, which can be controlled using electroencephalography (EEG). Firstly, this article describes Brain-Computer interface according to obtaining brain activity. After that, the applications of BCI are proposed, which can be used in clinical practice. In the experimental part, the external systems are defined. These external systems are operated by BCI technology. This technology is developed at the Department of Informatics and Artificial Intelligence of the Faculty of Applied Informatics, Tomas Bata University in Zlin. This BCI system contains EEG technology, which is responsible for scanning a brain activity with a fourteen-channel device developed by Emotiv company. In the near future, this design of peripheral systems can be involved in clinical practice in various medical branches, especially physiotherapy.
