The design of educational information systems has increased today, presenting new ways of carrying out educational problems. This article shows the development of a Brain Computer Interface Educational (BCIE) system capable of capturing, configuring and displaying in real time through a graphical signal interface (EEG) obtained through the MindWave Mobile device from NeuroSky, which captures brain signals and later the shipments via bluetooth to the embedded Raspberry Pi 3B+ system. The system allows attention values to be obtained when the student interacts with different activities. As a result, it was possible to obtain an interface embedded in a portable controller that allows to determine the attention profiles of students at the educational level.
