A Low cost Brain Computer Interface Module and EEG Analysis Using MATLAB

Abstract: A brain-computer interface, or BCI, is a modality for human-computer interaction whereby a person may control an external device using brain signals without muscular intervention. One of the most widely used signals is the electroencephalogram (EEG), since it has excellent temporal resolution, can be measured non-invasively, and is comparatively inexpensive and simple to acquire. The design itself is based on three main components: an Analog Front End, a Microcontroller, and data acquisition and classification system (software). This work will show that by interfacing these three main embedded devices, the results of a proven clinical EEG system can be replicated.
