Toward Inexpensive and Practical Brain Computer Interface

Brain Computer Interface (BCI) introduces a new communication system that does not depend on brain´s normal output pathways. This paper studies the feasibility of using inexpensive Electroencephalogram(EEG) device for BCI with asynchronous BCI mode which leads the control mechanism to become highly available for variety of users and a more natural way to communicate than the current BCI versions which depend on expensive EEG devices, which are less practical where they need special environment to run the BCI system, and use synchronous BCI mode in most cases. Benchmarking the results using Emotiv to another complex EEG device (BrainAmp) shows the reliability of such inexpensive devices.
