Abstract-This study compared the suitability of consumer- grade wireless Electroencephalography (EEG) headsets to Brain computer interface (BCI) paradigms on open-source and in-house built applications. One participant performed ten tasks using two EEG devices, i.e., the Emotiv EPOC+ and Neuphony. The participant performs a 2-minute eye-close dand eye-open task comprising a resting EEG task.The resting EEG task was carried out to evaluate the signal quality of EEG signals. Subsequently, motor imageryandP300-based speller tasks were performed using open Vibe software for BCI. At the end, participant performed a P300-based 3*3 speller task for an in-house-built BCI application. Preliminary analysis revealed that raw EEG data from Emotiv EPOC+ had a higher SNR compared to Neuphony. However, by treating both sets of data through Independent Coponent Analysis (ICA), we found that the signal quality of Neuphony is on par with that of Emotiv EPOC+. Furthermore, accuracy in BCI application was comparable in both devices, demonstrating their suitability in BCI paradigms. This plethora of measurements gives a thorough comparison that encompasses several features of EEG data for BCI. Our findings indicatethat the Neuphony may be utilised effectively in BCI applications across research and clinical settings with comparable quality to the Emotiv EPOC+.Index Terms-WPT, Inductive and Capacitive power transfer technique, Far field techniques.
