Usability of EEG Systems: User Experience Study

Abstract

In recent years there was a change in EEG experimental designs - from simple behavior in the lab to complex behavior outside. That change required also an adjustment of EEG systems -- from being static and sensitive to mobile and noise-resistant. The rapid technological development has to balance performance (e.g. number of channels, low impedance contact) with usability (e.g. comfort for the participant, contact pressure, wet/dry electrodes) and mobility (e.g. wiring, weight). This has led to wide variety of designs which differ widely in properties. Here we compare 7 EEG systems with respect to the participant's user experience. Results demonstrate that from perspective of user experience of participants, mobile wet system (Cwet) had the highest score.
