In a second session, a subject specific acceptable pressure level is retrieved from the data of the first session and constantly applied for 30 min. In a first session, evenly distributed pressure is increased and afterwards decreased in fixed time intervals, going from 10 kPa to 30 kPa and vice versa with steps of 2 kPa. Levels of discomfort are assessed in twelve participants, wearing an EEG headset with controllable electrode pressure exerted at 14 locations. The present study is confined to the impact of adjustable electrodes pressure on level of user comfort only. Our research delivers a better understanding on the link between general level of comfort and possible useful clear data signals, that can be used in brain computer interfaces (BCI). The system is designed for use with dry electrodes. In this paper, we evaluate a prototype EEG headset that actively places electrodes at standardized positions on the subject’s head, where each electrode is applied with equal pressure. Such devices could induce medical and commercial applications. Development of dry electrodes offers the potential to develop wearable EEG headsets. The technique is traditionally applied in a clinical setting with EEG caps and conductive gels to ensure proper contact through a subject’s hair, and anticipate inter-subject anthropometric variations. N2 - Measuring and interpretation of brain wave signals through electroencephalography (EEG) is an emerging technology. T1 - Determining Comfortable Pressure Ranges for Wearable EEG Headsets Additional observation and surveys yields insights on user experience in wearing a pressure exerting EEG headset.", During this intervention, level of discomfort is assessed in a VAS-scale.
