Abstract
Emerging technology for brain-state monitoring offers the possibility to conduct measurements outside the laboratory. However, user-experience research is lacking. In this article, we present and test an approach for determining the development of user experience in the course of time using the so-called cross-modality matching (CMM). We conducted experiments with 24 subjects and evaluated seven mobile electroencephalography (EEG) devices. Using the CMM method, we registered the headset pressure of the EEG devices and subject's mood. We are able to identify a correlation between headset pressure and mood and to observe time trends. Subjects rated the heaviest, pin-based device as less comfortable in the course of time. The gel-based EEG cap is the most comfortable device regarding its long-time properties. The CMM approach for user-experience evaluation of new EEG technologies is direct, rapid, and easy to perform. This fact creates new opportunities for future studies in the field of user experience and human factors.
Highlights
R EGISTRATION of brain activity by means of electroencephalography (EEG) outside the lab is of increasing interest and coupled with various challenges
We used the logarithms of the relative grip-force values and proceeded as described in the ASSESSED BY cross-modality matching (CMM) ACROSS REGISTRATION POINTS AND DEVICES
Our first hypothesis assumed that headset pressure would increase in the course of time for all devices and subject’s current mood would become worse
Summary
R EGISTRATION of brain activity by means of electroencephalography (EEG) outside the lab is of increasing interest and coupled with various challenges. Mobile and easier to use EEG devices are emerging. They make use of wireless signal transmission and allow the subject to move more freely. The wearing comfort of the new devices is still unknown, as well as whether user acceptance is improved relative to traditional EEG acquisition. For the use of the devices in future studies, it is of major importance that they do not cause head pressure, discomfort issues, or alter subject’s mood state. This is important if the subjects are asked to wear the device for a longer period of time.
