Perspectives on user experience evaluation of brain-computer interfaces

Abstract

The research on brain-computer interfaces (BCIs) is pushing hard to bring technologies out of the lab and into society and onto the market. The nascent merge between the field of BCI and human-computer interaction (HCI) is paving the way for new applications such as BCI-controlled gaming. The evaluation or success of BCI technologies is often based on how accurate the control of a user is with the technology. However, while this is still key to its usability, other factors that influence the user experience (UX) can make or break a technology. In this paper we first review studies which investigated user experience with BCIs. Second, we will discuss how HCI approaches can contribute to the evaluation of BCIs. Finally, we propose to develop a standardized questionnaire for evaluating BCIs for entertainment purposes. © 2011 Springer-Verlag.
