Last month, my
latest research paper entitled ‘Comparing interaction techniques for serious
games through brain-computer interfaces: A user perception evaluation study’
was published at the journal of ‘Entertainment Computing’. The paper is
co-authored with colleagues from Warwick University, University of Madeira and
Coventry University. It examines the application of commercial and non-invasive
electroencephalography (EEG)-based brain–computer (BCIs) interfaces with
serious games. Two different EEG-based BCI devices were used to fully control
the same serious game. The first device (NeuroSky MindSet) uses only a single
dry electrode and requires no calibration.
The second
device (Emotiv EPOC) uses 14 wet sensors requiring additional training of a
classifier. User testing was performed on both devices with sixty-two
participants measuring the player experience as well as key aspects of serious
games, primarily learnability, satisfaction, performance and effort. Recorded
feedback indicates that the current state of BCIs can be used in the future as
alternative game interfaces after familiarisation and in some cases
calibration. Comparative analysis showed significant differences between the
two devices. The first device provides more satisfaction to the players whereas
the second device is more effective in terms of adaptation and interaction with
the serious game.
