- EEG correlates of video game experience and user profile in motor-imagery-based brain–computer interactionPublication . Vourvopoulos, Athanasios; Bermúdez i Badia, Sergi; Liarokapis, FotisThrough the use of brain–computer interfaces (BCIs), neurogames have become increasingly more advanced by incorporating immersive virtual environments and 3D worlds. However, training both the user and the systemrequireslongandrepetitivetrialsresultinginfatigueand lowperformance.Moreover,manyusersareunabletovoluntarilymodulatetheamplitudeoftheirbrainactivitytocontrol theneurofeedbackloop.Inthisstudy,wearefocusingonthe effect that gaming experience has in brain activity modulation as an attempt to systematically identify the elements that contribute to high BCI control and to be utilized in neurogamedesign.Basedonthecurrentliterature,wearguethat experienced gamers could have better performance in BCI trainingduetoenhancedsensorimotorlearningderivedfrom gaming. To investigate this, two experimental studies were conducted with 20 participants overall, undergoing 3 BCI sessions,resultingin88EEGdatasets.Resultsindicate(a)an effectfrombothdemographicandgamingexperiencedatato theactivitypatternsofEEGrhythms,and(b)increasedgamingexperiencemightnotincreasesignificantlyperformance, but it could provide faster learning for ‘Hardcore’ gamers.
