Brain-computer interface fatigue in children: mechanisms and impact (Master's thesis, University of Calgary, Calgary, Canada).

However, kids with severe physical disabilities such as quadriplegic cerebral palsy (QCP), are often unable to exercise such autonomy. Brain-computer interface (BCI) technology offer children with QCP unique opportunities for communication, environmental exploration, learning, and play. BCI research is rapidly developing but has neglected pediatric populations. Like many cognitively demanding tasks, fatigue is a critical factor to consider for BCI performance and enjoyment. BCI fatigue has been studied in adult populations, but there are no pediatric studies to date. Our prospective, cross over study assessed the effects of two BCI paradigms and a control condition on self-reported fatigue and electroencephalogram (EEG) biomarkers of fatigue. Thirty-two typically developing children aged 7-16 years participated in three sessions: motor imagery-BCI, P300-BCI, and film viewing (control). Self- reported fatigue and resting-state EEG alpha band power significantly increased across all sessions (p < 0.001; p = 0.047 respectively). These two measures of fatigue were uncorrelated to one another. No differences in fatigue development between sessions was observed. This project provides a baseline understanding of pediatric BCI fatigue. Short periods (30-mintues) of BCI use can increase self-reported fatigue and an EEG biomarker of fatigue. Performance was stable across BCI sessions and not associated with our measures of fatigue. The clinical implications and impact of fatigue on useability and enjoyment are unclear. Our results support the variability of fatigue and the overall BCI experience in children that warrant future investigation.enUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
