User’s Emotions and Usability Study of a Brain-Computer Interface Applied to People with Cerebral Palsy

People with motor and communication disorders face serious challenges in interacting with computers. To enhance this functionality, new human-computer interfaces are being studied. In this work, a brain-computer interface based on the Emotiv Epoc is used to analyze human-computer interactions in cases of cerebral palsy. The Phrase-Composer software was developed to interact with the brain-computer interface. A system usability evaluation was carried out with the participation of three specialists from The Fundação Catarinense de Educação especial (FCEE) and four cerebral palsy volunteers. Even though the System Usability Scale (SUS) score was acceptable, several challenges remain. Raw electroencephalography (EEG) data were also analyzed in order to assess the user’s emotions during their interaction with the communication device. This study brings new evidences about human-computer interaction related to individuals with cerebral palsy
