Diseño, desarrollo y evaluación de un sistema Brain Computer Interface (BCI) aplicado al control de dispositivos domóticos para mejorar la calidad de vida de las personas con grave discapacidad

Zusammenfassung

Objective: The aim of this study is to design, develop and assess an application for automatic control through the electroencephalogram (EEG) signal using a P300 evoked potentials-based Brain Computer Interface (BCI) system, in order to increase the autonomy of dependent people at home. Material and methods: An application for automatic control, by means the user�s EEG signal, through a P300- based BCI system was developed. The system was applied to nine subjects, users of the National Reference Center on Disability and Dependence from León (Spain). Results: Most of the subjects could control the application with an accuracy of 65% and upward. Three of them achieved even more than 85%. These results are significantly higher than the results achieved using a motor imagery-based BCI. Conclusions: P300-based systems require neither a training period nor an extremely high level of attention. Due to this reason, most of users were able to control suitably the developed application, which allows them to control devices at home, improving their independence and quality of life
