Designing for Engaging BCI Training: A Jigsaw Puzzle

Brain-computer interface (BCI) technology translates brain activity to machine-intelligible patterns, thus serving as input \"device\" to computers. BCI training games make the process of acquiring training data for the machine learning more engaging for the users. In this work, we discuss the design space for BCIraining games based on existing literature, and a training game in form of a Jigsaw Puzzle. The game was trialled with four cerebral palsy patients. All patients were very acceptant of the involved technology, which, we argue, relates back to the concept of BCI training games plus the adaptations we made. On the other hand, the data quality was unsatisfactory. Hence, in future work both concept and implementation need to be finetuned to achieve a balance between user acceptance and data quality.
