Children Designing Their Own P300 BCI Interface Choose Animation, Color and Sound
Thirty-eight typically developing children aged 8 to 12 used a design application to build their own picture-based interface for a P300 brain-computer interface augmentative and alternative communication (P300-BCI-AAC) system, in a study of what children themselves want from such interfaces. They consistently chose preferred colors, animation — zooming most of all — and sound cues: animation aided visual accessibility and target location, background color changes carried preferred colors into the display, and video GIFs and picture overlays added personal relevance. The authors call motion, color, personalization and visual clarity preliminary priorities for pediatric BCI-AAC design, and point to follow-up work with children who use AAC daily and with people who have motor difficulties.
