Geometris: Designing Collaborative Mathematical Interactions For Children.

We present Geometris, a collaborative embodied geometry game for 6- to 11-year-old children. As shapes are projected onto the floor, players recreate those shapes on a 6x6 feet interactive mat. At the end of each level, a geometric pattern - the result of overlaying all created shapes - is displayed. Two dimensions of user interaction-mobility and division of labor-emerged during pilot gameplay sessions. We hypothesize that these interactions offer resources for children to learn geometry concepts as well as collaboration skills.
