A Tangible Math Game for Visually Impaired Children

We present iCETA, an inclusive interactive system for math learning, that enables children to autonomously engage and solve additive composition tasks. It was designed through a set of participatory sessions with visually impaired children and their educators, and supports math learning through the combination of tangible interaction with haptic and auditory feedback. Tangible blocks representing numbers 1 to 5 were used to add or subtract and correctly solve the task embedded in a computerized game. Our approach aims to provide better scaffolding for understanding the abstract concept of a number by working with different representations of that number, as the size of the block, Braille, color and audio feedback.
