WeDRAW aims to mediate learning of primary school mathematical concepts, such as geometry and arithmetic, through the design, development and evaluation of multisensory serious games, using a combination of sensory interactive technologies. Working closely with schools, using participatory design techniques, the WeDRAW system will be embedded into the school curricula, and configurable by teachers. Besides application to typically developing children, a major goal is to examine this multisensory approach with visually impaired and dyslexic children.
