We have seen a peak birth-rate in recent years. Meanwhile more DSI (dysfunction of sensory integration) symptoms were observed from young children. The sensory integration is indeed very important for young children, but current relevant pedagogy seems too inadequate to train the sensory integration. Therefore, we designed an intelligent sensory integration training system DSIGame which employs many...
