Developmental Dyslexia (DD) is a neurodevelopmental disorder affecting reading acquisition. DD cannot be diagnosed before starting the primary school; thereby, one of the main challenges is to obtain an early DD identification even during preschool years. Achieving this goal could help children at risk for DD to limit the impact of this disorder. To this aim, we have created a digital system composed of various serious games designed for predicting the risk of DD in preschoolers and potentially training specific skills impaired in this learning disability. Our set of serious games are designed to be accessible from any device, a computer with mouse and keyboard, but also a tablet with touch interface for younger children.
