DIESEL-X: A game-based tool for early risk detection of dyslexia in preschoolers

Abstract

DIESEL-X is a computer game that was developed to detect a high risk for developing dyslexia in preschoolers. The game includes three mini-games that test the player on three skills that are considered to yield outcome measures that predict the onset of dyslexia: the detection threshold of frequency modulated tones, a test on phonological awareness in which the player has to identify words that have the same phonetic ending, and a test on letter knowledge. In order to keep the motivation of the player high during testing, these tests are embedded in a computer game. We discuss the participatory design process that was adopted to design and develop the game, the rationale behind the design decisions, and we describe the resulting games.
