At least one in ten children suffers from a reading and spelling disorder (LRS), also known as dyslexia. It has long been known that this disorder has nothing to do with limited intelligence. Nevertheless, LRS is often a great burden for the children and adults affected by it, which can lead to severe depression. The online learning program Orthograph, the basics of which were jointly developed in 2007 by computer scientists from the ETH and neuropsychologists from the University of Zurich, offers itself as a help to overcome or at least mitigate an LRS. With its playful character, it is primarily aimed at school children, but can also be used by adults. The program specifically supports the development of the brain regions that are elementarily important for writing and language. It links letters and words with different sensory stimuli (colours, shapes, sounds). This multisensory approach promotes the storage of new information and makes it easier for the brain to recognize patterns. Since a 2019/20 fundamental redesign of Orthograph, the learning app also includes a reward program called “Theme Park” modelled after popular computer games. This gamification enhances the app’s appeal and helps motivate children to engage in intensive practice.
