This paper describes and discusses the development of mobile exergames for children with cerebral palsy. The design process was built on codesign, and resulted in three activity games, two augmented reality (AR) games and one GPS based game. The resulting activity games were evaluated by 8 persons with cerebral palsy (CP). To complement this evaluation, the games have been evaluated against existing guidelines for accessible games. The developed games provide a proof of concept of how mobile games can be designed to encourage physical activity for children with mobility impairments.
