Accessibility of non-trivial remote controlled models and toys

Nowadays there hardly exist accessible off the shelf toys for children and adults with disabilities. One group of non-trivial toys that are very interesting for people with physical disabilities are remote controlled (RC) models because the remotes can be easily exchanged by custom ones. If the controller is once adapted to the individual needs of a user, he can buy models in RC hobby shops without the need to adapt or modify it. This paper describes and discusses alternative control interfaces accessible for people with physical disabilities to accurately control model helicopters, airplanes boats or cars.
