This poster presentation will give examples of different software, developed in Sweden, used with young disabled children. The result of using this kind of software gives the child an opportunity to play on their own, to bee amused and it also gives the child practice in communication and skill training. The response of the software will keep the child motivated and has to be designed differently according to the developmental level of the child and its possibilities to see and hear the response. There are also a number of environmental and ergonomic factors that are of vital importance when working with young disabled children and software. For many of these children correct seating and physical support is crucial, as the position of the input device.
