Comunicació presentada a la 2014 conference on Interaction design and children celebrada a Aarhus (Dinamarca) del 17 al 20 de juny de 2014.

In recent years there has been an increasing awareness about the importance of involving children with special needs in the process of designing technology. Starting from this perspective, the paper presents the participatory design process carried out with children with autistic spectrum disorder for the design of a Kinect motionbased game aimed at fostering social initiation skills. By describing the strategies used for the design of the activities, we will suggest possible approaches aimed toward widening the space for contributions of children and including them at a more creative level. Within that, major emphasis will be dedicated to discussing the "empowering dimension" of participatory design activities as an instrument to enhance benefits both for design results and for the children themselves. Finally, the balance between structure and freedom in the design of the activities will be discussed.
