A collaborative approach to the design and evaluation of an interactive learning tool for children with special educational needs

We have developed an educational software tool ( Aprendiendo ) to reinforce the learning process of children with special educational needs. This tool makes use of a variety of interactive technologies such as Embodied Conversational Agent and multimedia elements (video images from a WebCam, pictures and photos). In this paper we propose a multidisciplinary approach to system design and the evaluation of the users' experience, involving the engineers, teachers therapists and the children themselves, and combining Wizard-of-Oz with other techniques commonly employed in this educational context. We illustrate our approach with a real user evaluation of Aprendiendo 's emotions module.
