Sc@ut:: Platform for communication in ubiquitous and adaptive environments applied for children with autism

Augmentative and Alternative Communication Systems (AAC) are an emergent technology for improving the,social integration of people with temporary or permanent communication difficulties. One problem which arises is the need to adapt these systems to the different users and situations by taking their capabilities, skills and progress into account. In this regard, we propose an adaptive architecture on a ubiquitous computation paradigm, which is being applied for children with autism. This paper proposes a two-tier architecture consisting of a communicator and, a context meta-model. It allows child communication to be represented and controlled using a PDA device by means of a wireless network. The main aim of the architecture is to facilitate communication, adapting to changes in user and scenario.
