An Augmentative Communication System Based on Adaptive Evolutionary Hypermedia Systems
Abstract
This paper focuses on improving ACS (Augmentive Communication Systems) by means of an adaptive evolutionary hypermedia. One of the most important features of our approach is the separation of the different aspects involved in the development, use and maintenance of the communication system. Concerning the knowledge representation aspect we use an ontology model that permits specifying the semantic of the represented reality. Regarding the presentation aspect, in order to generate the hypermedia structures we provide a mechanism that allows the creation of different views of the global knowledge model. About the navigation aspect it is important to emphasise its multimodal facet: at the technology level (PC or PDA) and at the interaction level (depending on the access restrictions and the selection units). The user adaptation aspect permits to analyse and to personalise the user navigation using his user profile, his user model and a set of appropriate adaptive methods. In addition, during the whole process we apply an evolutionary mechanism to evolve these aspects in an integral form.
