This paper presents a service-oriented application whose purpose is to assist various activities of mobility impaired people as they move from one location to another. Such activities include trip planning, route guidance, e-working, e-learning, search for points of interest and social events among others. A number of registered web services provide all the required content and information that are displayed on the end-user device. Existing services are marked up by a number of domain ontologies about the information needs of mobility impaired users, in order to enable ontology-based search and retrieval of services. A service alignment tool has been developed to facilitate the markup process on behalf of service providers. After describing the architecture of the overall application and the involved mechanisms, we demonstrate a number of use cases that are enabled by the presented technologies.
