Ambient Intelligence System of Agents for Knowledge-based and Integrated Services for Mobility Impaired Users
  image gallery  


- Mediation of services and content: in a pervasive, translucent, understandable (by ontologies) and managed (by web semantics) way
- seamless and efficient supply–demand matching (service negotiation, brokerage, etc.).
- Seamless environment management
- automatic adaptation of service content and layout (user interface) to user explicit preferences (user profile) and implicit preferences (history of use of service) as well as to the context of use (user location, travelling mode, scope of travel).
- optimised and innovative devices for both stationary and mobile communication giving access to the services and tools by addressing the appropriate senses.
- Flexible geo-referenced services combining multimodal travel information provision with pedestrian navigation on accessible routes, (outdoors & indoors) , according to the required level of accuracy by the user and the context of use.
- User confidence based environment (safety, reliability, security, privacy and usability).


- enhanced accuracy localisation,
- accessible intermodal route guidance modules and interfaces to e-Commerce and e-Payment,
- domotics,
- health and emergency management,
- driver support,
- computer accessibility,
- e-Working,
- e-Learning systems and assistive devices.

The ASK-IT integrated project aims at establish Ambient Intelligence (AmI) in semantic web enabled services, to support and promote the mobility of Mobility Impaired people, enabling the provision of personalised, self-configurable, intuitive and context-related applications and services and facilitating knowledge and content organisation and processing.

In its quest, to support the user in a holistic manner, ASK-IT focuses on geo-referenced and personalised transport and tourism services, which however are fully integrated to the home, work, leisure and sport, as well as the assistive technologies environments and devices. Emphasis is on seamless service provision, independent on the media, user location (i.e. indoors, outdoors, in a city, during a trip, etc.), user type and residual abilities.

The purpose of the Data Management Module (DMM) is to provide all required interfaces that will allow ASK-IT agents to constantly communicate with it. DMM adopts a service oriented approach for the realization of information search and retrieval capabilities. Specifically, supported services handled as web services within the DMM environment. Appropriate mechanisms are implemented internally to enable semantic matchmaking and capability-based search and retrieval. DMM hosts the required database to adequately index, store, manage and access available content and services. The core mechanism of the DMM is a service matchmaking mechanism for the discovery of ASK-IT supported services. Also, a set of interfaces are developed in order to establish communication with the ASK-IT ontology server, a service description repository and the actual services and content through appropriate protocols.

The ASK-IT Ontology Server realises the ASK-IT ontological framework. The Ontology Server is responsible for the implementation of the physical infrastructure that supports access, storage and maintenance of ASK-IT ontology. The Ontology Server is implemented as an ASK-IT software module, which is integrated into the Data Management Module. The communication interfaces allowing access to the ontology are defined in the form of SOAP Web Services.
