ARIADNE aims to increase disabled and elderly people's mobility within buildings by enabling them to gain physical access, find their way about, and obtain information more easily. It will supply the architectural and technological infrastructure to provide an appropriate level of support. This involves the retrofitted installation of intelligent nodes at pertinent locations within a site. At the reception desk visitors would be provided with a smart card ID badge containing their requirements and an itinerary of the visit. Upon sensing a user arriving at a particular location the intelligent node will provide information, aurally, visually or electronically. The project developments will provide a cost-effective access and navigation solution for building operators, enabling a wide range of users to enjoy safe access to buildings.
