Improving Accessibility for those with Impaired Mobility (I-AIM) University of Newcastle Upon Tyne (Transport Operations Research Group and Department of Child Health) Card Europe Newcastle City Council (City IT Services) Start: July 1999 Budget: 130K EQUAL 28.06.00 SJE:IAIM0600
I-AIM will….. • develop a device to fit to wheelchairs to aid navigation in complex public buildings and on street environments • utilise existing contactless smartcard infrastructure (providing cost effectiveness). • improve accessibility and social inclusion and thus overall quality of life for wheelchair users • integrate the design process with special needs research • enable service providers to comply with the DDA
I-AIM: the Navigation Device • consists of a simple visual display plus smartcard reader • interacts with a passive network of fixed contactless smartcards deployed as navigation nodes throughout a finite domain, rather than an active network of beacons • negotiates a suitable route to a predefined user destination
Functionality of Navigation Aid • navigator contains map of domain (passive nodes connected by links). Links have attributes of length and accessibility weighting (suitability to various users); • navigator is set to destination. It is placed in proximity of node establishing current location. Map is accessed and appropriate direction of progress for user is indicated on display; • tracking of progress is possible. Each node stores record of interrogation time and user identity.
Node/Reader Interface • a contact-card or close-coupled card interface is clearly not appropriate to I-AIM; • ‘proximity’ cards are the most widely available card technology at the moment - however card to reader range is limited to 10 cm; • ‘vicinity’ cards with a much greater range largely do not exist as a reliable technology at the moment.
