Motivation
Insufficient information accessibility Information overwhelming Demand for contextual information
and context aware applications
Intelligent environments
Faculty of Informatics and Information Technologies Slovak University of Technology
Target group:Visually impaired people
Substantial social impact Worldwide 161 million people suffer from
significant visual disability 37 million people are totally blind
Total lack of information Sight provides 90% of information
Need for information Independence Peace of mind Quality of life
Faculty of Informatics and Information Technologies Slovak University of Technology
Visually impaired people:Problems and issues
Dependency on the help of others Getting generic information Shopping Timetables
Asking “the darkness” Dangers
Obstacles undetectable with a cane Warning signs

Case study I – Visiting a doctor
A blind person visits a hospital She listens to office locations,
numbers and doctor’s names She does not slip on wet floors She knows the locations of lifts,
toilets, shops, wending machines, …

Case study II – National park
A blind person visits a national park He knows the locations of various
sights and amenities He listens to information guides
automatically at the correct places He receives information about
souvenir shops

Requirements / Prerequisites
Light, small and convenient client device Low implementation costs Low power needs, low latency Ubiquitous operation using existing
infrastructure Association of information with real-world
entities Dynamic messages Interface suitable both for visually
impaired and sighted users
Faculty of Informatics and Information Technologies Slovak University of Technology
System overview
Contextual information Entities (objects / “ideas”) RFID tags Messages (information)
Users Visually impaired Sighted

What is an RFID tag?
System operation
Faculty of Informatics and Information Technologies Slovak University of Technology
Messages
Message categories Critical messages alert of danger Message cache
Lowers latency and power consumption Enables operation without internet
connectivity Dynamic message content
Faculty of Informatics and Information Technologies Slovak University of Technology
Messages II
Contextual Information Description Language (CIDL) Validity Structured messages
Extensibility Support for different languages Links to multimedia/web content

RFID Name and RFID Tag service
RNS translates tag data to RTS server addresses Tag migration
RTS supplies messages RTS hosting
Central authority oversees RNS servers Abuse of critical messages Updates
Faculty of Informatics and Information Technologies Slovak University of Technology
Personalization and customization
Operation modes Message category priorities
Too many tags nearby Message filters
Repeating of irrelevant messages Rogue messages – SPAM
Notifications User interfaces

Marketability / Deployment
Early adopters Local authorities, Blind associations Mobile operators
Advantages Low cost of RFID tags No in-place infrastructure required Extensibility to applications for sighted users Might also use existing RFID tags
What is/might be needed? Affordable PDAs / Smartphones Integrated RFID readers RFID tag dispensers RNS authority, RTS providers
Faculty of Informatics and Information Technologies Slovak University of Technology
Summary
RFID tags associate information with real-world entities/objects
Relevant contextual information at the place you need it at the time you need it in the form you need
A higher quality of life for both the blind and the sighted
