  1. GOING BEYONDTHE VISION LOSS BOUNDARIES Michal Tvarožek, Martin Adam, Michal Barla, Peter Sivák, Mentor: Prof. Mária Bieliková

  2. Presentation outline • Motivation • Case studies • SPOT-IT system overview • Marketability / Deployment • Summary Faculty of Informatics and Information Technologies Slovak University of Technology

  3. 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

  4. 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

  5. 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 Faculty of Informatics and Information Technologies Slovak University of Technology

  6. 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, … Faculty of Informatics and Information Technologies Slovak University of Technology

  7. 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 Faculty of Informatics and Information Technologies Slovak University of Technology

  8. 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

  9. System overview • Contextual information • Entities (objects / “ideas”) • RFID tags • Messages (information) • Users • Visually impaired • Sighted Faculty of Informatics and Information Technologies Slovak University of Technology

  10. What is an RFID tag? Faculty of Informatics and Information Technologies Slovak University of Technology

  11. System operation

  12. 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

  13. Messages II • Contextual Information Description Language (CIDL) • Validity • Structured messages • Extensibility • Support for different languages • Links to multimedia/web content Faculty of Informatics and Information Technologies Slovak University of Technology

  14. 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

  15. Personalization and customization • Operation modes • Message category priorities • Too many tags nearby • Message filters • Repeating of irrelevant messages • Rogue messages – SPAM • Notifications • User interfaces Faculty of Informatics and Information Technologies Slovak University of Technology

  16. User interfaces Faculty of Informatics and Information Technologies Slovak University of Technology

  17. 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

  18. 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 Faculty of Informatics and Information Technologies Slovak University of Technology
