      • “ 85% of people who did X then did Y …”
      • Guiding v. Leading?
      • Empowering v. controlling
  • 8.
    • REGIONAL CONTEXT
    • Many cities developing large scale WLAN
    • Many intuitive benefits - workers, visitors, citizens, etc
    • Revenue generation mechanisms less obvious …
    • Context Awareness offers new opportunities for personalised revenue generating services

      • Business Users and Business Applications
  • 9.
    • AWM Science City
    • A real force to use science and technology to improve the prosperity & quality of life in Birmingham, WM & the UK
    • Overall vision:
      • a world class research base,
      • capacity to translate knowledge into real products and Services,
      • the people, skills and infrastructure to do this,
      • engagement with science in schools and across the population
      • demonstrator and flagship projects
    • Five areas of scientific and technological strength highlighted:
      • Digital Media / Energy / Materials
      • Medical Technology & Healthcare / Transport
  • 10.
    • LUCID Project
    • Exploring potential applications of Location, User and Context Aware software applications and services
    • Supporting a wide range of mobile devices and connectivity types and content delivery paradigms
    • Leverage BCC investment in the Wireless Square Mile & Free Information Zone (FIZ) to increase uptake
    • Developing of a number of “proof of concept solutions” for technical and user evaluation
    • Primary focus of “what does it do for the users” not “look how clever this thing is” - embedded user feedback and evaluation
  • 11.
    • CONTENT QUESTIONS
    • How can we “mark-up” rich-media content with the locations to which it is relevant?
    • What about other “user preference” mark-up?
    • How can we “tag” a location with multiple media artifacts for access by all applications?
    • How can the public tag physical (and virtual) locations with their own media artifacts – “cyber-graffiti” ?
    • By what mechanisms could we “deliver” tagged media to mobile users in a seamless way?
    • Content delivered as real-time stream? cache and carry? pre-load? content oasis?
  • 12.
    • LOCATION QUESTIONS
    • How could we integrate absolute position data from GPS with relative locations from other local “beacons”?
    • How do we seamlessly move from GPS outdoors to indoor location systems whilst maintaining our position?
    • How could we use passive or active RFID tags as external location identifiers?
    • How could we “register” media tag locations so that GPS data would “know” that they were in the vicinity?
    • How could we fuse other data, e.g. direction, acceleration, images, etc to assist with location / selection / identification / delivery of media contents?
  • 13.
    • CLOSED SYSTEM
    • A museum has external and internal exhibit space and has a created an outside “knowledge trail” using GPS assisted PDAs.
    • Museum collections has been digitised and is accessible via the museum web-site
    • How can the museum create a personalised and interactive “tour” responsive to individual interests / needs that involves external and internal exhibits?
    • ISSUES: identify current user location and tagged media content and retrieve from museum server
    • Where is user? Which gallery? Near which exhibit? What do they want / need? Where have they been before?
  • 14.
    • OPEN SYSTEM
    • A city has created a walking tour of the canal network with media tagged to key points of interest
      • GPS equipped PDA with media pre-loaded on SD card.
      • In some 10 m radius zones there may be > 5 POI with tagged content ,
    • At the Visitors’ Centre there are three open WLAN access points giving access to web-based information
    • An architecture trail has also been created which crosses the canal tour and has common POI inc. VC
    • Potential visitors would like to see some of the POI before coming to the city – “virtual tour”
    • How can the “tours” share media content?
    • How can www / WLAN be integrated into the two tours?
  • 15.
    • ENABLING TECHNOLOGIES
    • Identification & Data Carriers
      • 1D barcodes and 2D codes
      • Passive RFID
      • Active RFID
      • Smartcards
      • Biometrics
  • 16.
    • ENABLING TECHNOLOGIES
    • 1D barcodes and 2D codes
      • Optical read-only data-carriers
      • 2D codes up to 4000+ characters
      • QR and DataMatrix often used with phones
      • Image capture / decode / URL / connect
      • Can hold identifier, link or data (or all)
      • 2D have robust ECC
  • 17.  
  • 18. Generating 2D Codes …
    • Many software tools and components available
    • Free tools and on-line resources too:
      • E.G. http://mobilecodes.nokia.com
  • 19. 2D Code Reader Software
    • Phones are starting to have this built-in
    • Consumer applications developing fast
    • URL in 2D code then redirect browser
    • QR code & Datamatrix are supported
    • Many free downloads of 2D code readers
      • I-nigma reader: http://www.i-nigma.mobi
      • NeoReader: http://get.neoreader.com
      • UpCode reader: http://www.upcode.fi Semacode reader: http://semacode.org/ota QuickMark reader: www.quickmark.com.tw
  • 20. Smartcards
    • Data is stored electronically in a small semiconductor memory device, normally in the form of a card
    • Contactless cards can be read / written by short-range radio (5-7 cm) e.g. Oyster card, Barclaycard “waterslide”
      • 13.56 MHz air-interface ISO-14443 for smartcards
      • ISO-15693 for High-Frequency RFID
    • Card memory divided into different blocks with security / encryption and other functions e.g. purse
    • Applications can read from, and if necessary write to the smartcard e.g. to decrement stored value, etc
    • Some “very-smart” cards run Java applications
  • 21. Convergence …
    • Smartcards are typically carried by the user and hold key personal data, stored value, etc
    • 2D codes can be placed in different physical locations to “mark-up” space or identify things and hold thicker data
    • Barrier to consumer uses of smartcards and 2D codes has been the availability of readers / writers
    • BUT: phones have a camera and Near-Field Communications is coming …
  • 22. Near-Field Communications
    • Short-range (10 cm) HF (wireless communication
    • Data exchange between handset devices, smartcards, RFID tags, etc
    • Extension of the ISO 14443 proximity-card standard and supports ISO-15693 HF RFID standards.
    • Smartcard interface and a reader in a single device
    • Compatible with existing contactless infrastructure
    • Aimed primarily at mobile phones & embedded stuff
  • 23.
    • ENABLING TECHNOLOGIES
    • RADIO-FREQUENCY IDENTIFICATION
      • Data stored in a small semiconductor device
      • Data is read from (and written to) the RFID device using various forms of RF communications
      • Passive devices powered by the interrogator and have no internal battery, active have a battery
      • Direct line-of-sight is not required to read /write data
      • Can simultaneously interrogate a number of tags
  • 24. 1. Tag enters RF field 2. RF field interrogates / powers tag 3. Tag transmits ID (plus data) 4. Reader sends data to computer 5. Computer determines action 6. Computer instructs reader 7. Reader transmits new data to tag How Does Passive RFID Work? Antenna Tag Computer
  • 25. The RFID Spectrum KHz MHz GHz Audio 20Hz – 20 KHz AM Radio LW 150-270 KHz MW 535-1600 KHz FM Radio / TV FM 87.5 – 108 MHz UHF 470 – 854 MHz Cell Phones GSM 1800 MHz USA 1900 MHz Microwave 2.4 GHz 125–134 KHz LF Tags 13.56 MHz HF Tags 433, 860-930 MHz UHF Tags 2.45, 5.8 GHz Microwave Tags
  • 26.
    • ENABLING TECHNOLOGIES
    • Active RFID
      • RFID tag is a small RF transmitter (433 MHz)
      • Transmits a “pulse” (ID plus other data)
      • Reader only has to receive transmission not power the tag – unlike passive tags
      • Ranges up to 200 metres or more
      • If battery dies, tag becomes invisible
  • 27. A Data Perspective
    • Key thinking point when building apps:
      • Where is the data I need?
      • How can I connect to the data?
      • What happens if I can’t connect to it?
    • Data-carriers carry data that is either:
      • a reference allowing a (remote) look-up of item data :
      • the data, or subset of operational data
  • 28. Back to LUCID …
    • Lots of technology building blocks
    • Many exciting potential ideas for combining these for service delivery but:
      • What are the “killer apps”?
      • What are the user benefits?
      • What are the technology barriers?
      • What are the user acceptance barriers?
    • Need to find out, hence the LUCID project!
