University of Wolverhampton's LUCID activities University of Wolverhampton's LUCID activities Presentation Transcript

  • Chris Dennett School of Computing and IT University of Wolverhampton [email_address]
  • The Wolverhampton Perspective
    • Our position at the start of the project
    • Our philosophy
    • Our considerations and aims
    • Our solutions
    • The issues we faced
    • Our position at the end of the project
  • Our Position at the Start
    • No fancy Wi-Fi enabled square mile to play with!
      • Therefore, no simple access to collaborative partners
    • Research experience in wireless communications
    • Research experience in development of multimedia for mobile devices
  • Our Philosophy
    • Mobile technology should, by now, be more pervasive, forming an integral part of our daily lives
    • The public has a good working knowledge of how their own phone works
    • They will learn new skills if they perceive a use for them
    • Systems that communicate with these devices need to be cheap, sustainable, low maintenance and easy to use
  • Our Considerations
    • For the project to be successful, we needed
      • To use devices that don't require hours of training to understand – Both on the transmitting end and on the receiving end
      • A solution that is sustainable
      • A solution that is as widely available or accessible as possible
  • Our Solutions – Handheld Devices
    • Make use of existing, ubiquitous technology
    • Mobile phones
      • Everyone has one
      • They know the issues with their own device
      • Sustainable – No need to supply/lend devices to public. No requirement to service them
  • Our Solutions – Handheld Devices
    • Mobile phones have multiple wireless technologies with which to engage the public
      • SMS... Cheap but dull
      • MMS... Multimedia but expensive
      • 3G internet... Expensive and hard to tie in contextualised information
      • Bluetooth... Cheap (ie. Free), built in physical context, widely available, but low bandwidth
      • Wi-Fi... high bandwidth, but hard to tie in contextualised information
  • Our Solutions – Handheld Devices
    • Mobile phones have multiple on board technologies that we can make use of
      • Video and Audio capabilities – great interaction with users but can mean large files and therefore long transmission times
      • Graphics, Animations – Not quite so pretty, but small files
      • GPS – Increasingly available on common devices, can be used to initiate stuff on phones
  • Our Solutions - Transmitters
    • Base stations
      • Detect Bluetooth enabled phones
      • Interrogate database to see what is available for transmission based on time, date, type of phone
      • Work out whether they've already been sent stuff
      • If not, then send stuff
      • If they don't accept within 3 attempts, don't send any more
  • Our Solutions - Transmitters
    • Pico-ITX
    • Embedded 1GHz processor
    • Custom Linux build
    • Bluetooth Dongle
    • Runs our database, Bluetooth management software and message construction software
  • Our Solutions – What Got Sent
    • Different phones support different file formats
    • With the intention of hitting the widest possible number of phones, we go back in time to the animated .GIF
      • Not the most high tech format, but surprisingly effective
      • Also keeps file size low, important for fast transmission
  • Our Solutions – What Got Sent
    • For newer, high end phones
    • A one-shot application that runs our tours
      • Large file size, requires installation
      • After installation, much smaller packages containing whole tours (images, GPS locations, voice, text) can be transmitted
      • The installed application interprets the contents of these packages
      • Upon arrival at a GPS location, multimedia pops up on phone
  • Our Solutions – What Got Sent
    • GPS tour application still buggy
    • We resorted to separate tour files
      • Each tour is a stand alone application
      • Time consuming to create, but robust
  • Issues Encountered
    • Issue #1
    • Companies that we collaborate with only get to trial the kit. What do they do afterwards?
    • We put the whole software system on a flash disk. Added a Bluetooth dongle.
    • Find an old machine, plug them in and turn it on... Hey presto! Instant Transmitter
  • Issues Encountered
    • Issue #2
    • Blackberries and iPhones
    • The number of times someone has asked 'Why doesn't it work with my XXXX?'*
    • RIM and Apple devices only support Bluetooth headsets.
      • In Apples case, we think this is something to do with file sharing issues
    *insert Blackberry or iPhone here
  • Our Position at the End
    • Some great sustainable tools that allow free transmission to user owned devices
    • A developing GPS triggered tour system that will take time and previous tours into account, extending the concept of context aware tours beyond just the present and physical
    • A much greater knowledge of what works on mobiles
  • Our Position at the End
    • A bunch of willing test subjects... errrr... I mean collaborators for future work into context aware learning
    • Especially, but not only
      • Jungleland, Park Hall Farm, Wonderland,
      • Hoo Farm, Rays Farm, Wroxeter Roman Vineyard,
      • Hundred House Hotel, Park Inn, Buckatree,
      • Shrewsbury Music Hall, Ironbridge Gorge Museum,
      • Weston Park, Telford Whitehouse, Southwater event group
      • Jays Cafe
