University of Wolverhampton's LUCID activities

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