  3. 3. Topic<br />Learning 2.0<br />Web 2.0: Enables collaboration & interaction<br />Learning environment<br />Special needs<br />Aimed at mentally disabled<br />3<br />
  4. 4. Goals<br />Closing the digital divide<br />Improve competences<br />On the iPad<br />Fullscreen apps  Less distraction<br />Touchscreen<br />Easier for people who struggle with motoric skills<br />Attention span  because enjoy it more<br />Screen large enough (compared to iPod etc.)<br />4<br />
  5. 5. Research<br />5<br />
  6. 6. Research<br />Interactive: Interviews, contacting organizations, conference,…<br />6<br />
  7. 7. Research conclusions (1)<br />Digital Divide <br />Private social networks  Feel different<br />Literature focus<br />Technology Enhanced Learning (Tablets in classroom)<br />e-Accessibility for disabled (Guidelines)<br />Human Computer Interaction (Design + Evaluation)<br />Existing apps<br />Learning: LMS (Learning Management System)<br />Disabilities:<br />Communication solutions, AAC (Augmentive-Alternative Communication)<br />7<br />
  8. 8. Research conclusions (2)<br />Touchscreens  take away the thinking of bringing the mouse to a button to do an action<br />Extended CHI in a way that mimics human gestures<br />Need of adapted Text-to-Speech (less is more)<br />Tested existing Facebook apps<br />Tabs without pictograms  Guessing<br />Panicked when saw unknown friend request<br />8<br />
  9. 9. Idea<br />9<br />

Facebook app with data gathering<br />Accessibility to social technologies<br />Protected environment<br />Abuse<br />‘Bad’ social behavior<br />Customizable<br />3 major levels<br />T2S Data gathering<br />Clustering similar students<br />Focus learning on certain words<br />Avoid certain texts<br /> Support learning application<br />10<br />
  11. 11. Iterative process<br />11<br />
  12. 12. Iterative Process<br />Spiral methodology<br />Use results previous for following iteration<br />5 iterations<br />3 x Mentally disabled<br />1 x Guardians<br />1 x Both<br />Evaluation methodology based on:<br />Definition of goals<br />Guardians: Time + # taps<br />Mentally disabled: # taps<br />Scenarios<br />Mentally Disabled: Remembering how to execute a task (repeating scenarios)<br />Questions (Profiling + User satisfaction)<br />Think aloud tests<br />12<br />
  13. 13. Iteration I<br />Paper prototype<br />Two parts:<br />Guardians: Setting up application<br />Mentally disabled: Use of Facebook<br />Goals: Application usable by:<br />Persons who might not have experience with multitouch devices and/or social networks<br />Persons with a mental disability<br />13<br />
  14. 14. Iteration I - Paper prototype Overview<br />14<br />
  15. 15. Iteration I - Conclusions<br />Guardians:<br />5 persons<br />3 problems to be solved (Swiping, finding settings icon & Segmented control supertype)<br />Good suggestions<br />Mentally disabled<br />Disappointing<br />Hard for them<br />Not visual enough (lack of colors, handwriting,…)<br />Test with children for basic functionality<br />15<br />
  16. 16. Iteration II<br />Mockup since problems paper prototype<br />Focus on mentally disabled<br />iOS Interface Builder<br />Goal: Usable by mentallydisabled person? <br />16<br />
  17. 17. Iteration II - Conclusions<br />1 person with mental disability<br />Most scenarios successfully<br />Trouble with imagining something unreal<br />Expert feedback<br />Really positive reaction<br />Dilemma selection Consistency with existing<br />Buttons: Always speak out loud + navigate<br />17<br />
  18. 18. Iteration III<br />Implementation of application<br />Facebook API<br />Text-to-Speech SDK (Nuance Dragon Mobile)<br />OpenFlow API<br />Focus on mentally disabled<br />Goals:<br />Test new selection of words<br />Finding tabs with T2S support<br />18<br />
  19. 19. Iteration III - Conclusions<br />5 mentally disabled<br />Observations<br />T2S supported tabs success<br />Selection of words too difficult<br />Problem with pressing speaker icon<br /><ul><li> Tendency to keep pressing
  20. 20. Miss taps</li></ul>19<br />
  21. 21. Iteration IV<br />Focus on guardians<br />Further implementation application<br />Text-to-Speech data gathering<br />Exporting to CSV<br />Improvements to paper prototype<br />Goals: <br />Testing new functions<br />Testing problems paper prototype solved<br />20<br />
  22. 22. Iteration IV - Conclusions<br />5 persons<br />Observations<br />All scenarios completed successfully<br /> Guardians & teachers are able to use the application<br />21<br />
  23. 23. Iteration V<br />Focus on mentally disabled<br />Improvements<br />Hide speaker icon + made bigger<br />Ideal selection of words method in existing application  Contacted company (software engineering team)<br />Goals:<br />Testing improvements<br />22<br />
  24. 24. Iteration V - Conclusions<br />9 mentally disabled<br />Used existing application to test selection<br />Observations<br />New selection method big improvement<br />Hiding speaker icon also success<br />23<br />
  25. 25. Conclusion<br />24<br />
  26. 26. Results<br />Learning power in its Text-to-Speech data gathering<br />Successful to close the digital divide<br />Able to go on Facebook on their own without guardian having to worry<br />Many positive reactions by teachers, parents AND mentally disabled persons<br />“I’m going to steal iPad of my sister to get this app”<br /> Gave enormous satisfaction<br />25<br />
  27. 27. Major Difficulties<br />Mentally disabled<br />Imagining something unreal <br />Could give wrong impression that application is not good<br />Implementation<br />Getting used to working on mobile device Memory management<br />Matching Facebook responses  Type unclear<br />Selection not working as planned UIWebView different when not a lot content<br />26<br />
  28. 28. Possible Future Work<br />Auto-translation functionality<br />Non-mentally disabled friends<br />Extend application<br />Used by elderly people<br />In the car<br />27<br />
  29. 29. Demo<br />28<br />
