3. Topic Learning 2.0 Web 2.0: Enables collaboration & interaction Learning environment Special needs Aimed at mentally disabled 3
4. Goals Closing the digital divide Improve competences On the iPad Fullscreen apps Less distraction Touchscreen Easier for people who struggle with motoric skills Attention span because enjoy it more Screen large enough (compared to iPod etc.) 4
7. Research conclusions (1) Digital Divide Private social networks Feel different Literature focus Technology Enhanced Learning (Tablets in classroom) e-Accessibility for disabled (Guidelines) Human Computer Interaction (Design + Evaluation) Existing apps Learning: LMS (Learning Management System) Disabilities: Communication solutions, AAC (Augmentive-Alternative Communication) 7
8. Research conclusions (2) Touchscreens take away the thinking of bringing the mouse to a button to do an action Extended CHI in a way that mimics human gestures Need of adapted Text-to-Speech (less is more) Tested existing Facebook apps Tabs without pictograms Guessing Panicked when saw unknown friend request 8
10. Facebook app with data gathering Accessibility to social technologies Protected environment Abuse ‘Bad’ social behavior Customizable 3 major levels T2S Data gathering Clustering similar students Focus learning on certain words Avoid certain texts Support learning application 10
12. Iterative Process Spiral methodology Use results previous for following iteration 5 iterations 3 x Mentally disabled 1 x Guardians 1 x Both Evaluation methodology based on: Definition of goals Guardians: Time + # taps Mentally disabled: # taps Scenarios Mentally Disabled: Remembering how to execute a task (repeating scenarios) Questions (Profiling + User satisfaction) Think aloud tests 12
13. Iteration I Paper prototype Two parts: Guardians: Setting up application Mentally disabled: Use of Facebook Goals: Application usable by: Persons who might not have experience with multitouch devices and/or social networks Persons with a mental disability 13
15. Iteration I - Conclusions Guardians: 5 persons 3 problems to be solved (Swiping, finding settings icon & Segmented control supertype) Good suggestions Mentally disabled Disappointing Hard for them Not visual enough (lack of colors, handwriting,…) Test with children for basic functionality 15
16. Iteration II Mockup since problems paper prototype Focus on mentally disabled iOS Interface Builder Goal: Usable by mentallydisabled person? 16
17. Iteration II - Conclusions 1 person with mental disability Most scenarios successfully Trouble with imagining something unreal Expert feedback Really positive reaction Dilemma selection Consistency with existing Buttons: Always speak out loud + navigate 17
18. Iteration III Implementation of application Facebook API Text-to-Speech SDK (Nuance Dragon Mobile) OpenFlow API Focus on mentally disabled Goals: Test new selection of words Finding tabs with T2S support 18
21. Iteration IV Focus on guardians Further implementation application Text-to-Speech data gathering Exporting to CSV Improvements to paper prototype Goals: Testing new functions Testing problems paper prototype solved 20
22. Iteration IV - Conclusions 5 persons Observations All scenarios completed successfully Guardians & teachers are able to use the application 21
23. Iteration V Focus on mentally disabled Improvements Hide speaker icon + made bigger Ideal selection of words method in existing application Contacted company (software engineering team) Goals: Testing improvements 22
24. Iteration V - Conclusions 9 mentally disabled Used existing application to test selection Observations New selection method big improvement Hiding speaker icon also success 23
26. Results Learning power in its Text-to-Speech data gathering Successful to close the digital divide Able to go on Facebook on their own without guardian having to worry Many positive reactions by teachers, parents AND mentally disabled persons “I’m going to steal iPad of my sister to get this app” Gave enormous satisfaction 25
27. Major Difficulties Mentally disabled Imagining something unreal Could give wrong impression that application is not good Implementation Getting used to working on mobile device Memory management Matching Facebook responses Type unclear Selection not working as planned UIWebView different when not a lot content 26
28. Possible Future Work Auto-translation functionality Non-mentally disabled friends Extend application Used by elderly people In the car 27
Integration Web 2.0 tools which enables collaboration and interaction in a learning environment
For the research the biggest focus was, as you can see in the chart, on literature but we also used an interactive approach by doing interviews, contacting organizations and going to the Inlcuse conference in Leuven.
Existing app doordatnietklaarvoorevaluatie dag
We can conclude that the learning power of this application is in it T2S data gathering
