4. Memory Refresh: Subject
Learning 2.0
Web 2.0: Enables collaboration & interaction
Learning environment
Special needs
Aimed at mental disability
On the iPad

5. Memory Refresh: Research conclusions
Digital divide
Private network makes them feel different
Need of adapted Text-to-speech (too complicated now)
Can do more than most think!
Touchscreens take away the thinking of bringing the mouse to a button to do an action
5
6. Memory Refresh: Application Idea
Part I: Facebook application
Accessibility to social technologies
Text-to-Speech + gathering data
Pictograms
Protect from abuse, bad social behavior,
Part II: Visualization application
2nd priority: If goals part I achieved!
Clustering similar students
Focus on certain words
Avoiding certain texts
COMBINED: A support learning application without the users even knowing it!

7. New Work
7
8. Varia
Contacted organizations
Facebook -> Couldnt answer research related questions
Amichai -> Not working on something like it
Tested existing Facebook applications
Tabs without pictograms -> More guessing
Could not understand statuses
Panicked when saw unknown friend request
Paper
Brainstorm Visualization application
Better to drop visualization application
Can import CSV file in existing apps (ex. Excel)
8
9. Iteration II
Mockup since problems paper prototype
iOS Interface Builder
Biggest resemblance
Avoids double work
Needs controller view classes
Goal: Testing usability
Think aloud test

10. Iteration II - Evaluation
Scenarios for person with mental disability:
Who was the last one that posted something on your wall?
Let something to be read out loud (for example a wallpost).
Update your status (again with a popup to see their reaction).
Whose birthday is it today?
When is event X?
Can you read out loud what person Y said to person Z?
Start a new Facebook chat.
Can you check who your friends are?
Of which groups are you a member?
10
11. Iteration II - Evaluation
Some questions afterwards:
Have you ever used Facebook?
Do you have a Facebook account yourself? If not, interested in one?
Any experience with a touchscreen? Could be a smartphone,
Any with the iPad?
11
12. Iteration II - Evaluation
1 person with mental disability
Most scenarios successfully
Scenario 2 other way than intended
Problem with scenario 4
Trouble with imagining something unreal
Expert feedback
Really positive reaction
Dilemma selection -> Consistency with existing
Buttons: Always speak out loud + navigate
Other suggestions: Hierarchy for status updates, changeable font

13. Iteration II - Demo
13
14. Iteration III
Implementation of application
Facebook SDK
Text-to-Speech SDK (Nuance Dragon Mobile)
Progress:
Facebook connection: OK
Text-to-Speech: OK
Full functionality Facebook: +/-
Selection gesture: NOT OK
Sclera pictograms to update status: +/-
14
15. Iteration III - Evaluation
First week after Easter holidays
At least 5 persons with mental disability
Goal: Usability & Usefulness (will they reuse it?)
Same scenarios + questions Iteration II
15
16. Iteration III - Demo
16
17. Problems
17
18. Problems
Selection gesture adaption in iOS
Losing a lot of time with it -> Postponed evaluation moment
Memory management iPad
Coverflowcrashes
If friends > 200

20. Future Iterations
20
21. Iteration IV
Implementation
Adaptions after Iteration III
Add settings for guardians
Evaluation
Test settings if usable by persons without iPad and/or social network experience
Focus on:
Effectiveness: Success rates
Efficiency: Time to complete task
User satisfaction: Opinion about application
21
22. Iteration V
Implementation
Adaptions iteration IV
Translation functionality
Google Translate for statuses
Auto language detection
Already have trouble with 1 language
Friends without disability
Evaluate adaptions
10 persons with mental disability
Split up in 2 groups
1 my app1 existing text-to-speech app + FB website
Time difference & success rates
Questions checking feeling about app
If allowed enough time
Switch groups: Avoid biased result
Every person different level & experiences
