  1. The Aphasia Project Designing Technology For and With People who have Aphasia Maria Klawe, Sonya Nikolova, Jordan Boyd-Graber Princeton University Marilyn Tremaine, Rutgers University Joanna McGrenere, Peter Graf, Barbara Purves, Karyn Moffatt, Meghan Allen University of British Columbia

  2. Outline • What is Aphasia? • Problems with existing solutions • The evolution of ESI planner • Broader impacts

  3. What is Aphasia? Aphasia is a loss of words – not intelligence lhd have meelk • Acquired language disorder • Caused by brain damage (e.g. stroke, trauma, etc.) • Impairment of communication abilities • Relative sparing of other cognitive abilities

  4. Impact of Aphasia • More common than Parkinson’s disease • Withdrawal from society

  5. Problems with existing solutions • Limited to communication; lack of higher level applications • Communication too slow for most aphasics • Stigma of relying on laptops in public • Poor user-interface of handhelds • Buttons too small • Confusing navigation • Poor organization of multi-media data

  6. The Aphasia Project • Goal: understand how individuals with aphasia communicate and seek opportunities where technology can better support individuals in their daily life • Interdisciplinary project: computer science, psychology, speech language pathology • Multi-site: UBC, Princeton, aphasia centers,

  7. Types of Subprojects I: Participatory design of application prototypes • Daily planner • Handheld • Combined handheld and laptop system • Recipe book (laptop or tablet) • File system (handheld) II: Evaluation of commercial PDAs • Long term use by Skip • Short term use of camera function

  8. Special challenges with research involving aphasics • Access to participants • Communication with participants • Right hemiparesis • Lack of experience with computers, PDA • Uncertain future of PDAs

  9. I: Participatory Design of High-Level Application Prototypes Anita Borg, 1949 - 2003 • daily planner • interactive cookbook Karyn Moffatt

  10. ESI Planner 1 The Enhanced with Sound and Images Planner • PDA application (iPaq from HP) • A computerized daily planner designed for people with aphasia • Uses images, sound, and text to represent people and places in appointments

  11. I: Images, Sound, Text… • Say you have an appointment with Queen Elizabeth, at the Eiffel Tower on November 6, 2003 from 8:00am to 10:00am • ESI Planner would display it like this:

  12. I: Participatory Design • Four phases

  13. I: Participatory Design • Four phases • Idea brainstorming • Interviews • Identified needs: • Daily planner • Recipe book ? ? ?

  14. June: 9/6/03 6 7:00 am - 9:30 am 7 8 Marilyn Monroe Eiffel Tower 9 10 10 11 Starts 11 : 15 20 12 1 Ends 1: 00 05 2 3 4 5 6 7 8 I: Participatory Design • Four phases • Idea brainstorming • Paper low-fi prototypes 2 - Using computer tools 1 - Drawn by hand

  15. I: Participatory Design • Four phases • Idea brainstorming • Paper low-fi prototypes • Medium-fi prototypes

  16. I: Participatory Design • Four phases • Idea brainstorming • Paper low-fi prototypes • Medium-fi prototypes • High-fi prototypes and formal evaluation in lab

  17. I: High-fi Prototypes ESI Planner NESI Planner

  18. I: Formal Evaluation • 8 participants • Session 1: • 30 minutes with each Planner (ESI and NESI) • 10 tasks (retrieval, creation, modification) • # of tasks completed • # of tasks completed correctly • Session 2: Western Aphasia Battery

  19. I: Results Preference: 5 ESI, 3 NESI. Significantly more tasks completed correctly with ESI Planner.

  20. Limitations of ESI Planner 1 • Need for field study • Interface for input and modification of appointments • Lack of stable memory on iPAQ after power loss • Lack of library of icons and sounds

  21. ESI Planner 2 • Input on laptop • Lingraphica library of icons and sounds • Stable memory • Built-in camera in iPAQ • Participatory design with speech language pathologists (SLPs) • Four week field study

  22. Lingraphica • Current Lingraphica system • Laptop-based (easier interface) • Used at home for practice • Issues • Expensive, restricted to AAC insurance diagnosis • Stigma

  23. A Lingraphica phrase

  24. Initial goal for prototype • Download appointments and phrases from Lingraphica to ESI planner on handheld • Anticipated uses • Visits to doctors, etc. • Shopping • Medication

  25. ESI Planner 2 home

  26. appointments

  27. phrase

  28. The need for LgLite • Lingraphica (Lg) too complex • Inability to add photos in Lg • No Windows version of Lg

  29. LgLite interface

  30. LgLite interface

  31. The Pilot Field Study • Seven aphasics at Adler Aphasia Center • Four weeks, one videotaped meeting with each participant per week • Log of interactions with iPAQ and computer

  32. Outcomes • Little use of appointments • Input only possible at Adler Center • Desire for input on iPAQ • Extensive use of camera • Desire for better photo management on iPAQ • Problems with sound playback • Range of text and speech abilities • Enthusiasm for continued use of iPAQs

  33. Next steps • Add input on iPAQ • Improve photo management on iPAQ • Improve sound playback • Improve LgLite interface • Another field study at Adler

  34. Broader impact • Dual usefulness between aphasics and elderly (poor vision, memory loss, Alzheimers, etc.) • Other visual language applications
