  2. What is this talk (and thesis) about? Understanding and supporting the usage and adoption of assistive technologies by people with reading disabilities K. Deibel, Assistive Technologies and Reading Disabilities

  3. Why does it matter? • Reading is a critical skill in an information society • 7-15% of the population have reading disabilities (e.g., dyslexia) • Computer-based assistive tools can provide successful accommodations • A tool is only helpful when it is used Refs: Sands & Buchholz,1997 K. Deibel, Assistive Technologies and Reading Disabilities

  4. Abandonment of Assistive Technology • 35% of all assistive technologies purchased are abandoned • Waste of resources, time, and funds for users and disability services • Bad experiences lead to disillusionment about assistive technologies Refs: Phillips & Zhao, 1993; Martin & McCormack, 1999; Rimer-Reiss & Wacker, 2000 K. Deibel, Assistive Technologies and Reading Disabilities

  5. Research Questions • What technologies are helpful to people with reading disabilities? • What technologies are used by people with reading disabilities? • What technologies get abandoned by people with reading disabilities? Why? • What helps make a technology adoptable? • How can we use this knowledge to make better technologies? K. Deibel, Assistive Technologies and Reading Disabilities

  6. Computer science Reading on computers Digital literacies Human-computer interaction Education Technology adoption Reading sciences Assistive technology A Multidisciplinary Effort Insights from many research areas: K. Deibel, Assistive Technologies and Reading Disabilities

  9. What is a reading disability? • Profound difficulty with learning to read and the act of reading • Phonological processing deficit • Letter and word misidentification • Impacts reading comprehension • Visual stress • Letters and words move and blur together • Difficulty sustaining reading Refs: Sands & Buchholz,1997; Dickinson et al., 2002 K. Deibel, Assistive Technologies and Reading Disabilities

  10. Social aspects of reading disabilities • Poor reading is socially associated with poor intelligence • Individuals with reading disabilities experience: • Self-doubt, low confidence, and feelings of isolation • Teasing from peers • Expectations from others to fail • Viewed as lazy or attempting to fraud the system Refs: McDermott, 1993; Edwards, 1994; Williams & Ceci, 1999; Zirkel, 2000; Cory, 2005; K. Deibel, Assistive Technologies and Reading Disabilities

  11. Invisible nature of reading disability • Disability not visually apparent to others • Allows individual to hide as “normal” • Avoid disability stigma • Limit knowledge to trusted others • Delay asking for help Refs: McDermott, 1993; Edwards, 1994; Cory, 2005; K. Deibel, Assistive Technologies and Reading Disabilities

  12. Outline • Motivation and Introduction • Short Background on Reading Disabilities • Current Research and Its Gaps • Assistive Technologies for Reading • Assistive Technology Adoption Studies • Sociocultural Factors: Understanding the Gaps • Summary K.

  24. Summary of adoption studies • Only specific technology studies for users with reading disabilities • No studies of general technology usage among people with reading disabilities • Multiple disability studies do not report findings by disability type • Text-to-speech has a high abandonment rate (small n studies) K. Deibel, Assistive Technologies and Reading Disabilities

  25. Outline • Motivation and Introduction • Short Background on Reading Disabilities • Current Research and Its Gaps • Assistive Technologies for Reading • Assistive Technology Adoption Studies • Sociocultural Factors: Understanding the Gaps • Summary K. Deibel, Assistive Technologies and Reading Disabilities

  26. The Gaps • Assistive technology development mainly restricted to text-to-speech despite frequent abandonment • Adoption studies often cover other disabilities • Reading disability adoption studies limited to specific technologies K. Deibel, Assistive Technologies and Reading Disabilities

  27. Sociocultural factors • Various social and cultural factors affect research and development of assistive technologies for reading disabilities • Factors include: • Nature of reading disabilities • Social views on disabilities • Educational policies and philosophies • Available technologies • Technology practices K. Deibel, Assistive Technologies and Reading Disabilities

  28. Text-to-Speech and Display Technologies • Text-to-speech developed in 1990s • Most work conducted on desktop machines with CRT displays • Displays known to be non-conducive to vision-only reading • Developers made best use of technologies available at the time • Insight: Explore potentials of portable computers (PDAs, tablets, etc.) that are better designed to support reading Refs: Farmer, 1992; Gujar et al., 1998; Waycott & Kukulska-Hulme, 2003 K. Deibel, Assistive Technologies and Reading Disabilities

  29. Assistive Technologies and Medicine • Early AT adoption studies conducted by rehabilitation doctors • Focused on disabilities they treated • Reading disabilities are not “treated” medically but through education • Insight: Consider the different policies, laws, funding, philosophies, etc. between medical and educational treatment of disabilities Refs: Phillips & Zhao, 1993; Clough & Corbett, 2000 K. Deibel, Assistive Technologies and Reading Disabilities

  30. Education and the Medical Model Typical Education Research Approach: • Phonological processing deficit • Listening to text read aloud bypasses deficit • Text-to-speech technology • Use text-to-speech for remediation Medical model of disability: A disability is a flaw or defect that needs fixing or bypassing Refs: Sands & Buchholz, 1997; Clough & Corbett, 2000 K. Deibel, Assistive Technologies and Reading Disabilities

  31. Educational Model of Disability • Person has education disability about X • Sub-skill Y is identified as lacking • If we remediate or bypass Y, X will improve • Efforts that ignore Y are not pursued • Insight: Consider interventions not involving phonological processing deficit K. Deibel, Assistive Technologies and Reading Disabilities

  32. Repercussions of Educational Model • Focus on early reading • Emphasis on early interventions, K-5 • Ignores transition from “learning to read” to “reading to learn” • Insight: Lack of support for more advanced reading skills and tasks Refs: Wineburg, 1991; Cunningham & Stanovich, 1997; Peskin, 1998, Peer & Reid, 2001 K. Deibel, Assistive Technologies and Reading Disabilities

  33. Repercussions of Educational Model • Focus on reading at school • Reading takes place outside of schools • AT often deployed only in the school labs • Insight: Current assistive devices not designed for use in multiple locales Refs: Laga et al., 2006 K. Deibel, Assistive Technologies and Reading Disabilities

  34. Invisible nature of reading disability • Disability not visually apparent to others • Allows individual to hide as “normal” • Avoid disability stigma • Limit knowledge to trusted others • Delay asking for help Refs: McDermott, 1993; Edwards, 1994; Cory, 2005; K. Deibel, Assistive Technologies and Reading Disabilities

  35. Invisibility and Technology Usage Would text-to-speech be used in a…. • …lecture hall? • …library? • …study group? • …in a dorm room with roommate? • …in a dorm room alone? • Insight: Need awareness of different contexts and how they affect usage K. Deibel, Assistive Technologies and Reading Disabilities

  36. Invisibility and Adoption Theories • Diffusion of Innovations is the seminal text and theory on technology adoption • Key aspect is communication of ideas • Social network of users and adopters Refs: Rogers, 2003 K. Deibel, Assistive Technologies and Reading Disabilities

  37. Invisibility and Lack of Diffusion • People with reading disabilities tend to tactically hide disability from others • Stealth usage of technology slows diffusion • Social network of users is sparse • Disclosure of disability also uncertain • Insight: Standard theory of technology adoption is not readily applicable Refs: Rogers, 2003 K. Deibel, Assistive Technologies and Reading Disabilities

  38. Outline • Motivation and Introduction • Short Background on Reading Disabilities • Current Research and Its Gaps • Assistive Technologies for Reading • Assistive Technology Adoption Studies • Sociocultural Factors: Understanding the Gaps • Summary K. Deibel, Assistive Technologies and Reading Disabilities

  39. Summary • Research literature on assistive technologies for reading disabilities is limited in scope • Various social and cultural factors have influenced previous and current research • Understanding these factors allows for better future research K. Deibel, Assistive Technologies and Reading Disabilities

  40. Ongoing research • Case studies of people with reading disabilities emphasizing: • Usage of technologies to support reading • The types and contexts of their reading activities • Identifying additional social and cultural factors • Development of new assistive technologies: • Supports invisible nature of reading disabilities • Adjustable to multiple usage contexts K. Deibel, Assistive Technologies and Reading Disabilities
