  • 1. IBM Research in Brazil© 2013 IBM CorporationFirefixia: An Acessibility Web BrowserCustomization Toolbar for People with DyslexiaSantana, V. F.; Oliveira, R.; Almeida, L. D. A.; Ito, M.IBM Research BrazilFederal University of ABCFederal University of Technology - Paraná
  • 2. IBM Research in Brazil© 2013 IBM CorporationIntroduction “Web accessibility means that people with disabilities can perceive, understand, navigate,and interact with the Web, and that they can contribute to the Web” (Web AccessibilityInitiative) Approximately 15% of the worlds population have some form of disability (World HealthOrganization) 15-20% of the population have some of the symptoms of dyslexia (IDA):– slow or inaccurate reading;– poor spelling;– poor writing;– mixing up similar words. At least 0.28% of the Web pages contain misspellings performed by people with dyslexia(Baeza-Yates and Rello) Web Content Accessibility Guidelines (WCAG) 2.0 mentions dyslexia in only one successcriterion (i.e., 3.1.5 Reading Level)– This might impact the way that WCAG readers consider dyslexia

  • 17. IBM Research in Brazil© 2013 IBM CorporationExperiment Design Evaluation of the Firefixia– Adults diagnosed from Brazilian Association of Dyslexia– 2 or 3 test facilitators– Pre-test questionnaire• Age• Education• Work• Use of internet• Time since the dyslexia was diagnosed• The use of any assistive technology– List of 4 tasks to be performed by the participants in the Brazilian Federal Revenuepage– Post-test questionnaire• User’s opinion regarding the studied website• Analyze Firefixia’s characteristics.
  • 18. IBM Research in Brazil© 2013 IBM CorporationResults 13 candidates (18 to 45 years old) – 6 agreed to participate by phone – 4 attended the test Characteristics of the 4 people that attended the test:– Male– Diagnose: less than 1 year to more than 10 years– Did not do any kind of treatmentParticipant Age Scholar Level DifficultiesA 18 High School Exchange word in reading when tiredExchanging letters “p” and “b”Difficulty in writingB 24 Graduate Difficult to interpret numbersC 62 Graduate Hard to read after the 3rdphraseD 39 Undergraduate Difficulty in reading, interpreting numbers, readcontinuously and to know what is the line beingread
  • 19. IBM Research in Brazil© 2013 IBM CorporationResults Participants C and D found difficult to use the evaluated website Participants A and B did not point any critical issue, except by participant A that indicatedthat the text legibility was not bad Participant A suggested the inclusion of a feature to indicate the line being read Participant C said that missed a text search and orthographic correction Participant D was a Chrome user and asked us to develop Firefixia for his favorite Webbrowser Participants A and B mentioned that they want a copy of the toolbar to use it at home– In these cases, we informed that this is an ongoing study and that, as soon as wedeploy Firefixia, we would get in touch with all of them Customization features that all participants mentioned as useful (i.e., the intersection of allopinions) are the following: text size, text alignment, and link color. In relation to the opinions regarding the Firefixa, the answers ranged from good to reallygood
  • 20. IBM Research in Brazil© 2013 IBM CorporationConclusion This work presented a qualitative study on how an end-user customization toolbar for aWeb browser can help people with dyslexia. The toolbar reached its goals by pointing an interesting direction on allowing end-usercustomization of websites. Text size, text alignment, and color represent interesting customizable features websitesshould offer As stated in the accessibility literature, the development of technologies for improvingaccessibility helps people with and without disabilities.
  • 21. IBM Research in Brazil© 2013 IBM CorporationFuture Works Qualitative and quantitative studies about the preferences of people with dyslexia on usingthe Web. Analyze, if any, different profiles of people with dyslexia and most significant accessibilitybarriers for them.We thank all participants and the Associação Brasileira de Dislexia forbeing an indispensable partner in this project.
