Accessibility to mobile interfaces for older people

  1. 1. Accessibility to mobile interfaces for older people Jose-Manuel Díaz-Bossini, Lourdes Moreno Labda Group, Computer Science and Engineering Department Universidad Carlos III de Madrid Vigo, 13 November 2013
  2. 2. Contents  Introduction and Motivation  Background  Proposal  Conclusions and Future Work 2
  3. 3. Introduction and Motivation  Exponential growth of the elderly population that suffers from age-related disabilities  This problem will be even bigger when middle-age population becomes the new elderly population.  New technologies and devices evolves faster than accessibility issues are addressed 3
  4. 4. Background  Accessibility and older people  There is a lack of accessibility guidelines in the mobile applications context: literature, best practices and guidelines.  W3C is working on providing guidance to apply its Web Content Accessibility Guidelines (WCAG) via the Mobile Web Application Best Practices (MWABP) and Mobile Web Best Practices (MWBP) 4
  5. 5. Proposal  A set of guidelines to keep in mind in order to achieve accessibility in mobile interfaces for older people.  An accessibility study of three mobile native Apps on android that modify the default interface for another more accessible one. 5
  6. 6. Proposal Accessibility guidelines  Accessibility guidelines of mobile Apps for the elderly  We propose an Accesibility Checklist for mobile Apps for the elderly : set of 17 checkpoints collected from 3 source research works: ① World Wide Web Consortium (W3C) guidelines. ② Android Accessibility Practices. ③ Age-centered Research-Based Design Guidelines (2005, Panayiotis, Z. et al.) 6
  7. 7. Proposal Accessibility guidelines ① W3C criteria (7 criteria): • Providing a text equivalent for every non-text element • Use clear and simple language • Do not create periodically auto-refreshing pages, unless you have informed the user and provided a means of stopping it 7
  8. 8. Proposal Accessibility guidelines ② Android Accessibility Practices (4 criteria) • Add descriptive text to user interface controls • Audio prompts accompanied by another visual prompt or notification ③ Age-centered Research-Based Design Guidelines (6 categories) • Provide larger targets • Provide ample time to read information • Highlight important information 8
  9. 9. Proposal An accessibility study of mobile Apps  EXPERIMENTAL DESIGN 1. Object of study:  An accessibility evaluation of 3 mobile native Apps that modify the default interface, turning it into a more accessible and friendly one for elderly people 2. Experiment Context • Nexus 4 Smartphone with Android 4.2.2. • TalkBack services • Explore by Touch system feature 9

  13. 13. 13 Proposal An accessibility study of mobile Apps  Summary and Interpretation of Findings  The results of study indicate Big Launcher is the most accessible for older people of the three applications.  In the medium term, we’ve got Frontillo. It accomplish with many of the criteria established.  The accessibility for Android App is a good application but it focuses mainly on blind people, so it’s not the best option for older people.
  14. 14. Conclusions  From this study, we provide: • A checklist of accessibility guidelines to evaluate mobile Apps for elderly people • Evaluation of three mobile native Apps that modify the default interface, turning it into a more accessible for elderly people  Apps should be accessible in order to prevent social exclusion and to encourage the access of elderly and disabled people to the technologies  Accessibility requirements should be addressed early on the design phase in the development process.  Future work 14
