    1. 1. Christopher Bailey Dr. Elaine Pearson Teesside University [email_address] An Educational Tool to Support the Accessibility Evaluation Process
    2. 2. Main Issues <ul><li>Guide novice auditors through an evaluation, raise awareness of accessibility. </li></ul><ul><li>Compile a detailed list of checks based on testing for well known accessibility principles </li></ul><ul><li>Support a contextual approach to evaluation. </li></ul><ul><li>Our students need support with accessibility: </li></ul><ul><ul><li>Little existing knowledge of accessibility </li></ul></ul><ul><ul><li>Develop live websites for specific audiences </li></ul></ul><ul><ul><li>Accessibility personally a low priority </li></ul></ul><ul><ul><li>Limited access to disabled end users </li></ul></ul><ul><ul><li>Limited access to expert reviewers </li></ul></ul>
    3. 3. Functionality (1) <ul><li>The tool lists accessibility checks based on three evaluation contexts: </li></ul><ul><ul><li>User Group </li></ul></ul><ul><ul><li>Site Features </li></ul></ul><ul><ul><li>Check Categories </li></ul></ul><ul><li>For each check, the tool: </li></ul><ul><ul><li>States the impact the issue has on users </li></ul></ul><ul><ul><li>Provides instructions on how to perform each check </li></ul></ul><ul><ul><li>Assists auditor in interpreting result of any automated check </li></ul></ul><ul><ul><li>Includes a video ‘how to’ walkthrough </li></ul></ul>
    4. 4. Functionality (2) <ul><li>Auditor records results of checks as they progress. </li></ul><ul><li>Print a template, or completed evaluation report. </li></ul><ul><li>Supports multiple users </li></ul><ul><li>Supports multiple site evaluations. </li></ul><ul><li>User can save/retrieve evaluations. </li></ul>
    5. 5. Evaluate by User Group <ul><li>Auditor views prioritised checks for one user group </li></ul><ul><li>Compare different requirements of two user groups. </li></ul><ul><li>Importance of check is dynamic: </li></ul><ul><ul><li>Critical Checks: Complete barrier, significant annoyance to user. </li></ul></ul><ul><ul><li>Important Checks: Noticeable annoyance or inconvenience </li></ul></ul><ul><li>Allows auditor to see commonalities, but also identify exceptions. </li></ul>
    6. 6. <ul><li>Utilises the full database of checks, supporting the concept of universal accessibility </li></ul><ul><li>Checks are grouped to make process simpler and intuitive </li></ul><ul><ul><li>Design Checks: overall visual design, e.g.: colour contrast </li></ul></ul><ul><ul><li>User Checks: testing with a human element, e.g.: keyboard accessibility, image text alternatives </li></ul></ul><ul><ul><li>Structural Checks: structure of web pages, e.g.: semantic HTML </li></ul></ul><ul><ul><li>Technical Checks: coding elements, e.g.: valid mark-up, metadata </li></ul></ul><ul><ul><li>Core Checks: Overall accessibility of site, e.g.: site map, accessibility statement </li></ul></ul><ul><li>Considers roles in web development team </li></ul>Evaluate by Check Categories
    7. 7. Evaluate by Site Features <ul><li>Auditor selects elements of their site they wish to check, e.g.: data tables, forms. </li></ul><ul><li>Auditor selects content features of their website, e.g.: video files. </li></ul><ul><li>Checks are tailored to content of website: </li></ul><ul><ul><li>Prioritises relevant checks </li></ul></ul><ul><ul><li>Streamlines process </li></ul></ul><ul><ul><li>Increases relevance </li></ul></ul><ul><ul><li>Eliminates redundancy. </li></ul></ul>
    8. 8. Future Work <ul><li>“ Dogfooding” – Create accessible RIA </li></ul><ul><li>Further development of tool over next 2-3 months. </li></ul><ul><li>Used for teaching Post Graduate students. </li></ul><ul><li>Expanded to include checks for other contexts, e.g.: WCAG 2.0, Mobile Devices, RIAs. </li></ul><ul><li>Test the performance of the tool: </li></ul><ul><ul><li>Is it effective? </li></ul></ul><ul><ul><li>Are results consistent? </li></ul></ul><ul><ul><li>Compare with existing evaluation methods. </li></ul></ul>
    9. 9. Christopher Bailey Dr. Elaine Pearson Teesside University [email_address] An Educational Tool to Support the Accessibility Evaluation Process
    10. 10. AEA Interface (1) <ul><li>Example comparison of high priority checks for Dyslexia and Screen Reader User groups. </li></ul>
    11. 11. AEA Interface (2) <ul><li>For each check the following information is provided: </li></ul><ul><ul><li>Why the check is necessary </li></ul></ul><ul><ul><li>Step by step instructions on how to carry out the check </li></ul></ul><ul><ul><li>A video walkthrough </li></ul></ul>
    12. 12. AEA Interface (3) <ul><li>The AEA contains an integrated reporting mechanism so the auditor can record their results as they complete an evaluation. </li></ul>
