Abstract :
The Web Content Accessibility Guidelines (WCAG) have been used by web developers to develop accessible web pages. However, touch screen accessibility varies with web site accessibility. This research is dedicated to the improvement of accessibility of e-assessment in mobile touch screen for blind users. We chose IMS´ Question and Test Interoperability specification (QTI) as a basis to generate the components of the e-assessment. We then extended the components to derive the Accessibility and Usability features Guidelines (AUG) using the WCAG. Specifically, we designed a prototype according to the derived AUG to check the accessibility for blind users. We analysed the results and found that the performance of the prototype is promising.
