aDesigner is a disability simulator that helps web designers ensure that their pages are accessible and usable by the visually impaired.The tool looks at such elements as the degree of color contrast on the page, the ability of users to change the font size, the appropriateness of alternate text for images, and the availability of links in the page to promote navigability. The tool also checks the pages's compliance with accessibility guidelines. The result of this analysis is a report listing the problems that would prevent accessibility and usability by visually impaired users. In addition, each page is given an overall score. With this information, web developers get immediate feedback and can address these obstacles before the pages are published.
