ACCESSIBLE - Applications Design and Development

Web accessibility assessment Tool – WaaT

Developed by CERTH/ITI

WaaT is a Web applications assessment tool for the accessibility verification of Web applications. For the convenience of ACCESSIBLE users two different versions of the tool are being supported. Thus, a standalone version in addition to a web based version that can be accessed through the ACCESSIBLE portal are offered to potential users. So, each system user will be able to define some input parameters /rules/ constraints regarding the overall assessment process (e.g. evaluate a web page according to a specific WCAG 2.0 accessibility technique, or according to a specific disability, AEGIS and ACCESSIBLE personas, etc.).
