The need for checking both usability and accessibility of Web sites is widely recognized, approved and recommended by several official organizations. What should really be more recognized or addressed is an equal need for repairing the usability and accessibility defects that have been detected. Within the Destine suite, we developed a tool allowing to repair the HTML source code of a page with user interaction. Thanks to an improved version of the Guideline Definition Language (GDL), the accessibility guidelines are not hard-coded, so that our tool can deal with any existing or future standards [ABSTRACT FROM AUTHOR]

Almost all projects can be considered as cooperative undertakings. Their strategic management as well as the daily operations causes numerous interactions to occur, either among persons or among persons and resources. These interactions have been studied from various viewpoints but few researchers have focused on their visualization. The graphical representation of the cooperation is however a powerful tool to help the project participants to get a correct understanding of the situation. This paper proposes thus a structuring framework (IVF - Interaction Visualization Framework) of the visualization techniques used to display such interactions. Three basic axes of classification are used to structure the study. Which objects are visualized? Why are they visualized? How are they visualized? For each axis, several properties have been identified and the admitted values have been specified. This work can be considered as a first step towards a structured view of the ‘visualization of cooperation' domain. [ABSTRACT FROM AUTHOR]

A system for automatically evaluating the usability and accessibility of web sites by checking their HTML code against guidelines has been developed. All usability and accessibility guidelines are formally expressed in a XML-compliant specification language called Guideline Definition Language (GDL) so as to separate the evaluation engine from the evaluation logics (the guidelines). This separation enables managing guidelines (i.e., create, retrieve, update, and delete) without affecting the code of the evaluation engine. The evaluation engine is coupled to a reporting system that automatically generates one or many evaluation reports in a flexible way: adaptation for screen reading or for a printed report, sorting by page, by object, by guideline, by priority, or by severity of the detected problems. This paper focuses on the reporting system. [ABSTRACT FROM AUTHOR]
