Web accessibility guidelines have textual representation and provide little support in systematic analysis and usage. The study hypothesizes that the guidelines can be reorganized and represented using the goal oriented technique and design patterns which will allow their usage in a more systematic manner and accommodate detailed analysis of the guidelines with other competing goals. For this study, knowledge from web designers’ experiences in using the guidelines, researchers’ findings, and the actual guidelines have been amalgamated. Six web designers have been consulted on a one-on-one basis and difficulties in using the guidelines for (1) specific scenarios, (2) systematic application, and (3) detailed systems analysis have been reported. Goal oriented modeling and design patterns have been introduced for (1) graphical representation of the guidelines using goal graphs, and (2) keeping the technical details separate from the goal graphs. The proposed representation allows for the accessibility guidelines to be systematically applied into interface design, and systems design using the goal oriented modeling technique.
