DCWA: TESTING TOOL FOR DETECTION AND CORRECTION IN WEB ACCESSIBILITY

Abstract

Web is most powerful source of information but Web users can even have disability, which may a ect them permanently or temporarily. Some have more di culties than others or simply if we say that person with disability (PWD) have their own problem accessing web. And there is a question comes in usability and accessibility of web for PWD. NowadaysWeb-designers have focused on designing the interface that is eye pleasant due to which the issues of web accessibility have been poorly addressing and it becomes problem because users do not have the equivalent ability to accesses and exploit the web content.Therefore several guidelines and recommendations have been introduced so that web content can be made more accessible and usable to all users Lots of initiatives have been taken in this direction of making websites accessible and usable but still the problem of the accessibility of Web pages is unattended by many sites. Evaluation of web sites becomes compulsory to determine that weather websites meets accessibility guidelines or not and this is done through web accessibility evaluation tools that are software programs or online services that help to determine this. Web accessibility evaluation tools are signi cantly able to reduce the time and e ort needed in carrying out evaluations. Moreover if we use these tools carefully throughout whole designing, implementation and maintenance part of development then these tools can help their users in preventing accessibility barriers, reporting the encountered barriers means they can improve overall quality of websites. Web Accessibility Evaluation tools can be classi ed as automatic and semi automatic. The automatic tools allow developers and designers to quickly evaluate websites for accessibility Lots of Evaluation tools are available in market but they have some drawbacks like they detect the accessibility issues and generate tips for developers but they don't have any e cient correction mechanism in built with them. A new tool DCWA is introduced that will do dual task of detecting the web accessibility issues as well as correcting them too that reduces the burden of developer to manually checking tags one by one.This multi function in DCWA makes it better than other available tools. Detection and corrections both are available in previous resources separately but the combination of these two is a key success to this tool. There are some matrixes on which the performance of various web accessibility evaluation tools is measured so there is a comparison between various evaluation tools. In general, the objectives of this research are: To develop a testing tool DCWA for detection and correction in web accessibility. To provide a comparative study on various web accessibility evaluation tools.
