While translation professionals are making a considerable contribution to that digital information richness, little evidence exists regarding their involvement in the achievement of a more accessible web for all. In this paper, we present the main results of the first empirical study on web accessibility conceived around a translation task. The experiment sought to particularly investigate the quality of image text alternatives produced by French translators with the help of two evaluation tools: aDesigner and Acrolinx. The assessment of their alt text proposals, carried out by seven screen reader users, suggests that using both tools helps translators to create more appropriate text alternatives than when trying to do so with only one tool or without any automated support. A more in-depth analysis of the data gathered shows that Acrolinx offers better guidance than aDesigner for translators to render images accessible.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121997343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Automated evaluation tools still require a significant manual element. There is also a significant expertise and evaluator effect. The Structured Walkthrough method is the translation of a manual, expert accessibility evaluation process adapted for use by novices. The method is embedded in the Accessibility Evaluation Assistant (AEA), a web accessibility knowledge management tool. Previous trials examined the pedagogical potential of the tool when incorporated into an undergraduate computing curriculum. The results of the evaluations carried out by novices yielded promising, consistent levels of validity and reliability. This paper presents the results of an empirical study that compares the reliability of accessibility evaluations produced by two groups (novices and experts). The main results of this study indicate that overall reliability of expert evaluations was 76% compared to 65% for evaluations produced by novices. The potential of the Structured Walkthrough method as a useful and viable tool for expert evaluators is also examined.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132058964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a quadriplegic person paralyzed neck down as a result of sudden accident and yet who manages to conduct competitive research in earth science, there may not be a better example of this statement than I. In addition, the recent advances in open online education (such as OCW, MOOC, edX) offer new opportunities for people with disability. One of the important challenges for those with disability, sometimes more than the handicap itself, is that they are often shut out from the general public education, and in the end, it is this lack of education that can be a limiting factor in one's life.\u0000 Online education can be one of many tools for non-disabled students, and while its effectiveness can be debated among educators and those alike, it can be the only means of accessing information for people with severe disability. Thus it should be explored and investigated further. In Korea, we are developing new online technology and inclusive contents for people with disability, especially in the areas of STEM education for college and precollege level learning. We believe that this is a step towards so-called universal design in higher education and independent living. Furthermore, it is expected that our innovative approach will not only help people with disability but also reach out to a wider community of general mass, including those that are willing to take extra effort to master college-level online courses, improve their scientific skills and expand their knowledge base, which will in turn lead to new job opportunities in this knowledge-based economy and society.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"8 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131912105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Real-time captioning provides deaf and hard of hearing (DHH) users with access to spoken content during live events, and the web has allowed these services to be provided via remotely- located captioning services, and for web content itself. However, despite caption benefits, spoken language reading rates often result in DHH users falling behind spoken content, especially when the audio is paired with visual references. This is particularly true in classroom settings, where multi-modal content is the norm, and captions are often poorly positioned in the room, relative to speakers. Additionally, this accommodation can benefit other students who face temporary or \"situational\" disabilities such as listening to unfamiliar speech accents, or if a student is in a location with poor acoustics.\u0000 In this paper, we explore pausing and highlighting as a means of helping DHH students keep up with live classroom content by helping them track their place when reading text involving visual references. Our experiments show that by providing users with a tool to more easily track their place in a transcript while viewing live video, it is possible for them to follow visual content that might otherwise have been missed. Both pausing and highlighting have a positive impact on students' scores on comprehension tests, but highlighting is preferred to pausing, and yields nearly twice as large of an improvement. We then discuss several issues with captioning that we observed during our design process and user study, and then suggest future work that builds on these insights.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122799370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
