Information is becoming too much to actually make sense and this leads to an increasing demand of Smart Data. We can intend Smart Data as information obtained by large data and extracted by intelligent algorithms to meet people needs. This concept easily matches with well-known accessibility issues, solutions and techniques. Moreover, Smart Data is an emerging solution to prevent the large amount of data from becoming a new challenge in the e-accessibility field. In this context, my research is devoted to apply Smart Data to improve e-accessibility in a mobile crowdsourcing and sensing application designed to support users with disabilities in avoiding urban accessibility barriers.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"28 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":"133764525","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}

Thus, accessibility and usability features become even more critical to a Web application's success. Researchers have been worried in providing mechanisms to serve as guidelines that Web systems should provide, in terms of usability and accessibility requirements. However, there not exists an instrument to provide a measure to help the specialists to verify how much these requirements are presented in a Web system. In this paper, we describe HEUA, a proposed questionnaire to assess the usability and accessibility of existing (or legacy) Web systems, to support measuring how much effort a Web system needs to be improved.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"12 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":"114622401","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}

In this paper we present our efforts of making the speech translation of mathematical formulas a first class citizen in ChromeVox, a general screen reader for the Chrome browser. We exploit ChromeVox's ability to handle alternative representations of DOM elements for translation of mathematical content given in a variety of web formats into uniform utterances. We present a format of flexible and adaptable speech rules that support the customization of aural rendering of mathematics and introduce a specially semantically enriched representation of expressions that allows for a more natural reading experience. To further aid understanding of the math we exploit ChromeVox's idea of letting users engage with content on different levels of granularity to enable interactive exploration of complex mathematical formulas.","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":"121435020","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}

However, little is known about how effective is for identifying accessibility problems. Our experience, informed by a series of studies with blind users, corroborates that a website with a significant number of guideline violations can be perceived as accessible, and on the contrary, some participants may not perceive a highly accessible website as accessible. Accessibility guidelines are often criticised by their partial coverage and questionable validity. However, we should be very careful about making categorical statements in this regard as there are a number of variables that may introduce biases in user tests. We identify sources of bias related to user expertise, the experimental setting, employed language and reporting that, if not adequately controlled, may influence on the validity and reliability of the evaluation results. We discuss the limitations and practical implications of user testing with blind users for web accessibility evaluation.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"1 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":"123269154","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}

Depending on the video, required descriptions can be omitted because these may not fit in the durations of \"gaps\" in the video soundtrack (i.e. \"void\" spaces between dialogues or important sound elements). To address this issue, we present an exploratory work that focuses on the usage of \"artificial\" pauses in audio-described videos. Such pauses occur during the playing of the video so as to transmit more audio-descriptions. Our results show artificial pauses offer a good acceptability level as well as a low disturbing effect.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"201202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116487442","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}

A new component (GenURC) within the URC environment generates a personal and context-driven user interface in a two-step process. A rich grouping file is used as an intermediate user interface description, containing \"flexion points\" for runtime adaptations based on the use context.

They depend on screen readers to convey the table information. Screen readers present content linearly to users, but if the table is large, the user may have long forgotten the heading before the last row is read. Even in table navigation mode, it can still be confusing if the table is not marked up properly. Though there are guidelines for web developers to create accessible web tables, some authors may still not properly mark up the web tables. There are also lots of legacy web tables that are not designed with accessibility in mind. These unstructured web tables arouse a need for web accessibility improvements. Existing solutions mainly focus on interpreting tables by screen readers and providing guidelines to create accessible web table, so there is a research gap on how to adapt unstructured table to improve web accessibility. In this regard, we propose a method to extract the structure from these tables and re-organize them into multiple levels of abstractions so that the visually impaired users can access the tables level by level by selecting the corresponding option number. This has enhanced the table content understanding for people without visual perception and has greatly improved web accessibility of unstructured web table for both PC users and mobile users with visual disabilities.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132656015","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}

Each employee is required to learn from these sources to work effectively and to contribute to the company's business. Crowdsourcing services have a great potential to improve workplace accessibility by providing captions for meeting videos, describing key diagrams, and converting scanned materials into text files. However, it is risky to expose confidential materials in a public crowd. Crowdsourcing to employees who have knowledge and expertise may solve the issue of confidentiality, but it is difficult to reach them to access their \"niche\" spare time for tasks given their busy work schedules. Therefore, we propose a crowdsourcing platform to securely disseminate tasks to employees by inviting them to do microtasks. The basic strategy is akin to Web advertising. The system automatically suggests tasks to employees as a part of intranet webpages and in e-mail clients by considering work contexts, employee interests and expertise, and the security of the materials. We will first discuss the pros and cons of intraorganizational crowdsourcing and then propose the new crowdsourcing platform.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124862839","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}

These difficulties can be overcome by language exercises. Typically, they come in the form of books. Hence, they are static and do not adapt to a child's specific needs. We present Dyseggxia, a game for mobile devices for children with dyslexia. It features five different exercises, which were derived from previous research on dyslexic errors. A study with 12 children with dyslexia confirmed that the game is fun and more attractive than traditional exercises. When playing, the exercises adapt to the specific difficulties of the individual player. The game is available for free for iOS and Android and it has been adopted into the program of institutions which support children with dyslexia. This is the first time English and Spanish reinforcement exercises are presented in an adaptive and fun-to-do way.","PeriodicalId":339122,"journal":{"name":"International Cross-Disciplinary Conference on Web Accessibility","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121301031","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}

However, as Hollier [4] notes, the transition to Web accessibility requires a concerted effort to address a range of potential barriers to adoption. This paper reports on the implementation of a university accredited non-award certificate program to address several of the identified issues likely to impact the achievement of the Australian Government's NTS goals and timelines.
