Accessibility is a crucial element that can make a difference and determine the success or failure of a digital business. The study was applied to 50 e-commerce sites in the top rankings according to the classification proposed by ecommerceDB. In evaluating the web accessibility of e-commerce sites, we applied an automatic review method based on a modification of Website Accessibility Conformance Evaluation Methodology (WCAG-EM) 1.0. To evaluate accessibility, we used Web Accessibility Evaluation Tool (WAVE) with the extension for Google Chrome, which helps verify password-protected, locally stored, or highly dynamic pages. The study found that the correlation between the ranking of e-commerce websites and accessibility barriers is 0.329, indicating that the correlation is low positive according to Spearman’s Rho. According to the WAVE analysis, the research results reveal that the top 10 most accessible ...

La evaluación de la accesibilidad se llevó a cabo para comprobar el cumplimiento de las directrices de la accesibilidad al contenido web establecido por la recomendación de las Web Content Accessibility Guidelines 2.0 (WCGA 2.0) del World Wide Web Consortium (W3C). El objetivo principal fue tratar de determinar si las universidades con mayor prestigio académico según el CEACES, se han preocupado de proporcionar información accesible a través de su página web para que pueda ser accedido por todos, independientemente de si el usuario tiene una discapacidad. En el estudio se aplicó la Metodología de Evaluación de Conformidad muy utilizada al probar la accesibilidad en sitios web. De las páginas web analizadas, se determinó que ninguna cumple con las pautas de accesibilidad requeridas, por lo tanto, las páginas no son accesibles. A partir de los resultados obtenidos, se ha llegado a la conclusión de que la mayoría de los sitios evaluados no alcanzan un nivel de cumplimiento aceptable, a pesar de ser todas ellas instituciones incluidas en la clasificación con mayor prestigio académico según el CEACES. Sin embargo las instituciones de Educación Superior ecuatorianas, tienen un nivel bajo de accesibilidad a las páginas web, pero apuestan por lograr una mejor accesibilidad de acuerdo con los parámetros propuestos por la WCAG 2.0. Pues el 8 de agosto de 2020, todos los sitios web ecuatorianos que presten un servicio público deben ser accesibles de acuerdo con las WCAG 2.0 en el Nivel AA.This article describes a study to assess the accessibility of the contents of the websites of ten universities located in the A and B categories, in Ecuador, according to the classification of Consejo de Evaluación, Acreditación y Aseguramiento de la Calidad de la Educación Superior de la Calidad de la Educación Superior (CEAACES). The accessibility assessment was carried out to verify compliance with the guidelines of accessibility to web content established by the recommendation of the Web Content Accessibility Guidelines 2.0 (WCGA 2.0) of the World Wide Web Consortium (W3C). The main objective is to try to determine whether universities with greater academic prestige as the CEACES, have been concerned to provide information accessible through its website so that all, regardless of whether the user has a disability, can access it. In the study applies Website Accessibility Conformance Evaluation Methodology (WCAG-EM) for websites. Of web pages analyzed, it was determined that none meet accessibility guidelines required, therefore, the pages are not accessible. From the results, it was concluded that the majority of sites tested do not reach an acceptable level of compliance; therefore, the pages are not accessible, despite being all institutions included in the classification with the highest academic prestige as the CEACES. However, the Ecuadorian Higher Education institutions have a low level of accessibility to web pages, but are committed to achieving better accessibility according to WCAG 2.0. Is important to know that on August 8, 2020, all Ecuadorians websites that provide public services should be accessible according to WCAG 2.0 Level AA

The method includes 63 accessibility features that should be met by the images, headings and tables, which are inserted through an online content editor. The compliance of these guidelines contributes to the creation of accessible content so that visually impaired people using assistive technologies can easily access the content. Furthermore, the results of this study provide criteria for those people who have the responsibility of selecting an accessible online content editor. The proposed method has made it possible to meet the objective set out in this research document and can be used to evaluate the accessibility of learning management systems and course management systems.

The accessibility assessment was carried out to verify compliance with the Web Content Accessibility Guidelines 2.0 (WCAG 2.0) published by the World Wide Web Consortium (W3C). The main goal of this study is to determine whether people with disabilities are able to access and use government websites. In addition, we considered the Website Accessibility Conformance Evaluation Methodology (WCAG-EM) to determine how easily a website can be accessed according to WCAG 2.0. The WCAG-EM provides guidance on how to use the methodology and considerations for specific situations. From the results, we conclude that the majority of the websites do not achieve an acceptable level of compliance. The websites of governmental institutions with the highest level of competitiveness do not show a greater level of web accessibility. Several non-compliance errors were found on the websites; by performing this evaluation, we have identified that there are major barriers for a large number of users. Therefore, there is significant work pending to make the websites examples of best practice in e-government sites.

In such a situation, a natural user interface can be used both to record the therapeutic movements performed by the patient, and to navigate in the web application. Nevertheless, it is necessary to assess the user experience to validate the system usability. The present paper describes an experiment to test the usability of a platform designed to enhance the recovery of patients after hip replacement surgery. The user experience is evaluated through several metrics (completion time and usability questionnaire) and the results are related to a sociodemographic questionnaire. A clustering approach is implemented to identify a relationship between the user’s profile and the interaction performance with the platform.

For students to improve the learning process from the knowledge transmitted in class, we propose a method to motivate the development of computer applications to reinforce the learning of new concepts. This research presents a method for evaluation of accessible video games. In order to evaluate accessibility in a videogame, the Web Content Accessibility Guidelines 2.1 will be considered, which includes barriers for users with cognitive disabilities. This category of users involves people with limited ability to process and memorize information, make decisions, or learn. The proposed method can be replicated for users with other types of disabilities and can be applied during the game development cycle to ensure a more inclusive and accessible product.

The trend of eHealth to digitize the services associated with healthcare are becoming more frequent in the same way users who access these services are people with disabilities and the elderly. An initiative that allows improving the quality of life of people are websites, but not all websites are accessible and inclusive. Failures in Web accessibility create exclusion barriers in groups of people. There are several studies on accessibility in which the guidelines suggested by Web Content Accessibility Guidelines (WCAG) 2.0 were not adequately applied. This study describes the web accessibility problems identified in 22 hospital websites according to the Webometrics ranking. In the evaluation process, a framework was applied to help in the evaluation of the websites proposed by the World Wide Web Consortium. In this work, several hospital websites and the level of accessibility were validated, the Website Accessibility Conformance Evaluation Methodology was applied to identify the ease with which a website can be accessed in accordance with WCAG 2.0 standards; of the sites evaluated, the type of patterns most violated in the analysis was the name, role, and value, which represents 13.4% followed by the guidelines of content, information and relationships without text with 12.8%. Due to the barriers encountered, this study presents the need to strengthen legislation and implement web accessibility best practices to make the websites inclusive, making content accessible to all users, including people with disabilities.

This study was applied to ten mobile applications, the most popular according to PCMAG. We propose to use the Web Content Accessibility Guidelines 2.1 through manual review and automatic review with the Google Play Store Accessibility Scanner validator for the Android. The evaluation results of the mobile applications indicate that the applications are not accessible because they do not comply with the minimum required level proposed by WCAG 2.1. The research proposes suggestions to improve and raise awareness among the designers of mobile applications, in such a way that more inclusive mobile applications accessible to all types of users are built.

Web accessibility is not concerned with the specific conditions of people who use the Web, but with the impact that their conditions have on their ability to use it. If the web interfaces of the Tele-rehabilitation platform for hip arthroplasty patients are not accessible enough, the patients will not be able to understand, perceive or operate adequately the platform to benefit completely of the physical therapy. The Web Content Accessibility Guidelines (WCAG 2.0) provides a set of rules and recommendations to help solve the problems of Web accessibility. Additionally, there are evaluation tools that allow identifying main web accessibility problems. These tools are best exploited when used by accessibility experts. The purpose of this research is threefold. First, to present the results of a web accessibility evaluation of the web interfaces of the Tele-rehabilitation Platform for Hip Arthroplasty Patients using three the evaluation tools: WAVE, AChecker and TAW. Second, to analyze the results presented by the tools according to the WCAG 2.0 guidelines to define a list of accessibility improvements. Third, to implement the improvements through the re-factorization of the existing code and re-testing the improved web interfaces to verify that they meet acceptable accessibility levels.

Teachers use the storytelling as a powerful literacy tool which engage children in making connections between academic content and pedagogy. This strategy is also useful to integrate the diversity of the classroom. Increasing or varying the types of materials available to children is another way to make the classroom more inclusive. This paper proposes a new approach for fostering interaction and inclusion development during shared reading. We sought to increase the interactivity of traditional tale books by incorporating elements of technology and storytelling. To develop prototypes we recruited 30 teachers divided into six groups. Each group worked with two challenges: (1) to incorporate technology into a traditional storybook and (2) create an interactive storytelling book for left-handed children. During five work sessions each group developed two proposals: The first proposal was designed with QR codes and the second with NFC tags and augmented reality patterns to facilitate left-handed activities among teachers and children. The proposals were evaluated in the classroom and with experts’ reviews, finding interesting results.

The trend of eHealth to digitize the services associated with healthcare are becoming more frequent in the same way users who access these services are people with disabilities and the elderly. An initiative that allows improving the quality of life of people are websites, but not all websites are accessible and inclusive. Failures in Web accessibility create exclusion barriers in groups of people. There are several studies on accessibility in which the guidelines suggested by Web Content Accessibility Guidelines (WCAG) 2.0 were not adequately applied. This study describes the web accessibility problems identified in 22 hospital websites according to the Webometrics ranking. In the evaluation process, a framework was applied to help in the evaluation of the websites proposed by the World Wide Web Consortium. In this work, several hospital websites and the level of accessibility were validated, the Website Accessibility Conformance Evaluation Methodology was applied to identify the ease with which a website can be accessed in accordance with WCAG 2.0 standards; of the sites evaluated, the type of patterns most violated in the analysis was the name, role, and value, which represents 13.4% followed by the guidelines of content, information and relationships without text with 12.8%. Due to the barriers encountered, this study presents the need to strengthen legislation and implement web accessibility best practices to make the websites inclusive, making content accessible to all users, including people with disabilities.

This study was applied to ten mobile applications, the most popular according to PCMAG. We propose to use the Web Content Accessibility Guidelines 2.1 through manual review and automatic review with the Google Play Store Accessibility Scanner validator for the Android. The evaluation results of the mobile applications indicate that the applications are not accessible because they do not comply with the minimum required level proposed by WCAG 2.1. The research proposes suggestions to improve and raise awareness among the designers of mobile applications, in such a way that more inclusive mobile applications accessible to all types of users are built.

The evaluated applications are related to the quality of the air we breathe. As a matter of fact, nowadays there exists a high number of free applications for mobile devices that provide information about the level of contamination that is affecting cities, as well as the concentration of each significant pollutant. However, not all those mobile applications are accessible. This study uses Accessibility Scanner of Google, applying the accessibility guidelines for mobile applications of Web Content Accessibility Guidelines 2.1. In this study, 10 mobile applications were evaluated, and it can be said that the obtained results can be seen as a useful, practical example of how to develop inclusive mobile applications.

Web accessibility is not concerned with the specific conditions of people who use the Web, but with the impact that their conditions have on their ability to use it. If the web interfaces of the Tele-rehabilitation platform for hip arthroplasty patients are not accessible enough, the patients will not be able to understand, perceive or operate adequately the platform to benefit completely of the physical therapy. The Web Content Accessibility Guidelines (WCAG 2.0) provides a set of rules and recommendations to help solve the problems of Web accessibility. Additionally, there are evaluation tools that allow identifying main web accessibility problems. These tools are best exploited when used by accessibility experts. The purpose of this research is threefold. First, to present the results of a web accessibility evaluation of the web interfaces of the Tele-rehabilitation Platform for Hip Arthroplasty Patients using three the evaluation tools: WAVE, AChecker and TAW. Second, to analyze the results presented by the tools according to the WCAG 2.0 guidelines to define a list of accessibility improvements. Third, to implement the improvements through the re-factorization of the existing code and re-testing the improved web interfaces to verify that they meet acceptable accessibility levels.

Teachers use the storytelling as a powerful literacy tool which engage children in making connections between academic content and pedagogy. This strategy is also useful to integrate the diversity of the classroom. Increasing or varying the types of materials available to children is another way to make the classroom more inclusive. This paper proposes a new approach for fostering interaction and inclusion development during shared reading. We sought to increase the interactivity of traditional tale books by incorporating elements of technology and storytelling. To develop prototypes we recruited 30 teachers divided into six groups. Each group worked with two challenges: (1) to incorporate technology into a traditional storybook and (2) create an interactive storytelling book for left-handed children. During five work sessions each group developed two proposals: The first proposal was designed with QR codes and the second with NFC tags and augmented reality patterns to facilitate left-handed activities among teachers and children. The proposals were evaluated in the classroom and with experts’ reviews, finding interesting results.
