En  Naming things to improve accessibility se explica: One thing you can do to improve the accessibility of your work is to always ensure things have accessible names. Unique and useful names, ideally, so that they can be used for navigation. In this post I’ll explain how browsers decide on the names for links, form fields, tables and form groups. Accessibility Tree When a user accesses your site, the server will send markup to the browser. This gets turned into trees. We’re probably all familiar with the DOM tree, a live representation of your markup, with all nodes turned into objects that we can read properties of and perform all sorts of functions on. What many people don’t know, is that there is a second structure that the browser can generate: the accessibility tree. It is based off the DOM tree, and contains all meta information relation related to accessibility: roles, names and properties. Another way to say it: the accessibility tree is how your page gets exposed to assistiv

En  Building Interactive HTML5 Videos podemos encontrar un reproductor multimedia que permite seleccionar los capítulos del vídeo, para saltar fácilmente entre secciones de un vídeo. Y en  Adding captions and subtitles to HTML5 video se explica cómo gestionar los subtítulos desde JavaScript.

BBC Subtitle Guidelines : Subtitles are primarily intended to serve viewers with loss of hearing, but they are used by a wide range of people: around 10% of broadcast viewers use subtitles regularly, increasing to 35% for some online content. The majority of these viewers are not hard of hearing.  This document describes 'closed' subtitles only, also known as 'closed captions'. Typically delivered as a separate file, closed subtitles can be switched off by the user and are not 'burnt in' to the image.  The Subtitle Guidelines describe best practice for authoring subtitles and provide instructions for making subtitle files for the BBC. This document brings together documents previously published by Ofcom and the BBC and is intended to serve as the basis for all subtitle work across the BBC: prepared and live, online and broadcast, internal and supplied.

La semana pasada asistí a las  III Jornadas INCLUTRAD de Accesibilidad, Discapacidad y Traducción , organizadas por la Universidad Pablo de Olavide en Sevilla Ramón Rodríguez, director de proyectos globales de la Fundación Universia presentó el IV Estudio Universidad y Discapacidad . Según este estudio, un 1,5% de la población universitaria presenta una discapacidad. El tipo de discapacidad más frecuente es la física con un 55,9%, seguida de las discapacidades psicosociales con un 26,5% y las discapacidades sensoriales con un 17,4%. Las jornadas se retransmitieron en directo por Internet. En todo momento hubo interpretación a la lengua de signos española. También se utilizó el sistema Webcaptioner para ofrecer transcripción en vivo. Más información: Sitio web de las jornadas . CERMI Andalucía participa mañana en Sevilla en la Inauguración de las III Jornadas ‘Inclutrad’ sobre Accesibilidad, Discapacidad y Traducción . III Jornadas INCLUTRAD 2019 .

Conviene recordar la primera regla de WAI-ARIA ( 2.1 First Rule of ARIA Use ): If you can use a native HTML element [HTML51] or attribute with the semantics and behavior you require already built in, instead of re-purposing an element and adding an ARIA role, state or property to make it accessible, then do so.  Under what circumstances may this not be possible? If the feature is available in HTML [HTML51] but it is not implemented or it is implemented, but accessibility support is not. If the visual design constraints rule out the use of a particular native element, because the element cannot be styled as required. If the feature is not currently available in HTML.

En  Understanding WCAG 2 Contrast and Color Requirements , se explican los requisitos de WCAG relacionados con el contraste y el color.

En  Automated Lies, with one line of code se da una buena explicación de los problemas o de las cosas que no hacen las herramientas automáticas de evaluación de la accesibilidad web: It should be universally understood that automated testing tools cannot offer complete test coverage for all possible accessibility issues on the web. Therefore it stands to reason that if you cannot automatically find all your site’s accessibility issues, you certainly cannot automatically fix all of them, either. This is extraordinarily simple logic. In fact, automatically fixing issues is even less likely to be successful than finding them. This fact is demonstrated within Mallet. While Mallet is extremely good at finding & fixing some issues, it is still limited to around 2-dozen types of ‘fixes’ that work on their own without any configuration. The remainder of Mallet’s fixes require some level of configuration. To put this into perspective, Tenon.io has approximately 200 accessibility tests that

En  Building the most inaccessible site possible with a perfect Lighthouse score desarrollan un ejercicio muy interesante: cómo crear un sitio web que sea lo más inaccesible posible pero que obtenga una puntuación perfecta en una herramienta automática de evaluación de la accesibilidad.

En  Does the universal symbol for disability need to be rethought? se explica el origen del símbolo universal de discapacidad y se discute la necesidad de adecuarlo a la sociedad actual: Ninety-three percent of people with disabilities don’t use a wheelchair, even though the universal symbol that identifies this group is a person in a wheelchair. Liam Riddler, a creative at London’s McCann office, points to his brother, who suffers from Crohn’s disease–a condition that causes inflammation of the digestive tract, potentially causing pain, severe diarrhea, fatigue, weight loss, and malnutrition. It’s an invisible disability: Nobody would know about it by looking at him. Most people don’t understand why he may need to use accessible toilets or take advantage of priority seating. Public ignorance of these invisible disabilities and the discrimination that results is what prompted Riddler and his colleague–McCann London’s deputy of art Lisa Carrana–to ask an obvious but difficult question:
