El pasado 17 de septiembre de 2020 se celebró el Inclusive Design 24:
A free 24-hour online event for the global community. It celebrates inclusive design and shares knowledge and ideas from analogue to digital, from design to development, from planners to practitioners, and everything and everyone in between.
Todos los vídeos del evento están disponibles en la lista Inclusive Design 24.
People often include screen reader users in the much larger group of keyboard-only users. Whilst this is correct (most screen reader users don’t use a mouse), it also creates a false impression of the way screen reader users navigate content.
To help explain this, I’m going to generalise and refer to the two following groups of people:
- Keyboard users: people who don’t use a mouse but can see the content.
This is a massive over-simplification of the different groups, but the ability to see the content or not is the crux of the difference in navigation.
- Screen reader users: people who don’t use a mouse and can’t see the content.
Las Pautas de Accesibilidad del Contenido Web, Web Content Accessibility Guidelines (WCAG) 2.1, tiene tres criterios de éxito sobre el contraste mínimo de los elementos de una página web:
Sin embargo, no dice nada de lo contrario, el contraste máximo. Pero ¿pueden existir personas que tenga problemas cuando el contraste sea excesivo?
Sí, hay personas que pueden tener problemas.
En Accessibility and me: Marian Foley podemos leer:
I've been partially sighted since I was 9, and need large text and low contrast colours to be able to work. My requirements are quite unusual for someone with sight loss, as most visually impaired users need high contrast colours. My retinas can't process colour contrast properly, and spending more than a couple of minutes looking at high contrast material (web pages, documents, anything with regular stripes, spots or checks) gives me a splitting headache and motion sickness.
Y en este mensaje de Twitter:
Does anyone who works in accessibility for @Microsoft or @Apple follow me? I'd like to discuss settings needed for those with Irlen Syndrome. To us, text wobbles like an optical illusion. Luckily, it can be fixed with low-contrast color overlays, but that feature doesn't exist.
Según la Wikipedia, el síndrome de Irlen es:
Irlen syndrome, occasionally referred to as scotopic sensitivity syndrome (SSS) or Meares-Irlen syndrome, very rarely as asfedia, and recently also as visual stress, is a proposed disorder of vision.
En Así es como usa Internet un ciego. Al menos algunos se cuenta:
Si bien es cierto que la mayoría podemos hacernos una ligera idea de las incomodidades a las que se ven sometidas las personas que padecen algún tipo de discapacidad visual, lo cierto es que pocos somos conscientes de cómo estos individuos se desenvuelven en determinados entornos y actividades.
Es el caso de la navegación por Internet, un acceso sin el que muchos seríamos incapaces de “vivir” y que Facebook y otras plataformas tratan de poner más fácil. Pero, ¿en qué consisten estas iniciativas? ¿Cómo lo logran exactamente? ¿De qué herramientas se valen? Analizamos el contexto actual y les preguntamos a algunos de ellos.
This article reports the results of a study comparing evaluation accessibility plugins extensions for the Chrome web browser. Eight of the most well-known tools among developers were chosen. All tools are free or available under an open-source license, and work with the Chrome browser. The tools were compared based on their feature set, their usability and their evaluation results of ten of the Alexa top websites. We found that individual tools still provide limited coverage of the success criteria; the coverage of success criteria varies quite a lot from evaluation engine to evaluation engine; what are the most and least covered success criteria in automated evaluations. After analysing the results, we highly recommend to use more than one tool (with a different engine) and to complement automated evaluation with manual checking.
Según Eric Eggert, los accessibility overlay basados en inteligencia artificial no cumplen lo que prometen. Lo cuenta en su vídeo 5 False Claims 1-Line “AI” Accessibility Script Vendors Make:
Y el inicio de la transcripción:
They claim to be the be-all and end-all of all accessibility worries: “AI” accessibility tools. They say they provide “100% WCAG 2.1 compliance”. They say it only takes one line of JavaScript to “fix your website for accessibility”.
Who are “they”? VC-backed companies that promise affordable, effortless compliance for your website. If you think “that sounds too good to be true”, you’re right. It is indeed quite the opposite of true.
Here are five claims that “AI” accessibility script vendors make that are misleading or completely untrue.

Assistive technologies (ATs), which are hardware and software that help us perceive and interact with digital content, come in diverse forms. ATs can use a whole host of user input, ranging from clicks and keystrokes to minor muscle movements. ATs may also present digital content in a variety of forms, such as Braille displays, color-shifted views, and decluttered user interfaces (UIs).
One more commonly known type of AT is the screen reader. Programs such as JAWS, Narrator, NVDA, and VoiceOver can take digital content and present it to users through voice output, may display this output visually on the user’s screen, and can have Braille display and/or screen magnification capabilities built in.
If you make websites, you may have tested your sites with a screen reader. But how do these and other assistive programs actually access your content? What information do they use? We’ll take a detailed step-by-step view of how the process works.
Este dato se puede leer en el artículo Microsoft Reveals 6.1% Disability Representation For The First Time:
A newly released report from Microsoft reveals that 6.1 % of the company’s U.S. employees self-identify as disabled, meaning they have a physical, mental or cognitive disability. If you’re not quite sure how to put that number in context, that’s because few companies ever disclose similar numbers. This is the first time Microsoft has included disability in their annual diversity and inclusion report—and although the number may be modest, its significance will be understood worldwide.
[...]
Microsoft already employs people with all types of disabilities and is actively looking for new ways to be inclusive. The company has slowly and persistently chipped away at the issue since Satya Nadella became CEO in 2014. It takes patience and persistence to move the needle. Even the basics can’t be taken for granted. Many Americans don’t know that most disabilities are not visible, likely because they are not openly discussed and can be a source of shame or stigma. “Diabetes, dyslexia, and depression are three great examples of this. To understand our representation, we need data which means cultivating a workplace where employees can be confident, have pride in their disability and ultimately, confidentially self-identify whether they have a disability or not,” says Lay-Flurrie.
[...]
Microsoft defines disability, using the definition of disability from the World Health Organization in both in internal conversation and external conversations: “Disability is not just a health problem. It is a complex phenomenon, reflecting the interaction between features of a person’s body and features of the society in which he or she lives.”
In case you don’t make it all the way to the bottom, I feel, based on the results of testing each player (and comparing to my own Accessible Video Player project), that relying on native video players should be used with caution. This is my opinion stemming from experience, but I found most to have poor keyboard and screen reader support, which may lead to frustrated users.
There were a lot of inconsistencies across the board as far as keyboard and screen reader support. Some lose focus when the video controls receive focus then fade away, forcing the user to re-position themselves to adjust playback. Others did not trap keyboard focus in full-screen mode, leading to a similar situation as an inaccessible modal window allowing content to be accessed "behind" the window. One player in particular featured very awkward keyboard support where controls were visible on the screen but could not be focused.
El curso gratuito ¿Cómo diseñar y programar sitios web accesibles? tiene el siguiente contenido:
It’s easy to think about a layout as being a primarily visual concern. The header goes up top, the sidebar is over here, the call to action is in an overlay on top of the content (just kidding). Grids, borders, spacing and color all portray valuable visual data, but if these hints to the structure of a page are only visible, some users may find your content unintelligible.
You can experience this first hand if you try using a screen reader on the web. When I fired up VoiceOver on my Mac and took it out for a test drive, I realized that to a screen reader user, a lot pages are just a big heap of ‘content’, missing helpful organizational cues.
The experience can be kind of like listening to a long rambling story without any indication to what details are important or related to the main thread of the story. Halfway through the story, you aren’t sure whether it’s worth it to keep listening because you don’t know if you’ll even find what it is you’re looking for. In the context of a website, your screen reader might be halfway through reading you a list of 50 sidebar links when you start wondering if there is any valuable content on the site at all.
Experiences like this are caused by websites that are built with layouts that are only visual. Ideally, however, our visual layouts should point to an underlying organizational model of our content. They should be visual indicators for a conceptual model. The visual indicators are just one way of revealing this model. The Web Accessibility Initiative’s ARIA (Accessible Rich Internet Applications) project provides alternative indicators to users who may need them.
I’ll walk through how to make use of these indicators to make a simple web page easy to use, navigate and read for users of assistive technology. All the example code is available on github.
En Web Content Accessibility Guidelines (WCAG) 2.2 Draft for Review, el W3C explica las novedades de WCAG 2.2:
En What’s New in WCAG 2.2 y WCAG 2.2 Overview and Feedback se analizan las novedades que tiene WCAG 2.2 hasta el momento actual, ya que todavía es un borrador, no es la recomendación final.
Interesante el vídeo A WCAG Overview — Web Content Accessibility Guidelines (WCAG) 2.1 and 2.0 Explained:
For people who do not experience barriers, it can be difficult to empathize with the challenges that people with disabilities often face when navigating the Web. The Accessibility Maze was created to help those new to web accessibility experience firsthand what it is like to encounter those barriers. The game introduces a number of common barriers players must work around, mirroring the experience of those who encounter these obstacles daily, and provides quick lessons on how to avoid or correct them.
In creating the game we wanted to ensure it would be accessible. Gaming being one of the more challenging areas in which to address accessibility, the Accessibility Maze has been created to be playable with a current screen reader, using only a keyboard, and to demonstrate strategies for making games accessible.
¿Te has planteado qué pasaría si de repente no pudieras utilizar la pantalla de tu ordenador? ¿Te ves capaz de manejarlo sin poder verlo? ¿Y un iPhone? ¿Es eso posible?
En este vídeo veremos cómo las personas ciegas hacemos uso de la tecnología, y cómo ésta nos permite ser mucho más independientes siempre que sea accesible. Adéntrate conmigo en una realidad diferente que seguro te sorprenderá.
Según Introduced Online Accessibility Act Would Amend ADA, Clarify Web Accessibility Compliance Standards, en EEUU se ha propuesto Online Accessibility Act, una nueva ley sobre accesibilidad web que se añadirá a la famosa Americans with Disabilities Act (ADA) de 1990.
El borrador de la ley añadirá un nuevo título de sección:
TITLE VI—CONSUMER FACING
WEBSITES AND MOBILE APPLICATIONS OWNED OR OPERATED BY A PRIVATE ENTITY
Que entre otras cosas, dice:
(1) IN GENERAL.—A consumer facing website or mobile application shall be considered compliant under the requirements of this section if such website or mobile application is in substantial compliance with the Web Content Accessibility Guidelines (referred to in this title as WCAG) 2.0 Level A and Level AA standard established by the Accessibility Guidelines Working Group, or any subsequent update, revision, or replacement to the WCAG 2.0 Level A and Level AA standard published by the World Wide Web Consortium or successor organization.
Según una nota de prensa de la Fundación Once y Por Talento Digital:
Un total de veintiséis personas con discapacidad de Madrid, Barcelona y Valencia han finalizado el curso ‘Programación para No Programadores’, que se lleva a cabo dentro de la iniciativa Por Talento Digital (http://www.portalentodigital.es/) de Fundación ONCE, con la colaboración de Inserta Empleo y el proveedor de formación OPINNO.
El curso comenzó el pasado mes de diciembre con medio centenar de alumnos de los que la mitad lo han terminado. En total han sido 800 horas de formación, desarrollada en tres ciudades como son Madrid, Barcelona y Valencia. Además, ha contado con el apoyo de Fundación Vodafone España y Mastercard.
El curso Programación Web Full-Stack para no programadores no requería formación previa en programación precisamente para dar una oportunidad de reciclar profesionalmente a las personas que no venían del terreno tecnológico, ofreciéndoles así el reto de formarse en una de las profesiones tecnológicas más demandadas actualmente en el mercado laboral.
Tuvo dos fases. La primera contaba con la cofinanciación de la Fundación Vodafone España, y durante sus 250 horas sirvió para fijar los conceptos y tecnologías básicas de programación, a través de lenguajes como c# o java.
La segunda fase, que comienza ahora, es una formación especializada de 550 horas en programación web, front y backend, donde los alumnos aprenderán fundamentos web basados en estándares como Javascript, CSS, html, Angular o next js.
Para esta nueva modalidad online se está utilizando la plataforma Discord (que permite crear grupos de trabajo, aulas, etc.), así como la extensión Visual Studio Code para compartir el código de desarrollo. Ha sido necesario implementar algunas adaptaciones de accesibilidad para asegurar el acceso en igualdad de condiciones a todo el alumnado en este nuevo formato.
Por ejemplo, para una alumna con discapacidad auditiva en la sede de Madrid se ha incorporado una herramienta de subtitulado automático que permite seguir las explicaciones del profesor. Además, para otro alumno sordo signante de Barcelona se ha dispuesto una herramienta para que pueda contar con la intérprete de lengua de signos en remoto.
Además de la formación teórica, ha habido un fuerte componente de toma de contacto con el mundo empresarial. Así, han impartido masterclasess a los beneficiarios responsables de Microsoft, Between, Avanade, El Corte Inglés, Deloitte, Souji y Nutrilieve.
Por otro lado, se organizaron 3 sesiones de Speed Dating a través de Zoom, en las que participaron profesionales de Everis, Avanade, BMAT, RECUBIK, Super Squad Interactive, Pavapark, ALZIS, KIWA, Everycode, GFI, Fundación Universia, Nutrilieve, Go Zero Waste, Smart Monkey, Jump Data Driven, It Will Be y Voices of Leaders. El objetivo de estas sesiones era que las empresas conociesen a los alumnos para poder ofrecerles prácticas no laborales que completen la formación teórica que han recibido.
El próximo 17 de noviembre de 2020 participaré en el Seminario Permanente sobre Discapacidad PUDH-FCPyS UNAM Discapacidad y TIC's: ¿Exclusión virtual y digital? organizado por la Universidad Nacional Autónoma de México. Este seminario comienza el 3 de noviembre.
