¿Para cuándo EN 301 549 actualizado para cumplir con EAA?
En EN 301 549 V3 the harmonized European Standard for ICT Accessibility podemos leer:
EN 301 549 will be revised with the aim to publish V4.1.1 in 2025 in support of the European Directive (EU)2019/882 on the accessibility requirements for products and services (the European Accessibility Act), as a response to the European Commission Mandate 587. The revision work item of ETSI Technical Committee Human Factors (TC HF) can be seen via the Portal, along with its target schedule.
Pero ya estamos a mediados de 2025, quizás sea mejor pensar en el 2026.

Diferencias entre WCAG, EAA y EN 301 549
WCAG (Web Content Accessibility Guidelines) | EN 301 549 (Standard) | EAA (European Accessibility Act) | |
---|---|---|---|
Type | Global standard and technical guidance (also an ISO standard) | Voluntary European standard for ICT accessibility | Legally Blind EU directive |
Purpose | Defines how to make web content and apps accessible | Defines accessibility requirements for ICT: websites, software, hardware, and documents | Requires accessibility of key digital and physical services |
Legal Staus | Not a law, but widely referenced in regulations and policies | Not a law, but used to demonstrate conformance with EU accessibility requirements | Enforceable law across all EU member states |
Scope | Web content: text, images, forms, navigation, etc. | ICT: websites, documents, software, mobile apps, hardware, telecoms | Consumer-facing products and services (e.g., banking, e-commerce, terminals) |
Relationship | Referenced by EN 301 549 and often cited in laws like the EAA | References WCAG for web content; supports public procurement and regulatory alignment | References standards like EN 301 549 and WCAG to define accessibility |

Multa a accessiBe por publicidad engañosa
The Federal Trade Commission has approved a final consent order against accessiBe Inc. and accessiBe Ltd. (accessiBe). AccessiBe claimed the plug-in accessWidget can make any website compliant with Web Content Accessibility Guidelines (WCAG). The order prohibits accessiBe from making misleading claims and requires the company to pay $1 million.The FTC’s January 2025 proposed complaint alleged that despite the company’s claims, accessWidget did not make all user websites WCAG-compliant and these claims were false, misleading, or unsubstantiated. In addition, the complaint alleged that accessiBe deceptively formatted third-party articles and reviews to appear as if they were independent opinions and failed to disclose the company’s material connections to the supposedly objective reviewers.

Android 16 y las aplicaciones adaptativas
The upcoming Android 16 update introduces a significant change to how applications handle screen orientation and resizability. Previously, apps could restrict their behavior - for example, locking themselves to portrait mode or being non-resizable at the platform level. However, Android 16 is removing this ability, moving toward a consistent model where all apps are expected to seamlessly adapt to various screen sizes and orientations.This initiative aligns with Android’s broader vision of supporting a diverse ecosystem of devices, from foldables to tablets to desktop-like experiences. While this is a positive step forward, especially for accessibility and usability, it brings both challenges and opportunities for app developers.

Resultados del estudio The WebAIM Million 2025
94.8% of home pages had detected WCAG 2 failures. This improved slightly from 95.9% in 2024. Over the last 6 years, the pages with detectable WCAG failures have decreased by only 3.1% from 97.8%. These are only automatically detected errors that align with WCAG conformance failures with a high level of reliability which suggests that the rate of full WCAG 2 A/AA conformance was certainly lower.

Ejemplo de cómo la administración pública exige accesibilidad, pero luego no la aplica
En el siguiente vídeo se explica cómo la administración pública exige una accesibilidad que luego ella misma no cumple. El vídeo habla de la accesibilidad física, pero lo mismo se puede decir de la accesibilidad digital, es decir, de los sitios web y las aplicaciones para dispositivos móviles.

Cuando poner una rampa es más complicado de lo que parece
El siguiente vídeo explica muy bien lo complicado qué puede ser poner una rampa para hacer accesible una escalera de simplemente seis peldaños. En el mundo digital, en los sitios web y las aplicaciones para dispositivos móviles ocurre algo parecido: solucionar algo que está mal hecho y no es accesible puede suponer mucho trabajo.

Elementos nativos de HTML que mejoran la accesibildiad
En Cool native HTML elements you should already be using se presentan algunos elementos nativos de HTML que no requieren montañas de código adicional y que, si son aceptados por el navegador web, deberían mejorar la accesibilidad de las páginas web:
I’m constantly surprised by the native HTML spec. New features are regularly added, and I often stumble on existing, handy elements. While often not as versatile as their JS counterparts, using them avoids bloating your app with extra Javascript libraries or CSS hacks.
If this article helps just a single developer avoid an unnecessary Javascript dependency, I’ll be happy. Native HTML can handle plenty of features that people typically jump straight to JS for (or otherwise over-complicate).
I cover some great HTML elements in this article — modals, accordions, live range previews, progress bars and more. You might already know some of these, but I bet there’s something new here for you too.

Un poco de historia sobre WCAG
The first iteration of WCAG was published in 1999, just eight years after Tim Berners-Lee published the initial draft specification for HTML and just six years after the MOSAIC web browser was first released. Two of WCAG 1.0’s three editors, Wendy Chisholm and Gregg Vanderheiden, were at the Trace R&D Center, at the time affiliated with the University of Wisconsin-Madison.Before work began on WCAG under the auspices of the W3C, Chisholm and Vanderheiden had already created eight iterations of what they called the Unified Web Site Accessibility Guidelines. Prior to those guidelines, Vanderheiden had published an article in January 1995 titled “Design of HTML (Mosaic) Pages to Increase their Accessibility to Users with Disabilities Strategies for Today and Tomorrow,” which identifies a series of common accessibility barriers and provides design or code solutions. (Incidentally, some of the problems identified remain things the web struggles with.)But it’s important to understand that Vanderheiden, Chisholm, and the Trace Center weren’t unique visionaries who stood separate from the world. They were part of a community that, from its earliest days, understood and valued accessibility.Vanderheiden had attended at the Second International WWW Conference: Mosaic and the Web in beautiful Chicago, Illinois in October 1994 — just a few months before his January 1995 article. So did Paul Fontaine and Mike Paciello, both also speaking on disability and accessibility. At that conference, Tim Berners-Lee identified accessibility as an important focus area as the web continued to grow and develop. Accessibility was very much in the air in the formative stages of the web.That was a quick-and-dirty history — a too-short narrative that absolutely leaves out a ton of people and details. It’s not the whole story by any measure, and crucially it glosses over the contributions of a large and diverse community that includes a lot of people with disabilities.

Las pautas de accesibilidad antes que las WCAG
The 8 series of website accessibility guidelines is the final set of unified guidelines prepared by the Trace Center. The Web Access Initiative (WAI) of the World-Wide-Web Consortium (W3C) has been launched, and the development of HTML guidelines is being transferred to that body. The Trace Center will be continuing to work with and as a part of the WAI. As a result, the Trace Center will no longer be developing or maintaining this Unified Website Accessibility Guideline series. Readers are referred to the W3C site (http://www.w3.org/wai) for the latest version of the guidelines.
