Consejos para mejorar la accesibilidad para las personas con discapacidad cognitiva

En  Designing for cognitive accessibility: Where to begin se ofrecen interesantes consejos para mejorar la accesibilidad para las personas con discapacidad cognitiva: There are many techniques that can be used to enhance attention, including: Pausable website carousels – these are multiple pieces of content which rotate across a single coveted space on a webpage. Carousels that are automatically moving content need the ability to be stopped once a particular image captures a visitor’s attention. Restart capabilities – they allow users to save their data and their place in forms and multi-step transactions, like ecommerce. This makes it easier for sites to regain customers’ attention in the event of a distraction. Retracing capabilities – this is a “go back” option which enables site visitors to easily return to recognizable points in their transaction or journey, so they can seamlessly pick up where they left off before becoming distracted.

Las cinco reglas de ARIA

En Using ARIA : First Rule of ARIA: If you can use a native HTML element 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. Second Rule of ARIA Use: Do not change native semantics, unless you really have to. Third Rule of ARIA Use: All interactive ARIA controls must be usable with the keyboard. Fourth Rule of ARIA Use: Do not use role="presentation" or aria-hidden="true" on a focusable element. Fifth Rule of ARIA Use: All interactive elements must have an accessible name.

Segunda regla de ARIA: no cambie la semántica nativa, a menos que realmente tenga que hacerlo. Tercera re

Una excelente crítica de las capas de accesibilidad (accessibility overlay)

Karl Groves, un experto internacional en accesibilidad web, ha escrito  What would an ethical overlay look like? : Accessibility overlays have existed on the market since at least around 2004. Companies such as Readspeaker offered products that displayed a widget on customers’ websites that were best described as “add-on assistive technologies”. The primary feature offered by such products was the ability to read the page content aloud to a website’s users. The benefit to such a feature would seem obvious to the layperson: If you have problems seeing the page or have problems reading, then a feature that reads the content for you would certainly be a significant improvement.  To people with deep knowledge of the Web and accessibility, the shortcomings of a per-site read-aloud widget are glaring. After all: if a user needs to have the content read-aloud to them on one site, they’ll need it on all websites and all applications they use.  In other words, such software is best deployed on

La importancia de la revisión manual de la accesibilidad web

En  The Importance Of Manual Accessibility Testing se analiza la importancia de realizar revisiones manuales de la accesibilidad web y no confiar ciegamente en las herramientas automáticas: Automation really shines here.
