Cinco mitos sobre la accesibilidad digital desmentidos

En 5 Digital Accessibility Myths Busted se explican estos mitos:
  • Myth #1: Only a small percentage of my users need an accessible website or app
  • Myth #2: It will take too much time/effort/money to make our website or app accessible
  • Myth #3: Digital accessibility is a one-time-only task for the developers
  • Myth #4: Accessible websites and apps are plain or ugly
  • Myth #5: I used some automated testing tools, so my website or app is now accessible

Muy interesante este gráfico:

Examples of these communities include:

  • Aging population—may need captioning on videos or larger font sizes to read the text
  • Users whose native or primary language is not English—may need more time to read text on auto-rotating slideshows
  • Users with cognitive limitations—may need accessibility-friendly fonts or bulleted content to help focus
  • Users with limited or low vision—may need to zoom in on content to be able to read and understand it
  • Users with situational disabilities—may need better color contrast so glare on a screen does not interfere with them reading the content
  • Users with temporary disabilities—may need to access everything with only their keyboard because they are unable to use a mouse

Cómo las Google Glasses iban a ayudar a las personas con discapacidad

Ya casi nadie habla de las Google Glasses, es más, ya casi nadie las recuerdas. Pero hubo una vez que existieron: aparecieron y pareció que todo iba a girar alrededor de las Google Glasses.

Algunos artículos sobre cómo las Googles Glasses iban a mejorar la vida de las personas con discapacidad:

Mobile Lorm Glove para personas sordociegas

Muy interesante el Mobile Lorm Glove:
The Mobile Lorm Glove is a mobile communication and translation device for deafblind persons. The glove translates the hand-touch alphabet “Lorm”, a common form of communication used by people with both hearing and sight impairment, into text and vice versa.
Textile pressure sensors located on the palm of the glove enable the deafblind user to “lorm” onto his or her own hand to compose text messages. A Bluetooth connection transmits the data from the glove to the user’s handheld device. It is then automatically forwarded to the receiver’s handheld device in the form of an SMS. If the wearer of the Mobile Lorm Glove receives a text message, the message will be forwarded via Bluetooth from his/her handheld device to the glove. Initiated by small vibration motors located on the back of the glove, tactile feedback patterns allow the wearer to perceive incoming messages.
The Mobile Lorm Glove provides particularly two innovative ways of communication for deafblind people. It supports mobile communication over distance, e.g.  text message, chat or e-mail, and it enables parallel one-to-many communication, which is especially helpful in school and other learning contexts. With this newly developed technology and interaction, it will soon become possible to also „feel” E-Books or Audiobooks. The Mobile Lorm Glove functions as a simultaneous translator and makes communicating with others without knowledge of “Lorm” possible. As a result, it empowers deafblind people to engage with a wider social world and further enhances their independence.
The next step of our research will be to prepare the implementation of direct speech input and output.

Nuevo estándar de accesibilidad web en China

Last August the Chinese Standardization Administration issued a new national standard, GB/T 37668-2019, “Information Technology Requirements and Testing Methods for Accessibility of Web Content“. According to the China Disabled Persons’ Federation (CDPF) , this standard will be implemented as a recommended standard in March 2020, and will promote technical and policy support for information accessibility development in China. 
The standard was jointly developed by a number of organizations, led by CDPF and Zhejiang University. It references the World Wide Web Consortium’s Web Content Accessibility Guidelines (WCAG) 2.0 and 2.1. W3C congratulates the standard on the closer harmonization with international standards, which we believe can benefit many communities in China.
En China Focus: China introduces new standard to assist visually impaired internet users podemos leer:
China on Sunday launched a new national standard for the development of barrier-free services on the internet, aiming to better serve the visually impaired population in the country. 
33-year-old Zhao Cheng is among the 17.32 million visually impaired people in China. After he lost his eyesight 10 years ago in an accident, Zhao had to get used to living in darkness. But with the latest technology, he is able to send voice messages to his friends and listen to their replies through WeChat. 
Over the past few years, more and more internet companies have started to step into barrier-free services for the disabled. According to incomplete statistics, by the end of 2019, more than 40 internet companies had set up departments in charge of barrier-free services in China. 
Internet giants in China including Alibaba, Baidu, Tencent and iFLYTEK have all invested in research and development in the field of barrier-free access to information during the last decade, with successful products being put into use in special education schools and even performing art troupes for the disabled.

Los problemas que tienen los "accessibility overlays"

Una "web accessibility overlay" es la capa que se añade a un sitio web mediante un software que promete mejorar la accesibilidad de los sitios web. Ejemplos de este software son Inclusite o inSuit.

En Web Accessibility Overlays Do Not Work se explican algunos de los problemas que tienen este tipo de soluciones.

En Not All Accessibility Overlays Are Created Equal se clasifica este tipo de software en dos tipos:
There are two types of overlays: targeted “Custom JavaScript overlays” – customized to the specific page and website, these overlays can make comprehensive changes to any accessibility concern on a specific page, and “Tool-based overlays” often seen in the form of a toolbar, plugin or extension – these make limited, generic changes to the page, some of which can be controlled by the site visitor.
Y explica los siguientes problemas que tienen las "tool-based overlay solutions":

  • They require people with disabilities to download and use a different tool they aren’t used to, instead of the assistive technology they are comfortable with.
  • They require the user to know about and install a custom plugin that might introduce its own accessibility problems.
  • They don’t work for native mobile applications, so your website is still at risk for an accessibility-related complaint or lawsuit.
  • They only address a limited scope of accessibility issues:
    • They provide simple modifications to the page overall, they may change the color contrast, add a focus indicator or add a high contrast mode which addresses only a small number of the possible accessibility barriers.
    • They cannot add missing complex keyboard or device interactions, they cannot fix specific site semantics and they cannot add meaning or text alternatives where these are missing.

Los placeholders causan problemas

El uso de los placeholders causa muchos problemas, no solo de accesibilidad, también de usabilidad. En Placeholders are problematic, se explican muchos de los problemas:
Since the placeholder attribute came along, lots of us started using it as way to show form field hints. Their appeal lies in their minimal aesthetic and that they save space. 
Some go a step further replacing labels with placeholders. Either way, placeholders are an inclusive design anti-pattern.

Publicada una nueva edición de WebAIM Million

Hace unos días se publicó una nueva versión de WebAIM Million. Parece que se va a convertir en un estudio anual.

La introducción del estudio dice:
In February 2019 and February 2020, WebAIM conducted an accessibility evaluation of the home pages for the top 1,000,000 web sites and over 100,000 additional interior site pages. The evaluation was conducted using the WAVE stand-alone API (with additional tools to collect site technology parameters). While this research focuses only on automatically detectable issues, the results paint a rather dismal picture of the current state of web accessibility for individuals with disabilities.
Los resultados del estudio son muy interesantes.

¿Cómo vive el confinamiento por el coronavirus una persona sordociega?

Muy interesante el artículo ¿Cómo vive el confinamiento por el coronavirus una persona sordociega?. Sobre el uso de la tecnología se comenta:
En su caso, confiesa que lo tiene "fácil" a la hora de comunicarse con familiares o amigos a distancia, ya que asegura que lleva "muchos años tirando de las tecnologías como un sistema alternativo de comunicación". "Prueba de ello es que nunca antes había teletrabajado y de la noche a la mañana me encontraba trabajando desde mi casa con normalidad, comunicándome con mis compañeros de trabajo a través del ordenador con la ayuda de una línea braille (un dispositivo que lee en braille todo lo que aparece en la pantalla del ordenador)", explica.
Si bien admite que también ha explorado otras vías de comunicación. "El otro día estuve probando Skype con mi pareja. Yo me enfoqué con el móvil, de forma que ella me pudiera ver y oír, y al mismo tiempo conecté mi línea braille al móvil y abrí el chat para ir leyendo en braille lo que ella me decía", relata. "Quién lo iba a decir, yo, sordociego y haciendo una videollamada", celebra.
