Руководство по обеспечению доступности Web-контента (WCAG) 2.0. WAI-ARIA. WAI-ARIA (Web Accessibility Initiative — Accessible Rich Internet Applications) — технологический стандарт, разрабатываемый Консорциумом Всемирной паутины для предоставления возможности полноценного использования Интернета людьми с физическими ограничениями (нарушение работы органов зрения и опорно-двигательного аппарата).
Реализация стандарта WAI-ARIA приносит наибольшую пользу на сайтах с динамическим содержимым, а также на сайтах с развитыми нестандартными элементами управления. The Paciello Group – Your Accessibility Partner (WCAG 2.0/508 audits, VPAT, usability and accessible user experience) This tool provides two useful core functionalities: a pass/fail assessment against WCAG 2.0 color contrast success criteriaa simulation of certain visual conditions, including dichromatic color-blindness and cataracts, to demonstrate how your web content appears to people with less than 20/20 vision The CCA is available for Windows and Mac, and in multiple languages including English, French, Dutch, Italian, German, Hindi, Korean and traditional Chinese.
Note: the visual simulation functionality is only available in the Windows version. Acknowledgements The Colour Contrast Analyser was developed by JUn in collaboration with Steve Faulkner (The Paciello Group, Europe). A prior version of the CCA was partially funded by the Trace Research and Development Center as part of the NIDILRR Funded Rehabilitation Engineering Research Center (H133E030012) Contribute.

Introduction Attention to accessibility usually comes into play in the later phases of product development. Accessibility audits are typically performed during quality assurance and user acceptance testing phases. The best approach to accessible user experience is to integrate accessibility into the design and development process.

The idea of pressing a key to enter text has been around for a long time.
One of the early prototypes of what later became the typewriter was invented in 1808 by Pellegrino Turri for his blind lover so she would be able to write him letters—or so the story goes.

Fast forward to modern times: the keyboard remains a key element in ensuring that people with disabilities are able to communicate and engage in everyday activities. As our communication technologies advance and we become increasingly reliant on websites and apps to facilitate our interpersonal interactions, we must not forget the critical role of the keyboard.

Step back from the screen. Close your eyes slightly so that your vision is a bit clouded by your eyelashes. Can you still see and use the website? The Accessibility Project. Accessibility APIs: A Key To Web Accessibility. Advertisement Web accessibility is about people.
Successful web accessibility is about anticipating the different needs of all sorts of people, understanding your fellow web users and the different ways they consume information, empathizing with them and their sense of what is convenient and what frustratingly unnecessary barriers you could help them to avoid. Armed with this understanding, accessibility becomes a cold, hard technical challenge. A firm grasp of the technology is paramount to making informed decisions about accessible design.
How do assistive technologies present a web application to make it accessible for their users? Reading The Screen To understand the role of an accessibility API in making Web applications accessible, it helps to know a bit about how assistive technologies provide access to applications and how that has evolved over time. A World of Text Getting Graphic Off-Screen Models Recognizing the objects in this off-screen model was done through heuristic analysis.

My Experience Designing for the Blind. My Experience Designing for the Blind Research, Design, and Prototyping At Purdue, there is a program called EPICS in which students can work with real world clients to engineer products to be used in the community at large.
In my Interaction Design class this semester, one of our projects was to work with an EPICS team to provide a IxD perspective to their product. The workflow, from what I have seen in EPICS this semester, is usually get a brief from a client, build a prototype, give it to the client, change the prototype according to their feedback, and repeat until it is good enough.
