Open-Captions, Using Closed Captions as Meta Data for ASL

Monday, October 24th, 2011

This post is by guest author Narayanan Ramakrishnan, whose Open-Captions project parses the closed caption track of a YouTube video to provide ASL translations of words. Caption tracks include timestamps and text, parsing this as meta data opens new opportunities for contextually dynamic pages.

Narayanan is a GeorgiaTech graduate and has a passion for creating accessible tech projects. Previous projects include an accessible map of New York City, transliteration of Facebook posts, and visual guide to Indian politics.


What is Open-Captions?

According to research, over 90% of deaf children have hearing parents who “frequently do not have fully effective means of communicating with them”. The American Sign Language (ASL) is a difficult language to learn, especially as a second language.

Open-Captions makes it easy for parents and children to learn and practice American Sign Language together while watching their favorite videos on YouTube. People can find closed captioned videos on any topic with the Open-Captions search engine. The viewer is able to select individual words in the video’s caption stream and see the American Sign Language representation of the word.

Test ARIA and Focus with Bookmarklets

Friday, April 8th, 2011

Sometimes it is difficult to keep track of your keyboard focus, landmark roles and tab index. We’ve created a couple bookmarklets for our own testing. These easy to use bookmarklets add CSS to quickly highlight your page’s information. Simply save the following links to your bookmarks, then load your test page and click the bookmark. While these work in all browsers, you’ll get better results using Firefox, Chrome, Safari, or Internet Explorer 9.

You’ll learn a lot about the Yahoo! home page’s use of ARIA with the landmark/tabindex bookmarklet. Check it out.

Welcome to the Yahoo! Accessibility Lab’s Code Library

Wednesday, February 23rd, 2011

The Yahoo! Accessibility Lab launched Accessibility.Yahoo.Com on the 20th anniversary of the Americans with Disabilities Act in 2010 to give a broad voice to individuals in the disability world. We’ve gathered writers around the world to discuss the experience of disability.

As a technology company, we also felt the need for a technical repository. This new library section provides information on building accessible web pages via code snippets. It also tells you why, what not to do, and even provides audio/visual references to what users can expect.

Our Screen Reader Tests are a good place to start. These articles explain various coding patterns, both good and bad. The articles feature audio recordings of screen readers announcing the samples. You’ll learn even more if you enable a screen reader and listen to the articles.

The majority of articles will focus on specific problems and how to solve them. This includes introducing ARIA to your web site, creating accessible forms, and accessible CSS and JavaScript solutions.

We are also including accessibility presentations the Lab has given. We try to include transcripts if the videos are not captioned.

Please leave your feedback on articles if you have questions or alternate solutions.
