WYSIWYG editor spec – interface accessibility

Interface example of a JavaScript based editor.The accessibility of the interface is just as important as the accessibility of the code the editor outputs. The key aspects to focus on are the ‘perceptability’ of controls (e.g. alt text) and ease of using a keyboard only.

Reporting on accessibility issues

After releasing another website accessibility survey (this one global in nature), the topic of ‘reporting’ on accessibility issues has come up again. Frankly I don’t think there’s a right answer, but if anyone can think of a better method, I’m all ears.

Why does google use CAPTCHA?

Recently I noticed that Google will be supporting audio as well as visual CAPTCHA tests. This is so that those who can’t see the screen can listen to a sound clip and fill in a code to prove they are human. Given the more effective alternatives, why is Google taking this approach?

WYSIWYG editor spec – Tables

Interface example of a JavaScript based editor. Each of the editors I’ve been looking at allows the addition of tables, but none of them allow the easy insertion & manipulation of a data table, i.e. one with headings.

Internet Apps Roadmap – Questions

The Roadmap for Accessible Rich Internet Applications (ARIA) outlines the technologies to map controls, AJAX live regions, and events to accessibility APIs, including custom controls used for Rich Internet Applications. This post just draws attention to things I (and Iperhaps other people) could do with some further explanation on.

Image replacement and Voiceover

Freeverses top navigation with no style, showing a standard list. There was a question on the Voiceover list recently about links just being read out as ‘link’ on a particular site: freeverse. It turned out to be due to an image replacement technique.
