New usability guidelines: WCAG 2.0
The W3C have recently brought out a new series of guidelines for web accessibility (WCAG 2.0) that we've been digesting here in the office. The most immediate change noticeable is the shift in how accessibility is defined. There are now four principles that all have to be adhered to for conformance, rather than a series of levels you can choose to comply with or not. The levels are whether your website is:
- Perceivable - Information and user interface components must be presentable to users in ways they can perceive.
- Operable - User interface components and navigation must be operable. (This means that the interface cannot require interaction that a user cannot perform)
- Understandable - Information and the operation of user interface must be understandable.
- Robust - Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
Although there are several improvements, the language is still very jargony, and an attempt to simplify some of the terms has actually resulted in making some areas more vague.
