Because we are committed to achieving ease of use for all users, we have encountered challenges on real projects that have led us to question the common belief that accessibility benefits all users. Although the user experience goals of accessibility and usability often complement each other, sometimes they are incompatible—the best solution for one user group compromises the needs of another group. This presentation introduces design patterns that specifically address accessibility, and identifies design tradeoffs that suggest the need for alternate views of the user interface.
