Usability testing often focuses on evaluating the usability of a website for a typical user. However, nearly 20% of the population has a disability, and the number of elderly website users is steadily increasing. Comprehensive usability testing must also consider the needs of people with disabilities.

Accessibility is a benchmark of the quality of our users’ experiences. The two are quite different by definition, but in practice, they’re still separate issues. Accessibility means that your audience can get to the content and message you want them to receive. It’s more than just user experience. Without accessibility, the user experience—good or bad—can’t even happen. So, as the saying goes, “usability depends on accessibility.”

May 9 was the date that Joe and I randomly chose when we first launched GAAD, and we marked the event on that date in 2012 and 2013. When we were advised this date conflicted with some local holidays, this year, we moved it to May 15. After further discussion, and to try simplifying things, Joe and I have decided that rather than a specific date, starting in 2015, we invite you to join us in marking Global Accessibility Awareness Day on the third Thursday of May. This means that the next GAAD will fall on Thursday May 21, 2015.

画像でアイコンを提供する場合は、多くの場合alt属性を利用して、代替手段を提供することが多いかと思いますが、アイコンフォントを利用する場合は提供されるHTMLのサンプルでは十分に代替手段が提供されていないことが多くあります。

例えば、通常使うような文字にアイコン形状が割り当てられているケースでは、アイコンは "t" の一文字のみで表現されますので、Twitterであることの認知が出来ないどころか、ノイズにもなりかねません。
