Accessibility Is Just Another Language
Although typically we think of accessibility in terms of visual, hearing, dexterity, cognitive disabilities and so on, this concept of disability is very limiting in terms of the need for accessible technology. More than 50 million Americans have some sort of disability, and the numbers are increasing as the population ages. Tens of millions of people in the European Union (EU) and half a million worldwide have a disability. Disability knows no boundaries, languages or borders.
