Is web accessibility an issue for many web users?
Yes. In the sense that it includes usability, it affects us all! With regard to the special needs of disabled groups, it is worth noting that because of the pervasive use of the Internet, their numbers are very large for example, of Europes 387m Internet users, 39m are estimated to have special web accessibility requirements. Web accessibility is often construed narrowly in terms of familiar and obvious disabilities such as blindness, but it also covers such issues as the need to provide clear documents for sighted but colour-blind users and those with limited literacy. Increasing life expectancy is another important factor, as many users are likely to acquire some form of sensory, motor or cognitive deficit as they get older.
