Coleman Yee blogs about web accessibility (or the lack of) in response to this IDA reply on the level of access for persons with disability at (Singapore) e-govt websites:
What is website accessibility
For those who are not familiar with web accessibility, it’s simply about making a website accessible or usable or “viewable” by different web browsers and devices, and thus accessible by the widest possible audience, including those with disabilities.
For instance, an accessible website would be usable by a screen reader, a special software that reads aloud what’s on the screen and browser, thus enabling a blind person to access that website.
Website accessibility is thus often associated with making a website accessible to users with disabilities, particularly the blind.
Conversely, if a blind user cannot access certain information on a website using a screen reader, that website is considered not accessible.
Web accessibility is also about access by devices like mobile phone browsers, or even browsers other than Internet Explorer like Firefox, Safari, or Opera.
The accessibility of Singapore Government websites
When you surf around Singapore Government websites on a non-Internet Explorer browser, you sometimes encounter a message telling you that you can’t continue unless you’re using Internet Explorer.
That’s not an accessible website.
Whole populations of Singaporeans are being excluded from such online government services simply because they use a Mac instead of a PC, or because they don’t wish to use (the technically inferior) Internet Explorer.
And we’re not even talking about access by small screen devices like mobile phones, or access by disabled users. The situation is far worse for them.
