How to make your web accessible to blind readers?
By Richard Lane
One of the accessibility issues we sometimes take for granted in education is the visually impaired. When creating blogs one should consider the following to be more user friendly. First the author should provide descriptive captions whenever there is an image on the blog. The author should take great care in providing a well written description to the impaired reader. If done improperly this could become frustrating for the disabled reader. Another design feature includes avoiding “click here” or “more”. Navigating from page to page requires alt text to tell the user where to go. Another helpful hint is to put the blogroll on the right hand side. This will make reading more fluent and not as chopped up. Reading comprehension will be easier for the visually impaired user. The blog author should also consider using flexible font sizes. The visually impaired user can then control the font size and thus make reading more accessible. Also, do not force links to open new windows. If a new window is opened the back button may break the link so one should avoid using target =”new” in the link. If the blog is not done properly then this could disorientate the user when navigating from page to page. According to the American Foundation for the Blind, if you “describe your images, supply informative text for links , put navigation links on the right side, use relative font sizes, and have properly labeled comments”, then the visually impaired will be able to use the blog more effectively.
