Modern Tools and Technologies for the Visually Impaired

Today, people all over the globe are reaping the fruits of modern technology. One can now use a hoard of devices, ranging from desktop PCs (personal computers) to handy palmtops, for accessing information in one's day-to-day life. But, unfortunately the visually impaired have hardly gained anything form such a mammoth information revolution. Over the past few decades their only means of availing information was through embossed Braille books and audio books. Braille books relating to any particular subject are almost impossible to find, and in most cases they do not even exist. On the other hand Audio books were typically stored on magnetic tapes, and this did not facilitate navigation to different portions of the text.
