Now a range of software is available that can help to make using a computer an easier, more enjoyable and more productive experience for blind or visually impaired users.
A screen reader is an essential piece of software for a blind or visually impaired person. Simply put, a screen reader transmits whatever text is displayed on the computer screen into a form that a visually impaired user can process (usually tactile, auditory or a combination of both). While the most basic screen readers will not help blind users navigate a computer, those with additional features can give people with visual impairment much more independence. Whilst most screen readers work by having a synthetic voice that reads text aloud, others can also communicate data via a refreshable braille display. But while screen-reading software can be affordable, such hardware is usually very expensive. Free Software Makes ‘Universal’ Access a Reality. Many people could not afford the expensive price tag associated with some of the more sophisticated screen readers. Luckily for them, there are several screen reading software that are completely free. There are about ten free screen readers for all operating systems.
