               5 years ago, whenever a blind person           revolutionising computer access for the blind
               wanted to use a computer, they would need      regardless of race and geographical location.

          at their disposal. The screen reader market is      screen reader and that a free solution would not
          governed by western ideologies and technologies     be able to stand the test of time. Nevertheless,
          which cater for their own native languages.         NVDA successfully overcame all uncertainties and

          rural India or Morocco would have no opportunity
          to read books in their local language. It is a great
          relief that the cost, portability and localisation
          issues mentioned above are slowly fading away,
          thanks to the emerging mainstream free assistive
          technology solutions accorded by large Information
          Technology companies. However, before all of
          these developments took place, there were two
          blind visionaries from Australia that pioneered the
          screen reader technology for the blind.

            Michael Curran and Jamie Teh are the lead
          developers and founders of Nonvisual Desktop
          Access (NVDA), a free and open source portable
          screen reader that interprets information using
          synthetic speech and/or Braille. They started the
          project with the understanding that blind persons
          who are mostly unemployed or underemployed
          face frustration when they need to incur thousands
          of dollars just to use a computer. However, these
          costs are intelligible and non-existent for those
          with sight.
            Realising the power of open source and free
          solution that may democratize ideas and lead to
          multitude of opportunities, they devised codes        Michael Curran and Jamie Teh,  the lead developers and
          to enable NVDA to verbalise texts on screen. In       founders of Nonvisual Desktop Access (NVDA) (Image
