Hello Siju Samuel,
There is a class of programs called "screen readers." These programs attempt
to read screens. In an ideal world they would be able to read all screens,
but in this area even more than most others we are far from an ideal world.
If your program uses reasonably standard controls with reasonably standard
user interactions there's a good chance one or more existing screen readers
might be able to use it with little or no effort on your part.
In trying to get information about this stuff you may run into parochialism.
Linux users don't like Windows. Window Eyes users don't like Jaws.
There are open source programs available on both Windows and Linux. BRLTTY
is the main, but not the only, Linux braille program. NVDA (Non Visual
Desktop Access) is open source access for Windows though I think there's at
least one other though I could be wrong. Windows also has several commercial
screen readers. All of these deal with the question, how will people get to
your program in the first place. Rather than adding a bit of accessibility
to your program it might be more efficient to see whether existing screen
readers can already deal with it or whether the screen readers' developers
might be willing to make any needed changes.
Good luck,
