thanks to my friend Mohammed khawaja for this post about me on his blog:
I am often asked how can I use the computer although i am blind. Often times people will even doubt that it’s doable. The short version of the answer is that I use the computer through a screen reader. which is basically a software that tells the blind user what is displayed on the screen at any given event, through either speech or braille. That event may be a dialogue box, an edit window, a hyber text document, a VB project, etc.
