i am helping a friend who is blind. He is an intellectually vibrant person who became suddenly blind. He wants to preserve as much intellectual curiosity and research ability as possible. Can he start his computer and navegate with voice? How much can he do with only voice? although he could probably handle the keyboard by touch typing.Can he search and then choose screen content with voice? Can all screen content be audible for him, that is, word documents, excel spreadsheets, pdfs etc.? Can he write, send and receive emails? Thanks for your help with this. If you know of another thread or another place to get this info, I would appreciate it.
