I have CRACKED it! I can now type as a blind person by using a Bluetooth keyboard connected to my iPad. I have put bumps onto one or two letters on the keyboard so that I know exactly where to position my fingers. If I type into my app called dream writer, it speaks each word to me after I have typed it, so that I know I have made a mistake.
This is amazing to me. I need to practise a bit but I have finally found a way through. I can hardly believe it. I am away now! I can type my book!
