For a little over a year now I have not been able to speak. I typically use an eye gaze device, however there are many times for whatever reason that I am unable to use this device. When that happens, I play the alphabet game to communicate. It is a very simple way to communicate. We have a small white board on my chair. It has this table taped on it.
So this is how it works. The entire alphabet is divided into subsections by the vowels. When we get to the set of letters that I want, I blink. Then we go through the subsections letters until I blink at the letter that I want. We then write that down on a white board I keep near my chair and repeat the process.
