My dad PD11 yrs. age 80, has lost his ability to speak. The result is that little by little we are losing "contact" with him. We are considering buying a small ( size of a book) hand held device which he can type out thoughts and comments. The screen is on both sides so that the PWP can read what he is writing and the person opposite him can see it on their side. It is called a Light Writer SL5 and costs $1,100 which Medicare does not cover because it is a communication device. Is anyone out there familiar with such a tool? Would welcome any comments. Marcia
