I worked this gentleman with who is living with a condition where his muscles weakens significantly. He is in bed most of the time, he could move his hands to type letter by letter, but he cannot speak. The solution was to use a text to speech device; which would read whatever he is typing to whoever is listening. He also needs the device to be angled such that he could access and see the keyboard.
I made a foldable stand that would allow him to use the device in bed. The stand is held together by hinges and fold flat when not in use. The device is angled at 60 degrees. There is an anti-tipper on it as well.
