I have started developing a simple script and tried how to play sounds with python. I found MPG123, an open source alternative that plays sounds trough the terminal. One of the available alternatives is to use the Subprocess library and the function Popen to run it from Python. I pretend to use for Prototype A arcade buttons, specially those alike to Sanwa buttons. They arrived in 3 weeks, in the meantime I will use the following setup, simulating the buttons. So, I need to be able to identify every time when the user type a character on the Keyboard. And I found, after some iterations, the excellent library py-getch, which can be download with pip ($pip install py-getch).
In the meantime there is no Raspberry Pi prototype, this will be the configuration of the keyboard.
I'm going to save all the data on JSON files, which are directly human-legible with a simple text editor.
On the other hand, the structure of the menu will follow the structure of the chart. Before some one could learn new words, one needs to learn the alphabet in order to keep going. But how are going to be processed the words and characters after learned?

Prototype A is inspired in the setup of the braille Keyboards.
The Braille Matrix is represented by 6 Dots. Those dots are projected under 6 different buttons. Additionally are 3 more buttons, one for spacing/confirmation and two for the devices navigation. Generating a Prototype with the same setup of a braille Keyboard, allow the person to learn how to write the word as well as to memorize using a multiple selection option.
