Atix: Language learning audio based device

Yesterday I tested and used the device in my whole travel to University. It was very unpleasant that after every round I need to select from the beginning the option to keep exercising, so I added now the option to select if you want to repeat the session after you completed the 5 words round. It asks you and Left movement with the Joystick is "Yes" and with the right is "No" (everything with audio).

I am want to keep doing only Software changes, to prove if only 1 joystick (with a push button in it) is enough for an Interface.

I want to add:

1. General audio instructions that you can hear every time (How to use it)
2. Categories (Computer science vocabulary English --> German)
3. New algorithm to select the random words to learn
4. Repeat the word in English 

• Generation of menu with:
  • Learn (it isn't ready)
  • Exercise (5 random words)
  • Volume control (from 1 to 30 in the scale of the mp3 decoder)
