Direction
DraftFour arrows around a Braille number, plus one LED. Number and colour pick the arrow; the panel may ask several times.
First appears in level 4
How to recognise it
Four arrow buttons (up, down, left, right) around a cluster of dots in the middle, and one LED in red, blue, green or yellow. The dots are a Braille number from 1 to 9 that only the blind player can read: hovering over them makes the game print the number. The deaf player sees the arrows and the LED.
Procedure
Hover over the dots and say the number: "Direction, number four." Wait for one direction, repeat it, press that arrow once. Then say what happened: cleared, changed, or nothing. If the panel changed, read the number again; it is a new state.
Common mistakes
Reusing the last direction after the panel changed. Number and LED are re-read after every press.
Left and right from the wrong point of view. Agree before the round that it is always the blind player's left.
A bare number plus a gesture read as "switch plus direction". Name the module first ("Direction, four").
Solver
Enter what you see on the bomb and get the action for the current state.
