I figure that you can have a sighted person do something similar to
what is done for all normal phone keyboards and computer keyboards:
put some sort of adhesive 'bead' or a drop of superglue or anything
that won't rub off easily on the 'center' button. Look at your
cellphone, there should be a raised dot on the 5. Same with the f and
j keys on a keyboard.

This should work rather well I would guess for alignment.
