i just only know that each 2*3 matrix is a character, and i guess the sentence is sth. like "The answer is blah blah .." and at last it takes me a long time to work out the answer ..

Is there any rule to solve this problem?

i'm not a english speaker, hope you understand what i was talking about...

This is Braille, a character encoding for blind people. They 'read' a 3D representation
of these characters with their fingers. Read again the title of this challenge and you'll
understand the hint.

damn this one was hard for me
i tryed everything but Braille

yeah this one needs to be done manually. there's braille alphabets on the internet.

i guess i will have to start writing a program dat translates braille letters to their equivalent and vice versal(the ones i have seen only translate letters to braille). Although solving dis one was piece of cake, cos once i saw the symbols i understood and recognised immediatly wat to do. Luckily it was a 1st grade braille. Nice challenge.

I got the hint in "the lightest touch" and found a translater at this website:

as I see the word "touch", I think about the blind people. Immediately I google "alphabetic for blind people" and I solved it. Sorry, I am not a english speaker.
