Braille

braille positions

Braille is one of the most important codes in the world - it is used by blind people to read and write.

It is easy: there are six dot positions, and the dots are raised up (so you can feel them) in special patterns.

Each pattern of dots is a "character" (a letter or number, etc)

The Braille Alphabet

These are the dot patterns for the 26 letters of the alphabet:
 
braille a to j
braille k to t
braille u to z

 

Notice that k to t are like a to j, just with an extra dot in the lower left corner.

Also, if you took out w, then u to z is like a to e but with two extra dots ... the original code didn't include w!

Numbers

braille numbers 1 to 0

The patterns for the numbers are exactly the same as for the letters a to j. So there is this special character to put in front of numbers: braille num

Example: 3.1416

braille num 3.1416
Without the "num" character it looks like "c.adaf"
(Also note the special character for the decimal point)

Punctuation

Capital Letters

braille capital Capital Letters are shown by putting this special character in front of them

Example: Hi Dad!

braille Hi Dad!

 

Practice

Our examples have all shown the braille character with its matching letter or number, but that is not normally done.
