Someone asked me a Braille related question this morning.
It was hard to answer fully in Twitter so I decided to use the blog instead.
Each letter in Braille is six cells. A is one dot or cell, b is two dots, c is two different dots, d is three dots. I’ll explain this in the table below.
| 1 | 4 |
| 2 | 5 |
| 3 | 6 |
You can see from the above table that dots 1, 2 and 3 are on the left and dots 4, 5 and 6 are on the right.
The letter d for example is made from dots 1, 4 and five as shown below:
| 1 | 4 |
| _ | 5 |
| _ | _ |
| _ | _ |
The _ was used to show a cell that no dot has been punched through.
The space in Braille is simply a blank spot.
| 1 | 4 | _ | _ | 1 | 4 |
| 2 | 5 | _ | _ | 2 | 5 |
| 3 | 6 | _ | _ | 3 | 6 |
Here you see that dots have been punched through all six cells. The space has had no dots punched through.
