7.4 Braille Dot Numbering Convention

A standard braille cell consists of six dots arranged in two columns and three rows. Computer braille has introduced a fourth row at the bottom. Each dot can be specifically identified by its number as follows:

1

Row 1 (top) left.

2

Row 2 left.

3

Row 3 left.

4

Row 1 (top) right.

5

Row 2 right.

6

Row 3 right.

7

Row 4 (bottom) left.

8

Row 4 (bottom) right.

Perhaps a picture will make this numbering convention easier to understand.
