The first tactile encoding of hangul was developed by Rosetta Sherwood Hall in 1894.

The initial and final variants have the same shapes, but are shifted across the braille block.

There are two patterns: The consonants that span the width of the block are shifted one space downward when final.

The sibilants ㅅ ㅈ ㅊ all have a bottom dot, while the other aspirated consonants, ㅋ ㅌ ㅍ ㅎ, all have angled forms.

Because the consonants are specifically syllable-initial or syllable-final, a syllable that begins with a vowel causes no confusion when written without ieung.

The w in wa, wo is indicated by making the left side of the block solid (essentially a conflation of o and a for wa, and of u and eo for wo), while the i in ui, oe is shown by making the right side solid.
