The Science Behind 16 Keys

Discover how King Sejong's 600-year-old wisdom meets modern technology

Why 16 Keys?

Traditional keyboards require memorizing 26+ keys with complex layouts. HaruHangeul simplifies this to just 16 scientifically designed keys.

King Sejong's Logic

In 1443, King Sejong the Great created Hangul with a revolutionary principle: represent sounds scientifically using basic shapes that mimic the mouth and tongue positions.

HaruHangeul follows this exact same logic. By understanding the scientific relationship between consonants and vowels, we reduced complexity while maintaining complete functionality.

Consonant Formation Principle

ㄱ
→
ㅋ
→
ㄲ

Same base shape, different aspirations

Syllable Formation

ㄱ
+
ㅏ
=
가

Consonant + Vowel = Syllable

The Building Blocks of Hangul
