Abstract: This paper introduces a pressure-sensitive text input system that provides an easier and faster method for entering Korean in the rapidly expanding smartphone environment. In order to evaluate the effectiveness of the proposed system, a pressure-sensitive text input system is implemented and three Korean input experiments are conducted on mobile phones from the two largest manufacturers in South Korea (Samsung and LG). Whereas conventional Korean input methods used in Samsung and LG mobile phones require multiple touches for entering characters such as double consonants and diphthongs, the pressure-sensitive text input method allows the user to enter them with a single touch. Experimental results confirm that the proposed pressure-sensitive Korean input method was effective in reducing the number of touches required for entering consonants for Samsung's text input method (47% reduction) and for entering vowels for LG's text input method (20% reduction).
