A Study on Improving User Input based on Pressure Sensitivity of Smartphone
Junho Ko, Yoon Sang Kim · 2013
This paper introduces a pressure-sensitive text input system that provides an easier and faster method for entering Hangeul 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 Hangeul input experiments are conducted on mobile phones from two largest manufacturers in Korea (Samsung and LG). Whereas conventional Hangeul input methods used in Samsung and LG mobile phones require multiple touches for entering characters such as double consonants and diphthongs, the pressuresensitive text input method allows the user to enter them with a single touch.
