Mid-Air Hangeul Input System

Some of the traditional keyboards and their layouts are inadequate when it comes to the usability aspect of various responding devices. Even though users anticipate various interaction experiences, the ordinary mutual interaction method has lagged far behind the expectation of users. Thus, this study proposes the Mid-air Hangeul input system available in a large screen environment which direct contact by applying gesture recognition is difficult. User experiment has been conducted based on ten participants. Even though the typing speed was slower than other studies, this system is easy to use and learn. This study proposes the usability in a limited situation which users are facing from the text input viewpoint and the possibility of flexible combination with other devices.
