Hangeul can be used in writing various languages around the world. For such reason, many regions of the world are considering the use of Hangeul, following the trend of the ‘Korean Wave.’ Accordingly, many researchers are studying methods to use Hangeul to write various languages and spread Hangeul around the world. Considering how to globalize the use of Hangeul and turn it into an international language, this paper suggests a three‐set type Hangeul keyboard for international use. In today’s mobile environment with smart‐phone devices, Hangeul is an excellent bridge that can connect various languages, as well as an optimal character which people lacking their own alphabet can easily use. The one‐hand keyboard suggested in this paper aims to be not only more scientific, but also more convenient for the users compared to previous inputting methods. It is also purposed to input various languages without much difficulties. In short, the goal of this paper is to present a one‐hand Hangeul keyboard that can be used to conveniently input various languages around the world. This paper leaves the study regarding the methods of writing the consonants/vowels of Hangeul to related experts, and focuses on finding an effective way of inputting character through a one‐hand Hangeul keyboard using previous consonants/vowels. In addition, regarding the standardization of a one‐hand inputting method which is still under discussion, this paper tries to suggest an alternative which considers the true meaning of a proper standardization.

본 논문은 지체장애인들의 컴퓨터 접근성을 향상시키기 위해서 Head Pointing System을 기반으로한 키보드 대체 방법을 제안한다. 먼저 컴퓨터의 접근성을 돕기위해 현재 사용되고있는 Head Pointing System에는 어떤 기능을 대체하고 있는지 간략하게 살펴보고, 본 논문에서 제안하는 방법이 이전에 사용되었던 Head Pointing System, On-Screen Keyboard를 함께 사용하여 문자를 입력하는 방식에 비해 어떤 이점이 있는 확인한다. 또한, Quikwriting 방식을 사용하여 사용자에게 단순하고 직관적인 제스쳐를 요구하도록하여 입력에 대한 부담을 낮추고, 사용자 개인의 제스쳐 특성에 따라 문자를 입력할 수 있도록 하기위해 신경망 알고리즘을 사용하였고 이를통해 Head Pointing System기반 문자입력 방법이 유용함을 확인할 수 있었다.

본 연구는 표준형 키보드를 사용하는 뇌성마비 아동 13명과 미사용 뇌성마비 아동 11명을 대상으로 자체 제작한 천지인 방식 대체 키보드의 문자입력 속도와 정확도를 알아보았고, 3주 동안의 대체 키보드 사용훈련 후 표준형 키보드와 비교하여 입력효율성과 학습용이성이 어떠한지도 알아보았다. 연구 결과, 개발한 천지인 방식 대체 키보드는 뇌성마비 아동이 일정 기간 사용훈련을 거치면 문자입력 속도 및 정확도가 크게 향상되고, 표준형 키보드와 비교해도 입력효율성이 뒤지지 않음을 알 수 있었다. 또한 표준형 키보드 사용자와 미사용자의 대체 키보드 사용훈련 전후 문자입력 속도 및 정확도 향상 정도가 유사하여 학습용이성 측면에서도 초보자와 기존 사용자 모두에게 사용 적합한 것으로 나타났다.

The purpose of this study was to evaluate text entry speed and accuracy using the alternative keyboard based on Chonjiin input method. In addition, this study was carried out to compare the alternative keyboard with standard keyboard on input efficiency and learnability after 3 weeks training of alternative keyboard. The group of subjects consisted of 13 children with cerebral palsy who used a standard QWERTY keyboard and 11 children with cerebral palsy who didn’t use a standard QWERTY keyboard. In this study applied the paired t-test and independent t-test to determine the statistical significance of results at .05 level of significance. The results of this study were as follows:1. The text entry speed significantly increased in 24 children with cerebral palsy after 3 weeks training of alternative keyboard(p<.05). 2. The text entry accuracy significantly increased in 24 children with cerebral palsy after 3 weeks training of alternative keyboard(p<.05). 3. In 13 children with cerebral palsy who used a standard QWERTY keyboard, there were not statistically significant difference between standard and alternative keyboard in text entry speed after 3 weeks training of alternative keyboard. 4. In 13 children with cerebral palsy who used a standard QWERTY keyboard, there were not statistically significant difference between standard and alternative keyboard in text entry accuracy after 3 weeks training of alternative keyboard. 5. In using and non-using children with cerebral palsy of standard QWERTY keyboard, there were not statistically significant difference in increasing rate of text entry speed after 3 weeks training of alternative keyboard. 6. In using and non-using children with cerebral palsy of standard QWERTY keyboard, there were not statistically significant difference in increasing rate of text entry accuracy after 3 weeks training of alternative keyboard. These result suggest that the alternative keyboard based on Chonjiin input method is good for all children with cerebral palsy in efficiency and learnability of text entry.
