Korean vowels have special feature such that same vowels do not appear sequentially in a syllable. And two vowels appear with consistent rules. Using this feature, functional key stroke methods are available to Korean computer keyboard. Tapping a key makes diphthong easily. This will be used to Korean computer keyboard design.

In this study, four alternatives for the arrangement of Korean alphabets on computer keyboards are developed and analyzed to find the better design than the KS(Korean Standard) keyboard. Among the developed four modified models MOD 1 to MOD4, we suggest MOD3 as the best design which incorporates the keys usage frequencies and the compatibility of present standard.

이 논문에서는 전자식 전화기를 이용하여 문자를 입력할 수 있는 코드를 제안하였다. 기존의 문자 입력 방식들과 새로이 고안된 입력 방식을 입력 속도, 수용할 수 있는 문자의 수 및 입력시의 모호성 발생 여부를 판단 기준으로 비교하고 시험하여 새로운 방식이 더 우월함을 입증하였다. 이 방식에 기초하여 한글자모, 영문자를 전화기의 문자판에 배치하고, 그 배치가 최적인지를 검증하기 위해 각각의 배치에 대해 여러가지 시험을 실시하여 표준 $4{\times}3$형의 전화기 자판에 최적인 문자 코드 배치를 선택하였다.

본 논문은 현재 한글이 인터넷이나 컴퓨터에서 사용이 어렵고, 자판 구도가 불합리하며, 남북 및 세계 표준이 아직 정해지지 않고 있어 정열방식이 불일치와 내부 처리 코드의 상이한 문제점을 가지고 있어 기존의 한글처리로는 부적합한 것들을 종합적으로 해결하기 위하여 새로운 방식을 모색하고, 미래의 방향을 제시할 목적으로 정음부호(OPA : Ortho Phonic Alphabet)의 코드 제안에 따른 기존 KS C 5601과 KS C 5700과의 코드 변환시 문제점과 OPA 표준화를 위해 이 연구를 수행한다.

Though the spread of the touch screen devices is now revitalized, the Korean input methods in the touch screen devices are mostly the button input methods using keypads. Even though the button input methods are used with a touch screen, they still adopts the existing qwerty keyboard. It means that the existing methods can not be improved. This research suggests that the Korean input method which can be used in the portable terminals and the touch screen devices, for example, a smart phone which has a limited sized screen. It assigns every vowel a process which corresponds with the Korean invention theory and the vowel input method is to drag it. Through the mock experiments, we confirmed that the simplification of the Korean alphabet is more efficient than the existing methods, in the point of the speed of the Korean input.

Eye-typing is one kind of human-computer interactive input system which is implemented by location data of gaze. It is widely used as an input system for paralytics because it does not require physical motions other than the eye movement. However, eye-typing interface based on Korean character has not been suggested yet. Thus, this research aims to implement the eye-typing interface optimized for Korean. To begin with, design objectives were established based on the features of eye-typing: significant noise and Midas touch problem. Multilevel input system was introduced to deal with noise, and an area free from input button was applied to solve Midas touch problem. Then, two types of eye-typing interfaces were suggested on phonological consideration of Korean where each syllable is generated from combination of several phonemes. Named as consonant-vowel integrated interface and separated interface, the two interfaces are designed to input Korean in phases through grouped phonemes. Finally, evaluation procedures composed of comparative experiments against the conventional Double-Korean keyboard interface, and analysis on flow of gaze were conducted. As a result, newly designed interfaces showed potential to be applied as practical tools for eye-typing.

Researches of Hangul automation have been focused mainly on the set of character system. But, practical problem of using the Korean standard keyboard system of two sets is increment of errors and fatigue due to frequent use of shift keys. The author formulate a hypothesis as follows to solve the problem. 'Changing location and design of shift keys can reduce errors in typing Korean by avoiding interferences with other keys when pressing shift keys.' This study verify the hypothesis by the analysis of experiments using improved keyboard prototypes which have changed layout and design of shift keys. On the result, change of shift key location causes confusion to experienced user. But, while keeping its location, removing other keys at the bottom row and magnifying size of shift keys decrease errors in typing by avoiding interferences. And, the efficiency of typing in Korean is increased, too, because there is not any influence on typing speed. This study focuses on layout and design of shift keys only, but further study for entire layout of keyboard including alternative location of other function keys is needed to improve general usability.

The required minimum size of character diode matrix of Korean letters is estimated from the topological complexity of letter structure. The OR aombination of three letter boards (diode matrice) gives all possible Hangout whole letters in proper traditional combined form with minimum required discernibility. Two forms of first consonants (centre located ones for horizontal vowels and leftward displaced ones for vertical and composed vowels) are switched by only 1 bit of the vowel code. The vowel pattern length is modified by again the last four bits of the code. A new 15bit sized inner code is proposed which permits considerably small sized decoding mechanism.

The aim of this paper is to present a phonetically oriented keyboard array for the International Korean Phonetic Alphabet (IKPA). IKPA is a phonetic alphabet devised on the basis of Hangout (Korean alphabet) (Lee, 1999). Every computer has a keyboard as its input device and the English keyboard array is hewn as 'QWERTY' system, which represents the first six letters of the second line of the keyboard. This array is a traditional one devised to protect the congestion of the keys of the mechanical typewriter. To improve the anay of the keyboard, another system named 'Dvorak' has been devised. Likewise, a serious attempt has been made by the authors to work out an efficient keyboard for IKPA representing the manner of vowel and consonant classification. In the phonetic keyboard, the consonant symbols are arranged in the left hand side according to the Place and mauler of the articulation and the vowel symbols in the right hand side according to the vowel quadrilateral.

본 논문에서는, 한국어 활용에 있어 중의성을 해소해 주고 심미적 효과를 줄 수 있는 개념인 띄어쓰기를, 교정이 아닌 입력 보조의 관점에서 접근한다. 사람들에게 자판을 통한 텍스트 입력이 언어활동의 보편적인 수단이 되면서 가독성을 포기하고서라도 편의를 택하는 경우가 증가하게 되었는데, 본 연구에서는 그러한 문장들의 전달력을 높여 줄 수 있는 자동 띄어쓰기 및 그 활용 방안을 제시한다. 전체 시스템은 dense word embedding과 딥 러닝 아키텍쳐를 활용하여 훈련되었으며, 사용된 코퍼스는 비표준어 및 비정형을 포함하는 대화체 문장으로 구성되어 user-generate된 대화형 문장 입력의 처리에 적합하다.
