Objective: The aim of this study is to determine legible Korean font sizes within in-vehicle information systems(IVISs) in diving conditions. Background: Font legibility within IVISs is one of important causes on its' safe operations during driving. Several researches proposed some guidelines on the legible English font sizes within IVISs. On the contrary, appropriate Korean font sizes have been hardly known in spite of the typological differences between English and Korean. Therefore, more systematic researches for improving the legibility on Korean font size within IVISs have been required. Method: In this study, an experiment was performed with the following experimental factors: the existence of vibration, the color contrasts(white on black, black on white), the font types(HDR, CubeR, Gothic), and the font sizes(6, 8, 10, 12, 14, 16, 18, 20, 22, 24pt). To fit the experimental conditions into real driving environments, the illuminance was controlled to 15lx by using LED lamp and the distance between IVIS and participants was kept to 70cm. Moreover, all participants took the shutter glasses for employing well-known occlusion techniques. Results: The experimental results showed that 'HDR' and 'Non-vibration + Black on white' group took the shortest response time, and decreasing slopes of the response time with increasing font sizes were slowing down at 14pt then flattened out at 22pt regardless of the existence of vibration and color contrasts. Conclusion: The minimum size for legible Korean font would be about 14pt(5.47mm) and the optimum size would be about 22pt(8.59mm). Application: The guideline on the Korean font sizes from this study will be applied to design an IVIS in the future.

The research on the factors which effect on legibility is mainly utilized as the basic data of selecting the standard guideline of VDT screen. But the research on Korean is scarcer than that of English. Furthermore, it is unreasonable to apply the results of the foreign language to Korean, beause of the difference between the typography of English and that of Korean. Therefore, more systematic and ergonomic research of the Korean typography on VDT screen is needed. In this paper, an experimental study on search speed and error rate is designed and performed according to different Korean letter size and font on search task with VDT. The experimental screen based on popular Ming and Gothic style is made up of total 12 artificial screens, each 6 different font size. As the criteria of the performance, searching speed(s.s.) and error rate (e) are selected, and CFF value is measured to evaluate user's visual fatigue. The results of experiment in font show that the Korean Gothic style is superior to the Korean Ming style in user's visual performance. The letter size that gives user the optimal performance ranges from the visual angle 39.8' to 55.5' in Ming style, from the visual angle 39.8' to 52.6' in Gothic systle. In visual fatigue experiment, the better performance of letter size is, the less tired user feels. And the smaller letter size is, the more tired user feels. There is no relationship between font and user's visual fatigue.

한글의 자소들은 몇 가지의 획으로 구성되어 있고, 완전한 글자들은 자소들의 조합으로 구성되어 있다. 획과 자소들을 조합하는 과정에서 그 구성들의 크기나 위치가 변화할 수 있으므로 폰트를 제작하는데 많은 노력이 필요하다. 이와 달리 METAFONT는 매개변수 값을 변경하면서 획과 자소의 크기와 위치를 쉽게 변환할 수 있는 시스템을 제공하여 폰트 제작 과정에 효율성을 높일 수 있다. 본 논문은 METAFONT를 기반으로 사용자가 매개변수를 수정하여 다양한 폰트를 자동으로 생성할 수 있는 구조적 한글 폰트 생성기를 제안한다. 본 논문에서 제안한 한글 폰트 생성기는 폰트 임베딩 분야와 폰트 편집기 분야에 적용할 수 있다.

본 연구에서는 휴대용 정보 단말기(Personal Digital Assistant : PDA)의 정보 표시부에 표시되는 문자정보를 읽을 때, 문자의 크기가 사용자의 인지적 스트레스에 미치는 영향을 조사하였다. 평가는 주관적 평가법(주관평가)과 생리적 평가법(뇌파측정)을 행하여 결과를 도출하였으며, 분석 및 고찰은 문자정보를 읽을 때 나타나는 사용자의 인지적 스트레스와 문자크기와의 관계성에 주목하였다. 분석의 결과, 다음과 같은 2개의 결론이 얻어졌다. 1) 표시한 문자크기(8point, 10point, 12point, 14point, 16point) 중에서 상대적으로 읽기 쉽고, 인지적 스트레스가 적다고 생각되어지는 문자크기는 14point이며, 상대적으로 읽기 어렵고, 인지적 스트레스가 많다고 생각되어지는 문자크기는 7point로 나타났다 2) 문자정보의 인지에 대한 대뇌피질의 반응은, 뇌의 후두엽과 두정엽의 후두시각연합영역을 활성화시켰다. 또, 문자정보에 대한 시각성 인지는 문자크기가 14point보다 작은 경우에, 대뇌피질의 활성수준을 향상시키는 것으로 나타나, 휴대용 정보기기에 있어서 문자크기가 14point보다 작으면 작을수록 인지적 스트레스에 영향을 미치고 있는 것으로 생각되어진다.

Effectiveness of information conveyance in reading is affected by several factors such as line length, letter size, line spacing arrangement as well as typeface itself. This study examined relative importance of these factors by asking people to read the texts that was constituted with non-square form letter and rank the preference of texts through conjoint analysis. In the case of reading time, justification was the most important factor, followed by leading, line spacing, letter width, line length, font size, font type in their order of importance. And in the case of preference decision, letter width was the most important factor, followed by font size, justification, line spacing, leading, line length, font type. The result will be useful in understanding how to consider human preference in the hangul typography.

This study evaluated the effects of the syllable number(one, two), font type(gothic, myung), color contrast (black on white, white on black), display type(paper, LCD), age(20s, 60s) and character size(2~80pt) on the Korean characters' legibility. Total twenty subjects from two age groups (20s: n=10, 60s: n=10, five male and five female in each group) participated in the legibility test. A target panel was presented in the distance of 50 cm, and subjects conducted a reading tests for, in total, 16 treatment conditions (full combination of syllable number, font type, color contrast and display type). Results showed that two-syllable words revealed better legibility than one-syllable character. The main effects of the age, display type, font type, color contrast, and character size were statistically significant(p<0.01). Paper showed better legibility than LCD, particularly in the 20s and in the character sizes of less than 9pt. Gothic revealed more correct answers than Myung, particularly in the 60s, paper, and white on black conditions. It is expected that these results can provide basic data for the determination of the Korean characters' minimum legible size standards. For example, the minimum legible size for the Gothic and black on white characters presented in the paper should be 5pt for 20s and 1lpt for 60s if the 75% correct reading(3 correct answers in this study) was applied for the legibility criterion.

A design guideline about legible and preferred Korean character sizes is necessary to provide better visual information in a group-view display. The present study examined the legible and preferred Korean character sizes by an experiment employing eight background-font colors and four representative font types (Gulim, Ming, Gothic, and Batang). Forty subjects (male : 20 and female : 20) in their 20s were recruited for the experiment. The legible and preferred sizes were determined based on the method of limits, one of psychological approaches. The results showed that the legible and preferred sizes increased as the contrast between background and font colors decreased. In addition, the legible and preferred sizes for Gulim were significantly smaller than those of the other font types. It is expected that the present study may contribute to providing better visual information in a group view display.

This study examined relative importance of these factors by asking people to read the texts that was constituted with square and non-squre form letter and rank the preference of texts through conjoint analysis. In the case of reading time, font type was the most important factor, followed by leading , line width, font size, line length, justification, letter width in their order of impotance. And in the case of preference decision, font size was the most important factor, followed by font type, leading, line width, letter width, justification, line length. The result will be useful in understanding how to consider human preference in the Hangul typography.
