Traditional market is a place filled with traditional culture and sentiments of the local population, so this is not just a commodity trading places that has been at the centre of our life, including culture and the local economy and the people of the community. However, many consumers still ongoing by the facilities that aging is deprived to the department stores and hyper-marts. Also, low awareness of the displayer, including the internal facilities, is very reality is bad development compared to the appearance, in particular product names, price tags and one mark of origin, such as signs, despite Upon entering the market first leaps to the eye are not improved the situation as it is necessary for the improvement of typography for traditional market. Therefore, examine the fonts used in the traditional markets, proceed to further analysis in the future by building a dedicated font made of only the traditional market it has a distinctive identity and unity of the market typography to present the guidelines of the market font.

Television market is rapidly changing into HDTV according to increase in the programs transmitted in HD. However, there is no guideline of Korean typography which is suitable for HD display. Here we provide a guideline on Korean font style, its size and transparency to acquire high readability on HD screen. The readability was assessed with two different criteria: reading speed as an objective index and preference ranking as a subjective index. In the results, the participants tend to prefer and read faster slim fonts on HD display when compared to the bold type commonly used on 3D display To the font size, smaller one was preferred on HDTV than that displayed on SDTV. To the transparency, users revealed strong preference on 40% transparency although it did not affect the reading speed when the contrast between text and background was fixed on 40%. But clearly, preference on 40% transparency.

Recommendations for older driver-friendly automobile interior design have been determined by taking into account older people's physical and cognitive characteristics. Twenty three older people (aged from 54 to 78) and five younger people (from 20 to 29) performed several tasks in actual driving conditions, in which their reaction times and performance errors were recorded. Some design factors were found to be related to older drivers' visibility and controllability. Several design recommendations were proposed in terms of cluster color and font, display location, and HVAC control type. Proposed recommendations are expected to satisfy a wider range of older drivers as these will facilitate automobile interior designs which are fitter to older drivers' visual, cognitive, and manual capabilities.

This paper mainly focuses on the design factors of a website targeted at shopping mall websites in China and Korea. We formulated 15 different hypotheses regarding how those design factors are different. The targeted websites are "Gmarket" in Korea and "Taobao" in China. The selected design factors of a shopping mall website are (1) color and design, (2) photo, graphic, and font size, (3) the clarity of information delivery, (4) website structure, (5) screen balance, (6) product display, (7) product harmony, (8) a form of font and icon, (9) visual atmosphere, (10) differentiated color, (11) interesting words, (12) technical skills, (13) entire visual design and atmosphere, (14) navigation, (15) search function for products or information. As a result of analyzing the result using the SAS 9.2 package tool, we figured out that there was a difference between design factors. Additionally, we analyzed this difference and suggested a strategy to design the effective shopping mall web sites.

본 논문은 실내용 LED 전광판 시스템에서 문자 출력을 위한 완성형 폰트 기법을 개선하기 위해 비트맵 이미지 픽셀의 색상값을 이용하여 실시간으로 폰트를 생성하는 기법을 제안한다. 본 논문에서 제안한 기법은 출력을 위한 문자 폰트를 사전에 정의해 저장하지 않고 텍스트를 비트맵 이미지로 변환한 후 이진화 하여 각 픽셀의 색상값을 이용해 출력 폰트를 실시간으로 생성하도록 한다. 실시간 폰트 생성 기법은 사전에 정의된 문자와 입력된 데이터를 비교하기 위한 과정이 생략되어 메모리 낭비를 줄일 수 있다. 또한 제안된 기법은 사전에 정의되지 않은 다양한 형태의 문자를 입력받아 출력할 수 있기 때문에 문자 표현 방식이 다양해져 정보 전달 효과를 높인다.

In this paper a new OSD (On-Screen Display) development system for digital devices is presented. The proposed system is an example of the ubiquitous systems because it can be used to co-develop an OSD tn any time at any place if the web can be accessed. In UI, OSD is an important pan of digital devices. Especially, OSD implementations for multiple languages are essential to export digital devices and make them user-friendly. The proposed system consists of four components: font editor, menu editor. R/C simulator, and screen editor. It provides all the functions to develop an OSD and the result can be downloaded to a digital device. The proposed system was used to develop an OSD for 31 countries and the lead time of development was reduced from 52.7 days to 20 days.

Web pages with complex layout and small font size do not display well on large screen display such as TV because it has limited capabilities: long distance view, passive user attitude, limited input device like a legacy remote controller. We have designed and implemented new semantic zoom browsing facilities to support effective navigation on Internet-connected digital television with limited capabilities. Our browser performs partitioning of an HTML document content into semantic blocks. Semantic blocks present summarized information with more readable style and modified layout for optimal reading and browsing. Individual blocks can be selected by the user and zoomed in more detail information by the user. The scrolling on large display device needs more user interaction. Our browser modifies the layout of an HTML document with removing horizontal scrolling and minimizing vertical scrolling. This method allows users to easily view the web page by converting into optimal reading style and layout and to easily seek the information just with zooming.

Restaurants implement menu labeling to provide nutritional information to customers in an attempt to help customers select healthy menu items. Considering the increase in food-away-from-home consumption, the purpose of this study was to identify motivators and barriers in restaurant customers regarding use of menu labeling. Data were collected from a survey on restaurant customers in Seoul, Korea. The findings of this study indicate that customers used menu labeling for health reasons. However, barriers to using menu labeling were identified as small font size, difficulty in locating nutritional information display, and difficulty in interpreting nutritional information. In addition, they also suggested expanding the scope of menu labeling for restaurants by including chain restaurants with less than 100 units. The findings of this study offer strategies for the government to improve menu labeling practices for customers.

Raster operations are widely used to display full-color graphics images (or pixmaps) and single-color images (or bitmaps). These features are strongly needed for image processing applications and font output. However, current mobile graphics platforms, including OpenGL ES hardware implementations, do not directly support these features. To fully support those raster operations on the mobile graphics platforms, we interpreted the graphics images as a set of 3D points, and processed those 3D points through the typical 3D geometry pipelines, in a full-software implementation. Our implementation shows sufficient execution speeds, and passed the official conformance tests to show its correctness.

In this paper, proposed is a control system for a galvanometer which is widely used fer laser display, laser processing and marking systems. The galvanometer with mirror is modeled as a second-order dynamic system Based on frequency responses and time domain responses of the developed model, a conventional PID controller is designed And it is implemented using a DSP(TMS320C32) chip with precision A/D and D/A converters. Through frequency response and experimental results, it is convinced that the proposed control system works well in real environment. Furthermore it is very easy to be connected to any PC because of USB communication port, and the cost of the marking system can be lowered very much because the DSP do the all the jobs for generating font motion as well as controlling the galvanometer.
