Chart suggestion method provided by various existing data visualization tools makes chart recommendations without considering the user intention. Data visualization is not properly carried out and thus, unclear in some tools because they do not follow the segmented quantitative data classification policy. This paper provides a guideline that clearly classifies the quantitative input data and that effectively suggests charts based on user intention. The guideline is two-fold; the analysis guideline examines the quantitative data and the suggestion guideline recommends charts based on the input data type and the user intention. Following this guideline, we excluded charts in disagreement with the user intention and confirmed that the time user spends in the chart selection process has decreased.

Wayfinding is a 'Process solving problem to find destination', and it is important to select spatial data for optimal way. Recently, due to the complexity of space and the expansion of the medium of the wayfinding service, it is necessary to the approach on the information design for them. Therefore, the purpose of this study is to propose a meta guideline on the information design for the design of orientation sign, which is an important cognitive clue in the wayfinding. It was conducted in 3 stages, First, a design process was proposed and design elements were derived for each step by literature research related to information and sign design, and analysis of manual for signage design. Second, a meta guideline for information organization and visualization in the three-stage design process was proposed by FGI and analysis. Third, the meta guideline was applied to the sign design on an area for user evaluation to inspect the applicability of the meta guideline. Through the user questionnaire, the possibility of applying the guideline for visualization of directions and spaces, information hierarchy according to spatial characteristics and information priority was identified. It is meaningful in that necessary element for signage design are systematized centering on the process and that it presents a macroscopic methodology according to spatial characteristics.

영상매체를 통한 다양한 정보가 지식을 습득하는 보편화된 수단으로써 자리를 잡아가고 있다. 방송자막은 불과 10여 년 전만 해도 영상의 효과적 전달을 위한 하나의 보조적 수단에 불과했지만 이제는 프로그램의 가치를 높여주는 중요한 정보 중 하나로 꼽을 수 있다. 현재의 방송자막은 SDTV의 가이드라인을 기준 삼아 타 매체에도 그대로 사용되고 있고 수신기 역시 점차 화면이 대형화, 소형화되고 있어 정보전달 면에서 문자의 가독성에 여러 가지 문제점을 지니고 있다. 본 논문에서는 2차의 설문을 통해 전문가 그룹을 대상으로 한 델파이조사를 기반으로 영상화면의 자막크기, 글꼴, 문자속성, 표출효과 등의 시각적 요소와 인지도가 어떤 연관을 가지고 있는지를 고찰하고 OSMU 환경에서의 각 매체별 특성을 고려한 가이드라인을 제안한다.

Virtual reality is a technology that enables users to implement environments that are separate from the real world, and immersion is an important factor in implementing separate environments. However, a variety of studies have been conducted to solve this problem as the lack of awareness of the surrounding environment can lead to an unstable virtual reality game environment. Most studies are focused on solving problems through visualization. On the other hand, because visualizations are generally information that is not relevant to the space of virtual reality, research is needed on the effect of the degree of immersion in virtual reality to which they are applied. The guidelines are necessary because there are differences in individual tendencies and the factors that influence the immersion. In order to solve these two problems, we are going to conduct experiments on two systems: a survey based on the immersion tendency and a visualized communication of information about the surrounding environment. Through these results, we will measure the immersion of individuals and identify the impact of visualizations on virtual reality games by dividing them by their propensity to do so to present guidelines on the creation of virtual reality game environments based on the individual's tendency to engage in immersion.

The worldwide population is aging rapidly. In this circumstance, Korean society is in need of the urgent comprehensive countermeasures that will help the elderly with their health problems and infection control in their daily life. Universal design has supportive, adaptable, accessible and safety-oriental design standards for the elderly. Is this study, we propose the guidelines of the mobile application development based on the application of the universal design for infection control in the elderly. From the perspective of the universal design, there are several important guidelines including 'generalized access', 'simple and intuitive usage', 'low physical effort', and 'visualized language' based on the KCDC(Korea centers for disease control and prevention) principles for the elderly. These findings show that the guidelines for improving the health literacy of the mobile application via universal design are necessary to enhance the health behavior of infection control for the elderly.

With the recent growth of the big data technology market, interest in visualization technology has steadily increased over the past few years. Data visualization is currently used in a wide range of disciplines such as information science, computer science, human-computer interaction, statistics, data mining, cartography, and journalism, each with a slightly different meaning. Big data visualization in smart cities that require multidisciplinary research enables an objective and scientific approach to developing user-centered smart city services and related policies. In particular, spatial-based data visualization enables efficient collaboration of various stakeholders through visualization data in the process of establishing city policy. In this paper, a user-centered spatial big data visualization expression request method was derived by examining the spatial-based big data visualization expression process and principle from the viewpoint of effective information delivery, not just a visualization tool.
