Since people with visual impairments are mostly hard to access the Internet they have been neglected from the information-oriented society. Therefore, the contents which consider the web accessibility to readily access to the web by people with visual impairments are an essential component. In this paper, we developed the contents to improve the web accessibility for people with visual impairments. To provide easy access to the web by people with visual impairments, we analyzed the existing web sites for blind people and considered a concise design, and hierarchical structure. Using the PHP, CSS, and Javascript, the necessary functions for the visually handicapped such as focusing, shortcut key, and text equivalent are implemented. The results which are tested by blind users prove the efficiency of the proposed contents.

시각장애인은 활동을 하는데 있어 많은 제약이 따른다. 특히 사물을 만지거나 음성을 이용하여 정보를 얻어 이동해야 하는 어려움을 겪는다. 공공기관 및 민간기업에서는 시각장애인의 어려움을 해결하기 위하여 다양한 지원방안을 내놓고 있지만 여전히 미흡한 것이 현실이다. 이 중 시각장애인이 사용하고자 하는 기기에 설치된 점자판에 접근하는데는 특히나 많은 어려움이 발생한다. 본 논문에서는 이러한 시각장애인 및 저시력자들이 효과적으로 점자판에 접근할 수 있는 시스템을 제안한다. 제안시스템은 블루투스를 이용하여 음성으로 시각장애인들이 이용하려는 시설 및 기기 등에 쉽게 접근할 수 있도록 도와줌으로써, 사회적 약자의 어려움을 해소하는데 많은 도움을 줄 수 있을 것으로 판단된다.

In this study, we contemplated types, essence, characteristics of text data which is material for visual expression of text visualization part of data visualization research and also analysed the multidirectional means of expressive approach for it. Studies of text visualization are spread dramastically under the influence of computer development, open data, wide use of visualization tools, etc. For these reasons, text visualization works have been creating as art works or output of research through various inter-discipline convergent research with engineering, art, humanities, sociology, etc. Nevertheless the theoretical studies on text data itself and its visualization, and also systematic analysis of its approach are rarely made. Data is target of understanding and interpretation, and it has infinite information and possibility with process and approach for it. Considering the attainable status of data in future human society, text visualization which is convergent academic field of study starting with understanding and interpretation of data needs further methodological research and theoretical accumulate.

In the knowledge and information society, there is an increasing importance of information, being unable to access this information becomes a huge disadvantage. Blind and visually impaired users who are using assistant equipment such as screen readers are the very class that is having trouble accessing the web content that public libraries provide. In this research 10% of each region's libraries were picked as a research sample. Most of the web content that the public libraries provided did not meet the Internet web content accessibility guidelines as a Korean standard. Also evaluation into web accessibility by the visually impaired was also low. This research suggests some solutions for libraries to reduce the disadvantages that are put upon visually impaired people from various views such as perceivable, operable, understandable, and robust.

정보 시각화는 컴퓨팅 장치의 디스플레이 성능, 연산 능력, 대량의 데이터 관리 등의 기반 기술 확충으로 더욱 발전할 수 있었으며, 웹과 함께 등장한 인터랙티브 미디어, 소셜 미디어와 같은 비정형적 빅데이터를 주요 대상으로 다루면서 최근 이슈가 되고 있다. 이러한 정보 시각화 기술은 인간의 정보 지각 능력의 중추가 되는 시각을 중심으로 집중됨에 따라 보다 직관적이고 효율적인 정보 지각과 인지를 가능하게 했지만 다른 한편으로는 시각장애인들의 정보 접근성 문제를 야기 시키기도 했다. 이에 본고에서는 정보 시각화라는 큰 틀에서 다양한 시각화 방법과 함께 시각장애인을 위한 정보 접근성에 대해서 다루고자 한다. 정보 시각화의 정의와 분류 및 최근 컴퓨팅 환경의 변화에 대응한 가시화 방법론 등의 기술 동향에 대해 살펴보고 시각장애인을 위한 정보 표현 기술의 발전 동향을 함께 서술한다.

This paper discusses the design of location optimization visualization and feasibility of 3 dimensional visualization techniques. In generic GIS visualization of location analysis, 2 dimensional visualization techniques have been used to map location elements and model solution, such as displaying demand and supply points, drawing connecting lines(e. g. spider line) of optimal locations to their demands, and representing density of location variations. Nevertheless, current GIS and location analysis literatures have little attentions in 3D visualization applications for location optimization problems. Previous research has been neglected 3D visualization of solution performances and its evaluation of solution quality. Consequently, this paper demonstrates potential benefits of 3D visualization techniques and its appropriate GIS applications for location optimization analysis. The visualization effectiveness of 3D approaches is examined in terms of spatial accessibility, and solution performance of optimal location models is evaluated. Finally, this paper proposes extensive 3D visualization perspectives for location analysis and GIS research as a further research agenda.

Information technology and internet became necessities of life facilitating communication and information access. Physically handicapped people, who cannot access to new Information easily due to economic, technical and physical handicaps, are likely to live with severe disadvantage in the high-speed information society in which information access right is considered as one of the basic human rights. Therefore, It is highly desirable to develop and improve library service programs for visually imparied at public libraries. In this study, the analyse of service activities for the visually unpaired at Hanbat Public Library and the investigation of user's needs and provider's points of view of staff members through individual Interviews were followed by the propositions gor the Improvement of services at local public libraries. And the consrtuction of cooperative networks with proper role-shares among service rooms for visually Imparired In public libraries, special libranes, social welfare organigations and government offices was confrimed to be the most urgent task.
