본 논문은 가상스튜디오(TV)에서 인터랙티브 가상 바닥을 위한 시스템 및 그 어플리케이션을 제안한다. 우리는 가상스튜디오에서 연기자와 바닥 그래픽간의 단순한 키(Keying) 합성 이질감을 줄이고자, 연기자를 추적하여 발 위치에 다이나믹한 발자취 표현이 가능한'인터랙티브 가상바닥' 어플리케이션을 구현하였다. 이것을 위해 마커 없이 연기자의 위치를 추적하도록 키넥트와 같은 모션인식 카메라를 사용하여 간편한 연기자 발 추적 시스템을 개발하였으며, 이것을 이용하여 연기자와 바닥간의 ' 가상 발 터치(Virtual Foot Touch)' 방법 및 일기예보용 인터랙티브 가상바닥(Interactive Virtual Floor) 어플리케이션을 개발하여, 연기자의 발이 바닥을 터치하는 위치마다 계절별 다이나믹한 발자취를 구현하였다. 그 결과 인터랙티브 가상 바닥의 합성결과가 기존의 가상스튜디오에서의 단순 합성보다 더 사실감 있고 자연스러운 합성결과를 보여준다. 우리는 본 시스템과 어플리케이션을 정규 뉴스 프로그램의 일기예보 방송에 적용하였다.

What is an appropriate length of an article in the mobile era producing new tastes of contents combining computing and mobile communication? Is it still valid to have a lengthy article as high level journalism even in the mobile era? Is there any possibility to have a short article combination to give us readability and the amount of information? This study aims to find some answers to these questions. The length of articles were controlled with a field experiment; from an article of 346 syllables(including spaces between syllables) which does not need finger scrolling on a mobile phone to articles of 633, 1033, 1368 syllables(including spaces between syllables) which frequently appear in newspapers and broadcasting news program. All the main themes were same for 4 articles which have different length. Three hundred and eighty four students viewed one of the 4 articles through mobile phone or newspaper. Each participant checked their preference and evaluated quality on the article, were asked to recall contents of the article. In newspaper group, articles with 346 or 1033 syllables were highly evaluated. Mobile group seemed to prefer articles of 346 or 633 syllables. In conclusion, we need to consider various strategies shortening the length of an article into 346 or 633 syllables as a basic format to meet the neEds of mobile era.

Recently, Big Data is a buzzword in the creative economy generation. The organizations related to spatial information society focus on building the spatial big data systems. As spatial big data is a combination of spatial information and big data, the data visualization is essential in order to utilize them efficiently. One of the great methodologies for data visualization is infographics. Nationally, Chousn.com initiated the infographics news in 2010. Korean Administration Branches also recognized the importance of infographic and they adopted infographics for their briefings from 2013. Internationally, Visual.ly is leading company in the infographics market and they produced noticeable interactive infographics for Egypt Parliamentary Elections results. In the defense part, Guardian's datajournalism of Afghanistan war log was a good example of utilizing infographics. Throughout the research, five requirements are extracted. First source data should have precision and accuracy in terms of time and space manner. Second, infographics images have a compressibility. Third, the infographics is properly processed for military commanders. Fourth, sharing, openness and communication are essential for high quality infographic. Lastly, infographics should be an analytic tool for predicting future event based on the past data. Infographics is not a direct representation of data but an analytic tool for helping user's choice and decision in critical moments.
