Augmented reality technology was invented for military purposes at the beginning. But the development of wireless and location based technology in 2000s makes AR services reach the age of innovation. Especially, it attracts attention as a media which enriches our perception. There is a potential that it can extend the virtual information in the real world from optical sense to auditory, tactile, and olfactory sense. This study proposed the interactive information service system and method based on AR. To do it, technical background on AR was analyzed and a method to apply the technology was examined. Especially, as a eco service, this study proposed new information service using 2D bar code in a library for user need and convenience in ubiquitous environment. The proposed service system can optimize practical utilization of information resources in virtual and real reality as consolidating analog and digital resources in a library.

우리나라는 세계 최고 수준의 IT 인프라를 기반으로 네트워크 및 서비스 융합, RFID 등 u-IT 서비스 확산 등을 통해 유비쿼터스 사회로 빠르게 진입하고 있다. 향후 디지털 융합이 가속화됨에 따라 시간과 공간의 제약 없이 원하는 정보의 획득 활용이 증가하고, u-Health, u-learning 등 IT가 타산업과 융합되면서 높은 부가가치를 창출할 것으로 전망 된다. 그러나 정보화의 급속한 진전에 따른 사회 전반의 편의성과 효율성이 향상하였으나, 해킹 바이러스, 개인정보 유출사고, 스팸 등 역기능으로 인한 피해도 확산되고 있다. 최근에는 네트워크 방어체계를 무력화시키는 지능화된 해킹, 대량의 고객정보 유출, 사회공학 기법을 활용한 피싱 등 이용자의 자산과 프라이버시를 침해하는 사이버범죄 증가 등으로 이용자자산과 권리 보호관점에서의 정보보호의 중요성이 부각되고 있다. 향후 시간과 장소에 상관없이 지식정보를 활용하여 편리하고 쾌적한 생활을 누리게 하는 지식정보사회는 예측 불가능한 위험이 곳곳에 산재한 정보위험사회로의 진입을 의미 할 수도 있다. 그러므로 미래사회에서 예상되는 위협을 예측하여 효과적으로 사전에 예방할 수 있는 체계를 마련하는 것은 안전하고 신뢰할 수 있는 지식정보사회를 향유하기 위한 전제조건으로 작용한다. 이에 본고에서는 미래 지식정보사회에 대비한 정보보호 전략으로 안전한 u-사회 청사진 설계 및 환경조성 선도와 국제화, 사이버위협 예방 및 대응체계의 입체적 조화와 융합, 정보보호 기술 제품 산업간 선순환 촉진과 성장 등 3대 전략을 설정하고 실행방안을 제시한다.

Parking guidance and information systems have been introduced to response the inefficient and inconvenience use of parking facilities. While advanced countries have reached effective use of parking guidance information system, the Republic of Korea has yet suffered from the lack of full use of advanced technologies. This study proposes an algorithm designed for a systems utilizing the USN technologies. A field test was performed. The test results showed that information from the proposed system is much reliable when compared to the one from the existing.

There are relatively inactive discussions about applying ubiquitous technology (uT) to traditional marketplace. If u-Market which affords to promote customer shopping convenience and on/offline shopping experience is implemented, then traffic of visiting customers as well as the revenue of the market will increase. Ultimately, it will lead to revitalizing traditional market. For this purpose, we developed a realistic u-Market service scenario with restricted uT considering spatial limitation and poor infrastructure of the physical marketplace. Based on u-Market service scenario, we have empirically investigated the determinants of u-Market service acceptance of the actual customers of traditional marketplace. We hope the results of this study will help in improvement of u-Market system development and service feasibility.

Along with the development in cutting-edge digital technology, the street space is also being changed. Mobile telecommunication units and internet give a big change in a human being's lifestyle. And the ubiquitous computing is proceeding with expanding its application range from the indoor space to the street space. As the street furniture is the convenient facility that allows a human being's life in street space to be abundant, it is getting advanced. First of all, in terms of such phenomenon, this study analyzed the cases of a research on application of street space and the actual condition of a change in the number of individuals for the street furniture, through a literature research of ubiquitous. Also, it researched into the realities of using the street furniture of the walking-desired streets at Daehac-ro and Hongdae district, where are two representative places related to digital generation. The next was carried out FGI (Focus Group Interview) with users of the street space in front of Hongik University and managers of the street furniture, and was researched into the use & management behavior, and recognition level on the street furniture. Thus, the key elements were extracted such as interchange of information for cultural activities, automation for interaction variability in function. Finally the core elements for future vision of street furniture in this digital era were extracted in 3I, namely, Information, Intellectualization, and Integration. This is considered to be applied to the establishment of direction in the process of high-tech digitalization in street furniture related to information hereafter.

Real-time controllability has been a major challenge that should be addressed to ascertain the practical usage of the management systems. In this regards, for the first time, we proposed and implemented an IoT(Internet of Things)-based water tank system to improve convenience and efficiency. The reservoir can be effectively controlled by notifying the user if the condition of the reservoir is unstable. The proposed system consists of embedded H/W unit for sensor data measuring and controling, application S/W for deployment of management server via web and mobile app, and efficient database structure for managing and monitoring statistics. And machine learning algorithms can be applied for further improvements of efficiency in practice.

This study sheds light on the entertaining aspects of Media Pole that is located in Gangnam U-Street and proposes design that considers the aspects of the form, experience, contents and communication of scribbling. Functioning as public digital media, Media Pole provides various convenient services related to the area. According to the research on user's behavior upon Media Pole, photo related services, which can be categorized as entertainment, were found to be the most frequently used services among various services. Taking user's behaviors into consideration, this study highlights the entertaining aspects of Media Pole and suggests design that applies the playfulness of scribbling. The playful characteristics of scribbling were applied to the Media Pole's user interface, interaction, application and interlocking functions. As a result, users are expected to increase as Media Pole becomes more playful than before. Since scribbling is an act of intrinsic human's desire, it will attract users to participate more voluntarily. It can be applied not only to Media Pole, but to any public digital media devices.

수화의 인식 및 표현 기술에 대한 관련 연구는 수화 인식을 통한 건청인과의 의사 전달, 가상현실에서의 손동작 인식 등을 대상으로 여러 방면으로의 접근 및 연구 결과를 도출하고 있다. 그러나 이들 연구의 대부분 데스크탑 PC기반의 수신호(Hand signal) 제어 및 수화 - 손 동작 인식에 목적을 두었고 수화 신호의 획득을 위하여 영상장비를 이용하였으며 이를 바탕으로 단어 위주의 수화 인식 및 표현에 중점을 둔 수화 인식 시스템의 구현을 통해 비장애인과의 자유로운 의사소통을 추구하고 있다. 따라서 본 논문에서는 햅틱 장치로부터 사용자의 의미있는 수화 제스처를 획득하기 위한 접근 방식을 차세대 착용형 PC 플랫폼 기반의 유비쿼터스 환경으로 확대, 적용시켜 제스처 데이터 입력 모듈로부터 새로운 정보의 획득에 있어 한계성을 극복하고 사용자의 편의를 도모할 수 있는 효율적인 데이터 획득 방안을 제시한다. 또한 퍼지 알고리즘 및 RDBMS 모듈을 이용하여 언제, 어디에서나 사용자의 의미 있는 문장형 수화 제스처를 실시간으로 인식하고 표현하는 수화 제스처 인식기를 구현하였다. 본 논문에서는 수화 제스처 입력 모듈(5th Data Glove System과 $Fastrak{\circledR}$)과 차세대 착용형 PC 플랫폼(embedded I.MX21 board)간의 이격거리를 반경 10M의 타원 형태로 구성하고 규정된 위치로 수화 제스처 데이터 입력모듈을 이동시키면서 5인의 피실험자에 대하여 연속적으로 20회의 반복 실험을 수행하였으며 사용자의 동적 제스처 인식 실험결과 92.2% 평균 인식률을 도출하였다.
