Signage can be defined as the media device that provides specific information to many unspecified users in public places. Recently applied context-aware technology, signage provides personal on-demand information services in a way that can continue to evolve. The purpose of this study is to analyze characteristics of types which users identify signage on the perceptions and attitudes about consideration of the perspective of the experts in the fields. The research is carried out by applying Q methodology with in-depth interview. First, interviews are conducted to determine the perceptions and attitudes of experts and practitioners on signage. Thereafter users' perceptions and attitudes toward signage are classified by each types using Q methodology. The first type is named as 'signage as smart media', the second type is named as 'signage as passive media', and the third type is named as 'signage as interactive media' is named. The results of this study will be useful guidelines for conducting further academic researches and R&D.

디지털 사이니지는 생활 속에서 소비자들과 소통할 수 있는 디지털 매체로서 사용자와의 양방향 커뮤니케이션이 가능하고, 활용범위가 다양하기 때문에 효과적인 광고 매체로서 활용되고 있다. 최근에는 고화질의 디스플레이가 스마트폰과 센서를 이용한 사용자 맞춤형 기술로 개발되면서 스마트한 형태의 디지털 사이니지로 변화하고 있다. 이에 본 연구에서는 소비자의 관심과 선호 정보에 기반한 데이터를 수집하고 이를 바탕으로 소비자에게 맞는 콘텐츠 및 광고를 제공하기 위한 기술을 개발함으로서 향후 점점 확대되고 있는 디지털 사이니지 시장에 필요한 고객 참여형 정보제공 기술 개발에 기여하고자 한다.

센서/외부사건 연동을 지원하는 인터랙티브 디지털 사이니지(Interactive Digital Signage)가 활발히 전개되고 있다. 그런데, 현재 전개되고 있는 대부분의 인터랙티브 사이니지 시스템은 정해진 인터랙션에만 맞추어 설계되어 지원되기 때문에, 추가적인 인터랙션 기능이 요구되는 경우에 재프로그래밍하여야 한다. 다양한 센서 입력, 외부사건 발생 등에 대한 반응을 유연하게 지원하는 데 있어서 규칙엔진 지원이 유용하다. 본 논문에서는 규칙 메타데이터 변환 및 이의 규칙엔진과의 동기화 방안을 제시하고, 이를 활용하여 다양한 센서/외부사건 연동 인터랙션을 유연하게 지원하는 규칙엔진 기반 인터랙브 기지털 사이니지 시스템의 설계 및 구현을 보고한다.

반도체 디스플레이 기술과 정보통신 기술의 발전으로 디지털 사이니지는 기존의 단순 옥외 광고매체에서 탈피하여 이용자 맞춤 광고나 정보를 제공 및 스마트폰과 연동하여 콘텐츠 제공 가능한 시스템으로 발전하고 있다. 본 연구에서 디지털 사이니지의 작동오류의 위험성을 낮추며 비용절감을 할 수 있도록 제어 서버의 역할을 축소시키고 엣지 영역으로 서버의 역할을 최대한 분담하는 서버리스 기반 디지털 사이니지 시스템 구축 가능성에 대해 연구한다.

We propose an age estimation-based smart digital signage for the next-generation airport service. The proposed system can recognize the face of the customer so that it can display the selective information. Using a webcam, the system captures the face of the customer and estimates the age of the customer by calculating the wrinkle density of the face and applying bayesian classifier. The developed age estimation method is tested with a face database for the performance evaluation. We expect the new digital signage may improve the satisfaction of customers of the airport business.

Digital signage provides flight and airport information to the airport visitors and passengers. However, the digital signage has efficiency problem by displaying one type of advertisement to every customers regardless of their personality. We may solvel the inefficiency problem by using a smart digital signage which can recognize the characteristics of the customer We presents a smart digital signage with sex recognition function. The smart digital signage can recognize the sex of the customer to display the custom-made advertisement in realtime so that we can increase the satisfaction level of the airport passengers and visitors.

Digital signage is referred to as a smart electronic display system that delivers multimedia-based information and advertisements to customers. Typically, the digital signage starts its playback after downloading a list of multimedia contents from network storage to its local disk. However, a way of downloading the entire contents before its playback entails a long initial delay time. In this paper, we formulate a problem of the initial delay time and provide a solution to compute a minimally demanded initial delay time according to a given network bandwidth and qualities/sizes of the multimedia contents. In addition, we analyze the performance of the proposed solution with various multimedia contents on digital signage.

TV display which existed only in house started to show up out of house around us and now it found naturally its place in everywhere like street, bus, subway and elevator. It is called digital signage which showed up through digitalization of sign, that is, sign board and bulletin board. The distinction of digital sign from existing signs is that the latter one should go through physical process like removal after installation every time its contents are changed but the former one can produce its various outputs flexibly once it is installed. Also existing sign may be static image or 2 or 3 pieces of image to express simple motion while digital sign can contain multi media contents luxurious in design and motion. This paper confined the range of contents in digital signage in bus and subway. It needs to analyze characteristics of mass transportation-people of use, consumer by place and time, accommodation environment for consumer etc and arrange planned contents along with time and place. Developments of dedicated contents suitable to those digital signages will harmonize with place and time and promote the realm of digital signage which provides variety of experience to consumer and with which communication is possible and which is distinctive. Furthermore we may expect the birth of smart signage as a new media, in which fun and art are combined.

Digital Signage is outdoor media to provide each content and message through digital displays instead that posters and signs are displayed on public facilities. Recently, digital signage have been popular to deliver variety information and advertising on the rapid development of intelligent digital imaging devices based LCD, LED. Continuously digital signage demand and market are growing because digital signage feature is able to capable of interactive communication. Digital signage is expected that digital advertising market is continue rising in spite of global economic downturn at various research institutions, and it is expected to replace traditional media advertising in a new way with the coming digital signage at convergence media side.

This study is based on the 'National Pilot Project on Digital Signage in Sejong Special City', one of the pilot projects initiated by the Ministry of Public Administration and Security. This project was an attempt to present the digital signage as a 'public service content platform' integrated with smart technologies. This study suggests that the planning strategy for placing public service contents on digital signage platform should focus on interests of local communities or users rather than high-tech suppliers of digital signage. In consideration of growing needs for smart technology-based public service, this study concentrates on the strategy for developing 'public digital signage services'. In addition, 'digital signage service tools' were designed to easily establish or execute the strategy. The aim of this study is developing the strategy to make digital signage a public cultural service platform as well as a digital advertisement tool. The final goal of this study is to demonstrate public value creation performance of the 'Revitalisation Project of Sejong City's Commercial Districts', which was possible thanks to the proactive involvement of citizens coupled with progressive utilization of interactive media.
