This study suggested the alternatives for improving consumers' engagement with digital signage (DS) by analyzing the researches of the effectiveness of DS in marketing and public areas, which is recognized as an essential communication tool for commercial or public matters. According to the results, affective DS ad content of DS resulted in positive shoppers' buying behaviors and perceiving buying environment; DS was also effective for public affairs, which how proper channel and message for the target public resulted in solving community problems. However, it was rare to measure precisely the level of consumers' engagement with DS content and what DS content aroused higher engagement in both areas. Thus, DS content should be more customized based on multiple converged contents for consumers' engagement and the research efforts of DS should be focused on the development of not only its device technology, but also creative content.

Advances in IoT data analysis technology have made it easier to analyze situation and provide interactive services based on the context. Most of digital signage application have been used to provide information uni-directionally, but in the future it will evolve to provide personalized content according to the individual user situation and responses. However, it is not easy to modify or apply the existing interactive digital signage platforms due to their hardware dependency. The proposed platform is modularized by dividing main functions into two, the cloud and the edge, so that advertisement resources can be easily generated and registered. Thus, interactive advertisement can be rendered in a timely manner based on sensor analysis results. At the edge, personal data can be processed to minimize privacy issues, and real-time IoT sensor data can be analyzed for quick response to the signage player. The cloud is easier to access and manage by multiple users than edge. Therefore, the signage content generation module improves accessibility and flexibility by handling advertisement contents in the cloud so that multiple users can work together on the cloud platform. The proposed platform was developed and simulated in two aspects. First is the provider who provides the signage service, and second is the viewer who uses the content of the signage. Simulation results show that the proposed platform enables providers to quickly construct interactive signage contents and responses appropriately to the context changes in real-time.

팬데믹이후 온라인 커뮤니케이션이 가속화되면서 개인화의 현상이 두드러지고 있는 가운데 도시의 정보시스템의 많은 부분들이 디지털 트윈으로 가고 있다. 때문에 오프라인의 사이니지 등은 이미 개인화에 익숙한 사용자에게 만족도나 낮고 이를 반영하여 다양화시키기에는 많은 예산이 소요되며 물리적 한계가 있다. 본 연구는 사용자 중심 프로세스의 기술 융합 연구를 통해 이러한 오프라인 정보 표기와 전달 등의 문제점을 해결하고자 하였다. 본 논문은 이러한 목적을 가지고 개인화 기반 도시 인포메이션 시스템의 물리적 사이니지와의 정보 데이터 간의 상호운용을 실현화하는 연구를 진행하였다. QR 코드 등 비쥬얼 코드-기반 기존의 인터랙션 기술들의 장점을 활용하고 AI 기반의 필터 시스템을 도입하여 도시 복합정보데이터와 개인데이터와의 연동 및 변별 시스템을 설계하여 AR서비스 환경을 디자인 하였다. 개인화 서비스를 위하여 'Personal Data'와 타사용자의 'Feedback Data를 기존의 클라우드 정보와 AI-Analytic-Process에 개입시켜서 개인화 기반의 서비스 시스템 모델로 개발하였다.

In this paper, we propose a digital signage method that can control the contents of the screen and download the desired files to individual smart terminal with no touch of digital signage screen by using Kinect. The main features and contributions of the proposed method are as follows. First, can solve the problems such as the risk of bacterial infection, not cleanliness on the screen as well as maximize advertising effectiveness. Second, can support bi-directional communications with computer while we touch only wanted advertisements. The performance evaluation shows the effectiveness of the proposed method. Especially, we can see that the proposed system operates through the recognition of user's actions when the cursor is within the scope of a certain coordinate and the file transfer time to download information is different depending on the PC performance and the version of personal smart device.

This study is to find the effectiveness of advertising acceptance through NFC advertising and mobile in a cinema environment. The results are as follows. First, personification and participation among interacitivity factors had a positive impact on advertising acceptance. Second, advertising value of NFC advertising had a partially positive impact. Perceived usefulness and ease of use, perceived entertainment, and innovation alos had a positive impact on advertising acceptance. Finally, interactivity, followed by advertising value, had impact on the acceptance of NFC advertising.
