“…Mechanical and electrical engineering information modeling, also known as BIM technology, can be applied to communication project construction engineering to simulate and model communication engineering (Ghaffarpasand & Pope, 2024;Kim, Singh, & Jung, 2024). Based on communication engineering data, three-dimensional or three-dimensional modeling can be formed to reflect the real situation that occurs during the construction process of communication engineering.…”

Display field communication (DFC) is a frequency-based display-to-camera (D2C) communication technology. The digital display and the camera act as transmitter and receiver, respectively, and data are transmitted in a video via the D2C link. The essence of DFC is to minimize image distortion for the user while concealing data within the image for transmission. Unlike traditional Video-DFC methods that may suffer from high error rates due to reliance on a single reference image, our proposed Interpolated Video-DFC technique employs a novel interpolated reference image estimation strategy. This method significantly enhances data detection by leveraging interpolation between two reference image frames, enabling accurate estimation of each reference image frame corresponding to data-embedded frames. Comparative experiments highlight the advantages of our method, showing a data rate improvement of approximately 2.3kbps for frame packet length N = 10. Additionally, we achieved a substantial reduction in error rates to approximately 69% lower than those of conventional methods. These findings indicate a promising direction for improving the performance and reliability of D2C communication systems.

Display field communication (DFC) is an emerging technology that enables seamless communication between electronic displays and cameras. It utilizes the frequency-domain characteristics of image frames to embed and transmit data, which are then decoded and interpreted by a camera. DFC offers a novel solution for screen-to-camera data communication, leveraging existing displays and camera infrastructures. This makes it a cost-effective and easily deployable solution. DFC can be applied in various fields, including secure data transfer, mobile payments, and interactive advertising, where data can be exchanged by simply pointing a camera at a screen. This article provides a comprehensive survey of DFC, highlighting significant milestones achieved in recent years and discussing future challenges in establishing a fully functional DFC system. We begin by introducing the broader topic of screen–camera communication (SCC), classifying it into visible and hidden SCC. DFC, a type of spectral-domain hidden SCC, is then explored in detail. Various DFC variants are introduced, with a focus on the physical layer. Finally, we present promising experimental results from our lab and outline further research directions and challenges.
