Popping-Up Poster: A Pin-Based Promotional Poster Device for Engaging Customers through Physical Shape Transformation

Promotional media, such as paper posters and digital signage, are installed in shopping malls to recommend products and services. However, it has been reported that many customers tend not to be interested in these promotional media and do not receive the information. When product information is not communicated effectively, advertisers are unable to convey the information they wish to share with customers, and customers miss the opportunity to receive valuable information. To address such issues, a lot of methods have been proposed to make people aware of the presence of media; however, there are not many methods that take into account the delivery of product information to customers. In this study, we propose Popping-Up Poster, a pin-based poster device designed to capture customer attention and convey information through dynamic shape changes. To verify the effectiveness of the proposed system, field experiments were conducted in a café, where its promotional effects were compared with those of traditional promotional media, including paper posters and digital signage. These results show that Popping-Up Poster has the potential to be more effective in recommending products and influencing customer product choices compared to conventional promotional media.

Road and Bridge Blocking System in Flood Situation

Abstract: The system uses hydraulic or mechanical barriers that can be quickly opened in response to rising water levels, preventing access to barriers and bridges. Up to date data from weather forecasters and water gauges provide effective protection to ensure closure times before flooding reaches critical levels. In addition, the central control centre provides timely updates to the public via mobile and digital signage applications, encouraging collaboration with emergency services and local authorities. The purpose of this document is to provide guidance to highway authorities and other relevant organisations on road drainage. One problem that arises during floods is the closure of roads due to flooding, especially on roads located near rivers and canals. Most brides give the height above the highest water level, but the approach to the bridges often does not give the required height. As a result, the road was flooded while the bridge was standing

Cultivating a Culture of Gratitude and Recognition Among Nurses and Staff on a Blood and Marrow Transplantation Unit.

To measure baseline work gratitude among nurses and staff on a blood and marrow transplantation unit; to evaluate the impact of a positive workplace recognition intervention on work gratitude, sense of belonging and community, and job satisfaction; and to explore the relationships among these variables and job satisfaction. In total, 40 survey responses (preintervention =24, postintervention = 16) were collected from nurses and staff on a blood and marrow transplantation unit at a large academic hospital. A pre- and postintervention survey included a demographic questionnaire and the Work Gratitude Scale. Public-facing digital signage was installed and used to project positive recognition, including expressions of gratitude from patients and staff. Those with higher job satisfaction and a stronger sense of belonging and community reported higher work gratitude scores. There were no significant changes in job satisfaction, sense of belonging and community, and work gratitude scores. Creating a positive work environment through gratitude and positive recognition could increase job satisfaction and sense of belonging and community among nurses and staff.

Changing Culture through Pro-Environmental Messaging Delivered on Digital Signs: A Longitudinal Field Study

Delivering effective messages is critical to creating a more sustainable and resilient culture. The explosion of social media has enhanced information access but has often reinforced and polarized pre-existing viewpoints and norms. In contrast, digital signs are an “in your face in your space” technology that have the potential to deliver common content to a diverse local audience. Environmental Dashboard (ED) is a communications platform and set of content applications that combines information on current environmental conditions, real-time resource consumption, positive actions being taken by community members, and a community calendar. We conducted a longitudinal study to assess whether ED content delivered via digital signs in public locations would result in desirable psychological changes within a community. Participants completed surveys in six designated signage locations prior to installation (N = 174) and following two years of continuous exposure (N = 133). We observed increases in pro-environmental social norms among people of color (a demographic emphasized); enhanced awareness of and sense of connection with the local community and ecology; increased self-reported electricity conservation; and increased perception of youth engagement (another demographic emphasized). Changes were mediated by exposure to digital signage. These findings support the hypothesis that content delivered through digital signs can strengthen pro-environmental and pro-social culture within communities.

Fast-response liquid crystal display device with trapezoidal pixel electrodes

ABSTRACT A fast response liquid crystal display (LCD) with trapezoidal pixel electrodes is proposed. The trapezoidal shape of the pixel electrode generates a slanted electric field, eliminating the need for a non-zero pre-tilt angle to prevent random domain formation in the LC. Additionally, the absence of a pre-tilt angle enhances viewing angles. During operation, LC molecules can form virtual walls, increasing anchoring energy and improving response time. At 38% transmittance, the response time is 5.1 ms, while at 60% transmittance, it increases to 8.3 ms. With a circular polariser, the device achieves a contrast ratio of 200:1 and a viewing cone of approximately 18°. Consequently, the trapezoidal pixel electrode FFS cell is suitable for fast LCDs used in automotive displays and digital signage. Its narrow viewing angles with a circular polariser also make it ideal for personal privacy displays and certain mobile displays.

Methods for Adaptive Transformation of Content in Hypertext Format on Corporate TV and Information Kiosks of Educational Institutions

Purpose of the study: to consider and implement in practice a system for displaying content on screens of different resolutions and orientations in relation to an educational institution, using both a pure Smart TV (built-in browser of modern TV) and a player connected to Digital Signage screens. In system engineering, the main emphasis (and, as a result, the key task) is on the absence of duplication of content for different types of output screens (including interactive touchscreen kiosks), which is especially important because the implemented system will be built on free, open-source technologies and integrated into the current university website, which no other proprietary Digital Signage software system can offer.Materials and methods: the study uses different methods of transformation and output of content, but adaptation methods based on cascading style sheets (CSS) are mainly used. The experience of foreign programmers working with adaptive layouts for the web and operating their own blogs was studied (in the “Reference” section). Compromise methods for displaying graphic images and video materials are considered and proposed based on the experience gained during testing of the prototype system.Results: development of a system for displaying content on multi-format screens, requiring minimal subsequent support and intervention from the administrator responsible for filling it with content. An analysis of some potential solutions and their compatibility was carried out, taking into account browser support for CSS3 and HTML5 standards, and working solutions were selected that can be used in the design of individual templates for displaying content in hypertext format and CSS designs (rules) that work for the purpose of the study. The article compares approaches to designing adaptive templates for displaying web content in HTML (hypertext) format. The basic principles are considered under which content intended primarily for a university website can, without a third-party administrator (and also, in some cases, with minimal intervention) be displayed on corporate TV and touchscreen kiosks of universities thanks to the use of cascading style sheets (CSS) and relative units of measurement (vh, vw, vmin, vmax) and tags introduced in HTML5. The article also discusses how to level out the nuances associated with different resolutions of graphic images and screen orientation.Conclusion: the final paragraphs of the article conclude on the nuances of the functioning of the developed system, the effectiveness of which directly depends on methods of implementation and technologies used, chosen and discussed in the article. The implementation of the system will increase the awareness of students of an educational institution about events (announced or conducted), and will allow the system administrator to increase work efficiency by publishing and administering content only in “one window” (for example, on the university website), and the developed output template and/or CSS rules will display it on the internal screens, maintaining readability and perception of information. The developed and tested methods can be used by programmers, working in educational institutions.

Data was collected using a structured questionnaire and tested using SPSS and AMOS. The study showed a positive and significant relationship between digital signage, social media advertising, and consumer buying behavior. Emotions positively mediate digital signage, social media advertising, and consumer buying behavior relationships

Initiatives of environmental marketing and digital signage in the commercial fairs as contribution to the sustainable development

En cada feria comercial se suelen utilizar grandes cantidades de elementos publicitarios con dos propósitos: 1) promocionar la ocurrencia del evento y 2) obtener información de los visitantes que incentive eventuales compras. Usualmente, dichos elementos terminan siendo descartados sin lograr su objetivo, y su fabricación, a partir de materiales altamente contaminantes, crean cuestionamientos sobre el papel de expositores y ferias frente a la responsabilidad ambiental. Por su parte, los visitantes, familiarizados con el uso de la tecnología, muestran una mayor propensión a consumir contenidos digitales en lugar de impresos. Siendo una tendencia evidente, los encargados de la promoción del evento deben revisar e integrar acciones de digital signage e ISO 20121, reemplazando el uso de elementos físicos, para generar efectividad. El presente artículo es una revisión en diversas fuentes que propone una gestión responsable de eventos comerciales que, desde lo ambiental, contribuya a los Objetivos del Desarrollo Sostenible.

Estimating the Social Value of Digital Signage Landmarks as Sustainable Tourist Attractions

As urban tourism increases, digital signage landmarks are frequently utilized to develop and enhance the attractiveness of cities for tourism. However, the benefits of this development for local residents have not been fully explored from a sustainability perspective. Thus, this study aims to quantitatively analyze local residents’ perceptions of digital signage landmarks in urban areas using one of the prominent icons, the Samseong-dong free display zone in Seoul, Korea. To measure the overall value of the landmarks, this study used a double-bounded dichotomous choice contingent valuation method and spike model. Based on the surveys of 600 respondents in Korea, the results show that a household’s willingness to pay to support the landmark annually is KRW 5401 (USD 4) on average in the form of income tax. The perceived annual value for the landmark is about KRW 790 million (USD 60 million), surpassing that of typical tourism attractions in Korea.

Enhancing Pixel Charging Efficiency by Optimizing Thin-Film Transistor Dimensions in Gate Driver Circuits for Active-Matrix Liquid Crystal Displays.

Flat panel displays are electronic displays that are thin and lightweight, making them ideal for use in a wide range of applications, from televisions and computer monitors to mobile devices and digital signage. The Thin-Film Transistor (TFT) layer is responsible for controlling the amount of light that passes through each pixel and is located behind the liquid crystal layer, enabling precise image control and high-quality display. As one of the important parameters to evaluate the display performance, the faster response time provides more frames in a second, which benefits many high-end applications, such as applications for playing games and watching movies. To further improve the response time, the single-pixel charging efficiency is investigated in this paper by optimizing the TFT dimensions in gate driver circuits in active-matrix liquid crystal displays. The accurate circuit simulation model is developed to minimize the signal's fall time (Tf) by optimizing the TFT width-to-length ratio. Our results show that using a driving TFT width of 6790 μm and a reset TFT width of 640 μm resulted in a minimum Tf of 2.6572 μs, corresponding to a maximum pixel charging ratio of 90.61275%. These findings demonstrate the effectiveness of our optimization strategy in enhancing pixel charging efficiency and improving display performance.

Performance evaluation of data embedding schemes for two-dimensional display field communication.

Display field communication (DFC) is an unobtrusive display-to-camera technology that transmits data within the frequency domain of images, ensuring that the embedded data are hidden and do not disrupt the viewing experience. The display embeds data into image frames, while the receiver captures the display and extracts it. Two-dimensional DFC (2D-DFC) focuses on embedding data in the width and height of an image. This study explores two methods to minimize the error rate in 2D-DFC without affecting the quality of the displayed image. The orthogonal method embeds data in the orthogonal direction of an image. On the other hand, the diagonal embedding method strategically embeds the data in the diagonal direction. Experiments show the diagonal method maintains a higher peak signal-to-noise ratio and surpasses the orthogonal embedding method in terms of bit error rate. 2D-DFC is expected to have practical applications in digital signage, advertising and informational displays at airports and train stations, as well as at large-scale displays for events, sports arenas, and performance venues.

Investigating Driver Preferences for Traffic Information Using Digital Signage and Road Surface Holograms

This study investigates road users' information preferences to enhance traffic information provision strategies. Traditional road signs primarily convey static information like speed limits and restricted areas. However, smart street poles now offer the capability to collect real-time road conditions and deliver dynamic traffic updates promptly. Leveraging these smart poles allows for more effective and tailored information delivery strategies. The research examines three types of media for information dissemination: digital signage, road surface hologram, and a combination of both. Additionally, it surveys road users' preferences for information delivery methods, including text, graphics, or a mixture, based on the type of information. Conjoint analysis of 220 responses reveals essential attributes influencing users when they receive information. The findings indicate that a majority of road users prefer a blend of digital signage and road surface holograms, with a notable preference among younger individuals for digital signage. For road surface holograms, the favored approach involves a mix of text and graphics. This study lays the foundation for user-centric information strategies, offering insights into tailoring approaches based on the type of information and user preferences.

DESAIN MODUL SWITCH SELECTOR UNTUK PENGGUNAAN REMOTE CONTROL PADA MULTIDISPLAY DIGITAL SIGNAGE BERBASIS MULTIPLEXER

Digital signage is an electronic device that can display information or announcements digitally. The choice of device depends on the characteristics of the place where the digital signage is placed. Restaurants are one of the places where a large number of digital signage is used. The large number of digital signage can extend the display setting time of digital signage displays. The large number of digital signage units used can also affect the number of remotes used, making it less efficient when setting up displays. Therefore, this design is made to make it easier for users to choose which digital signage display they want to set. This design is in the form of a selector module called a multiplexer-based switch selector module. This module consists of a toggle switch, multiplexer, and infrared receiver as the main components and has 4 output channel which can connect with 4 display digital signage. Tests are carried out using 1 digital signage in rotation for each channel. Digital signage display can respond to the signal emitted by the remote via an infrared receiver connected to the module. Therefore, it can be concluded that the switch selector module in the use of remote control can function properly.

HYDRO: Optimizing interactive hybrid images for digital signage content

In modern society, digital signage installed in many large-scale facilities supports our daily life. However, with a limited screen size, it is difficult to provide different types of information for many viewers at varying distances from the screen simultaneously. Therefore, in this study, we extend existing research on the use of hybrid images for tiled displays. To facilitate smoother information selection, a new interactive display method is proposed that incorporates a touchactivated widget as a high-frequency part of the hybrid image; these widgets are novel in that they are more visible to the viewers near to the display. We develop an authoring tool that we call the Hybrid Image Display Resolutions Optimizer (HYDRO); it features two kinds of control functions by which to optimize the visibility of the touch-activated widgets in terms of placement and resolution. The effectiveness of the present method is shown empirically via a quantitative user study and an eye-tracking-based qualitative evaluation.

Conversational Context-sensitive Ad Generation with a Few Core-Queries

When people are talking together in front of digital signage, advertisements that are aware of the context of the dialogue will work the most effectively. However, it has been challenging for computer systems to retrieve the appropriate advertisement from among the many options presented in large databases. Our proposed system, the Conversational Context-sensitive Advertisement generator (CoCoA), is the first attempt to apply masked word prediction to web information retrieval that takes into account the dialogue context. The novelty of CoCoA is that advertisers simply need to prepare a few abstract phrases, called Core-Queries, and then CoCoA automatically generates a context-sensitive expression as a complete search query by utilizing a masked word prediction technique that adds a word related to the dialogue context to one of the prepared Core-Queries. This automatic generation frees the advertisers from having to come up with context-sensitive phrases to attract users’ attention. Another unique point is that the modified Core-Query offers users speaking in front of the CoCoA system a list of context-sensitive advertisements. CoCoA was evaluated by crowd workers regarding the context-sensitivity of the generated search queries against the dialogue text of multiple domains prepared in advance. The results indicated that CoCoA could present more contextual and practical advertisements than other web-retrieval systems. Moreover, CoCoA acquired a higher evaluation in a particular conversation that included many travel topics to which the Core-Queries were designated, implying that it succeeded in adapting the Core-Queries for the specific ongoing context better than the compared method without any effort on the part of the advertisers. In addition, case studies with users and advertisers revealed that the context-sensitive advertisements generated by CoCoA also had an effect on the content of the ongoing dialogue. Specifically, since pairs unfamiliar with each other more frequently referred to the advertisement CoCoA displayed, the advertisements had an effect on the topics about which the pairs spoke. Moreover, participants of an advertiser role recognized that some of the search queries generated by CoCoA fit the context of a conversation and that CoCoA improved the effect of the advertisement. In particular, they learned how to design of designing a good Core-Query at ease by observing the users’ response to the advertisements retrieved with the generated search queries.

Effects of Training Images on CNN-Based Demodulation for Digital Signage and Image Sensor-Based VLC

This paper studies a visible light communication (VLC) system using a digital signage and an image sensor. The authors have focused on the demodulation part of the communication system, which modulates data signals without disturbing the visual information on the digital signage, and have proposed a novel concept that uses machine learning to demodulate the data signals from images received by the image sensor. However, it has not been fully clarified which parameters of the training images contribute to the performance of the machine learningbased demodulation. This paper extends the convolutional neural network (CNN)-based demodulation method and clarifies how much the number of parallelized data signals and the number of patterns of data signals in the training images contribute to the demodulation performance. The results show that the performance improves with the number of parallelized data signals in the training images, and that half of the signal patterns are sufficient for learning.
