Augmented Reality in Context of Industry 4.0

Extended-Reality Technologies: An Overview of Emerging Applications in Medical Education and Clinical Care.

The rapid development of the Augmented Reality (AR) technology has brought new possibilities regarding the enhancement of user experiences in various industries, and the retail will be one of the first to receive it. In this paper, the research questions are put regarding the application of AR in shopping malls to provide a hotel and interactive shopping experience. The AR technology applied to mobile applications and smart devices will assist customers with visualization of the products in 3D and information superimposition in real-time, and give AR instructions that will guide the customers through the intricate plans of the mall floor. The proposed system will also enable retailers to find new methods of interactive marketing, advertise customized promotion and devise methods of customer engagement. An AR system prototype was developed then tested in a simulated mall environment to assess the enhancement of user experience, navigational outcomes, and product engagement. The findings suggest the system is beneficial to enhancing user satisfaction in the mall, navigating better, and entail greater promotion content engagement. This research demonstrates how AR can improve user experience in malls, create more foot traffic into a mall, and provide insights through data for shoppers, retailers, and mall operators. Future research will be conducted on scalability options for the AR system, integration with wearable AR devices for real-time analytics that will improve the experience of a smart retail environment.

Augmented Reality is considered one of the most promising technologies for Industry 4.0. Augmented Reality allows to display the needed information at the right time and to locate it in the desired space, superimposing it to the real world. In this way, it could simplify the work of industrial operators in a variety of tasks, from planning and commissioning to assembly and maintenance. Despite the growing research interest and efforts for the development of Augmented Reality applications and technologies for the industrial domain, Augmented Reality is still rarely used in real industrial procedures, often remaining at a conceptual level. In fact, developers fail to completely answer the actual needs of industries and workers because of a lack of knowledge of the context and the absence of guidelines to drive the design and development of Augmented Reality applications. One of the open issues is the choice of the proper visualization methods to display technical information in Augmented Reality, which is not trivial. Both the paper-based documentation, based on text and illustrations, and digital documentation, including CAD models and image or video-based tutorials, present different criticalities when adapted to the Augmented Reality technology. Other visual material has been developed specifically to be used in Augmented Reality, but it is difficult to use because of a lack of standards which are instead present for the former paper-based and digital documentation. In this work, we categorize and compare different Augmented Reality visual assets, illustrating their advantages and disadvantages and providing directions for future research.

The Covid-19 pandemic has hit Indonesia since the beginning of 2020 and is still continuing. The education sector has experienced a considerable impact, face-to-face learning must be replaced with all-online activities. Many problems arise from online learning, such as inadequate infrastructure, an ineffective learning system and difficulties in understanding the material. Medical education has an impact on the current situation because most of the learning uses infrastructure and direct practice, it is necessary to have alternative learning methods that can improve the quality of learning. Currently, video conference media technology can assist learning activities so that instructors can still explain material to students through virtual media. For medical students who need practice and infrastructure facilities, this technology is still not enough to support their learning media. The idea came up “Application of Learning Module in Health Field based on Extended Reality (sub chapter: Augmented Reality)” This application combines Virtual Reality, Augmented Reality, and Mixed Reality. Augmented reality is a technology that is suitable to be implemented in medical learning because students do not need to prepare anything to perform simulations, just devices and internet networks. For feeding and drinking to the elderly, some items are needed to start the practicum, with this augmented reality there is no need to prepare all of these items, and also reduce contact with other people during a pandemic like this. Users can connect to each other in different devices and environments according to their respective devices. In this application, Augmented Reality acts as a technology that combines the real and virtual worlds by adding virtual objects into the real world. Users can use devices that have cameras such as cellphones or laptops so they can see virtual objects. This virtual object can be seen by all users and each user is able to interact with it in real time. As for the temporary test results, it was found that Augmented Reality has been tested and integrated with other immersive technologies with Web-XR. Interaction in Augmented Reality on Web-XR using a touch screen as well as several nursing SOP have been created and simulated using Augmented Reality technology. As for the final test in this final project, Augmented Reality technology based on WebXR has been running smoothly according to the specifications of the device used to open WebXR. If the device used to access WebXR has a high specification, then WebXR will run optimally, otherwise when the device specification is low, WebXR will not run optimally. The interaction used in WebXR-based Augmented Reality is touchscreen. The author tested this system to the user, the user here is a medical student. testing proves that this system is very helpful in terms of efficiency, users don't need to prepare tools repeatedly when they want to do simulations, just open WebXR and users can do the simulations provided. In testing the system, the author uses the PIECES framework (Performance, Information, Economics, Control and Security, Efficiency, Service) and produces an average score of 4.1. Then the user is categorized as satisfied with the system that was built.

In today’s world, people increasingly rely on mobile apps to do their day-today activities, like checking their Instagram feed and online shopping from websites like Amazon and Flipkart. People are depending on WhatsApp and Instagram stories to communicate with local businesses and to leverage the said platforms for online advertising. Using Google Maps to find their way when they travel and finding out the immediate road and traffic conditions with digital banners around the road, has obviously led to a boom in advertising and marketing. Recently, internet users have increasingly desired to immerse themselves in a Metaverse-like platform where they can interact and socialize. Meta’s Metaverse is a tightly connected network of 3D digital spaces that allow users to escape into a virtual world. It is designed to change the way you socialize, work, shop, and connect with the real and virtual world around you. These platforms are not fully submerged in the real world; they are inclined toward virtual spaces only, making it obvious to fill this gap. Thus, the proposed framework in this chapter would be a new kind of system that may develop a socio-meta platform, powered by augmented reality and other technologies like photogrammetry and LiDAR. Augmented reality provides an interactive way of experiencing the real world, where the objects of the natural world are enhanced by computer-generated perceptual vision. One of the significant problems with augmented reality is the process of building virtual 3D objects that can be augmented into real spaces, which could be solved with photogrammetry and LiDAR. Photogrammetry is the technique of producing 3D objects using 2D images of a physical object taken from different angles and orientations. LiDAR, on the other hand, is another 3D reconstruction technology used widely by Apple’s eco-system. The functioning of LIDAR is very similar to sonar and radar, and the detection and ranging part are where it stands out from the others. The idea behind this platform is to open tons of virtual dimensions in the real world using the principles of mixed reality and geographic mapping tools such as Google Maps, MapBox, and GeoJSON; it would consequently transition the way people spend their time on social media by opening a portal for generating 3D objects that can be augmented to the real-world location using photogrammetry and cloud anchors by just a few 2D digital photographs taken from their camera.

E-commerce platforms face the challenge of enabling customers to assess the utility of products in their intended environments, particularly in the home furniture sector. Augmented Reality (AR) presents a promising solution, with major companies like IKEA, Wayfair, and Overstock introducing AR applications. Nevertheless, a significant knowledge gap exists, prompting this research to delve into this void and scrutinize the economic value of AR in shaping consumers' Willingness to Pay (WTP) in the context of online auctions. This dissertation comprises three interconnected papers that collectively scrutinize the multifaceted impacts of AR on consumers' WTP in the specific realm of online auctions. The first paper investigates the influence of Augmented Reality (AR) in mobile e-commerce on consumers' perceived risks and WTP in online auctions. Grounded in perceived risk theory, the study addresses Perceived Psychological Risk, Perceived Social Risk, and Perceived Performance Risk. An online experiment involving 61 participants compared AR mobile e-commerce with a 3D mobile e-commerce interface, and data analysis utilized SPSS and Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings indicate that AR Mobile E-commerce significantly reduces perceived social risk, positively affecting WPT. However, AR in Mobile E-commerce does not substantially mitigate perceived psychological risk, and this risk dimension does not significantly affect WPT. Similarly, AR in Mobile E-commerce positively influences the reduction of perceived performance risk, but this risk dimension does not significantly influence WPT. Mediation analysis suggests that perceived social risk plays a crucial role as a mediator between AR in Mobile E-commerce and consumers' WPT. The second paper explores the impact of AR on consumers' WTP in an online auction context within mobile e-commerce, drawing on the experiential hierarchy model (EHM). The study posits that AR positively influences consumers' WTP compared to 3D product displays, triggering affective (enjoyment) and cognitive (perceived ownership and perceived product quality) responses, which subsequently influence behavioral responses (willingness to pay more). Analysis of 61 valid responses through PLS-SEM and SPSS 29 reveals that AR significantly enhances consumers' perceived enjoyment and perceived product quality, positively impacting their willingness to pay. However, perceived ownership does not directly affect willingness to pay. Demographic factors such as age, gender, purchase frequency, and income do not have a direct influence. Mediation analysis suggests that perceived enjoyment, perceived product quality, and perceived ownership do not significantly mediate the relationship between AR and WTP. The third paper addresses the lack of standardized AR application guidelines for e-commerce. Using sentiment analysis of 1,049 user reviews of the IKEA Place App, this study reveals predominant dissatisfaction with the app, leading to the development of a comprehensive set of AR mobile e-commerce design guidelines. The research also compares AR mobile e-commerce with traditional 3D versions, finding a statistically significant difference in usability, with the AR version considered more usable. However, there was no significant correlation between usability scores and participants' willingness to pay on both platforms. This study sheds light on AR's potential and challenges in e-commerce, offering insights into enhancing user experience and economic outcomes. In conclusion, this dissertation contributes to the understanding of how AR impacts consumers' WTP in the context of online auctions within e-commerce, addressing perceived risks, experiential responses, and design guidelines. These findings offer valuable insights for e-commerce businesses seeking to harness AR's potential to enhance the shopping experience and drive revenue growth.

This study is about the new expressive techniques for promotional videos for culture contents and aims to propose a new design model for making effective promotional videos using augmented reality technology and E-museum concepts. Augmented reality is one of the up-rising intelligent information technology, but has been barely used for promotional videos. However the technology enables the interaction between physical objects in the real world and virtual image though digital devices. Augmented reality opens the door for connecting real and virtual world, and invites humans to the virtual environment. There are growing numbers attempt to move off-line culture contents into on-line space. Considering the connection between culture contents and digital environment, more studies about the convergence is necessary in the cultural-art industry, especially for marketing business. Therefore, this study aims to take a brief look at augmented reality technology, and proposes the new experimental model and expressive techniques for cultural-art organizations’ promotional video, which set the experiential learning environment, and enables consumers to take contents actively.

Large companies use a lot of resources on workshop operator training and industrial machinery maintenance since the lack of this practice or its poor implementation increases the cost and risks of operating and handling sensitive and/or hazardous machinery. Industrial Augmented Reality (IAR), a major technology in the Industry 4.0 paradigm that may enhance worker performance, minimize hazards and improve manufacturing processes, could be beneficial in this situation. This paper presents an IAR solution that allows for visualizing and interacting with the digital twin of a critical system. Specifically, the augmented digital twin of an industrial cooler was developed. The proposed IAR system provides a dynamic way to perform operator training with a full-size model of the actual equipment and to provide step-by-step guidance so that maintenance processes can be performed more safely and efficiently. The proposed system also allows several users to use devices at the same time, creating a new type of collaborative interaction by viewing the model in the same place and state. Performance tests with many simultaneous users have been conducted, with response latency being measured as the number of connected users grows. Furthermore, the suggested IAR system has been thoroughly tested in a real-world industrial environment.

The perceptual behavior of consumers on a product displayed in the market has a vital role in analyzing the importance given to that product. Therefore, various strategies have been developed to understand this consumer behavior in the selection of products. Immersive technologies like virtual, augmented, and mixed reality are among them. With the foremost feature of immersion in the virtual world and interaction of users with virtual objects, virtual reality, and augmented reality have unlocked their potential in research and a user-friendly tool for analyzing consumer behavior. In addition to these technologies, mixed reality also has a significant role in investigating consumer behavior. Studies on immersive technologies in food applications are vast, hence this review focuses on the applications of virtual, augmented, and mixed reality in the food selection behavior of consumers. The behavioral studies are elicited to develop new products based on consumer needs, to understand the shopping behavior in supermarkets for real-time usage, and to know the influence of emotions in a selection of products. The findings suggest that virtual, augmented, and mixed reality induce immersion of the users in food selection behavioral studies. Information on the technological advancements in the tools used for bringing immersion and interaction are discussed for its futuristic applications in food. Though immersive technology gives users a realistic virtual environment experience, its application in food systems is in the budding stage. More research on human response studies would contribute to its innovative and inevitable application in the future.

Augmented Reality Systems (ARS) attempt to enhance humans’ perception of their indoors and outdoors working and living environments and understanding of tasks that they need to carry out. The enhancement is effected by complementing the human senses with virtual input. For example, when the human visual sense is enhanced, an ARS allows virtual objects to be superimposed on a real world by projecting the virtual objects onto real objects. This provides the human user of the ARS with additional information that he/she could not perceive with his/her senses. In order to receive the virtual input and sense the world around them augmented with real time computer-generated features, users of an ARS need to wear special equipment, such as head-mounted devices or wearable computing gears. Tracking technologies are very important in an ARS and, in fact, constitute one challenging research and development topic. Tracking technologies involve both hardware and software issues, but in this chapter we focus on tracking computation. Tracking computation refers to the problem of estimating the position and orientation of the ARS user’s viewpoint, assuming the user to carry a wearable camera. Tracking computation is crucial in order to display the composed images properly and maintain correct registration of real and virtual worlds. This tracking problem has recently become a highly active area of research in ARS. Indeed, in recent years, several approaches to vision-based tracking using a wearable camera have been proposed, that can be classified into two main categories, namely “marker-based tracking” and “marker-less tracking.” In this chapter, we provide a concise introduction to vision-based tracking for mobile ARS and present an overview of the most popular approaches recently developed in this research area. We also present several practical examples illustrating how to conceive and to evaluate such systems.

In recent years, hardware and software advances in digital technology have prompted not only the commercial use of augmented reality (AR) systems, but its implementation in education. Marker-based AR systems allow users to input pre-designed markers, and generate new scenes blending together the real world and computer-generated 3D images. Nevertheless, few AR systems permit simultaneous interactions of multiple markers. This study aims to construct an interactive multimedia learning system. The story script showcases the growth of flowers by applying a series of markers, where interactions with 3D objects can be achieved through AR technology. Learners can use a camera to capture the information of multiple AR markers, and 3D objects and media can be generated on-screen. With variations in AR markers, and time changes of the Arduino Clock, one can learn the growth of plants during day and night through a mixed-reality virtual experience that brings fun to learning. Accordingly, this e-learning system is capable of boosting students' learning interests and improving their learning effectiveness.
