Virtual Reality & Augmented Reality in Industry

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

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.

This study presents the development and evaluation of ARTechGuide, an Augmented Reality (AR)-based application designed for technical training of operators in an automotive industrial environment. The research was conducted using the Design Science Research (DSR) methodology, with application and validation in a real factory setting. The system uses mobile devices and visual recognition to provide audiovisual instructions in five critical operational scenarios. Compared to traditional methods, a 57 % reduction in setup time, a 25 % increase in execution accuracy, and a 75 % decrease in requests for help were observed. The system achieved an average of 9.25 on the User Experience (UX) scale and 4.5 on nine technical indicators evaluated by experts. Unlike commercial AR platforms, the solution adopts a local architecture, independent of constant connectivity, facilitating its adoption in environments with operational constraints. These benefits are aligned with the Industry 5.0 proposal, which values customization according to human needs.

The quest for finding the killer application for Industrial Augmented Reality(IAR) is still active. The existing solutions are ingenious but most can not be directly integrated with the existing industrial workflows. Generally, IAR applications require modifications in the industrial workflows depending on the tracking methodology. These modifications end up being an overhead for the users and deter them from using AR solutions. In this poster we propose a resourceful solution to achieve end-to-end workflow integration with minimum effort from the user end. The solution is suited for laser guided Spatial Augmented Reality(SAR) systems mainly preferred for industrial manufacturing applications. We also introduce a new concept for pose computation, which is inspired from existing mechanical concept of part alignment. The accuracy of our method is comparable to the classical marker based methods. The complete process of pose computation, from initialisation to refinement, is designed to be plug and play.

Supporting maintenance with 3D object enhanced instruction is one of the key applications of Augmented Reality (AR) in industry. For the breakthrough of AR in maintenance, it is important that the technicians themselves can create AR-instructions and perform the challenging task of placing 3D objects as they know best how to perform a task and what necessary information needs to be displayed. For this challenge, a 3D-content editor is being presented wherein a first step the 3D objects can roughly be placed using a 2D image of the machine, therefore, limiting the time required to access the machine. In a second step, the positions of the 3D objects can be fine-tuned at the machine site using live footage. The key challenges were to develop an easily accessible UI that requires no prior knowledge of AR content creation in a tool that works both with live footage and images and is usable with a touch screen and keyboard/mouse. The 3D-content editor was qualitatively assessed by technicians revealing its general applicability, but also the requirement for a lot of time to gain the necessary experience for positioning 3D objects.

Through technological progress during recent years, Augmented Reality (AR) technology can be used on ordinary smartphones with applications (Apps) in many formal and informal learning environments and educational institutions (e.g. [1, 2]). It is emerging as a suitable technology for teaching psychomotor skills. Simultaneously, gamification has become increasingly popular in the teaching field, providing famous examples, such as Duolingo (for the acquisition of foreign languages) or Codecademy (for learning programming languages) [3]. Many papers have already highlighted the beneficial aspects of gamification and AR for education and teaching (e.g. [1, 2, 4, 5]. While gamification is useful for improving students’ motivation and engagement, AR can be applied to teach them operational skills without any time, costs and place constraints. Hence, this opens up numerous possibilities and forms to combine these two aspects (AR and gamification) for higher education teaching. However, there has been less research focusing on how gamification and AR can be combined in a useful manner to keep up students’ initial motivation aroused through novelty effects of AR learning environments. Accordingly, this paper will present such a gamification concept for an AR based virtual preparation laboratory training to overcome the risk of demotivation, once AR will settle as a mainstream technology such as learning videos. The focus of the AR-App – presently being developed at the University of Paderborn – is to remedy the students’ lack of practical skills when operating electro-technical laboratory equipment during their compulsory laboratory training.

Rapid development in processing power, graphic cards and mobile computers open up a wide domain for Mixed Reality applications. Thereby the Mixed Reality continuum covers the complete spectrum from Virtual Reality using immersive projection technology to Augmented Reality using mobile systems like Smartphones and UMPCs. At the Fraunhofer IGD the Mixed Reality Framework instantreality (www.instantreality. org) has been developed as a single and consistent interface for AR/VR developers. This framework provides a comprehensive set of features to support classic Virtual Reality (VR) as well as mobile Augmented Reality (AR). The goal is to provide a very simple application interface which includes the latest research results in the fields of high-realistic rendering, 3D user interaction and total-immersive display technology. The system design is based on various industry standards to facilitate application development and deployment.

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 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.

Technologies such as Virtual and Augmented Reality have gained popularity lately. Because of their convenience and accessibility, these technologies have been adopted in various domains. Virtual reality and augmented reality create an immersive experience, enabling 3D visualization of the content. This technology lets you visualize data from different sensors at the same time, overlaying relevant and helpful information over your environment through a headset. In this article, we give a perspective on these technologies from a biomedical engineering standpoint. In this article, we discuss the various technologies of current biomedical engineering. These technologies allow us to move beyond traditional 2D images towards 3D models that can be made visible and manipulated with Augmented and Virtual Reality. The basic applications of biomedical engineering include representation of mechanisms in space and time dimensions and three-dimensional visualizations of difficult structures in anatomy. The article is an attempt to bring the latest results on the benefits of virtual and augmented reality in biomedical engineering.

Computational thinking (CT) skills are increasingly important in education to prepare students for the challenges of the digital age. Augmented Reality (AR) and Virtual Reality (VR) have been introduced as immersive technologies that have the potential to enhance CT skills through more interactive learning experiences. However, there is still a gap in understanding the effectiveness of these technologies in supporting the development of CT, particularly in different levels of education and disciplines. Although several studies have highlighted the benefits of AR and VR in education, no systematic review integrates these findings to identify advantages, challenges, and opportunities for further implementation. Therefore, this study conducted a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by analyzing 25 empirical studies (AR=17, VR=8) obtained from the Scopus database (2008-2024). The analysis addresses four key research questions: (1) the current state of AR/VR in CT development, (2) their advantages, (3) implementation challenges, and (4) future research directions. The results show that AR is more widespread than VR at various levels of education, with dominance in higher education followed by secondary and primary schools. Computer science is the main field of application of AR and VR, while AR is also widely applied in mathematics to increase interest and problem-solving. A total of 11 studies reported significant impacts of these technologies on CT, with AR being superior in increasing student motivation and engagement, as well as aiding in problem-solving and debugging. In contrast, VR provides a more immersive learning experience by strengthening concept understanding, especially in programming and recursion. However, several obstacles in the application of AR and VR, such as hardware limitations, costs, and user skills, affect the effectiveness of these technologies in the learning environment. This study also identified potential future research, including the exploration of VR in primary and kindergarten education, the application of VR in non-computer science fields, and the efficient use of these technologies in supporting the CT process. This study provides more precise insights into the optimal ways of utilizing AR and VR in developing CT skills. It is a reference for educators, policymakers, and researchers in supporting CT learning.
