Model-Based Product Configuration in Augmented Reality Applications

Creating a layout for an augmented reality (AR) application which embeds virtual objects in a physical environment is difficult as it must adapt to any physical space. We propose a rule-based framework for generating object layouts for AR applications. Under our framework, the developer of an AR application specifies a set of rules (constraints) which enforce self-consistency (rules regarding the inter-relationships of application components) and scene-consistency (application components are consistent with the physical environment they are placed in). When a user enters a new environment, we create, in real-time, a layout for the application, which is consistent with the defined constraints (as much as possible). We find the optimal configurations for each object by solving a constraint-satisfaction problem. Our stochastic move making algorithm is domain-aware, and allows us to efficiently converge to a solution for most rule-sets. In the paper we demonstrate several augmented reality applications that automatically adapt to different rooms and changing circumstances in each room.

There is a growing interest for the broad use of Augmented Reality (AR) and Virtual Reality (VR) in the fields of bioinformatics and cheminformatics to visualize complex biological and chemical structures. AR and VR technologies allow for stunning and immersive experiences, offering untapped opportunities for both research and education purposes. However, preparing 3D models ready to use for AR and VR is time-consuming and requires a technical expertise that severely limits the development of new contents of potential interest for structural biologists, medicinal chemists, molecular modellers and teachers. Herein we present the RealityConvert software tool and associated website, which allow users to easily convert molecular objects to high quality 3D models directly compatible for AR and VR applications. For chemical structures, in addition to the 3D model generation, RealityConvert also generates image trackers, useful to universally call and anchor that particular 3D model when used in AR applications. The ultimate goal of RealityConvert is to facilitate and boost the development and accessibility of AR and VR contents for bioinformatics and cheminformatics applications. http://www.realityconvert.com. dfourch@ncsu.edu.

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.

Methods involve AR content creation, user testing, and data analysis. Overall, findings suggest that the AR application effectively meets visitors' learning needs and enhances the educational value of museum exhibits by providing unique AR features. The significance of the project lies in its potential to transform cultural heritage tourism by bridging the gap between traditional museum experiences and digital engagement. The study also serves as a preliminary investigation to guide the future development and deployment of AR applications within the museum setting.

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

This study investigates the benefits of augmented reality (AR) in the tourism industry and its impact on data security. The background of the research highlights that information technology is becoming increasingly important in the tourism industry, with augmented reality (AR) being a major focus for enhancing visitor experiences. In this context, concerns about user data protection arise since AR applications may require personal information such as user location and travel preferences. A comparative research method was used to compare two popular augmented reality (AR) applications: Smartify, Arts and Culture, Zome, Augmented Reality, Maps AR, Guideo, and AR Trial. The results indicate that most applications have adequate data security policies, including data transfer encryption and user control over their data. Zome was found to be the best in terms of data security and user privacy, scoring 90% in the assessment. This research underscores the importance of using AR applications to maintain data security and user privacy in the tourism industry and suggests further research to learn more about the data privacy practices of AR applications.

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.

This research focuses on the production and creation of educational materials for Arabic vocabulary learning using Augmented Reality Technology, namely ARabic-Kafa, which can support both teachers and students. The Marker Based Tracking tool is used in this Augmented Reality application. This method was employed because it can read objects and then display 3-dimensional (3D) virtual objects. The first step in resolving this issue is to create animations through the blender application, choose the image to be utilised as a Marker, and finally, export it to Vuforia to form an Augmented Reality app. The mobile app of Augmented Reality-based educational media is the product of this research. A series of testing were employed and a minimum distance for displaying a 3D object is 10 cm, and the minimum angle 30° to 90° to view 3D objects. The rotation marker's output effectively shows every aspect of the 3D object. Furthermore, the audio pronunciations can be played effortlessly.

With Generation Z becoming the primary group of nursing learners and the increasing shortage of nursing education resources, augmented reality and mixed reality based on head-mounted displays are being used more and more in nursing education. However, the current application landscape and the proper usage of these concepts remain unclear. Therefore, this study aims to conduct a scoping review to explore the current applications of head-mounted display-based augmented reality and mixed reality in nursing education and to clarify the definitions and usage of the concepts of augmented reality and mixed reality, ultimately providing directions for future applications and research. Based on the five-stage framework and PRISMA-ScR guidelines, a comprehensive collection and summarization of evidence regarding the application of head-mounted display-based augmented reality and mixed reality in nursing education were conducted. The databases retrieved include CNKI, Wanfang Database, VIP, CBM, PubMed, Cochrane Library, Embase, CINAHL, Web of Science, Scopus, IEEE Xplore, ACM Digital Library, and Ei. The languages of the included literature are Chinese and English. The retrieval was up to October 2024. A total of 44 studies were included in this review, covering three types of head-mounted displays: immersive head-mounted displays, smart glasses, and smartphone-based head-mounted displays. The main application areas were skills training and knowledge acquisition. Most of the studies were feasibility studies, though they also included some efficacy studies and research on personal experiences. In addition, these studies often employed vague or inconsistent definitions of augmented reality and mixed reality. Despite various explorations in the application of head-mounted display-based augmented reality and mixed reality in nursing education, there is still room for improvement in the relevant theory and utilization of this technology. In the future, interventions should use the three dimensions (observation of reality, real - virtual interaction, and fidelity of virtuality) described in detail, rather than simply employing the concepts of augmented reality or mixed reality. Efforts should be concentrated on developing and implementing head-mounted displays combined with other technologies that boast enhanced performance and cost - effectiveness, and further validating their effectiveness.

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.
