Augmented Virtual Reality: Combining Crowd Sensing and Social Data Mining with Large-Scale Simulation Using Mobile Agents for Future Smart Cities

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

Smart mobile devices are fundamental date sources for crowd activity tracing. Large-scale mobile networks and the Internet-of-Things (IoT) expand and become part of perva-sive and ubiquitous computing offering distributed and trans-parent services. With the IoT, Crowd Sensing is extended by Things Sensing, creating heterogeneous smart environments. A unified and common data processing and communication methodology is required so that the IoT, mobile networks, and Cloud-based environments seamlessly integrate, which can be fulfilled by self-organizing mobile agents, discussed in this work. Currently, portability, resource constraints, security, and scalability of Agent Processing Platforms (APP) are essen-tial issues for the deployment of Multi-agent Systems (MAS) in highly heterogeneous networks. Beside the operational aspects of MAS, an organizational structure is required for the deployment of MAS in crowd sensing and social mining applications. The Planetary Nervous system (Nervousnet) consists of virtual sensors building the core functionality for such applica-tions running on smart phones with a Cloud-like architecture. The virtual sensors enable a holistic composition and modelling approach. Self-organizing and adaptive mobile agents are well known as the core cells of holistic and modular systems. In this work, both concepts are combined. JavaScript agents are introduced as virtual sensors in the Nervousnet environment, evaluated with a simulation of a distributed sensor fusion use-case in a mobile network based on real-world data from Nerv-ousnet, showing the suitability of the hybrid approach, benefit-ing from local and event-based sensor processing performed by the MAS.

Metaverse + Realverse: In Search Of Harmony

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.

As important achievements of modern science and technology, augmented reality (AR) and virtual reality (VR) technologies have shown great application potential in the field of education. They provide rich interactive experiences and teaching resources for the learning process in different ways. AR technology provides a new perspective for education by superimposing virtual information on the real world. For example, in history classes, students can use AR technology to see 3D models of historical figures in textbooks or observe the re-enactment of historical events. In science education, AR can help students visualize complex molecular structures or the internal structure of organisms, making abstract knowledge concrete and intuitive. VR technology allows users to immerse themselves in the virtual world by building a completely virtual environment. In education, VR technology can simulate a real experimental environment, allowing students to conduct virtual experiments, or let students explore in virtual historical scenes and experience immersive historical education. This paper discusses the differences between AR and VR in learning, focusing on their application in history, medicine, music, physics and physical education. By analyzing the performance in terms of content delivery and interactivity in detail, the study found that AR has clear advantages in real-world applications, while VR is more attractive in immersive and simulation-based learning. The article summarizes the best application scenarios of each technology in different disciplines, based on the support of the cited literature.

Augmented and virtual reality have the potential to improve various aspects of everyday life such as tourism. An elementary part of tourism is the organization and execution of guided city tours. In case of tours for virtual cities, such as in the case of no longer existing ancient settlements, a combination of augmented and virtual reality may render high benefit for collaboration between guide and visitors. Immersive technology has been shown suitable for collaborative systems by previous research, as they can provide a better experience than other technologies. However, recent literature analyses showed that there is a lack of research regarding the role of augmented reality supporting the active/leading user role in such scenarios. Usually, augmented reality is used for the users who are passively experiencing the virtual environment and not for the one controlling it. However, we think that augmented reality has a large potential to improve the workflow of such a primary user. To investigate this research question, we present a collaborative system in this work, which implements a virtual city tour. In this system, the guide is using augmented reality and the visitor is immersed in the virtual city using virtual reality glasses. To implement a valid research prototype, the system has been developed in close feedback with experts in the field of guided city tours.

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.

Reality check

Mixed reality enables users to immerse themselves in high-workload interaction spaces like office work scenarios. We envision physiologically adaptive systems that can move users into different mixed reality manifestations, to improve their focus on the primary task. However, it is unclear which manifestation is most conducive for high productivity and engagement. In this work, we evaluate whether physiological indicators for engagement can be discriminated for different manifestations. For this, we engaged participants in a typing task in three different mixed reality manifestations (augmented reality, augmented virtuality, virtual reality) and monitored physiological correlates (EEG, ECG, and eye tracking) of users' engagement and workload. We found that users achieved best typing performances in augmented reality and augmented virtuality. At the same time, physiological engagement peaked in augmented virtuality, while workload decreased. We conclude that augmented virtuality strikes a good balance between the different manifestations, as it facilitates displaying the physical keyboard for improved typing performance and, at the same time, allows one to block out the real world, removing many real-world distractors.

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.

Information media continues to evolve with the advancement of time. It is needed at all times because through information media, people can access various types of current and emerging information, as well as exchange ideas and interact with one another. Numerous technologies have been developed to support the dissemination of information, one of which is Augmented Reality (AR). Augmented Reality (AR) can be defined as an environment that merges two realms: the virtual world and the real world. AR allows information to be embedded into the virtual world and displayed in the real-world using markers or barcodes via smartphones or other devices. Augmented Reality (AR) has been widely implemented across various sectors, one of which is promotional media. In the business world, AR can serve as a powerful promotional tool. Therefore, with the advancement of Augmented Reality (AR) technology, a promotional media application was developed using AR for the housing brochures of Cipta Bangun Khatulistiwa Ltd. This AR-based promotional media is expected to assist current and prospective consumers in gaining a more realistic view of Cipta Bangun Khatulistiwa Ltd. housing details through specially designed brochures, without the need to travel to the development site, which is relatively far from the city center. From the results of the system test, 80% mastery and very good assessment were obtained.

In this poster abstract we describe an experiment that measured depth judgments in optical see-through augmented reality at near-field distances of 34 to 50 centimeters. The experiment compared two depth judgment tasks: perceptual matching, a closed-loop task, and blind reaching, a visually open-loop task. The experiment tested each of these tasks in both a real-world environment and an augmented reality environment, and used a between-subjects design that included 40 participants. The experiment found that matching judgments were very accurate in the real world, with errors on the order of millimeters and very little variance. In contrast, matching judgments in augmented reality showed a linear trend of increasing overestimation with increasing distance, with a mean overestimation of ~1 cm. With reaching judgments participants underestimated ~4.5 cm in both augmented reality and the real world. We also discovered and solved a calibration problem that arises at near-field distances.
