Three-layer polarisation volume grating with enhanced diffraction efficiency and FOV in AR and VR applications

ABSTRACT In the rapidly evolving fields of Augmented Reality (AR) and Virtual Reality (VR), achieving high diffraction efficiency and a wide field of view (FOV) is critical for enhancing visual experience. This paper presents a three-layer Polarisation Volume Grating (TL-PVG) structure designed to address the limitations of single-layer PVGs in AR/VR applications. By stacking multiple PVG layers with different tilt angles, TL-PVG achieves an expanded angular bandwidth and improved diffraction efficiency, enabling brighter and more immersive displays. The proposed TL-PVG structure incorporates polarisation multiplexing to optimise the optical diffraction efficiency by approximately 75%, thereby enhancing image brightness and sharpness. The experimental results demonstrate that TL-PVG significantly outperforms traditional single-layer PVGs, offering a promising solution for waveguide elements in next-generation AR/VR displays. This study provides a comprehensive analysis of the fabrication process, optical properties, and applications of TL-PVGs, highlighting their potential to revolutionise the AR/VR technology.

Moving objects detection based on histogram of oriented gradient algorithm chip for hazy environment

<span>The most important aspects of computer vision are moving object detection (MOD) and tracking. Many signal-processing applications use regional image statistics. Compute-intensive video and image processing with low latency and high throughput is done with field programmable gate array (FPGA) image processing. Local image statistics are used for edge identification and filtering. The histogram of oriented gradients (HoG) algorithm extracts local shape characteristics by equalizing histograms. The objective of the work is to design the hardware chip of the algorithm and perform the simulation in the Xilinx ISE 14.7 simulation environment. The performance of the chip is evaluated in Modelsim 10.0 simulation software to check its feasibility. The performance of the chip design is estimated on Viretx-5 FPGA and compared with the MATLAB-2020 image processing tool-based response time. This form of tracking typically deals with identifying, anchoring, and tracking images and videos. A mask made from a cut-out of the object can then determine the plane's coordinates depending on its position. This type of object tracking is frequently utilized in the field of augmented reality (AR). The algorithm is most suited for object detection using hardware controllers in haze and foggy environments.</span>

PesRec: A parametric estimation method for indoor semantic scene reconstruction from a single image

Reconstructing semantic indoor scenes is a challenging task in augmented and virtual reality. The quality of scene reconstruction is limited by the complexity and occlusion of indoor scenes. This is due to the difficulty in estimating the spatial structure of the scene and insufficient learning for object location inference. To address these challenges, we have developed PesRec, an end-to-end multi-task scene reconstruction network for parameterizing indoor semantic information. PesRec incorporates a newly designed spatial layout estimator and a 3D object detector to effectively learn scene parameter features from RGB images. We modify an object mesh generator to enhance the robustness of reconstructing indoor occluded objects through point cloud optimization in PesRec. Using the analyzed scene parameters and spatial structure, the proposed PesRec reconstructs an indoor scene by placing object meshes scaled to 3D detection boxes in an estimated layout cuboid. Extensive experiments on two benchmark datasets demonstrate that PesRec performs exceptionally well for object reconstruction with an average chamfer distance of 5.24 × 10-3 on the Pix3D dataset including 53.61 % mAP for 3D object detection and 79.7 % 3D IoU for the estimation of layout on the commonly-used SUN RGB-D datasets. The proposed computing network breaks through the limitations caused by complex indoor scenes and occlusions, showing optimization results that improve the quality of reconstruction in the fields of augmented reality and virtual reality.

Design of elemental-image-predistortion and splicing seamless integral near-eye display based on aspherical microlens arrays

The near-eye display (NED) has long been a challenging and intriguing research focus in the fields of augmented reality (AR) and virtual reality (VR). In this paper, we propose a design method of elemental-image (EI) predistortion and splicing seamless integral NED based on microlens arrays (MLAs), which combines rigorous optical design with image preprocessing. The construction of MLA is based on sub-channel optimization and splicing, enabling the realization of both VR-NED and AR-NED. The calibration of each sub-channel in NED is conducted using a perfect lens that possesses an effective focal length equivalent to that of the human eye. To achieve a high-precision seamless integral NED, the precise location and acquisition of initial EIs are accomplished through chief ray tracing and image clipping. The predistortion EI array (EIA) is further obtained by combining chief ray tracing and radial basis function (RBF) image warping techniques. A seamless MLA-based integral AR-NED with a full field of view (FOV) of 60° is realized and verified. A prototype of a seamless MLA-based integral VR-NED is further implemented by integrating multiple discrete single-focal predistortion EIAs. The effectiveness of the proposed method has been validated through illumination and luminance simulations as well as experiments.

The use of augmented reality applied to museums to preserve and communicate cultural heritage sustainably is a topic of increasing relevance today. Museums play an essential role in preserving and disseminating culture and history, and augmented reality has emerged as a powerful technological tool to enrich the visitor experience and ensure the sustainable preservation of cultural heritage. The fundamental objective of this literature review is to explore and understand the key contributions that are being made in the field of augmented reality applied to museums, with a focus on sustainability. The literature related to this topic is dispersed in various sources of information, which motivates the need to carry out a detailed and systematic analysis incorporating sustainability aspects. To carry out this analysis, the metaphor of the “tree of science” is used. This metaphor provides a structured approach that is applied in two complementary ways. Firstly, it focuses on collecting and analyzing scientometric statistics that cover data on countries, authors, academic institutions, and research centers involved in developing augmented reality applications for museums with sustainable methodologies. This quantitative perspective offers a global view of the contributions and their geographical scope including their sustainability impact. Secondly, an evolutionary analysis based on the “tree of science” is carried out. This historical approach examines the origin and evolution of contributions in the field of augmented reality applied to museums, from its first manifestations to the most recent innovations, with an emphasis on sustainable practices. This historical approach is essential to understanding the trajectory and development of augmented reality applications in the museum context and their role in promoting sustainable cultural heritage preservation. This review aims to provide a complete and contextualized view of the use of augmented reality in museums for the sustainable preservation and communication of cultural heritage. Through a multidimensional approach encompassing scientometric statistics and historical analysis, we seek to shed light on this technology’s most significant contributions and evolution in the museum sector, with a particular focus on sustainability.

An Augmented Reality Interface for Safer Human-Robot Interaction in Manufacturing

With the adaptation of Industry 4.0 and emerging ideas of Industry 5.0, the manufacturing industry is shifting back towards human-centered production. In these scenarios, collaboration robots (Cobots) become an important part of this shift toward human-robot collaboration (HRC). However, with the introduction of robots meant to work in close proximity to and in collaboration with people, problems of safety and collaboration efficiency arise. On the other hand, there are developments in the field of Augmented Reality (AR), which allow overlaying digital information onto the physical environment and having people interact with it. This paper introduces an AR interface for HRC with cobots, which can tackle the issues of human safety and efficiency. The use of the interface is demonstrated on an HRC ski assembly use case.

Minimal machines: augmented reality for filament-construction of partially ordered systems in architecture

Wearable augmented reality-supported technology allows for tracking and informing the interrelation of craftspeople with the architectural structure they are working on. Especially when dealing with partially ordered rather than fully ordered material systems, this feedback is relevant since toolpaths cannot be established a priori but rather evolve during the architectural construction process itself. On the one hand, partially ordered material systems have the potential of adapting to conditions both internal and external to the structure. On the other hand, they can be considered as structures that are constantly evolving: instead of demolishing a building, it could be continuously repaired. While a large range of investigations involve robots equipped with sensory feedback to address this topic, only few studies have attempted to equip humans with a minimal amount of technology so as to harness human sensory intelligence, merely enhancing it with technology. This article introduces the current state of the field of augmented reality and partially ordered systems in architectural construction with a focus on filament-laying processes. Then, it presents a newly developed framework for augmented construction with designed filaments for partially ordered fabrics in architecture, encompassing both the wearable hardware and the custom-developed software. The principles of systems in human-made filament-based architecture are introduced and set in relation to similar role model systems in animal-made architecture. Then, three experiments of increasing complexity investigate the human-to-machine, the machine-to-human and the machine-to-human-to-machine communication. A final integrative demonstrator serves to investigate the framework for augmented reality in construction on a full architectural scale. As an outlook, areas of further research—such as the integration of artificial intelligence into the feedback loop—are discussed.

AR Indoor Navigation System

Abstract: Nowadays, the field of abstract- augmented reality is starting to boom. In business, education, and now in the navigation of enormous multi-complexes, augmented reality is utilized. With its many capabilities and fewer hardware requirements at the same time, augmented reality makes work simpler and more exciting. When utilized for navigation, augmented reality can give a person additional directions from where they are now to where they want to go in an unknown environment. The purpose ofour research is to investigate every technology that is practical for indoor navigation and to propose a simple prototype as a remedy. Augmented Reality employs its inherent properties toassess a person's position and provide the appropriate navigational guidance in the case of indoor navigation.

Hand-Controlled User Interfacing for Head-Mounted Augmented Reality Learning Environments

With the rapid expansion of technology and hardware availability within the field of Augmented Reality, building and deploying Augmented Reality learning environments has become more logistically viable than ever before. In this paper, we focus on the development of a new mobile learning experience for a museum by combining multiple technologies to provide additional Human–computer interaction possibilities. This is both to reduce barriers to entry for end-users as well as provide natural interaction methods. Using our method, we implemented a new approach to gesture-based interactions for Augmented Reality interactions by combining two devices, a Leap Motion and a Microsoft HoloLens (1st Generation), via an intermediary device with the use of local-area networking. This was carried out with the intention of comparing this method against alternative forms of Augmented Reality to determine which implementation has the largest impact on adult learners’ ability to retain information. A control group has been used to establish data on memory retention without the use of Augmented Reality technology, along with three focus groups to explore the different methods and locations. Results found that adult learners retain the most overall information when being educated through a traditional lecture, with a statistically significant difference between the methods; however, the use of Augmented Reality resulted in a slower rate of knowledge decay between testing intervals. This contrasts with existing research as adult learners did not respond to the technology in the same way that child and teenage audiences previously have, which suggests that prior research may not be generalisable to all audiences.

Chaotic microcomb inertia-free parallel ranging

The increasing demand for high pixel acquisition rates in the fields of augmented reality, autonomous driving, and robotics has led to a growing interest in solid-state beam scanning solutions that do not rely on moving parts. As a result, modern photonics has been driving the development of passive beam steering technology to meet these demands. Recently demonstrated imagers based on focal plane arrays, nanophotonic metasurfaces, and optical phased arrays have enabled unprecedented pixel resolutions and measurement speeds. However, the parallelization of >100 lasers and detectors, which has been successfully implemented in commercial time-of-flight sensors, has not been widely adopted for passive scanning approaches. In this work, we demonstrate both inertia-free and parallel light detection and ranging (LiDAR) with microresonator frequency combs. We use 40 independent channels of a continuously scanned microresonator frequency comb operated in the chaotic regime in combination with optical dispersive elements to perform random modulation LiDAR with 2D passive beam steering.

Global Publication Trends in Augmented Reality and Virtual Reality for Learning: The Last Twenty-One Years

Augmented reality (AR) and virtual reality (VR) provide new experiences in the digital and simulation worlds. While they are intended to stimulate users’ perception and senses in general, the two differ significantly. This study aimed to seek and analyze international publications on the trends, similarities, differences, advantages, and disadvantages of AR and VR for learning over the period 2001-2021. In this study, bibliometric analysis using VOSViewer with the help of MS Excel was utilized to visualize metadata obtained from Scopus. Publish or Perish software supported the data collection of this study, which included retrieving and analyzing academic citations. The findings show that the AR/VR has trend continued to rise over the years. The results showed that Denmark and India (based on country bibliographic pairs), Journal of Physics Conference Series (based on journal bibliographic pairs), Y. Zhou publications (2018) (based on bibliographic pairs of publications), and Archana M. (India) with Lars K. (Denmark) (based on author bibliographic pairs) have become the most influential in the field of augmented reality and virtual reality for learning. AR and VR are two technologies changing how people use screens, thus creating new and exciting interactive experiences. In the future, it is expected that further research related to AR/VR and even Mixed Reality (MR) will continue to develop along with technological advancement. However, pedagogical competence remains an essential key to learning.

Survey of indoor tracking systems using augmented reality

<p><span lang="EN-US">Augmented reality overlays virtual content on the physical world, displaying location-based information more efficiently. Tracking is a trace detail of the location recorded, either by taking a reading based on a set time interval, set distance, and change in direction by more than a certain angle, or a combination of these. Tracking is divided into two types, outdoor tracking, and indoor tracking. Augmented reality added value and information to tracking applications, whether indoor or outdoor. Recently, outdoor tracking by the global positioning system (GPS) became an essential component in navigation applications. However, indoor tracking is still challenging in the augmented reality field. Most augmented reality indoor tracking use optical and sensor-based tracking, such as markers, beacons, Raspberry Pi, and route planner modules for the building. With the technology enhancement, indoor tracking started to rely on WiFi, Bluetooth, geographic information system, radiofrequency identification, and sensor chip technologies. Our paper describes the recent augmented reality tracking techniques from 2011 to 2021. The paper compares image detection algorithms with various communication technologies, disscusing the advantages and the limitations of each technology.</span></p>

An interdisciplinary Co-authorship networking perspective on AR and human behavior: Taking stock and moving ahead

The field of augmented reality (AR) and human behavior emerged when Azuma et al. (2001) refined the term augmented reality in 2001. Research on the topic has grown steadily in the past decade, yet there is a notable lack of consensus on humans' motivations and outcomes in interacting with AR. The present research takes a bibliographic approach to shed light on current research on AR in human-computer interaction and, using topic modeling, to identify and classify the topics that have drawn researchers’ interest. The results reveal three major topics of interest to researchers, namely “Education, Learning & Training Research”, “Marketing, Consumer Behavior & Business Research”, and “Digital Tourism & Cultural Heritage Research”. Drawing upon co-authorship theory, we identify prominent AR expert co-authorship networks that work on similar topics, yet also highlight that AR research is concentrated in a few research groups that publish articles with similar groups of authors and little outside their own networks. Together with AR experts from the four largest co-authorship networks, we highlight the common challenges that emerge in AR research, suggest solutions, and jointly propose a research agenda for AR and human behavior research.

The Integration of Augmented Reality (AR) in Education

New teaching techniques have been adopted as a result of the emergence of innovative technological tools in the field of Augmented Reality (AR), as investigated in several articles to date (Hsu 2017; Forsythe & Raine 2019). The availability of AR applications, both vision, and location-based, allows students today to learn foreign languages in a more contextualized and immersive manner, thanks to the use of smartphones and other electronic devices. Thus, this study seeks to analyze and review the recent trends in AR implementation in education and to present the main projects aimed at teaching with AR-based projects that have been published in the latest years in WOS and Scopus.
