Academia-industry Collaboration for Augmented Reality Application Development

Abstract Due to our previous experience in AR development, with this research project we propose to study how Augmented Reality (AR) can be adopted by an industrial partner and which are the major outcomes from which a company may benefit. For this purpose, we partnered with a forward-looking company willing to embrace the idea of implementing new technologies for industrial purposes. In this research we identified that the most significant impact which AR may have for our industrial partner is in providing remote assistance and for product exploitation and marketing purposes. For the latest we developed a customized AR application which is currently available on Apple’s App Store. By analysing the app analytics data, we found out that this application is a success in terms of marketing and not only. For the remote assistance AR app, we chose to use a commercial solution that can be adapted to fit our industrial partner’s needs. We also tested this application and found out that it greatly improves the communication between remote users thus dismissing the required assistance time.

Learning Performance Assessment using Mobile-Based Augmented Reality Application for Preschool Environment

However, most of the recent development in AR are mainly focusing on how to overcome hardware and software issues. It is undeniable that overcoming technical problems are crucial in AR development and rapid development for technology advancement; however, it neglects the end user. This study presents learning performance assessment using mobile-based augmented reality application for Malaysian preschool in rural areas. This study used non probability sampling and a paired t-test to compare the data collected from the sample test. The students showed a significant interest in learning using augmented reality technology

Development of Augmented Reality Applications for the Entire Spectrum of Screw Compressor Manufacturing Process

Augmented Reality (AR) in industrial applications connects users across digital and physical worlds and coupled with rapid return of investment, easy adoption, and as a meaningful way to stand out from the competition, AR is quickly becoming increasingly common in the industrial world. This paper first provides the reader with a description on what exactly is augmented reality and the difference between augmented reality and virtual reality, before moving onto describing the scope of this new application for an organisation like Howden. A brief analysis of how augmented reality is quickly finding a footing within this sphere is offered alongside an overview of the main players and actors. The paper then focuses on how the 3D CAD modelling already completed by the research and development, bare-shaft engineering and package engineering teams can be utilised in the rapid development of augmented reality applications. Examples of how Howden are developing and using these AR applications are then given with specific reference to the Screw sales teams using them to show prospective clients the model of their package / machine; the Screw package build teams sharing knowledge using AR during package fit-out and hazard and operability studies; the bare-shaft test team using AR within their acoustic enclosure and finally the impact of AR in the service teams. The paper concludes with how, as this technology becomes more mainstream, manufacturers adopting AR can significantly add value to their customers experience both in terms of service and satisfaction but also differentiate themselves from their competitors.

Preparing the HoloLens for user Studies: an Augmented Reality Interface for the Spatial Adjustment of Holographic Objects in 3D Indoor Environments

Augmented reality (AR), the extension of the real physical world with holographic objects provides numerous ways to influence how people perceive and interact with geographic space. Such holographic elements may for example improve orientation, navigation, and the mental representations of space generated through interaction with the environment. As AR hardware is still in an early development stage, scientific investigations of the effects of holographic elements on spatial knowledge and perception are fundamental for the development of user-oriented AR applications. However, accurate and replicable positioning of holograms in real world space, a highly relevant precondition for standardized scientific experiments on spatial cognition, is still an issue to be resolved. In this paper, we specify technical causes for this limitation. Subsequently, we describe the development of a Unity-based AR interface capable of adding, selecting, placing and removing holograms. The capability to quickly reposition holograms compensates for the lack of hologram stability and enables the implementation of AR-based geospatial experiments and applications. To facilitate the implementation of other task-oriented AR interfaces, code examples are provided and commented.

Framework for designing motivational augmented reality applications in vocational education and training

One of the greatest advantages of augmented reality (AR) in education is that AR increases student motivation. Nevertheless, there is a gap between the research on student motivation in AR and the definition of frameworks to inform and guide the design and development of AR applications that effectively support student motivation. In this paper, we attempt to bridge that gap as we introduce and evaluate a framework for designing motivational AR applications. Our framework has been built upon three theoretical foundations: motivational design, universal design for learning and co-creation. The evaluation study was conducted with 58 chemistry students enrolled in the vocational education and training (VET) program for Laboratory Operations, and we found that the framework not only effectively supports the four dimensions of Keller's (2010) ARCS (attention, relevance, confidence and satisfaction) model of motivation, but also demonstrates exceptional results in the Attention and Confidence dimensions of motivation.

Camera localization for augmented reality and indoor positioning: a vision-based 3D feature database approach

ABSTRACTThe recent fast development in computer vision and mobile sensor technology such as mobile LiDAR and RGB-D cameras is pushing the boundary of the technology to suit the need of real-life applications in the fields of Augmented Reality (AR), robotics, indoor GIS and self-driving. Camera localization is often a key and enabling technology among these applications. In this paper, we developed a novel camera localization workflow based on a highly accurate 3D prior map optimized by our RGB-D SLAM method in conjunction with a deep learning routine trained using consecutive video frames labeled with high precision camera pose. Furthermore, an AR registration method tightly coupled with a game engine is proposed, which incorporates the proposed localization algorithm and aligns the real Kinetic camera with a virtual camera of the game engine to facilitate AR application development in an integrated manner. The experimental results show that the localization accuracy can achieve an average error of 35 cm based on a fine-tuned prior 3D feature database at 3 cm accuracy compared against the ground-truth 3D LiDAR map. The influence of the localization accuracy on the visual effect of AR overlay is also demonstrated and the alignment of the real and virtual camera streamlines the implementation of AR fire emergency response demo in a Virtual Geographic Environment.

Development of Augmented Reality Application for Interactive Smart Materials

The paper presents research related to thermochromic inks printed on textile materials. These types of materials are smart materials, they act as packaging indicators, and we use them to develop a software application on mobile devices. That application identifies the most significant changes in parameters of the goods contained in the packaging, such as temperature changes during the storage and transport (goods packaged in packaging that is sensitive to heat), or such as pharmaceuticals and frozen food, etc. This paper aims to demonstrate the possibility of connecting thermochromic materials and Augmented Reality technology through the development of an application for identifying thermochromic materials changes. The tested samples were printed on the textile with a screen printing technique with conventional and thermochromic leuco inks on various textile materials. The Augmented Reality platform Vuforia was used for developing a software application for mobile devices. The application was developed for the iOS mobile platform. The result of the research is the functional application that actively monitors and displays changes in thermochromic materials due to temperature changes, which identifies the effect of heat on the goods in textile packaging.

AR in VR: assessing surgical augmented reality visualizations in a steerable virtual reality environment.

PURPOSE : Augmented reality (AR) has emerged as a promising approach to support surgeries; however, its application in real world scenarios is still very limited. Besides sophisticated registration tasks that need to be solved, surgical AR visualizations have not been studied in a standardized and comparative manner. To foster the development of future AR applications, a steerable framework is urgently needed to rapidly evaluate new visualization techniques, explore their individual parameter spaces and define relevant application scenarios. METHODS : Inspired by its beneficial usage in the automotive industry, the underlying concept of virtual reality (VR) is capable of transforming complex real environments into controllable virtual ones. We present an interactive VR framework, called Augmented Visualization Box (AVB), in which visualizations for AR can be systematically investigated without explicitly performing an error-prone registration. As use case, a virtual laparoscopic scenario with anatomical surface models was created in a computer game engine. In a study with eleven surgeons, we analyzed this VR setting under different environmental factors and its applicability for a quantitative assessment of different AR overlay concepts. RESULTS : According to the surgeons, the visual impression of the VR scene is mostly influenced by 2D surface details and lighting conditions. The AR evaluation shows that, depending on the visualization used and its capability to encode depth, 37% to 91% of the experts made wrong decisions, but were convinced of their correctness. These results show that surgeons have more confidence in their decisions, although they are wrong, when supported by AR visualizations. CONCLUSION : With AVB, intraoperative situations are realistically simulated to quantitatively benchmark current AR overlay methods. Successful surgical task execution in an AR system can only be facilitated if visualizations are customized toward the surgical task.

Continuous dynamic gesture spotting algorithm based on Dempster-Shafer Theory in the augmented reality human computer interaction.

Human-computer interaction (HCI) is an important feature of augmented reality (AR) technology. The naturalness is the inevitable trend of HCI. Gesture is the most natural and frequently used body auxiliary interaction mode in daily interactions except for language. However, there are often meaningless, subconscious gesture intervals between the two adjacent dynamic gestures. So, continuous dynamic gesture spotting is the premise and basis of dynamic gesture recognition, but there is no mature and unified algorithm to solve this problem. In order to realize the natural HCI based on gesture recognition entirely, a general AR application development platform is presented in this paper. According to the position and pose tracking data of the user's hand, the dynamic gesture spotting algorithm based on evidence theory is proposed. Firstly, Through analysis of the speed change of hand motion during the dynamic gestures, three knowledge rules are summed up. Then, accurate dynamic gesture spotting is realized with the application of evidence reasoning. Moreover, this algorithm first detects the starting point of gesture in the rising trend of hand motion speed, eliminates the delay between spotting and recognition, and thus ensures real-time performance. Finally, the algorithm is verified in several AR applications developed on the platform. There are two main experimental results. First, there are six users participating in the dynamic gesture spotting experiment, and the gesture spotting accuracy can meet the demand. Second, The accuracy of recognition after spotting is higher than that of the simultaneous recognition and spotting. So, It can be concluded that the proposed continuous dynamic gesture spotting algorithm based on Dempster-Shafer theory can extract almost all the effective dynamic gestures in the HCI of our AR platform, and on this basis, it can effectively improve the accuracy of the subsequent dynamic gesture recognition.

XD-AR

Augmented Reality (AR) developers face a proliferation of new platforms, devices, and frameworks. This often leads to applications being limited to a single platform and makes it hard to support collaborative AR scenarios involving multiple different devices. This paper presents XD-AR, a cross-device AR application development framework designed to unify input and output across hand-held, head-worn, and projective AR displays. XD-AR's design was informed by challenging scenarios for AR applications, a technical review of existing AR platforms, and a survey of 30 AR designers, developers, and users. Based on the results, we developed a taxonomy of AR system components and identified key challenges and opportunities in making them work together. We discuss how our taxonomy can guide the design of future AR platforms and applications and how cross-device interaction challenges could be addressed. We illustrate this when using XD-AR to implement two challenging AR applications from the literature in a device-agnostic way.

Machine tool setup instructions in the smart factory using augmented reality: a system construction perspective

Machine setup instructions are notable examples of such information. This paper advocates the use of augmented reality (AR) to present such information addressing in an intuitive manner the demonstration of setup tasks on the variety of machine tools that are available in a factory and for the multitude of parts that are produced. Turning and machining centres are used as typical machine tools, for which setup instruction applications were created on a widely used computer game development platform enhanced by standard AR functionality based on target markers present on the scene. This AR demonstrator has been primarily created as a proof of concept that highlights the feasibility of such low-cost, efficient and user friendly AR applications of industrial guidance and training. The emphasis of the work is on technical aspects of AR application development, which is lacking in literature. In particular, interfacing of distance sensors that impart intelligence, scenario structuring in terms of states and state threads, as well as techniques ensuring expansibility, flexibility and ease of authoring of such applications are demonstrated.

Augmented reality, the future of contextual mobile learning

Purpose This study aims to show the relevance of augmented reality (AR) in mobile learning for the 21st century. With AR, any real-world environment can be augmented by providing users with accurate digital overlays. AR is a promising technology that has the potential to encourage learners to explore learning materials from a totally new perspective. Besides, the advancements made in information technology further broaden the scope for educational AR applications. Furthermore, the proliferation of wireless mobile devices such as smartphones and tablets is also introducing AR into the mobile domain. Design/methodology/approach This discussion paper gives an insight of the different potential fields of application of AR and eventually proposes an AR application that will give a completely different learning experience for learners. This AR mobile application will not only provide learners with supplementary information but will also assist lecturers in their teaching process. There are certain concepts in computer science at the tertiary level that are at times difficult for learners to understand using the traditional classroom approach. Through this AR application developed, the learners are able to see what is happening and experience a different form of learning where the focus is more on “learning by doing” and on the ability of visualizing the complete set of steps involved for a particular operation. Finally what is proposed is a generic framework/process for the development of AR applications for learning purposes. Findings The AR application developed and tested has proved to be helpful in understanding complex concepts of computer science that average students have much difficulty in understanding. Through AR, learning has been brought to a new dimension where the students can easily visualize what is happening and easily understand complex concepts. This low-cost system that has been proposed can track and detect both markerless and marker-based images. A number of experiments have also been carried out to determine a set of best practices for the development and use of such AR applications. Originality/value Learners have been able to have a more interactive and enriching learning experience through two-dimensional and three-dimensional digital augmentations. The AR mobile application has been enhancing the cognitive skills of learners through enabling them to scan images from printed materials with their smartphones. Then, informative digital augmentation has been overlaid in real time on the mobile screen with the image preview still in the background.

An augmented reality tool to validate the assembly sequence of a discrete product

The need for more flexible tools and reduction of time and cost has led to the implementation of augmented reality (AR) and virtual reality (VR) techniques in the product design and development process. Those techniques have already been used in the conceptual, manufacturing and assembly stages of product design instead of or in extension of the physical prototypes. Such virtual applications have demonstrated superior performance in assembly process design and evaluation of activities that present information about different assembly states in real time, thanks to their flexibility in manipulating and creating new working scenarios. Here, the development of an AR application, called PoliART, aimed at the visual evaluation of assembly sequences at early stages of design is presented. At an industrial level this allows collaborative work between designers and manufacturing engineers from the very beginning in order to consider assembly devices, times and resources, with a short implementation time and reduced costs.
