Augmented Reality (AR) is a technology used for maintenance support of existing products. The service instructions are depicted directly into the operator’s vision and enhance his product view while maintaining the item. In order to provide high-quality maintenance support the manuals have to be created and tested at the development stage of the product. This paper describes a possible solution for testing AR instructions on virtual prototypes by combining AR and Virtual Reality (VR) technology. Technical aspects for combining VR and AR displays are outlined and a combined system is presented. Furthermore, the paper shows the development of a specific test scenario for evaluating the created system and contains design patterns for depicting AR instructions in Virtual Environments. Finally, the usability of the solution is tested by a user study.

The Right

A lack of required data resources is one of the challenges of accepting the Augmented Reality (AR) to provide the right services to the users, whereas the amount of spatial information produced by people is increasing daily. This research aims to design a personalized AR that is based on a tourist system that retrieves the big data according to the users’ demographic contexts in order to enrich the AR data source in tourism. This research is conducted in two main steps. First, the type of the tourist attraction where the users interest is predicted according to the user demographic contexts, which include age, gender, and education level, by using a machine learning method. Second, the correct data for the user are extracted from the big data by considering time, distance, popularity, and the neighborhood of the tourist places, by using the VIKOR and SWAR decision making methods. By about 6%, the results show better performance of the decision tree by predicting the type of tourist attraction, when compared to the SVM method. In addition, the results of the user study of the system show the overall satisfaction of the participants in terms of the ease-of-use, which is about 55%, and in terms of the systems usefulness, about 56%.

The Impact

In the context of industrial production, a worker that wants to program a robot using the hand-guidance technique needs that the robot is available to be programmed and not in operation. This means that production with that robot is stopped during that time. A way around this constraint is to perform the same manual guidance steps on a holographic representation of the digital twin of the robot, using augmented reality technologies. However, this presents the limitation of a lack of tangibility of the visual holograms that the user tries to grab. We present an interface in which some of the tangibility is provided through ultrasound-based mid-air haptics actuation. We report a user study that evaluates the impact that the presence of such haptic feedback may have on a pick-and-place task of the wrist of a holographic robot arm which we found to be beneficial.

3D maps such as Google Earth and Apple Maps (3D mode), in which users can see and navigate in 3D models of real worlds, are widely available in current mobile and desktop environments. Users usually use a monitor for display and a keyboard/mouse for interaction. Head-mounted displays (HMDs) are currently attracting great attention from industry and consumers because they can provide an immersive virtual reality (VR) experience at an affordable cost. However, conventional keyboard and mouse interfaces decrease the level of immersion because the manipulation method does not resemble actual actions in reality, which often makes the traditional interface method inappropriate for the navigation of 3D maps in virtual environments. From this motivation, we design immersive gesture interfaces for the navigation of 3D maps which are suitable for HMD-based virtual environments. We also describe a simple algorithm to capture and recognize the gestures in real-time using a Kinect depth camera. We evaluated the usability of the proposed gesture interfaces and compared them with conventional keyboard and mouse-based interfaces. Results of the user study indicate that our gesture interfaces are preferable for obtaining a high level of immersion and fun in HMD-based virtual environments.

<p class="Abstract"><span lang="EN-US">In light of the increasing technological developments, working life and education is changing and becoming more complex, interconnected and digital. These changed circumstances require new and modified competences of future employees. Education has to respond to the changing requirements in working life. To prepare for this, a technological-oriented teaching and learning process as well as gaining practical experience is crucial for students. In this context, Virtual Reality (VR) technologies provide new opportunities for practical experience in higher education, where they can further intensify the students learning experiences to a more immersive and engaging involvement in the learning process. To evaluate the potential of immersive virtual learning environments (VLE) for higher education and to understand more deeply which kind of experiences students gain while learning in immersive virtual environments (VE) an experimental research study is carried out. The paper describes education in light of industry 4.0 first and gives an overall view of immersive learning and the role of VR Technologies. Then the user study to measure user experience (UX) in immersive VLE is presented. Preliminary results are outlined and discussed with a view of further research.</span></p>

Design Aspect

A traditional house is a house that has a unique building characteristic in an area that describes the culture of the area itself. Traditional houses are also unique in terms of form, function and meaning of the building. As Indonesians, we must introduce one of the existing cultures so that it is not forgotten by the community, especially school children. Judging from the development of technology, we must make new things in introducing traditional houses. From the results of research conducted at SD IT BINA INSANI, the teachers there still use conventional media in the form of textbooks and thematic books for the learning process. Therefore, the authors created an application to introduce western Indonesian traditional houses using Augmented Reality called RA-IBB as an introduction medium. This application is based on Android so that teachers can easily explain material about traditional houses and can show traditional houses in 3D without having to come directly to the province. And for students to be able to study traditional houses wherever and whenever. The making of this application uses the waterfall method for the development stage. The RA-IBB application contains materials about western Indonesian traditional houses and their 3d objects and quiz questions that use random shuffle algorithm questions. The random shuffle algorithm is a randomized question from an array or record. Based on the User Acceptance Test (UAT) for teachers, the results obtained from several aspects, namely the design aspect yields a percentage of 91%, the application information aspect produces a percentage of 91.

Interface Metaphor

Nowadays, Augmented-Reality (AR) head-mounted displays (HMD) deliver a more immersive visualization of virtual contents, but the available means of interaction, mainly based on gesture and/or voice, are yet limited and obviously lack realism and expressivity when compared to traditional physical means. In this sense, the integration of haptics within AR may help to deliver an enriched experience, while facilitating the performance of specific actions, such as repositioning or resizing tasks, that are still dependent on the user’s skills. In this direction, this paper gathers the description of a flexible architecture designed to deploy haptically enabled AR applications both for mobile and wearable visualization devices. The haptic feedback may be generated through a variety of devices (e.g., wearable, graspable, or mid-air ones), and the architecture facilitates handling the specificity of each. For this reason, within the paper, it is discussed how to generate a haptic representation of a 3D digital object depending on the application and the target device. Additionally, the paper includes an analysis of practical, relevant issues that arise when setting up a system to work with specific devices like HMD (e.g., HoloLens) and mid-air haptic devices (e.g., Ultrahaptics), such as the alignment between the real world and the virtual one. The architecture applicability is demonstrated through the implementation of two applications: (a) Form Inspector and (b) Simon Game, built for HoloLens and iOS mobile phones for visualization and for UHK for mid-air haptics delivery. These applications have been used to explore with nine users the efficiency, meaningfulness, and usefulness of mid-air haptics for form perception, object resizing, and push interaction tasks. Results show that, although mobile interaction is preferred when this option is available, haptics turn out to be more meaningful in identifying shapes when compared to what users initially expect and in contributing to the execution of resizing tasks. Moreover, this preliminary user study reveals some design issues when working with haptic AR. For example, users may be expecting a tailored interface metaphor, not necessarily inspired in natural interaction. This has been the case of our proposal of virtual pressable buttons, built mimicking real buttons by using haptics, but differently interpreted by the study participants.

Technological advancements have provided heritage with new learning environments via the use of virtual and augmented reality, which can foster the accessibility and understanding of culture and propose new ways of interacting with heritage. Therefore, in this study, a systematic evaluation is carried out of n=197 heritage education programs listed in the database of the Observatorio de Educación patrimonial en España (OEPE) (the Spanish Heritage Education Observatory–SHEO) which, in their descriptions, integrate the use of virtual environments and/or augmented reality to promote learning on the part of the user. The objectives of this study are: (1) to analyse the state of the art, (2) to evaluate the quality of their educational designs via the “analysis and assessment sequential method for heritage education programs” (SAEPEP-OEPE) and (3) to identify variables which can be improved or which have a significant influence on the quality of the programs. Highlights of the results include: (a) the increasing implementation of these technologies in heritage education programs, with the greater presence of virtual resources than of learning environments, (b) the low level of the scope of educational quality in their designs, particularly their assessment, and (c) the inclusion of advanced technologies slightly decreases the specificity of the educational design.
