In recent years, the use of technology in the museum context has changed radically. It has switched from the display of information to offering emotive, immersive, and rich experiences with heritage. Virtual interactive media have the potential to put museums back into a relevant place in our increasingly digital society. The emergence of augmented-reality glasses offers the possibility to test and implement new methodologies compatible with this aim. However, most of the first examples developed in recent years did not take advantage of the possibilities of this new medium. This paper presents a novel methodology for producing mixed-reality applications for museums and heritage sites, with an intuitive, immersive, and natural way of operating. An experimental prototype designed for the archaeological museum of the Almoina is shown in the paper to demonstrate the benefits of the proposed system and methodology of production. In addition, the paper shows the results of several tests.

Cultural heritage is the asset of tourism industry to attract tourist for visiting a country. Cultural heritage needs to be conserved in order to prolong the life from being deterioration. However, conservation needs huge financial cost and this reason becomes the major obstacles for cultural heritage to be maintained its existence in a country. Nowadays, digital cultural heritage conservation is alternatively utilized as it reduces the cost of conservation in the form of digital interpretive media such as video, animation, 3D simulation, virtual reality, and augmented reality. Therefore, this study attempted to seek about the availability of digital interpretive media at cultural heritage sites through a survey. This paper presents the findings of availability level of digital media in the heritage sites in Yogyakarta, Indonesia. The findings show that the availability of digital media in Yogyakarta cultural heritage sites are mostly in traditional media types such as signs, brochures, maps, leaflets, and books. In attracting tourist, it is suggested that the cultural heritage sites should be provided with more advance interpretive media, namely computer simulations; personal stereo guided tours, virtual reality, and recently augmented reality as a way to conserve cultural heritage information and values.

The Difference

The purpose of the article is to explore the transformation of artistic practices under the influence of virtual and augmented reality. The methodology is based on the application of the dialectical method, which allows to reveal the specifics of virtual / augmented / mixed realities through the prism of the dialectic of interaction between technology and man. The scientific novelty of the results is the analysis of the essence of the transformation of artistic practices under the influence of virtual and augmented reality, in particular, introduced into scientific circulation data on art projects using innovative technologies of augmented and mixed reality as a clear example of integration of the latter into art. Transboundary is considered from two points of view - the convergence of art and its reconstruction. It is stated that the implementation of projects using AR and VR technology is currently impossible without the appropriate logistics and computer technology skills. The indirectness of translation and perception of cultural experience by digital devices that determine a new technological format of personality inculturation is considered. Conclusions. These changes affect all spheres of society, erasing the spatio-temporal boundaries and involving people in an interactive creative process. Art responds most dynamically and reflects all changes in society, and modern cultural institutions are forced to take into account these trends and on this basis to form strategies for development and interaction with various stakeholders based on the use of virtual (VR), augmented (AR) reality. The difference between virtual art and other forms of art using computer technology is that its basis is not representation, but communication. Thus, numerous creative projects, implemented with the help of augmented and mixed reality, demonstrate the active use of technology in art, in the process of creating a movie, virtual exhibitions, etc.

Color appearance models have been extensively studied for characterizing and predicting the perceived color appearance of physical color stimuli under different viewing conditions. These stimuli are either surface colors reflecting illumination or self-luminous emitting radiations. With the rapid development of augmented reality (AR) and mixed reality (MR), it is critically important to understand how the color appearance of the objects that are produced by AR and MR are perceived, especially when these objects are overlaid on the real world. In this study, nine lighting conditions, with different correlated color temperature (CCT) levels and light levels, were created in a real-world environment. Under each lighting condition, human observers adjusted the color appearance of a virtual stimulus, which was overlaid on a real-world luminous environment, until it appeared the whitest. It was found that the CCT and light level of the real-world environment significantly affected the color appearance of the white stimulus, especially when the light level was high. Moreover, a lower degree of chromatic adaptation was found for viewing the virtual stimulus that was overlaid on the real world.

Simulation-based medical training is considered an effective tool to acquire/refine technical skills, mitigating the ethical issues of Halsted’s model. This review aims at evaluating the literature on medical simulation techniques based on augmented reality (AR), mixed reality (MR), and hybrid approaches. The research identified 23 articles that meet the inclusion criteria: 43% combine two approaches (MR and hybrid), 22% combine all three, 26% employ only the hybrid approach, and 9% apply only the MR approach. Among the studies reviewed, 22% use commercial simulators, whereas 78% describe custom-made simulators. Each simulator is classified according to its target clinical application: training of surgical tasks (e.g., specific tasks for training in neurosurgery, abdominal surgery, orthopedic surgery, dental surgery, otorhinolaryngological surgery, or also generic tasks such as palpation) and education in medicine (e.g., anatomy learning). Additionally, the review assesses the complexity, reusability, and realism of the physical replicas, as well as the portability of the simulators. Finally, we describe whether and how the simulators have been validated. The review highlights that most of the studies do not have a significant sample size and that they include only a feasibility assessment and preliminary validation; thus, further research is needed to validate existing simulators and to verify whether improvements in performance on a simulated scenario translate into improved performance on real patients.

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.

Virtual And Augmented Reality

Virtual and augmented reality, and other forms of mixed reality (MR), have become a focus of attention for companies and researchers. Before they can become successful in the market and in society, those MR systems must be able to deliver a convincing, novel experience for the users. By definition, the experience of mixed reality relies on the perceptually successful blending of reality and virtuality. Any MR system has to provide a sensory, in particular visually coherent, set of stimuli. Therefore, issues with visual coherence, that is, a discontinued experience of a MR environment, must be avoided. While it is very easy for a user to detect issues with visual coherence, it is very difficult to design and implement a system for coherence. This article presents a framework and exemplary implementation of a systematic enquiry into issues with visual coherence and possible solutions to address those issues. The focus is set on head-mounted display-based systems, notwithstanding its applicability to other types of MR systems. Our framework, together with a systematic discussion of tangible issues and solutions for visual coherence, aims at guiding developers of mixed reality systems for better and more effective user experiences.
