Objective The possibility of combining real and virtual environments is driving the increased use of augmented reality (AR) in education, including medical training. The aim of this multicentre study was to evaluate the students' perspective on the AR-based Rheumality GO!® app as a new teaching concept, presenting six real anonymized patient cases with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA). Methods The study encompassed 347 undergraduate medical students (232 women and 115 men) from four medical universities in Germany (Jena, Bad Nauheim/Gießen, Nuremberg, Erlangen). The course was divided into a theoretical refresher lecture followed by six AR-based cases in each of the three indications presented in the Rheumality GO! app. All participants evaluated the course after completion, assessing the benefit of the app from a student's perspective using a questionnaire with 16 questions covering six subject areas. Results The use of the AR-based app Rheumality GO! improved the understanding of pathologies in RA, PsA and axSpA for 99% of the participants. For 98% of respondents, the concept of AR with real patient data has made a positive impact on the teaching environment. On the other hand, 82% were in favour of the use of virtual tools (e.g. AR) in addition to this conventional approach. Conclusion The results of our survey showed that from the medical students' perspective, an AR-based concept like the Rheumality GO! app can complement rheumatology teaching in medical school as an effective and attractive tool though not replace bedside teaching.

Leading a socially engaged life is beneficial for the well-being of older adults. Immersive technologies, such as augmented reality (AR), have the potential to provide more engaging and vivid communication experiences compared to conventional digital tools. This qualitative study adopts a human-centered approach to discern the general attitudes and specific requirements of older adults regarding interpersonal communication facilitated by AR. We conducted semi-structured individual interviews with a sample of N = 30 older adults from Germany. During the interviews, participants evaluated storyboard illustrations depicting a fictional AR-enabled communication scenario centered around a grandparent and their adult grandchildren, which were represented as avatars within the AR environment. The study identified technological, emotional, social, and administrative requirements of older adults regarding the AR communication system. Based on these findings, we provide practical recommendations aimed at more inclusive technology design, emphasizing the significance of addressing the emotional needs of older adults, especially the perceived intimacy of AR-based interpersonal communication. Acknowledging and catering to these emotional needs is crucial, as it impacts the adoption of immersive technologies and the realization of their social benefits. This study contributes to the development of user-friendly AR systems that effectively promote and foster social engagement among older adults. [ABSTRACT FROM AUTHOR]

The digitalization of everyday school life has gained increasing importance for teachers in recent years. In Germany, this is especially true since the publication of the strategy on "Education in the Digital World" by the Standing Conference of the Ministers of Education and Cultural Affairs of the Länder in 2016, which calls for the acquisition of digital competencies by students. In this regard, it is of great importance that future teachers acquire important skills in the field of digitalization during their teacher training in order to effectively and pedagogically use digital media in instruction. In this paper, we present the concept of an intervention on the topic of "Simulation and Modeling" from the competency framework DiKoLAN, which provides possible guidance in relation to the question "which competencies in the field of digitalization should be taught during teacher training?" One focus of the presented concept is the technology of "Augmented Reality," which has already been described as an effective teaching and learning tool. Furthermore, evaluation results of the seminar are presented, which examine both the effectiveness in terms of conveying the desired competencies through the measurement of self-efficacy expectations, and the attitudes of the pre-service teachers towards the use of AR in science education. The evaluation of the intervention measure shows a significant increase in pre-service teachers' self-efficacy expectations across all areas of competencies to be taught, as well as a significantly more positive attitude towards the use of AR in science teaching.

During crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefulness of Twitter data for achieving situation awareness and conducted interviews with emergency operators to derive filter strategies for social media data. We synthesized the results by discussing how the unique interface of augmented reality can be used to integrate social media data into emergency control rooms for situation awareness support.

Augmented Reality (AR) is a technology that has benefited from the massification of computational devices, putting it in the focus of researchers as a novel teaching aid in engineering. For this very reason, a great amount of information about AR in engineering education is emerging constantly. To synthesize the information, a Systematic Literature Review (SLR) was carried out and 4 research questions were raised. It was found out the researcher´s trend for the development and testing of software that takes advantage of AR for engineering students. It was also found that Germany and India are the leading nations on investigations about the investigated topic. On the software side, Unity is the most used tool for creating applications and that the target hardware is smartphone. Finally, the high interest of researchers to increase motivation in students is evidenced in this SLR and recommendations were made based on the researcher’s findings. [ABSTRACT FROM AUTHOR]

Media companies often fail to successfully adopt emergent technology-driven media innovations. In order to analyse the pitfalls of implementation and to identify media-organisation-specific weaknesses, eleven cases from the media and manufacturing industries in Germany that adopted XR (which encompasses virtual, mixed and augmented reality technology) were compared. Several organisational drivers were especially important for successful adoption such as top management support, existence of an innovation champion, fit with the company/innovation strategy, cooperation with internal IT and long-term planning for the build-up of sustainable expertise within the companies. Whereas the media firms profited in some regards from their editorial background (i.e., high motivation of the projects' innovation champions), the lack of strategic planning and limited internal IT resources were found to hamper a successful adoption.

Purpose: Augmented reality improves planning and execution of surgical procedures. The aim of this study was to evaluate the feasibility of a 3D augmented reality hologram in live parotic surgery. Another goal was to develop an accuracy measuring instrument and to determine the accuracy of the system. Methods: We created a software to build and manually align 2D and 3D augmented reality models generated from MRI data onto the patient during surgery using the HoloLens® 1 (Microsoft Corporation, Redmond, USA). To assess the accuracy of the system, we developed a specific measuring tool applying a standard electromagnetic navigation device (Fiagon GmbH, Hennigsdorf, Germany). Results: The accuracy of our system was measured during real surgical procedures. Training of the experimenters and the use of fiducial markers significantly reduced the accuracy of holographic system (p = 0.0166 and p = 0.0132). Precision of the developed measuring system was very high with a mean error of the basic system of 1.3 mm. Feedback evaluation demonstrated 86% of participants agreed or strongly agreed that the HoloLens will play a role in surgical education. Furthermore, 80% of participants agreed or strongly agreed that the HoloLens is feasible to be introduced in clinical routine and will play a role within surgery in the future. Conclusion: The use of fiducial markers and repeated training reduces the positional error between the hologram and the real structures. The developed measuring device under the use of the Fiagon navigation system is suitable to measure accuracies of holographic augmented reality images of the HoloLens. [ABSTRACT FROM AUTHOR]

The augmented reality smartphone game Pokémon Go is one of the biggest commercial successes in the last years, posing the question concerning the factors contributing to the game's success. An apparent distinction to other games is the strong brand Pokémon. We derive a research model based on the established theory of technology acceptance, which includes an established construct for nostalgic feelings – childhood brand nostalgia – and theorise on how it is related to beliefs about technology characteristics and the intention to play the game. For this purpose, we adapt one of the most prominent technology acceptance models for the consumer context and for hedonic information systems, the UTAUT2 model. Based on our model, we conduct a study with 418 active German players aged between 18 and 35. Our results indicate that the effect of childhood brand nostalgia on behavioural intention is fully mediated by the belief constructs. Thus, nostalgic feelings about Pokémon influence the intention of users through altering beliefs concerning Pokémon. We include nostalgic feelings in a technology acceptance model for the first time, therefore contributing to the theoretical advance in the IS domain. The results can be used to enhance the technology acceptance of newly designed products. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the delivery, acceptance and experiences regarding a traditional and teletreatment approach to mirror therapy as delivered in a randomized controlled trial. Design: Mixed methods, prospective study. Setting: Rehabilitation centres, hospital and private practices. Subjects: Adult patients with phantom pain following lower limb amputation and their treating physical and occupational therapists. Interventions: All patients received 4 weeks of traditional mirror therapy (n = 51), followed by 6 weeks of teletreatment (n = 26) or 6 weeks of self-delivered mirror therapy (n = 25). Main measures: Patient files, therapist logs, log files teletreatment, acceptance questionnaire and interviews with patients and their therapists. Results: In all, 51 patients and 10 therapists participated in the process evaluation. Only 16 patients (31%) received traditional mirror therapy according to the clinical framework during the first 4 weeks. Between weeks 5 and 10, the teletreatment was used by 14 patients (56%) with sufficient dose. Teletreatment usage decreased from a median number of 31 (weeks 5–10) to 19 sessions (weeks 11–24). Satisfactory teletreatment user acceptance rates were found with patients demonstrating higher scores (e.g. regarding the usefulness to control pain) than therapists. Potential barriers for implementation of the teletreatment perceived by patients and therapists were related to insufficient training and support as well as the frequency of technical problems. Conclusion: Traditional mirror therapy and the teletreatment were not delivered as intended in the majority of patients. Implementation of the teletreatment in daily routines was challenging, and more research is needed to evaluate user characteristics that influence adherence and how technology features can be optimized to develop tailored implementation strategies.

Purpose:New rehabilitation strategies for post-stroke upper limb rehabilitation employing visual stimulation show promising results, however, cost-efficient and clinically feasible ways to provide these interventions are still lacking. An integral step is to translate recent technological advances, such as in virtual and augmented reality, into therapeutic practice to improve outcomes for patients. This requires research on the adaptation of the technology for clinical use as well as on the appropriate guidelines and protocols for sustainable integration into therapeutic routines. Here, we present and evaluate a novel and affordable augmented reality system (Augmented Reflection Technology, ART) in combination with a validated mirror therapy protocol for upper limb rehabilitation after stroke. Method:We evaluated components of the therapeutic intervention, from the patients’ and the therapists’ points of view in a clinical feasibility study at a rehabilitation centre. We also assessed the integration of ART as an adjunct therapy for the clinical rehabilitation of subacute patients at two different hospitals. Results:The results showed that the combination and application of theBerlin Protocol for Mirror Therapytogether with ART was feasible for clinical use. This combination was integrated into the therapeutic plan of subacute stroke patients at the two clinical locations where the second part of this research was conducted. Conclusions:Our findings pave the way for using technology to provide mirror therapy in clinical settings and show potential for the more effective use of inpatient time and enhanced recoveries for patients. Implications for RehabilitationComputerised Mirror Therapy is feasible for clinical useAugmented Reflection Technology can be integrated as an adjunctive therapeutic intervention for subacute stroke patients in an inpatient settingVirtual Rehabilitation devices such as Augmented Reflection Technology have considerable potential to enhance stroke rehabilitation [ABSTRACT FROM PUBLISHER]

Participants: A. Baumeister (GERMANY), J. Bleja (Germany), B. Klein (Germany), A. Kucharski (GERMANY) S. MERKEL (GERMANY), M. Ringwald (GERMANY), B. KLEIN (discussant) ISSUE: The session circles around new technologies that have gained increasing relevance for the field of gerontechnology. It follows the idea that these new technologies ask for new theories and methods not only to understand their technical functionality but also social aspects and consequences. Applying theories and methods of social sciences, sciences, and technology studies (STS) and media studies, the session follows an interdisciplinary approach. CONTENT: The symposium brings together research and evidence of the German speaking chapters of the ISG (Austria, Germany, and Switzerland) and covers a broad spectrum of recent developments. STRUCTURE: Alexander Kucharski shares insights from an exploratory study on the domestication of smart speakers by older persons in Germany. Drawing on seven case studies he explores perspectives of older smart speaker users on their real-world domestication processes of smart speakers to understand how older users negotiate(d) the appropriation, meaning and (non)-use of smart speakers and its contents/applications within their individual socio-technical contexts, i.e. life-worlds. Sebastian Merkel also deals with the topic of smart speakers by focusing on applications or so-called skills and images of ageing. He concludes that most skills addressed at older persons rather emphasize deficit-oriented/medicalized images of aging and hence user representations. J. Bleja reports on the development of a chatbot operated via smart speakers for care consultation. As a first task expert interviews have been carried out. The results indicate potential use cases, support of the anamnesis procedure being one of them. In the next two contributions, the focus is on assistive robotics. Annalies Baumeister presents a project to improve the use of a robotic arm for people with little or no arm function by an adaptive AI-based control system. In Workshops and interviews with the user groups everyday scenarios were identified which can improve significantly by this new way of user-robot-interaction. Key factor for acceptance is the embodiment of robots. Marina Ringwald presents the interdisciplinary development of an embodiment utilizing participatory design with older people as potential user group. Design options are realized in 3D models in augmented reality and evaluated in an iterative approach before a physical prototype is produced. Finally, Barbara Klein addresses the need to train professionals in the health and social care sector in these assistive digital technologies by presenting a certification course developed by a consortium of twelve partner in a European project. The materials will help professionals learn about and further communicate new solutions to support the independence and self-determination of their clients and beneficiaries. CONCLUSION: Consequently, it is argued that gerontechnology benefits from a closer cooperation and knowledge exchange of interdisciplinary research teams including professionals and user groups. Participatory design and involving older users and other stakeholders are key elements, but still more research is needed, especially when utilizing new methods such as augmented reality in the design and development processes.

In this paper, the authors reviewed the empirical augmented reality (AR) and online education studies, and those focused on designing or development of AR to help students learn, published in SSCI, SCI-EXPANDED, and A&HCI journals from 2003 to 2012. The authors in this study found that the number of AR and online education studies has significantly increased since 2009. Based on this review, it is found that contributors from Spain, Romania, Taiwan, and Germany had the most publications on AR and online education during 2003 to 2012. Moreover, the analysis of these selected papers reveals that most empirical AR and online education studies were conducted at universities, as well as in computer science courses. Furthermore, the quantitative research method was used more in the reviewed papers. The findings and analysis from this review may provide potential directions and insights for future AR and online education research. [ABSTRACT FROM AUTHOR]

At present, more than half of all building activity in the German building sector is undertaken within existing built contexts. The development of a conceptual and technological basis for the digital support of design directly on site, within an existing building context is the focus of the research project "Spatial Augmented Reality for Architecture" (SAR).This paper describes the goals achieved in one aspect of the project: the sampling of colors and materials at a scale of 1:1 using Augmented Realit (AR) technologies. We present initial results from the project; the development of an ad-hoc visualization of interactive data on arbitrary surfaces in real-world indoor environments using a mobile hardware setup. With this, it was possible to project the color and material qualities of a design directly onto almost all surfaces within a geometrically corrected, existing building. Initially, a software prototype "Spatial Augmented Reality for Architecture-Colored Architecture" (SAR-CA) was developed and then assessed based on evaluation results from a user study.

Digitalization of production environment, also called Industry 4.0 (the term invented by Wahlster Wolfgang in Germany) is now one of the hottest topics in the computer science departments at universities and companies. One of the most significant topics in this area is augmented reality (AR). The interest in AR has grown especially after the introduction of the Microsoft HoloLens in 2016, which made this technology available for researchers and developers all around the world. It is divided into numerous subtopics and technologies. These wireless, see-through glasses give a very natural human-machine interface, with the possibility to present certain necessary information right in front of the user's eyes as 3D virtual objects, in parallel with the observation of the real world, and the possibility to communicate with the system by simple gestures and speech. Scientists noted that in-depth studies connected to the effects of AR applications are presently sparse. In the first part of this paper, the authors recall the research from 2019 about the new method of manual wiring support with the AR glasses. In the second part, the study (tests) for this method carried out by the research team is described. The method was applied in the actual production environment with consideration of the actual production process, which is manual wiring of the industrial enclosures (control cabinets). Finally, authors deliberate on conclusions, technology's imperfections, limitations, and future possible development of the presented solution. [ABSTRACT FROM AUTHOR]
