Yet the conditions under which such augmentations yield positive experience remain unclear. In this study, we tested whether the experience of being augmented depends on compatibility with the given task. In a between-subject experimental vignette study (N=120 experienced VR users), participants watched first-person videos in one of three conditions: (1) reality-oriented object manipulation (control), (2) task-compatible augmentation (growing/shrinking), or (3) non-task-compatible augmentation (distant grasping). As expected, the augmentation-oriented design only led to a greater sense of augmentation when it was compatible with the task. In turn, the experience of augmentation was positively related to positive affect, need fulfillment, and hedonic quality. These findings suggest that unreal augmentations are beneficial, but only when the new abilities match the task.

However, the development of these technologies often overlooks the perspectives of patients and their families and socio-cultural surroundings, posing significant social, technological, and ethical challenges related to data bias, empowerment or surveillance, respectively. Bringing together interdisciplinary, interprofessional, and intersectoral collaboration in a systematic way seems to be a crucial element for adressing these issues and ensuring the meaningful integration of sensitive data and AI technologies into patient-centred healthcare arrangements. In this workshop, researchers and practitioners from diverse related disciplines, including HCI, AI, social and cultural sciences, healthcare, gerontology, etc., are invited to share their case studies on innovative health technologies and medical AI. Drawing from contextual best practices, as well as challenges and failures, the workshop organizers aim to collectively devise a systematic approach for co-designing and implementing telemedical innovations in real-world healthcare settings.

Workshop der GI-Fachgruppe VR/AR N2 - In this paper we propose an integrated immersive augmented reality solution for a software tool supporting spacecraft design and verification. The spacecraft design process relies on expertise in many domains, such as thermal and structural engineering. The various subsystems of a spacecraft are highly interdependent and have differing requirements and constraints. In this context, interactive visualizations play an important role in making expert knowledge accessible. Recent immersive display technologies offer new ways of presenting and interacting with computer-generated content. Possibilities and challenges for spacecraft configuration employing these technologies are explored and discussed. A user interface design for an application using the Microsoft HoloLens is proposed. To this end, techniques for selecting a spacecraft component and manipulating its position and orientation in 3D space are developed and evaluated. Thus, advantages and limitations of this approach to spacecraft configuration are revealed and discussed.

As a first step, a simple, understandable formula was developed how to advance from the problem to the program in 5 operative steps: read it → get it → think it → note it → code it. In order to reduce the cognitive load of the learners effectively, 5Code was designed such that all 5 steps are permanently presented, accessible and executable. Thus, learners are provided with the entire programming context from presentation of the task via own notes and annotations to the code area. Learners can mark and annotate any part of the given task’s text; these annotations can be edited as notes with own comments. Furthermore, the notes can be dragged into the code area, where they are shown as comments in the coding language. Any modifications in the comments are synchronized between notes and code. 5Code is implemented as a web-application. It is used in university introductory courses on object oriented programming.

T1 - A collaborative numerical and experimental investigation of flapping-wing propulsion T2 - 40th AIAA Aerospace Sciences Meeting & Exhibit N2 - An international, collaborative investigation is undertaken to evaluate the relative merits and limitations of various numerical methods and experimental measurement techniques, specifically for the analysis of flapping-wing propulsion. A finite aspect-ratio configuration is extensively investigated, both quantitatively and qualitatively, in a low-speed wind tunnel. Direct force measurements are made, as well as time-accurate and time-averaged laser Doppler velocimetry and unsteady flow visualization. The reduced frequency, mean angle of attack, aspect ratio and Reynolds number are varied in the experiments. The experiment is numerically simulated using flatplate theory, two and three-dimensional panel codes, and two and three-dimensional Euler and Navier- Stokes solvers. The ability of each of the methods to capture important aspects of the flow physics are evaluated through comparisons with each other and the experimental data. Additionally, the comparisons indicate areas where further research is needed. The collaborative effort provides a survey of available capabilities and provides a fixed set of flappingwing data for others to compare against.

This interdisciplinary community is fairly new, it is still not well integrated and is therefore confronted with differing perspectives, processes, methods, tools, vocabularies, and standards. We present a Common Body of Knowledge (CBK) to overcome the aforementioned problems. We capture use cases from research and practice to derive requirements for the CBK. Our CBK collects, integrates, and structures knowledge from the different disciplines based on an ontology that allows one to semantically enrich content to be able to query the CBK. The CBK heavily relies on user participation, making use of the Semantic MediaWiki as a platform to support collaborative writing. The ontology is complemented by a conceptual framework, consisting of concepts to structure the knowledge and to provide access to it, and a means to build a common terminology. We also present organizational factors covering dissemination and quality assurance.

The values were compared to the data from a freshly calibrated SMPS (Grimm SMPS+C) as a reference system. The SMPS measured the particle number concentration as well as the particle number size distribution in a range from 5 nm to 350 nm. This was done as a quality assurance for the use of these portable devices for other measurement campaigns for detecting the particle number concentration in mobile applications by e.g. unmanned aerial systems, bicycles, or small aircraft. The results show a good correlation between all the systems. The agreement between the reference system and the NanoCheck was really good, but lower between the DiSCMini and the reference system. Due to the good correlation the data could be post processed with a correction function to reduce the deviation. Finally, it can be stated, that both systems work well under environmental conditions and are well suited for the mobile use for the investigation of ultrafine particle concentration.

Due to this confounding of data and methods, it is difficult to assess the suitability of statistical modelling techniques used in the literature. Therefore, five different methods and two performance metrics were applied to three existing soundscape datasets to model soundscape Pleasantness and Eventfulness based on seven acoustic and three sociodemographic predictors. Datasets differed in soundscape type (urban outdoor vs indoor), experimental setting (field- vs lab-based), size, and study design (site- vs person-centered). The fixed-effects and mixed-effects methods ranged from linear to nonlinear regression based on advanced machine learning approaches. Results showed that models performed better for Eventfulness than for Pleasantness in most cases, while performance as measured by the out-of-sample R2 was dependent on the total variance of the target, especially in both field studies with imbalanced targets and groups. Nonlinear methods consistently outperformed linear regression, with random forest and extreme gradient boosting performing particularly well, while the performance levels of all nonlinear methods remained comparable. Mixed-effects models provided a more generalized, albeit slightly smaller prediction performance when tested on unknown groups. Finally, this study motivates the use of cross-validation with special splitting for analyzing small imbalanced datasets.
