In the current ARD report 'Mein Körper. Mein (Mehr-) Gewicht' on the topic of body positivity and health risks of obesity, the HCI Chair was able to present the ViTras project, in which the psychological effect of VR/AR is used to increase the effectiveness of obesity therapy and to reduce the relape rate.

We were proud to present our work at the CHI conference 2023 right here in Germany.

On June 16th at 1pm the XR Hub Würzburg hosts the event 'Dive into XR' for the Digitaltag 2023. Among other things, visitors will have the opportunity to experience different tracking solutions in the newly established motion capture lab.

As part of a guest lecture by Nikolaus Böll, we are pleased to offer an introduction to the topic of adaptive audio using FMOD.

Lena Fischer from Games/Bavaria will hold a guest lecture about the opportunities for game developers after graduation and useful tips on job hunting while entering the industry.

Abstract:
Medical graduates lack procedural skills experience required to manage emergencies. Recent advances in virtual reality (VR)technology enable the creation of highly immersive learning environments representing easy-to-use and affordable solutionsfor training with simulation. However, the feasibility in compulsory teaching, possible side effects of immersion, perceivedstress, and didactic benefits have to be investigated systematically. VR-based training sessions using head-mounted displaysalongside a real-time dynamic physiology system were held by student assistants for small groups followed by debriefing witha tutor. In the pilot study, 36 students rated simulation sickness. In the main study, 97 students completed a virtual scenarioas active participants (AP) and 130 students as observers (OBS) from the first-person perspective on a monitor. Participantscompleted questionnaires for evaluation purposes and exploratory factor analysis was performed on the items. The extent ofsimulation sickness remained low to acceptable among participants of the pilot study. In the main study, students valued therealistic environment and guided practical exercise. AP perceived the degree of immersion as well as the estimated learn-ing success to be greater than OBS and proved to be more motivated post training. With respect to AP, the factor “sense ofcontrol” revealed a typical inverse U-shaped relationship to the scales “didactic value” and “individual learning benefit”.Summing up, curricular implementation of highly immersive VR-based training of emergencies proved feasible and founda high degree of acceptance among medical students. This study also provides insights into how different conceptions of perceived stress distinctively moderate subjective learning success.

Abstract:
History education often struggles with a lack of interest from students. Serious games can help make learning about history more engaging. Students can directly experience situations of the past as well as interact and communicate with agents representing people of the respective era. This allows for situated learning. Besides using computer screens, the gameplay can also be experienced using immersive Virtual Reality (VR). VR adds an additional spatial level and can further increase the engagement as well as vividness. To investigate the benefits of using VR for serious games targeting the learning of history, we developed a serious game for desktop-3D and VR. Our serious game puts a player into the role of a medieval miller’s apprentice. Following a situated learning approach, the learner operates a mill and interacts with several other characters. These agents discuss relevant facts of the medieval life, thus enabling the construction of knowledge about the life in medieval towns. An evaluation showed that the game in general was successful in increasing the user’s knowledge about the covered topics as well as their topic interest in history. Whether the immersive VR or the simple desktop version of the application was used did not have any influence on these results. Additional feedback was gathered to improve the game further in the future.

Abstract:
The widespread availability of smartphones facilitates the integration of digital, augmented reality (AR), and tangible augmented reality (TAR) learning environments into the classroom. A haptic aspect can enhance the user’s overall experience during a learning process. To investigate further benefits of using TAR for educational purposes, we compare a TAR and a smartphone learning environment with a traditional worksheet counterpart in terms of learning effectiveness, emotions, motivation, and cognitive load. 64 sixth-grade students from a German high school used one of the three conditions to learn about frog anatomy. We found no significant differences in learning effectiveness and cognitive load. The TAR condition elicited significantly higher positive emotions than the worksheet, but not the smartphone condition. Both digital learning environments elicited significantly higher motivation, in contrast to the worksheet. Thus, our results suggest that smartphone and TAR learning environments are equally beneficial for enhancing learning.

Abstract:
The alignment of virtual to physical surfaces is essential to improve symbolic input and selection in XR. Previous techniques optimized for efficiency can lead to inaccuracies. We investigate regression-based refinement techniques and introduce a surface accuracy eval-uation. The results revealed that refinement techniques can highly improve surface accuracy and show that accuracy depends on the gesture shape and surface dimension. Our reference implementation and dataset are publicly available.

}
Abstract:
Perceptions about AI influence the attribution of characteristics and the interaction with AI. To find out how workers imagine an AI they would like to work with and what characteristics they attribute to it, we asked 174 working individuals to draw an AI they would like to work with, to report five adjectives they associate with their drawing and to evaluate the drawn and three other, typical AI representations (e.g. robot, smartphone) either presented as male or female. Participants mainly drew humanoid or robotic AIs. The adjectives that describe AI mainly referred to the inner characteristics, capabilities, shape, or relationship types. Regarding the evaluation, we identified four dimensions (warmth, competence, animacy, size) that can be reproduced for male and female AIs and different AI representations. This work addresses diverse conceptions of AI in the workplace and shows that human-centered AI development is necessary to address the huge design space.

}
Abstract:
Virtual Reality (VR) allows us to replace our visible body with a virtual self-representation (avatar) and to explore its effects on our body perception. While the feeling of owning and controlling a virtual body is widely researched, how VR affects the awareness of internal body signals (body awareness) remains open. Forty participants performed moving meditation tasks in reality and VR, either facing their mirror image or not. Both the virtual environment and avatars photorealistically matched their real counterparts. We found a negative effect of VR on body awareness, mediated by feeling embodied in and changed by the avatar. Further, we revealed a negative effect of a mirror on body awareness. Our results indicate that assessing body awareness should be essential in evaluating VR designs and avatar embodiment aiming at mental health, as even a scenario as close to reality as possible can distract users from their internal body signals.
