    Generating an Environment for Socializing Between Older Adults in a VR Supermarket

    Socialization is crucial for the well-being of individuals, but elderly people often face challenges due to physical and psychological issues, as well as the COVID-19 pandemic. To address this issue, a novel approach has been developed using a Japanese Virtual Reality (VR) supermarket, where older adults can purchase products that could be delivered to their homes while socializing with others in a familiar environment. The VR supermarket is based on Japanese supermarket shelf layouts, with hand-tracking and gestures used for interaction. Avatars, attached with images of the participants and their synchronized voice input are used to represent them. In a user study involving 14 older adults, the application was found to be effective for social communication, and potential negative effects such as cybersickness were successfully mitigated. The VR supermarket thus provides a valuable tool for older adults to socialize and meet their need to interact with people from the same age group, even in isolation (pandemic scenario).

    Teaching Optical Principles in XR
    (INFORMATIK 2023 - Designing Futures: Zukünfte gestalten, 2023) Zengerle, Tobias; Plecher, David A.; Flegr, Salome; Kuhn, Jochen; Fischer, Martin R.
    Extended Reality (XR) is seeing a massive rise in interest for the use in educational contexts, with a number of studies pointing out the beneficial effects on learning outcome when using immersive XR platforms, compared to classic educational approaches. However, since the necessary hardware has only recently become more accessible and consumer-level XR is just now beginning to push towards more widespread use, these technologies have not yet fully arrived in everyday university teaching. In this work, we will explore how modern XR technologies can be utilized to create new types of gaining knowledge and investigate how they can enhance the learning experience in actual everyday university practice. To this end, we entered into a cooperation with a chair of physics education (LMU) and developed an immersive Virtual Reality (VR) application for their optical physics lab course for students of human medicine. A usability study with a small number of participants yielded a very strong System Usability Score of 82.52, indicating that the resulting application is easy to use and highly accessible, even to users without prior VR experience and putting it in a great spot to be used in future university teaching.
