    Older adults, which are affected by neurological diseases such as dementia, often suffer from cognitive and motor deficits, and, therefore, require special care and therapy. However, especially during times of a global pandemic, they are a vulnerable highrisk group that has to be kept safe, which limits their possibilities to perform cognitive or motor training, or visit places outside their homes. We developed and evaluated a motor-cognitive exergame using a human-centered design approach, in which the older adults can virtually visit known places in their city of residence in omni-directional 3D-videos using immersive virtual reality (VR) technologies. The player's goal is to take pictures of famous landmarks with a tracked wearable that replicates a physical camera. We evaluated the game during a nine weeks user study with ten older adults with mild forms of dementia in a between-subject design: (i) five players experienced the game twice a week for 15-25 minutes, and (ii) five participants in a control group, who did not play the game. The results suggest that the overall well-being of players improved and that their game performance increased. Cognitive and physical tests indicate that the test group experiencing the game improved more than the control group. All players had positive attitudes towards the game and enjoyed the welcome change.

    User-Centered Design of Immersive Research Applications for Understanding Written Artefacts
    (The Eurographics Association, 2021) Gabel, Jenny; Berns, Christof; Bosch, Sebastian; Eickmeyer, Jost; Harter-Uibopuu, Kaja; Martin, Nathalie; Osthof, Ann Lauren; Steiger, Johann Anselm; Steinicke, Frank; Orlosky, Jason and Reiners, Dirk and Weyers, Benjamin
    Writing is an essential cultural technique that shaped our world's societies and is an important cultural heritage. The Cluster of Excellence 'Understanding Written Artefacts' is an interdisciplinary and cross-cultural long-term project dedicated to studying so-called 'Written Artefacts (WA)', which include all sorts of objects on which visual signs are applied by hand. Through our work, the research field of human-computer interaction is represented in the Cluster for the first time. This paper introduces our interdisciplinary research on immersive applications for understanding WA. We motivate the usage of virtual reality (VR) technologies for the novel field of WA research, in which we explore new immersive ways of studying WA. Currently, only fieldwork provides the spatial context to the WA in the inscribed spaces. Immersive applications could provide researchers with virtual access to the spatial and even temporal context at any time, but so far, VR has not been used in academia for this use case. We developed two immersive VR systems with a user-centred design approach in close cooperation with academic experts from ancient history, classical archaeology, and theology, among other fields. Our VR systems visualize WA with their temporal and spatial context and provide additional content such as reconstructions, hidden layers, and meta information. Our tool was developed for two different application scenarios, (1) a large outdoor scenario of the ancient Roman theatre of Miletus, and (2) an interior scenario of the church at the Rittergut Lucklum.
