    Elevating Stress Levels - Exploring Multimodality for Stress Induction in VR
    (Mensch und Computer 2022 - Tagungsband, 2022) Weiß, Sebastian; Kimmel, Simon; Withöft, Ani; Jung, Frederike; Boll, Susanne; Heuten, Wilko
    Simulation training in Virtual Reality (VR) has gained attraction in recent years. With its broad application possibilities and implicit safety for users, simulation-based training may be imagined for safety-critical situations and exposure therapy. Beyond visual and auditory representation of the environment and stressors, upcoming hardware supports olfactory and haptic feedback. To examine the benefits of these technological advances in stress training, we present a Wizard of Oz pilot study (N=12). Therein, a bimodal presentation of the scenario ‘being stuck in an elevator’ was compared to a multimodal one. For the comparison, we measured qualitative feedback, the iGroup presence questionnaire scores, and physiological stress reactions by recording changes in cardiac and pulmonary activity. Results show trends for moderately more pronounced stress levels and perceived presence for the multimodal presentation. Thus, we argue that multimodal stress induction may better simulate hazardous situations in stress training.

    Informed ShoppAR - Visualizing Privacy Information in Augmented Reality
    (Mensch und Computer 2022 - Tagungsband, 2022) Kaiser, Jonah-Noël; Marianski, Thu; Jung, Frederike; Woźniak, Mikołaj; Boll, Susanne
    Personal informatics devices, such as fitness trackers, become increasingly popular. When selecting a product in store, users do not only make a decision about a product’s functionality. Beyond what is written on the packaging, a purchase also decides about which consumer data will be collected, how it will be used and with whom it will be shared. Privacy policies and terms and conditions inform users before the initial product usage. Many do not read these texts and remain unaware of what they agreed to. With this paper we argue that privacy information should be shown before purchasing a device. We explore how Augmented Reality (AR) may be used to facilitate informed decision-making. We implemented and evaluated the user experience of an AR app in a mock-up electronics store. Our results highlight the potential of AR visualizations for displaying privacy information in a purchasing context.
