    Designing Grocery Shopping Experiences for Virtual Reality
    Online grocery shopping offers time-saving efficiency and convenience, yet many people still prefer physical shopping for trust in food freshness and other sensory experiences. While online stores are evolving to offer new user experiences, such as supporting eco-friendly or ethical shopping, the desktop and mobile platforms limit the engagement of such experiences. Virtual Reality (VR) presents an opportunity to create immersive and rich grocery shopping experiences, closing the gap between the convenience of online shopping and the sensory experience of physical shopping. Yet, designing VR grocery stores remains relatively unexplored. In this paper, we investigate the long-term potential of VR grocery stores, focusing on meeting individual needs. Through a co-design workshop, participants brainstormed the design of product displays, in-shop navigation, shopping carts, social shopping, among others. Based on our findings, we provide design recommendations for future VR grocery shopping to develop meaningful alternatives to existing shopping experiences for groceries.

    Being in the Zone: Investigating the Effectiveness of In-Vehicle Multi-Sensory Affective Displays
    (ACM, 2024-06)
    Previous research highlights the benefits of affective interfaces in improving drivers’ emotional state and performance. This poster investigates the impact of a multisensory affective display, encompassing visual, auditory, and olfactory stimuli. A preliminary evaluation with eight participants in easy driving conditions informed scent intensity and placement adjustments. In a subsequent study under more challenging driving scenarios, the majority of participants (14 out of 20) reported minimal awareness of the system, while self-reported less skilled drivers perceived the system, experienced distractions and cognitive overload. Our findings suggest that the effects of multisensory affective displays on drivers vary and are influenced by driving difficulty, driver skill, and mental state, such as the state of flow. Future research is encouraged to explore novel interface designs that consider drivers' skills and cognitive states to adapt accordingly.

    Gaze into Fintech: Assessing the Influence of Financial Literacy on Interaction Behaviour Using Eyetracking
    (ACM, 2024-06) ;
    Andrin Benz
    Financial technology (fintech) has become more accessible to diverse users, including finance practitioners and non-experts. We conducted a usability test with six participants, evaluating a fintech app using eye-tracking technology for finance practitioners and non-finance experts. Our analysis revealed that participants with limited financial knowledge had difficulty understanding financial information and navigating the software, indicated by a higher revisitation rate on financial labels. We also observed higher cognitive overload or uncertainty among non-practitioners, evidenced by gaze-click discrepancies. These insights aim to inform the design of more accessible fintech applications.

    Factors contributing to the use of foresight reports in parliament - the German case
    This study investigates the factors influencing the effective use of public sector foresight reports in political decision-making, with a particular focus on the German parliamentary context. Utilizing the Technology Acceptance Model (TAM) as a theoretical framework, the research examines the perceived usefulness (PU), perceived ease of use (PEOU), attitude towards using (ATU), and behavioral intention to use (BIU) of foresight reports among German parliamentarians. The study extends TAM by incorporating specific contextual factors relevant to foresight in policymaking, such as participative foresight, the organizational setup of foresight units, and the actionability of insights. Through a Qualitative Comparative Analysis (QCA) approach, the paper aims to unravel the complex interplay between these factors and their impact on parliamentarians' willingness to integrate foresight reports into their legislative work. The current hypotheses suggest that participative foresight, perceived actionability of reports, and alignment with political ideologies significantly influence the acceptance and use of foresight in policy formulation. However, the data collection is still to be done. This research will contribute to the literature on public management and foresight studies by providing nuanced insights into the success factors and challenges associated with incorporating foresight reports into political decision-making processes. Additionally, the study will offer practical implications for enhancing the impact of foresight activities within the public sector, particularly in terms of report design, dissemination strategies, and stakeholder engagement.

    Zukunftssichere Loyalitätsprogramme - Loyalitätsprogramme sind im Aufwind, aber nicht gut verstanden
    (Institute for Marketing and Customer Insight, 2023) ; ;
    Loyalty programs are still primarily used as a marketing tool for acquisition and sales promotion. However, due to stricter data protection regulations, access to customer data through these programs is becoming increasingly important. The article includes a current market analysis from the German market, which show that the majority of loyalty programs are mainly used for hard benefits, such as discounts and cash. Customers are trained to be "Coupon Kings & Queens" and "bargain hunters." Genuine service promises, beyond discounts and deals, are found only in exceptional cases. From the perspective of customers and executives, soft and community benefits are becoming increasingly important. The survey indicates that loyalty programs have been primarily used for customer acquisition and less for actual retention. Levers for long-term successful management of loyalty programs focus here: A mix of hard, soft, and community benefits can be sensible to generate first-party data.
