PublicationDark Patterns: manipulative Designstrategien in digitalen Gesundheitsanwendungen( 2024-02-08)
;Mildner, ThomasMalaka, RainerAmong other things, digital health applications offer users support in better understanding their physical and mental health through digital data, thereby promoting positive health behavior. In addition to state-approved digital health applications (DiGA) and digital care applications (DiPA), there is a wide array of other commercial health applications available to users. Particularly in non-approved applications, developers often deploy manipulative design strategies (dark patterns), intentionally or unintentionally, to deceive users into making specific decisions. This article provides an overview of current and widespread dark patterns and assesses the risks posed by them in digital health applications. In the future, “light” should be shed on dark patterns by creating more transparency for users, providing regulators with a more accurate understanding of dark patterns, and paying more attention to the implementation of guidelines. Thus, users may gain autonomy using healthcare applications and their data can be better protected.Type: journal articleJournal: Bundesgesundheitsblatt (2024) -

PublicationListening to the Voices: Describing Ethical Caveats of Conversational User Interfaces According to Experts and Frequent Users( 2024)
;Cooney, Orla ;Doyle, Philip ;Garaialde, Diego ;Clark, Leigh ;Sloan, John ;Wenig, Nina ;Mildner, Thomas ;Meck, Anna-MariaBartl, MarionAdvances in natural language processing and understanding have led to a rapid growth in the popularity of conversational user interfaces (CUIs). While CUIs introduce novel benefits, they also yield risks that may exploit people's trust. Although research looking at unethical design deployed through graphical user interfaces (GUIs) established a thorough understanding of so-called dark patterns, there is a need to continue this discourse within the CUI community to understand potentially problematic interactions. Addressing this gap, we interviewed 27 participants from three cohorts: researchers, practitioners, and frequent users of CUIs. Applying thematic analysis, we construct five themes reflecting each cohort's insights about ethical design challenges and introduce the CUI Expectation Cycle, bridging system capabilities and user expectations while considering each theme's ethical caveats. This research aims to inform future development of CUIs to consider ethical constraints while adopting a human-centred approach.Type: conference paper -
PublicationMobile Map Applications for Foldable Devices( 2024)
;Jana WahlsAs foldable mobile devices grow in popularity, they often feature two screens-a smaller cover screen and a larger inside one, accessible by unfolding the device vertically or horizontally. Despite this, most mobile applications, including map apps, have yet to be fully optimised for these interfaces. This paper explores adaptations of mobile map applications for foldable mobile devices to enhance usability and user satisfaction. In a user study with nine participants, we identify key aspects of mobile map app design for exploration and navigation scenarios. Our results show that in navigation scenarios, screens should provide complementary information, with turn-by-turn instructions on one screen and a route overview on the other. Furthermore, our results show that map views should maintain map alignment and orientation across screens during exploration to prevent disorientation. Ultimately, we find that the success of mobile maps on foldable devices rests on the role and importance of context and user preference in mobile map interactions. Foldable devices offer a valuable chance of improving the mobile map experience on mobile devices if designers find useful ways to make use of the two screens and the increase screen real estate.Type: conference paper -
PublicationDesigning Grocery Shopping Experiences for Virtual RealityOnline 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.Type: conference paper

PublicationAbout Engaging and Governing Strategies: A Thematic Analysis of Dark Paterns in Social Networking Services( 2023-04)
;Mildner, Thomas ;Doyle, Philip ;Cowan, BenjaminMalaka, RainerResearch in HCI has shown a growing interest in unethical design practices across numerous domains, often referred to as "dark patterns". There is, however, a gap in related literature regarding social networking services (SNSs). In this context, studies emphasise a lack of users' self-determination regarding control over personal data and time spent on SNSs. We collected over 16 hours of screen recordings from Facebook's, Instagram's, TikTok's, and Twitter's mobile applications to understand how dark patterns manifest in these SNSs. For this task, we turned towards HCI experts to mitigate possible difculties of non-expert participants in recognising dark patterns, as prior studies have noticed. Supported by the recordings, two authors of this paper conducted a thematic analysis based on previously described taxonomies, manually classifying the recorded material while delivering two key fndings: We observed which instances occur in SNSs and identifed two strategies-engaging and governing-with fve dark patterns undiscovered before.
