Understanding How Mobile Interactions Shape Grasp and Contact Patterns Beyond the TouchscreenThe way users hold a smartphone depends on the interaction task, yet little is known about the fingers' engagement with the device's surfaces beyond the touchscreen. Such an understanding not only opens up opportunities for novel on- and off-screen interactions, but also the device’s possible physical affordances.

UrbAI: Exploring the Possibilities of Generative AI Image Processing to Promote Citizen ParticipationGiving citizens a voice in urban development processes is crucial for enabling socially sustainable cities and communities. However, citizens' opportunities to express ideas are often limited to communication channels that offer poor incentives for participation. In this paper, we conducted an in-the-wild technology p…2025APAdrian Preussner et al.University of St GallenGenerative AI (Text, Image, Music, Video)Community Engagement & Civic TechnologyCHI
LifeInsight: Design and Evaluation of an AI-Powered Assistive Wearable for Blind and Low Vision People Across Multiple Everyday Life ScenariosAssistive technologies (ATs) have the potential to empower blind and low vision (BLV) people. Yet, they often remain underutilised due to their immobility and limited applicability across scenarios. This paper presents LifeInsight, an AI-powered assistive wearable for BLV people that uses a wearable camera, microphone…2025FMFlorian Mathis et al.University of EdinburghHaptic WearablesVisual Impairment Technologies (Screen Readers, Tactile Graphics, Braille)CHI
Describing Explored Places through OpenStreetMap DataMobile navigation applications are good at providing efficient navigation instructions. However, they currently lack the capability to facilitate free exploration. Therefore, users are limited to encountering only places close to the shortest paths, neglecting places that could diversify navigation and foster spatia…2025ESEve Schade et al.University of St GallenGeospatial & Map VisualizationPublic Transit & Trip PlanningCHI
DIY Digital Interventions: Behaviour Change with Trigger-Action ProgrammingWhether it is sleep, diet, or procrastination, changing behaviours can be challenging. Individuals could design and build their own personalised digital interventions to help them reach their goals, but little is known about this process. Building upon previous research we propose the Behaviour Change with Trigger-Act…2024ASAva Elizabeth Scott et al.University College LondonCreative Collaboration & Feedback SystemsKnowledge Worker Tools & WorkflowsMobileHCI
MoodShaper: A Virtual Reality Experience to Support Managing Negative EmotionsNegative emotions such as sadness or anger are often seen as something to be avoided. However, recognising, processing and regulating challenging emotional experiences can facilitate personal growth and is essential for long-term well-being. To support people in regulating and reflecting on negative emotions, we desig…2024NWNadine Wagener et al.University of BremenImmersion & Presence ResearchVR Medical Training & RehabilitationMental Health Apps & Online Support CommunitiesDIS
Exploring Mobile Devices as Haptic Interfaces for Mixed RealityDedicated handheld controllers facilitate haptic experiences of virtual objects in mixed reality (MR). However, as mobile MR becomes more prevalent, we observe the emergence of controller-free MR interactions. To retain immersive haptic experiences, we explore the use of mobile devices as a substitute for specialised…2024CSCarolin Stellmacher et al.University of BremenShape-Changing Interfaces & Soft Robotic MaterialsMixed Reality WorkspacesCHI
Playing with Perspectives and Unveiling the Autoethnographic Kaleidoscope in HCI – A Literature Review of AutoethnographiesAutoethnography is a valuable methodological approach bridging the gap between personal experiences and academic inquiry, enabling researchers to gain deep insights into various dimensions of technology use and design.

Experiencing Dynamic Weight Changes in Virtual Reality Through Pseudo-Haptics and Vibrotactile FeedbackVirtual reality (VR) objects react dynamically to users' touch interactions in real-time. However, experiencing changes in weight through the haptic sense remains challenging with consumer VR controllers due to their limited vibrotactile feedback. While prior works successfully applied pseudo-haptics to perceive absol…2024CSCarolin Stellmacher et al.University of BremenVibrotactile Feedback & Skin StimulationForce Feedback & Pseudo-Haptic WeightCHI

Children with ADHD and their Care Ecosystem: Designing Beyond SymptomsDesigning for children with ADHD has been of increasing interest to the HCI community. However, current approaches do not adequately involve all relevant stakeholders, and primarily focus on addressing symptoms, following a medical model of disability that is extrinsic to neurodivergent interests.
