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. We…2026CSCarolin Stellmacher et al.University of BremenOne-Handed Operation & Mobile GesturesTouch Target Selection & PointingCHI
Determining Perception Thresholds for Real and Virtual Inclinations While Cycling in Virtual RealityIn virtual reality (VR) experiences, mismatches between reality and virtuality are usually undesirable, as they can disrupt immersion and induce cybersickness. However, when carefully controlled, they may expand the design space of VR. This research investigates perceptual detection thresholds for mismatches between r…2026JKJonas Keppel et al.University of Duisburg-EssenImmersion & Presence ResearchFitness Tracking & Physical Activity MonitoringMotion Sickness & Passenger ExperienceCHI
Privacy & Safety Challenges of On-Body Interaction TechniquesOn-body computing systems offer new forms of interaction, but while they are increasingly integrated into everyday contexts, their unique privacy and safety challenges remain understudied. This paper examines these challenges through a two-round interview study with $N = 15$ experts in human-computer interaction, an…2026DGDañiel Gerhardt et al.Helmholtz Center for Information SecurityContext-Aware ComputingPrivacy by Design & User ControlPrivacy Perception & Decision-MakingCHI
Connected Material Experiences using Bimanual Vibrotactile Crosstalk in Virtual RealityPerceiving material properties such as elasticity, flexibility, and torsion is inherently bimanual, as we rely on the relative motion of our hands to form a unified sense of materiality. Yet, most vibrotactile material rendering approaches are limited to a single hand or finger. While prior work has explored bimanual…2026NSNihar Sabnis et al.Max Planck InstituteIn-Vehicle Haptic, Audio & Multimodal FeedbackImmersion & Presence ResearchShape-Changing Interfaces & Soft Robotic MaterialsCHI
Delusionized? Potential Harms of Proprioceptive Manipulations through Hand Redirection in Virtual RealityTo enhance interactions in VR, hand redirection (HR)-based illusion techniques apply offsets between the virtual and real-world position of users’ hands. While adaptation to such HR offsets is recognized, their impact on proprioception accuracy remains unexplored. However, deploying HR without understanding its potent…2025MFMartin Feick et al.German Research Center for Artificial IntelligenceHaptic WearablesHand Gesture RecognitionUIST
Predicting the Limits: Tailoring Unnoticeable Hand Redirection Offsets in Virtual Reality to Individuals’ Perceptual BoundariesMany illusion and interaction techniques in Virtual Reality (VR) rely on Hand Redirection (HR), which has proved to be effective as long as the introduced offsets between the position of the real and virtual hand do not noticeably disturb the user experience. Yet calibrating HR offsets is a tedious and time-consuming…2024MFMartin Feick et al.German Research Center for Artificial IntelligenceFull-Body Interaction & Embodied InputEye Tracking & Gaze InteractionBrain-Computer Interface (BCI) & NeurofeedbackUIST
Touching the Moon: Leveraging Passive Haptics, Embodiment and Presence for Operational Assessments in Virtual RealitySpace agencies are in the process of drawing up carefully thought-out Concepts of Operations (ConOps) for future human missions on the Moon. These are typically assessed and validated through costly and logistically demanding analogue field studies.

Beyond the Blink: Investigating Combined Saccadic & Blink-Suppressed Hand Redirection in Virtual RealityIn pursuit of hand redirection techniques that are ever more tailored to human perception, we propose the first algorithm for hand redirection in virtual reality that makes use of saccades, i.e., fast ballistic eye movements that are accompanied by the perceptual phenomenon of change blindness. Our technique combines…2024AZAndré Zenner et al.German Research Center for Artificial IntelligenceHand Gesture RecognitionFull-Body Interaction & Embodied InputEye Tracking & Gaze InteractionCHI
The Impact of Avatar Completeness on Embodiment and the Detectability of Hand Redirection in Virtual RealityTo enhance interactions in VR, many techniques introduce offsets between the virtual and real-world position of users’ hands. Nevertheless, such hand redirection (HR) techniques are only effective as long as they go unnoticed by users—not disrupting the VR experience.
