CuddleConnect: Designing Child-Initiated Emotive Communication and Mediated Hugs for Remote ParentâChild Connection Abstract Children often experience emotional distress during periods of separation from their parents, while parents may feel guilt about their limited availability. Yet, existing remote parentâchild communication technologies rarely accommodate childrenâs communicative capacities or provide meaningful support for their agency. Thus, we present CuddleConnect, an interactive system that supports child-initiated, affective remote communication. […]

Forefeel the Move: Investigating Proprioceptive Feedback for Communicating Imminent Motions of Body-actuating Systems Abstract Systems actuating the body can proactively assist users in diverse tasks. However, unexpected body actuation may pose safety risks. We propose proprioceptive feedback to inform users about an imminent actuation before the system takes control. In a user study, we compare different proprioceptive cues that either interrupt or augment user motion […]

Privacy & Safety Challenges of On-Body Interaction Techniques Abstract On-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, and privacy and safety, using speculative scenarios and adversarial roleplaying to elicit insights. […]

HaptEx: Investigating Haptic Notification Channels for Exoskeletons Across Different Levels of Actuation Abstract Exoskeletons are increasingly deployed in real-world contexts, where communicating critical system states or unexpected events is important for effective interaction. Haptic feedback offers a direct communication channel, integrating naturally with the actuated body region. Yet, it remains unclear how well haptic feedback is perceived while the body is being actuated. In a […]

EmbroForm: Digital Fabrication of Soft Freeform Objects with Machine Embroidered Pull-up Strings Abstract Pull-up objects form 3D shapes by pulling a string routed through a 2D material, offering low-cost 2D fabrication and reversible transformation. However, existing approaches rely on origamic folding, which creates faceted, oftentimes rigid surfaces and requires manual pull-up string routing. We introduce EmbroForm, a digital fabrication pipeline for fully soft pull-up objects […]

Imaginary Joint: Proprioceptive Feedback for Virtual Body Extensions via Skin Stretch Abstract Virtual body extensions such as a wing or tail have the potential to offer users new bodily experiences and capabilities in virtual and augmented reality. To use these extensions as naturally as oneâs own bodyâparticularly for body parts that are normally hard to see, such as a tailâit is essential to provide proprioceptive […]

Move with Style! Enhancing Avatar Embodiment in Virtual Reality through Proprioceptive Motion Feedback Abstract In virtual reality (VR), users slip into a variety of roles, represented by a rich diversity of avatars that each exhibit specific visual attributes and motionstyles. While users can see their avatarâs motion in VR, they usually cannot feel it. To enhance avatar embodiment, we propose active proprioceptive feedback that aligns […]

GestureCoach: Rehearsing for Engaging Talks with LLM-Driven Gesture Recommendations Abstract This paper introduces GestureCoach, a system designed to help speakers deliver more engaging talks by guiding them to gesture effectively during rehearsal. GestureCoach combines an LLM-driven gesture recommendation model with a rehearsal interface that proactively cues speakers to gesture appropriately. Trained on expertsâ gesturing patterns from TED talks, the model consists of two modules: an […]

Texergy: Textile-based Harvesting, Storing, and Releasing of Mechanical Energy for Passive On-Body Actuation Abstract Humans instinctively manipulate and “actuate” their clothing, for instance, to adapt to the environment or to modify aesthetics. However, such manual actuation remains in exible and directly tied to user action. We introduce Texergy, a textile-based technical framework that decouples user input and actuated output to make passive on-body actuation interactive […]

Biomaterials for Prototyping in HCI Abstract While prototyping is a widespread practice among researchers, creating sustainable, functional devices remains challenging due to the limited range of available tools and materials. We present several approaches to sustainable prototyping of functional devices. Our methods range from using bio-based and bio-degradable materials as sustainable alternatives to biologically growing electronic substrates. These methods enable a new class of interactive […]
