WRLKit: Computational Design of Personalized Wearable Robotic Limbs Abstract Wearable robotic limbs (WRLs) augment human capabilities through robotic structures that attach to the user’s body. While WRLs are intensely researched and various device designs have been presented, it remains difficult for non-roboticists to engage with this exciting field. We aim to empower interaction designers and application domain experts to explore novel designs and applications by […]

Double-Sided Tactile Interactions for Grasping in Virtual Reality Abstract For grasping, tactile stimuli to multiple fingertips are crucial for realistic shape rendering and precise manipulation. Pinching is particularly important in virtual reality since it is frequently used to grasp virtual objects. However, the interaction space of tactile feedback around pinching is underexplored due to a lack of means to provide co-located but different stimulation to […]

Design and Fabrication of Body-Based Interfaces (Demo of Saarland HCI Lab) This Interactivity shows live demonstrations of our lab’s most recent work on body-based interfaces. The soft, curved and deformable surface of the human body presents unique opportunities and challenges for interfaces. New form factors, materials and interaction techniques are required that move past the conventional rigid, planar and rectangular devices and the corresponding interaction […]

FeatherHair Interacting with Sensorized Hair in Public Settings Human hair opens up new opportunities for embodied interactions that build on its unique physical affordances and location on the body. As hair has high socio-cultural significance, the design of hair interfaces is coupled with social and personal needs. Albeit this makes field investigations indispensable, they are missing from prior work. We present a fabrication approach for […]

I Need a Third Arm! Eliciting Body-based Interactions with a Wearable Robotic Arm Abstract Wearable robotic arms (WRA) open up a unique interaction space that closely integrates the user’s body with an embodied robotic collaborator. This space affords diverse interaction styles, including body movement, hand gestures, or gaze. Yet, it is so-far unexplored which commands are desirable from a user perspective. Contributing findings from an […]

Skill-Sleeves Designing Electrode Garments for Wearability Many existing explorations of wearables for HCI consider functionality first and wearability second. Typically, as the technologies, designs, and experiential understandings develop, attention can shift towards questions of deployment and wearability. To support this shift of focus we present a case study of the iterative design of electrode sleeves. We consider the design motivations and background that led to […]

PhysioSkin Rapid Fabrication of Skin-Conformal Physiological Interfaces Advances in rapid prototyping platforms have made physiological sensing accessible to a wide audience. However, off-the-shelf electrodes commonly used for capturing biosignals are typically thick, non-conformal and do not support customization. We present PhysioSkin, a rapid, do-it-yourself prototyping method for fabricating custom multi-modal physiological sensors, using commercial materials and a commodity desktop inkjet printer. It realizes ultrathin skin-conformal […]

On-Body Displays On-body displays transform the human skin into an interactive surface, enabling in-situ access to digital contents and leveraging human physiology for interaction. On-body displays stand in the tradition of static body augmentations, like tattoos and nail polish, but enhance them by interactive input and visual output. In this project, we focus on the human hand and forearm – a well-visible area that supports […]

DeformWear Deformation Input on Tiny Wearable Devices Due to their small surfaces, wearable devices make existing techniques for touch input very challenging. This paper proposes deformation input on a tiny and soft surface as an input modality for wearable computing devices. We introduce DeformWear, tiny wearable devices that leverage single-point deformation input on various body locations. Despite the small input surface, DeformWear enables expressive and […]

FingerInput Capturing Expressive Single-Hand Thumb-to-Finger Microgestures for On-Skin Input Single-hand thumb-to-finger microgestures have shown great promise for expressive, fast and direct interactions. However, pioneering gesture recognition systems each focused on a particular subset of gestures. We are still in lack of systems that can detect the set of possible gestures to a fuller extent. In this paper, we present a consolidated design space for thumb-to-finger […]
