PhysioSkin

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

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

DeformWear

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

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 […]

Grasping Microgestures

Grasping Microgestures

Grasping Microgestures Eliciting Single-hand Microgestures for Handheld Objects Our work informs gestural interaction with computer systems while hands are busy holding everyday objects. We present results from the first empirical analysis of over 2,400 microgestures performed by end-users. We call those gestures as Grasping Microgestures. Our key finding is to answer how grasps and object geometries affect the design space of microgestures performed on handheld […]

Like a Second Skin

Like a Second Skin Understanding How Epidermal Devices Affect Human Tactile Perception The emerging class of epidermal devices opens up new opportunities for skin-based sensing, computing, and interaction. Future design of these devices requires an understanding of how skin-worn devices affect the natural tactile perception. In this study, we approach this research challenge by proposing a novel classification system for epidermal devices based on flexural […]

Tacttoo

Tacttoo

Tacttoo A Thin and Feel-Through Tattoo for On-Skin Tactile Output Tacttoo is a feel-through interface for electro-tactile output on the user’s skin. Integrated in a temporary tattoo with a thin and conformal form factor, it can be applied on complex body geometries, including the fingertip, and is scalable to various body locations. At less than 35μm in thickness, it is the thinnest tactile interface for […]

Multi-Touch Skin

Multi-Touch Skin

Multi-Touch Skin A Thin and Flexible Multi-Touch Sensor for On-Skin Input Skin-based touch input opens up new opportunities for direct, subtle, and expressive interaction. However, existing skinworn sensors are restricted to single-touch input and limited by a low resolution. We present the first skin overlay that can capture high-resolution multi-touch input. Our main contributions are: 1) Based on an exploration of functional materials, we present […]

SkinMarks

SkinMarks

SkinMarks Enabling Interactions on Body Landmarks Using Conformal Skin Electronics The body provides many recognizable landmarks due to the underlying skeletal structure and variations in skin texture, elasticity, and color. The visual and spatial cues of such body landmarks can help in localizing on-body interfaces, guide input on the body, and allow for easy recall of mappings. Our main contribution are SkinMarks, novel skin-worn I/O […]
