Research

Our research focuses on innovative ways of seamlessly integrating digital media with the effective, expressive and engaging ways people interact in the physical world. Our goal is to make objects responsive, render surfaces and spaces interactive, and augment the human itself. To do so, we leverage cutting-edge technology, such as printed electronics, interactive paper, flexible and multiple displays. This yields novel interaction possibilities for which we design, implement and study user interfaces and interactive systems.

Digital Fabrication Technologies

ObjectSkin thumbnail

ObjectSkin

ObjectSkin is a fabrication technique for adding conformal interactive surfaces to everyday objects. It enables multi-touch sensing and display output that seamlessly integrates with highly curved and irregular geometries.

HotFlex thumbnail

HotFlex

HotFlex leverages printed embedded elements, capable of computer-controlled state change, to enable hands-on remodeling, personalization, and customization of a 3D-printed object after it is printed.

Foldio

Foldio is a new design and fabrication approach for custom interactive objects. The user defines a 3D model and assigns interactive controls; a fold layout containing printable electronics is auto-generated.

Flexibles

Flexibles add expressive deformation input to interaction with on-screen tangibles. Based on different types of deformation mapping, Flexibles can capture pressing, squeezing, and bending input with multiple levels of intensities.

Capricate

Capricate, is a fabrication pipeline that enables users to easily design and 3D print highly customized objects that feature embedded capacitive multi-touch sensing.

PrintScreen

PrintScreen is an enabling technology for digital fabrication of customized flexible displays using thin-film electroluminescence (TFEL).

PrintSense

A multimodal on-surface and near-surface sensing technique for planar, curved and flexible surfaces.

A Cuttable Multi-touch Sensor

In this project, we propose cutting as a novel paradigm for ad-hoc customization of printed electronic components. We contribute a printed capacitive multi-touch sensor, which can be cut by the end-user to modify its size and shape.

Body Interaction

Tacttoo

Tacttoo is a feel-through interface for electro-tactile output on the user’s skin. At less than 35μm in thickness, it is the thinnest tactile interface for wearable computing to date.

Multi-Touch Skin

Multi-Touch Skin are thin and flexible multi-touch sensors for on-skin input. They enable high-resolution multi-touch input on the body and can be customized in size and shape to fit various locations on the body.

FingerInput

FingerInput is a thumb-to-finger gesture recognition system using depth sensing and convolutional neural networks. It is the first system that accurately detects the touch points between fingers as well as the finger flexion.

DeformWear

DeformWear are tiny wearable devices that leverage single-point deformation input on various body locations. This enables expressive and precise input using high-resolution pressure, shear, and pinch deformations.

SkinMarks

SkinMarks are thin and conformal skin electronics for on-body interaction. They enable precisely localized input and visual output on strongly curved and elastic body landmarks.

iSkin

We propose iSkin, a novel class of skin-worn sensors for touch input on the body. iSkin is a very thin sensor overlay, made of biocompatible materials, and is flexible and stretchable.

More Than Touch

An elicitation study on how people interact on skin for controlling mobile devices. Investigates skin-specific input modalities, gestures and their associated mental modals, and preferred input locations.

On-Body Displays

On-body displays leverage instant availability and human physiology for personal and shared information display.

Flexible and Shape Displays
