For more than two decades, capacitive sensing has played a prominent role in human-
computer interaction research. Capacitive sensing has become ubiquitous on mobile …

We introduce Flexibles: 3D-printed flexible tangibles that are deformation-aware and
operate on capacitive touchscreens. Flexibles add expressive deformation input to …

Tactile maps support blind and visually impaired people in orientation and to familiarize with
unfamiliar environments. Interactive approaches complement these maps with auditory …

Tactile graphics play an essential role in knowledge transfer for blind people. The tactile
exploration of these graphics is often challenging because of the cognitive load caused by …

Tangibles on capacitive touchscreens are a promising approach to overcome the limited
expressiveness of touch input. While research has suggested many approaches to detect …

This work describes a novel building block system for tangible interaction design,
GaussBricks, which enables real-time constructive tangible interactions on portable …

The distinct properties and affordances of paper provide benefits that enabled paper to
maintain an important role in the digital age. This is so much so, that some pen–paper …

Tangible objects on capacitive multi-touch surfaces are usually only detected while the user
is touching them. When the user lets go of such a tangible, the system cannot distinguish …

Research has explored miniature radar as a promising sensing technique for the recognition
of gestures, objects, users' presence and activity. However, within Human-Computer …

We contribute SurfaceConstellations, a modular hardware platform for linking multiple
mobile devices to easily create novel cross-device workspace environments. Our platform …
