We present an approach to 3D printing custom optical elements for interactive devices
labelled Printed Optics. Printed Optics enable sensing, display, and illumination elements to …

Our present understanding of young children׳ s touch-screen performance is still limited, as
only few studies have considered analyzing children׳ s touch interaction patterns so far. In …

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

From zooming on smartphones and mid-air gestures to deformable user interfaces, thumb-
index pinching grips are used in many interaction techniques. However, there is still a lack of …

Hover, touch, and force are promising input modalities that get increasingly integrated into
screens and everyday objects. However, these interactions are often limited to flat surfaces …

We introduce the concept of tangibles that users can manipulate with their feet. We call them
kickables. Unlike traditional tangibles, kickables allow for very large interaction surfaces as …

There has been little discussion on how the materials used to create deformable devices,
and the subsequent interactions, might influence user performance and preference. In this …

We introduce UnicrePaint, a digital painting system that allows the user to paint with physical
objects by acquiring three parameters from the interacting object: the form, the color pattern …

We present PneuModule, a tangible interface platform that enables users to reconfigure
physical controls on pressure-sensitive touch surfaces using pneumatically-actuated …

Fluid User Interfaces (Fl. UIs) are liquid-based touch surfaces that use computer vision to
detect and interpret a range of tactile user inputs. While Fl. UIs have less input resolution …
