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

This paper presents a narrative review of the current practices in assessing learners'
cognitive abilities and the limitations of traditional intelligence tests in capturing a …

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

We introduce Acoustruments: low-cost, passive, and power-less mechanisms, made from
plastic, that can bring rich, tangible functionality to handheld devices. Through a structured …

We describe Lamello, an approach for creating tangible input components that recognize
user interaction via passive acoustic sensing. Lamello employs comb-like structures with …

Capacitive multi-touch displays are not designed to detect passive objects placed on them-
in fact, these systems usually contain filters to actively reject such touch data. We present a …

Today's touchscreen devices commonly detect the coordinates of user input through
capacitive sensing. Yet, these coordinates are the mere 2D manifestations of the more …

This paper proposes user-customizable passive control widgets, called MagGetz, which
enable tangible interaction on and around mobile devices without requiring power or …

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 …
