We present Silicone iLluminated Active Peripherals (SLAP), a system of tangible, translucent
widgets for use on multitouch tabletops. SLAP Widgets are cast from silicone or made of …

Touch input is dominantly detected using mutual-capacitance sensing, which measures the
proximity of close-by objects that change the electric field between the sensor lines. The …

We introduce and formally evaluate smartcasting: a smartphone-based Ray Casting
implementation for 3D environments presented on large, public, autostereoscopic displays …

Multi-touch interactions are a promising means of control for interactive tabletops. However,
a lack of precision and tactile feedback makes multi-touch controls a poor fit for tasks where …

Multi-touch user interfaces (MTUIs) can represent a valuable tool for enhancing human-
machine interaction. The naturalness and variety of hand gestures offer a more direct and …

We present an interactive virtual percussion instrument system, Tabletop Ensemble, that can
be used by a group of collaborative users simultaneously to emulate playing music in real …

This paper describes how the development of a tangible multi-touch surface, Bricktable, was
made possible through the use of open-source communities and tools. Subsequent work …

In this paper, we introduce a direct manipulation tabletop multi-touch user interface for
spatial audio scenes. Although spatial audio rendering exists for several decades now …

This paper explores the evolution of collaborative, multi-user, musical interfaces developed
for the Bricktable interactive surface. Two key types of applications are addressed: user …

Early attempts at supporting interaction with digital products for the design review were
based on CAD and virtual reality (VR) systems. However, it is not easy to build a virtual …
