Many types of tangible interaction systems, such as interactive surfaces and gesture-based interfaces, are based on various kinds of optical tracking, using infrared illuminators and cameras. One drawback of these setups is that they suffer from ...

Graphs are a versatile representation of many systems in computer science, the social sciences, and mathematics, but graph theory is not taught in schools. We present our work on Graphmaster, a computationally enhanced construction kit that enables ...

Many research efforts today explore how digitally augmented tables enable face-to-face interaction with digital content and applications. Yet the design of digital tables is still largely driven by the constraints and requirements of the underlying ...

Easigami is a novel tangible user interface (TUI) and interactive system intended to help children to learn to fold 3D geometric forms and to explore 2D-3D transformations. We present the design of Easigami's physical interface: a reconfigurable system ...
