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 of thin flat polygon pieces connected
by electronically instrumented hinges. Using the Easigami
TUI as an input device, we have developed early prototype
applications to develop children’s visualization and spatial
recognition skills. We discuss our experience in integrating
traditional craft with computation, which may inform future
tangible and graspable user interface design.
