Easigami: a reconfigurable folded-sheet TUI

ABSTRACT

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.
