a) Foldios are designed in 3D. Print&fold layouts are automatically generated, including customized printable electronics for sensing and output. The technique enables quick, easy and inexpensive fabrication of a wide variety of folded interactive objects, including b) UbiComp devices, c) actuated shape-changing objects and d) lightweight paper crafts.
