Pre-eating Play: Fabrication Experiences for Playful Human–Food Interaction Michinari Kono, Norio Sasaki, Osamu Kabashima, Junichi Yamaoka

Recent progress ofhuman–food interaction (HFI) has led to a growing interest in the merger of digital technologies for playful experiences in eating. Although these interactive technologies have been primarily integrated with eating experiences, we find that progress has also been made in digital food fabrication process in the human–computer interaction (HCI) field. Food fabrication techniques are used to expand the design space of food preparation, and it is accomplished before the eating stage. Many products have introduced playful experiences to this preparation stage. However, we have not yet explored food fabrication techniques in the context of play in depth. This paper discusses the food preparation stage and how it can be designed to be playful by introducing several product cases. Using this knowledge, we further discuss how such methods can be applied to previous digital food fabrication techniques with our own example ofa playful food fabrication approach. We aim to enable various stages of human–food interaction to be more playful by understanding food as a toy-like object that can be independent from or related to the eating stage.

FoldTronics: Creating 3D Objects with Integrated Electronics Using Foldable Honeycomb Structures

FoldTronics is a 2D-cutting based fabrication technique to integrate electronics into 3D folded objects. The key idea is to cut and perforate a 2D sheet to make it foldable into a honeycomb structure using a cutting plotter; before folding the sheet into a 3D structure, users place the electronic components and circuitry onto the sheet.

The fabrication process only takes a few minutes enabling users to rapidly prototype functional interactive devices. The resulting objects are lightweight and rigid, thus allowing for weight-sensitive and force-sensitive applications. Finally, due to the nature of the honeycomb structure, the objects can be folded flat along one axis and thus can be efficiently transported in this compact form factor.

We describe the structure of the foldable sheet, and present a design tool that enables users to quickly prototype the desired objects. We showcase a range of examples made with our design tool, including objects with integrated sensors and display elements.
