The growing makers’ community demands better supports for designing and fabricating interactive functional objects. Most of the current approaches focus on embedding desired functions within new objects. Instead, we advocate repurposing the existing objects and rapidly authoring interactive functions onto them. We present Plain2Fun, a design and fabrication pipeline enabling users to quickly transform ordinary objects into interactive and functional ones. Plain2Fun allows users to directly design the circuit layouts onto the surfaces of the scanned 3D model of existing objects. Our design tool automatically generates as short as possible circuit paths between any two points while avoiding intersections. Further, we build a digital machine to construct the conductive paths accurately. With a specially designed housing base, users can simply snap the electronic components onto the surfaces and obtain working physical prototypes. Moreover, we evaluate the usability of our system with multiple use cases and a preliminary user study.
