論文アブストラクト： The craft of carpentry relies on joinery: the connections between pieces of wood to create multipart structures. In traditional woodworking, joints are limited to the manual chisel skills of the craftsperson, or to capabilities of the machines, which favorite 90° or 180° angle joints with no more than two elements. We contribute an interactive design process in which joints are generated digitally to allow for unrestricted beam connectors, then produced from Nylon-12 using selective laser sintering (SLS) 3D printing. We present our Generative Joinery Design Tool and demonstrate our system on a selection of stools. The paper exemplifies the potential of Digital Joinery to enhance carpentry by incorporating a hybrid and interactive level of design sophistication and affordances that are very hard to achieve with traditional skills and tools.
論文アブストラクト： We share a study on the public adoption the Chibitronics circuit sticker toolkit, an open source, commercially available hardware toolkit for learning and creating electronics on paper. We examine sales data over a two-and-a-half-year period from November 2013, when the kit was launched commercially, to June 2016. We also look at publicly available project documentation from users during this period. We find that the Chibitronics user community confounds norms for traditional technology-making communities, especially in gender demographics. We explore the artifacts and types of documentation produced by users to learn about the various backgrounds, values, and goals of subcommunities, which includes educators, Makers, and crafters. In particular, we focus on artifacts from the craft community as a surprising and distinctive subset of technology creators. The diversity in public engagement shows how paper electronics tools like Chibitronics can be an effective approach for engaging new and broader audiences to participate in technology creation.
論文アブストラクト： Prototyping devices with kinetic mechanisms, such as automata and robots, has become common in physical computing projects. However, mechanism design in the early-concept exploration phase is challenging, due to the dynamic and unpredictable characteristics of mechanisms. We present Mechanism Perfboard, an augmented reality environment that supports linkage mechanism design and fabrication. It supports the concretization of ideas by generating the initial desired linkage mechanism from a real world movement. The projection of simulated movement within the environment enables iterative tests and modifications in real scale. Augmented information and accompanying tangible parts help users to fabricate mechanisms. Through a user study with 10 participants, we found that Mechanism Perfboard helped the participant to achieve their desired movement. The augmented environment enabled intuitive modification and fabrication with an understanding of mechanical movement. Based on the tool development and the user study, we discuss implications for mechanism prototyping with augmented reality and computational support.
論文アブストラクト： We present PEP (Printed Electronic Papercrafts), a set of design and fabrication techniques to integrate electronic based interactivities into printed papercrafts via 3D sculpting. We explore the design space of PEP, integrating four functions into 3D paper products: actuation, sensing, display, and communication, leveraging the expressive and technical opportunities enabled by paper-like functional layers with a stack of paper. We outline a seven-step workflow, introduce a design tool we developed as an add-on to an existing CAD environment, and demonstrate example applications that combine the electronic enabled functionality, the capability of 3D sculpting, and the unique creative affordances by the materiality of paper.
