The authors present a new concept of digital gastronomy—Cornucopia, a futuristic cooking methodology based on digital technologies. They discuss how they have merged kitchen tools with science fiction and actual technologies to create this new design space for gastronomy. The Virtuoso Mixer, the Digital Fabricator and the Robotic Chef were conceptualized to enable more flexibility and control over each of the most important elements of cooking: mixing ingredients, modeling food shapes and transforming edible matter from one state to another. The authors discuss related work and ideas, present their designs and propose their vision for the emerging design space of digital gastronomy.
We present an augmented airbrush that allows novices to experience the art of spray painting. Inspired by the thriving field of smart tools, our handheld device uses 6DOF tracking; augmentation of the airbrush trigger; and a specialized algorithm to restrict the application of paint to a preselected reference image. Our device acts both as a physical spraying device and as an intelligent assistive tool, providing simultaneous manual and computerized control. Unlike prior art, here the virtual simulation guides the physical rendering (inverse rendering), allowing for a new spray painting experience with singular physical results. We present our novel hardware design, control software, and a user study that verifies our research objectives.
In this paper we explore human-computer interaction for carving, building upon our previous work with the FreeD digital sculpting device. We contribute a new tool design (FreeD V2), with a novel set of interaction techniques for the fabrication of static models: personalized toolpaths, manual overriding, and physical merging of virtual models. We also present techniques for fabricating dynamic models, which may be altered directly or parametrically during fabrication. We demonstrate a semi-autonomous operation and evaluate the performance of the tool. We end by discussing synergistic cooperation between human and machine to ensure accuracy while preserving the expressiveness of manual practice.
In this paper, we present an approach to combining digital fabrication and craft, emphasizing the user experience. While many researchers strive to enable makers to design and produce 3D objects, our research seeks to present a new fabrication approach to make unique, one-of-a-kind artifacts. To that end, we developed the FreeD, a hand-held digital milling device. The system is guided and monitored by a computer while preserving the maker's freedom to sculpt and carve, and to manipulate the work in many creative ways. Relying on a predesigned 3D model, the computer gets into action only when the milling bit risks the object's integrity, by slowing down the spindle's speed or by drawing back the shaft, while the rest of the time it allows complete gestural freedom. We describe the key concepts of our work and its motivation, present the FreeD's architecture and technology, and discuss two projects made with the tool.
Digital fabrication, and especially 3D printing, is an emerging field that is opening up new possibilities for craft, art and design. The process, however, has important limitations; in particular, digitally designed artifacts are intrinsically reproducible. In stark contrast, traditional craft artifacts are individually produced by hand. The authors combine digital fabrication and craft in their work involving object destruction and restoration: an intentionally broken crafted artifact and a 3D printed restoration. The motivation is not to restore the original work but to transform it into a new object in which both the destructive event and the restoration are visible and the re-assembled object functions as a memorial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
