Tactum: A Skin-Centric Approach to Digital Design and Fabrication – a paper by Madeline Gannon of MADLAB.CC and Tovi Grossman & George Fitzmaurice of Autodesk Research – has been accepted for publication in this year's Association for Computing Machinery’s (ACM) CHI conference. It has also been awarded a best paper honorable mention this year.
The paper will be presented in room 401 of the Coex Convention Center on Tuesday, April 21, 2015 at 16:30 - 17:50.
Skin-based input has become an increasingly viable interaction model for user interfaces, however it has yet to be explored outside the domain of mobile computing. In this paper, we examine skin as an interactive input surface for gestural 3D modeling-to-fabrication systems. When used as both the input surface and base canvas for digital design, skin-input can enable non-experts users to intuitively create precise forms around highly complex physical contexts: our own bodies. In this paper, we outline design considerations when creating interfaces for such systems. We then discuss interaction techniques for three different modes of skin-centric modeling: direct, parametric, and generative. We also present Tactum, a new fabrication-aware design system that captures a user’s skin-centric gestures for 3D modeling directly on the body. Lastly, we show sample artifacts generated with our system, and share a set of observations from design professionals.
