Personal fabrication machines, such as 3D printers and laser cutters, are becoming increasingly ubiquitous. However, designing objects for fabrication still requires 3D modeling skills, thereby rendering such technologies inaccessible to a wide user-group. In this paper, we introduce MixFab, a mixed-reality environment for personal fabrication that lowers the barrier for users to engage in personal fabrication. Users design objects in an immersive augmented reality environment, interact with…

A Desktop 3D Modeling System Controllable by Mid-air Interactions
TLDR
A 3D modeling system allowing users to easily design a new product by directly comparing a graphical model to a real product without scanning the real one is proposed.
Barriers to End-User Designers of Augmented Fabrication
TLDR
The results of a study of fifteen novice end users in an augmented fabrication design task are reported, and obstacles encountered in four contexts are discussed: capturing information about physical objects, transferring information to 3D modeling software, digitally modeling a new object, and evaluating whether the new object will work when fabricated.
Printy3D: in-situ tangible three-dimensional design for augmented fabrication
Three-dimensional design software is challenging for novices and non-experts; when working with objects that already exist, the task becomes even more difficult. We present Printy3D, a system that
RoMA: Interactive Fabrication with Augmented Reality and a Robotic 3D Printer
TLDR
The Robotic Modeling Assistant (RoMA), an interactive fabrication system providing a fast, precise, hands-on and in-situ modeling experience, lets users integrate real-world constraints into a design rapidly, allowing them to create well-proportioned tangible artifacts or to extend existing objects.
Interacting with personal fabrication devices
TLDR
Why today’s interaction model for personal fabrication tools is not suitable for non-technical users is illustrated and how solutions developed by human-computer interaction researchers over the last decades can be applied to this new domain is illustrated.
DesignAR: Immersive 3D-Modeling Combining Augmented Reality with Interactive Displays
TLDR
The combination of high-resolution, high-precision interactive surfaces with carefully aligned AR views opens up exciting possibilities for future work and design environments, a vision the authors call Augmented Displays.
Tactum: A Skin-Centric Approach to Digital Design and Fabrication
TLDR
This paper examines skin as an interactive input surface for gestural 3D modeling-to-fabrication systems, and presents Tactum, a new fabrication-aware design system that captures a user's skin-centric gestures for3D modeling directly on the body.
Making Fabrication Real: Fabrication for Real Usage, with Real Objects, by Real People
TLDR
This thesis research focuses on developing fabrication techniques with design tool integration to enable users to expressively create designs that can be attached to and function with existing real-world objects.
SPATA: Spatio-Tangible Tools for Fabrication-Aware Design
TLDR
SPATA is the digital adaptation of two spatial measurement tools, that explores their closer integration into virtual design environments, and adapt two of the traditional measurement tools: calipers and protractors.
Fabbed to Sense: Integrated Design of Geometry and Sensing Algorithms for Interactive Objects
TLDR
This dissertation investigates how 2D and 3D models for input devices can be automatically generated or modified in order to employ standard, off-the-shelf sensing techniques for adding interactivity to those objects, called ``fabbing to sense.

This work explores the design space of using direct finger input in conjunction with a deformable physical prop for the creation and manipulation of conceptual 3D geometric models in an extension of the types of manipulations one would perform on traditional modeling media.
FingARtips: gesture based direct manipulation in Augmented Reality
TLDR
This paper uses image processing software and finger- and hand-based fiducial markers to track gestures from the user, stencil buffering to enable the user to see their fingers at all times, and fingertip-based haptic feedback devices to enableThe user to feel virtual objects.

TLDR
The possibility to perform non-trivial tasks using only a few well-known hand gestures, so that almost no training is necessary to interact with 3D-softwares is shown.

TLDR
It is argued that construction toys, suitably instrumented or sensed, could be the inspiration for a new generation of easy-to-use, tangible modeling systems—especially if the tangible modeling is combined with graphical-interpretation techniques for enhancing nascent models automatically.
