Our group is embarking on an effort to enhance fabrication technology, both through the use of new and better materials and in its ease of program. Much of our effort here is on embedding standard programming capabilities such as testability, modularity, iterability, and version control into the design and fabrication process.

Volunteer AT Fabricators

Perry-Hill, J., Shi, P., Mankoff, J. & Ashbrook, D. Understanding Volunteer AT Fabricators: Opportunities and Challenges in DIY-AT for Others in e-NABLE. Accepted to CHI 2017 We present the results of a study of e-NABLE, a distributed, collaborative volunteer effort to design and fabricate upper-limb assistive technology devices for limb-different users. Informed by interviews with […]

Tactile Interfaces to Appliances

Facade is a crowdsourced fabrication pipeline to automatically generate tactile interfaces to appliances for blind people.

3D Printing with Embedded Textiles

Stretching the Bounds of 3D Printing with Embedded Textiles Textiles are an old and well developed technology that have many desirable characteristics. They can be easily folded, twisted, deformed, or cut; some can be stretched; many are soft. Textiles can maintain their shape when placed under tension and can even be engineered with variable stretching […]

Printable Adaptations

Reprise: A Design Tool for Specifying, Generating, and Customizing 3D Printable Adaptations on Everyday Objects Reprise is a tool for creating custom adaptive 3D printable designs for making it easier to manipulate everything from tools to zipper pulls. Reprise’s library is based on a survey of about 3,000 assistive technology and life hacks drawn from […]

A Knitting Machine Compiler

  Although industrial knitting machines can automatically produce a wide range of garments, they are programmed through onerous means such as pixel level image manipulation. This limits the potential for automation of knitted object design, re-use of object components, and narrows the audience able to design for these machines. Our contribution is a visual design […]

RapID — interactive RFID

RapID – A framework for fabricating low-latency interactive objects with RFID tags RFID tags can be used to add inexpensive, wireless, batteryless sensing to objects. However, quickly and accurately estimating the state of an RFID tag is difficult. In this work, we show how to achieve low-latency manipulation and movement sensing with off-the-shelf RFID tags […]

Image of embroidery machine head playing the Threadsteading game


In work done collaboratively with Disney Research Pittsburgh and led by Gillian Smith of Northeastern we explored a multi-player game that can be embedded into a quilting and/or embroidery machine interface. Gameplay is constrained by the fact that only a single thread of fabric can be drawn over time. Players compete to ‘scout’ over a map […]

3D printed attachments

Encore: 3D printed attachments What happens when you want to 3D print something that must interact with the real world? The Encore project makes it possible to 3D print objects that must attach to things in the real world. Encore provides an interface that, given an imported object and a chosen attachment method, visualizes metrics relating the goodness […]

Helping Hands

Prosthetic limbs and assistive technology (AT) require customization and modification over time to effectively meet the needs of end users. Yet, this process is typically costly and, as a result, abandonment rates are very high. Rapid prototyping technologies such as 3D printing have begun to alleviate this issue by making it possible to inexpensively, and […]
