Summary: Many interactive devices use both machine elements and sensors,
simultaneously but redundantly enabling and measuring the same physical
function. We present Steel-Sense, an approach to joining these two families of
elements to create a new type of HCI design primitive. We leverage recent
developments in 3D printing to embed sensing in metal structures that are
otherwise difficult to equip with sensors, and present four design principles,
implementing (1) an electronic switch integrated within a ball bearing; (2) a
voltage divider within a gear; (3) a variable capacitor embedded in a hinge;
and (4) a pressure sensor within a screw. Each design demonstrates a different
sensing principle, and signals its performance through (1) movement; (2)
position; (3) angle (4) or stress. We mirror our elements physical performance
in a virtual environment, evaluate our designs electronically and structurally,
and discuss future work and implications for HCI research.

Summary: The digital design space, unlimited by its virtual freedom, differs from
traditional craft, which is bounded by a fixed set of given materials. We study
how to introduce parametric design tools to craftspersons. Our hypothesis is
that the arrangement of parametric design in modular representation, in the
form of a catalog, can assist makers unfamiliar with this practice. We evaluate
this assumption in the realm of bag design, through a Honeycomb Smocking
Pattern Catalog and custom Computer-Aided Smocking (CAS) design software. We
describe the technical work and designs made with our tools, present a user
study that validates our assumptions, and conclude with ideas for future work
developing additional tools to bridge computational design and craft.

Summary: People have been making things for a long time, yet digital making has
developed mostly within an industrial context. We question how non-digital
craft cultures can inform the design of digital tools. Furthermore, what
methods can help us understand these cultures in ways that are relevant to
digital practice? As makers ourselves, we see potential for collaborative
making to mitigate barriers in communication and provide insight into
non-digital practices and values. To evaluate this approach, we visited a
hunter-gatherer community that preserves an ancient craft, bringing with us
digital design and fabrication tools. Working together, we merged digital tools
with ostrich eggshell jewelry craft. We use this experience to draw conclusions
about making as a form of communication, the importance of supporting
appropriation and immediacy in collaborations, the challenge of combining
abstract design tools with concrete approaches, and the value of incorporating
design and making into communal life.

Summary: We introduce D-Coil, a new digital 3D modeling approach using wax coiling to
bring tangibility to the design of digital models. After defining a shape to
extrude, the users follow the lead of a hand-held actuated extruder to
instantiate the actual extrusion using wax. The tangibility of the wax
extrusion sets the stage to create the next components until the digital model
is completed. The digital model affords all digital attributes (ease of
transformation, distribution, and 3D printing) while the wax artifact can be
discarded or kept as a one-of-a-kind memento. We present a proof-of-concept
implementation of D-Coil and showcase how this additive approach can also be
extended to a subtractive process using a digitally actuated cutter. By adding
a 6DOF mouse, users can also include scaling, rotation, and bending effects to
create a wide variety of shapes often difficult for novices to produce in
standard CAD software.

Summary: TRANSFORM is an exploration of how shape display technology can be
integrated into our everyday lives as interactive, shape changing furniture.
These interfaces not only serve as traditional computing devices, but also
support a variety of physical activities. By creating shapes on demand or by
moving objects around, TRANSFORM changes the ergonomics, functionality and
aesthetic dimensions of furniture. The video depicts a story with various
scenarios of how TRANSFORM shape shifts to support a variety of use cases in
the home and in the work environment: It holds and moves objects like fruits,
game tokens, office supplies and tablets; creates dividers on demand; and
generates interactive sculptures to convey messages and audio.

Summary: This video presents a novel technique for embedding optic fibers into a
metal blade to sense objects that the knife is cutting. In particular, we
present a design for a kitchen knife with fiber optics between the edge of the
blade and the handle, with a skin-color sensor that overcomes the complex
conditions in the kitchen. Hoping this design will lead to future work on
minimizing cooking injuries, our handheld device also includes a simple
finger-protection mechanism in the form of a retracting blade. We present our
novel hardware design, an initial study of imaging capabilities, and a
discussion of future directions.

Summary: We present an approach to combining digital fabrication and craft,
demonstrating a hybrid interaction paradigm where human and machine work in
synergy. The FreeD is a hand-held digital milling device, monitored by a
computer while preserving the makers freedom to manipulate the work in many
creative ways. Relying on a pre-designed 3D model, the computer gets into
action only when the milling bit risks the objects integrity, preventing damage
by slowing down the spindle speed, while the rest of the time it allows
complete gestural freedom. We present the technology and explore several
interaction methodologies for carving. In addition, we present a user study
that reveals how synergetic cooperation between human and machine preserves the
expressiveness of manual practice. This quality of the hybrid territory evolves
into design personalization. We conclude on the creative potential of
open-ended procedures within this hybrid interactive territory of manual smart
tools and devices.

Summary: In this demo paper, we present the realization of a completely aesthetically
driven conductive image as a multi-modal music controller. Combining two
emerging technologies -- rapid prototyping with an off-the-shelf inkjet printer
using conductive ink and parametric graphic design, we are able to create an
interactive surface that is thin, flat, and flexible. This sensate surface can
be conformally wrapped around a simple curved surface, and unlike touch
screens, can accommodate complex structures and shapes such as holes on a
surface. We present the design and manufacturing flow and discuss the
technology behind this multi-modal sensing design. Our work seeks to offer a
new dimension of designing sonic interaction with graphic tools, playing and
learning music from a visual perspective and performing with expressive
physical manipulation.

Summary: 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 tool paths, 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.

Summary: 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.

Summary: We present an approach to combine digital fabrication and craft that is
focused on a new fabrication experience. The FreeD is a hand-held, digitally
controlled, milling device. It is guided and monitored by a computer while
still preserving gestural freedom. The computer intervenes only when the
milling bit approaches the 3D model, which was designed beforehand, either by
slowing down the spindle's speed or by drawing back the shaft. The rest of the
time it allows complete freedom, allowing the user to manipulate and shape the
work in any creative way. We believe The FreeD will enable a designer to move
in between the straight boundaries of established CAD systems and the free
expression of handcraft.

Summary: In this video we present a special guitar that combines physical acoustic
properties with virtual capabilities. A wooden resonator -- a unique,
replaceable piece of wood that gives the guitar a unique acoustic sound, will
embody the acoustical values. The acoustic signal created by this wooden heart
will be digitally processed in a virtual sound box in order to create flexible
sound design. The project shows that traditional values can be embedded into a
digital object.
