Summary: While 3D printing offers great design flexibility before the object is
printed, it is very hard for end-users to customize a 3D-printed object to
their specific needs after it is printed. We propose HotFlex: a new approach
allowing precisely located parts of a 3D object to transition on demand from a
solid into a deformable state and back. This approach enables intuitive
hands-on remodeling, personalization, and customization of a 3D object after it
is printed. We introduce the approach and present an implementation based on
computer-controlled printed heating elements that are embedded within the 3D
object. We present a set of functional patterns that act as building blocks and
enable various forms of hands-on customization. Furthermore, we demonstrate how
to integrate sensing of user input and visual output. A series of technical
experiments and various application examples demonstrate the practical
feasibility of the approach.

Summary: Foldios are foldable interactive objects with embedded input sensing and
output capabilities. Foldios combine the advantages of folding for thin,
lightweight and shape-changing objects with the strengths of thin-film printed
electronics for embedded sensing and output. To enable designers and end-users
to create highly custom interactive foldable objects, we contribute a new
design and fabrication approach. It makes it possible to design the foldable
object in a standard 3D environment and to easily add interactive high-level
controls, eliminating the need to manually design a fold pattern and low-level
circuits for printed electronics. Second, we contribute a set of printable user
interface controls for touch input and display output on folded objects.
Moreover, we contribute controls for sensing and actuation of shape-changeable
objects. We demonstrate the versatility of the approach with a variety of
interactive objects that have been fabricated with this framework.

Summary: 3D printing is widely used to physically prototype the look and feel of 3D
objects. Interaction possibilities of these prototypes, however, are often
limited to mechanical parts or post-assembled electronics. In this paper, we
present Capricate, a fabrication pipeline that enables users to easily design
and 3D print highly customized objects that feature embedded capacitive
multi-touch sensing. The object is printed in a single pass using a commodity
multi-material 3D printer. To enable touch input on a wide variety of 3D
printable surfaces, we contribute two techniques for designing and printing
embedded sensors of custom shape. The fabrication pipeline is technically
validated by a series of experiments and practically validated by a set of
example applications. They demonstrate the wide applicability of Capricate for
interactive objects.

Summary: Although different types of touch surfaces have gained extensive attention
in HCI, this is the first work to directly compare them for two critical
factors: performance and ergonomics. Our data come from a pointing task (N=40)
carried out on five common touch surface types: public display (large,
vertical, standing), tabletop (large, horizontal, seated), laptop (medium,
adjustably tilted, seated), tablet (seated, in hand), and smartphone (single-
and two-handed input). Ergonomics indices were calculated from biomechanical
simulations of motion capture data combined with recordings of external forces.
We provide an extensive dataset for researchers and report the first analyses
of similarities and differences that are attributable to the different postures
and movement ranges.

Summary: We propose iSkin, a novel class of skin-worn sensors for touch input on the
body. iSkin is a very thin sensor overlay, made of biocompatible materials, and
is flexible and stretchable. It can be produced in different shapes and sizes
to suit various locations of the body such as the finger, forearm, or ear.
Integrating capacitive and resistive touch sensing, the sensor is capable of
detecting touch input with two levels of pressure, even when stretched by 30%
or when bent with a radius of 0.5cm. Furthermore, iSkin supports single or
multiple touch areas of custom shape and arrangement, as well as more complex
widgets, such as sliders and click wheels. Recognizing the social importance of
skin, we show visual design patterns to customize functional touch sensors and
allow for a visually aesthetic appearance. Taken together, these contributions
enable new types of on-body devices. This includes finger-worn devices,
extensions to conventional wearable devices, and touch input stickers, all
fostering direct, quick, and discreet input for mobile computing.

Summary: PrintScreen is an enabling technology for digital fabrication of customized
flexible displays using thin-film electroluminescence (TFEL). It enables
inexpensive and rapid fabrication of highly customized displays in low volume,
in a simple lab environment, print shop or even at home. We show how to print
ultra-thin (120 µm) segmented and passive matrix displays in greyscale or
multi-color on a variety of deformable and rigid substrate materials, including
PET film, office paper, leather, metal, stone, and wood. The displays can have
custom, unconventional 2D shapes and can be bent, rolled and folded to create
3D shapes. We contribute a systematic overview of graphical display primitives
for customized displays and show how to integrate them with static print and
printed electronics. Furthermore, we contribute a sensing framework, which
leverages the display itself for touch sensing. To demonstrate the wide
applicability of PrintScreen, we present application examples from ubiquitous,
mobile and wearable computing.

Summary: This paper contributes results from an empirical study of on-skin input, an
emerging technique for controlling mobile devices. Skin is fundamentally
different from off-body touch surfaces, opening up a new and largely unexplored
interaction space. We investigate characteristics of the various skin-specific
input modalities, analyze what kinds of gestures are performed on skin, and
study what are preferred input locations. Our main findings show that (1) users
intuitively leverage the properties of skin for a wide range of more expressive
commands than on conventional touch surfaces; (2) established multi-touch
gestures can be transferred to on-skin input; (3) physically uncomfortable
modalities are deliberately used for irreversible commands and expressing
negative emotions; and (4) the forearm and the hand are the most preferred
locations on the upper limb for on-skin input. We detail on users' mental
models and contribute a first consolidated set of on-skin gestures. Our
findings provide guidance for developers of future sensors as well as for
designers of future applications of on-skin input.

Summary: We present a multimodal on-surface and near-surface sensing technique for
planar, curved and flexible surfaces. Our technique leverages temporal
multiplexing of signals coming from a universal interdigitated electrode
design, which is printed as a single conductive layer on a flexible substrate.
It supports sensing of touch and proximity input, and moreover is capable of
capturing several levels of pressure and flexing. We leverage recent
developments in conductive inkjet printing as a way to prototype electrode
patterns, and combine this with our hardware module for supporting the full
range of sensing methods. As the technique is low-cost and easy to implement,
it is particularly well-suited for prototyping touch- and hover-based user
interfaces, including curved and deformable ones.

Summary: We contribute Permulin, an integrated set of interaction and visualization
techniques for multi-view tabletops to support co-located collaboration across
a wide variety of collaborative coupling styles. These techniques (1) provide
support both for group work and for individual work, as well as for the
transitions in-between, (2) contribute sharing and peeking techniques to
support mutual awareness and group coordination during phases of individual
work, (3) reduce interference during group work on a group view, and (4)
directly integrate with conventional multi-touch input. We illustrate our
techniques in a proof-of-concept implementation with the two example
applications of map navigation and photo collages. Results from two user
studies demonstrate that Permulin supports fluent transitions between
individual and group work and exhibits unique awareness properties that allow
participants to be highly aware of each other during tightly coupled
collaboration, while being able to unobtrusively perform individual work during
loosely coupled collaboration.

Summary: This works introduces layer jamming as an enabling technology for designing
deformable, stiffness-tunable, thin sheet interfaces. Interfaces that exhibit
tunable stiffness properties can yield dynamic haptic feedback and shape
deformation capabilities. In comparison to the particle jamming, layer jamming
allows for constructing thin and lightweight form factors of an interface. We
propose five layer structure designs and an approach which composites multiple
materials to control the deformability of the interfaces. We also present
methods to embed different types of sensing and pneumatic actuation layers on
the layer-jamming unit. Through three application prototypes we demonstrate the
benefits of using layer jamming in interface design. Finally, we provide a
survey of materials that have proven successful for layer jamming.

Summary: We propose cutting as a novel paradigm for ad-hoc customization of printed
electronic components. As a first instantiation, we contribute a printed
capacitive multi-touch sensor, which can be cut by the end-user to modify its
size and shape. This very direct manipulation allows the end-user to easily
make real-world objects and surfaces touch-interactive, to augment physical
prototypes and to enhance paper craft. We contribute a set of technical
principles for the design of printable circuitry that makes the sensor more
robust against cuts, damages and removed areas. This includes novel physical
topologies and printed forward error correction. A technical evaluation
compares different topologies and shows that the sensor remains functional when
cut to a different shape.

Summary: In this paper, we address the challenges of occlusion created by physical
objects on interactive tabletops. We contribute an integrated set of
interaction techniques designed to cope with the physical occlusion problem as
well as facilitate organizing objects in hybrid settings. These techniques are
implemented in ObjecTop, a system to support tabletop display applications
involving both physical and virtual objects. We compile design requirements for
occlusion-aware tabletop systems and conduct the first in-depth user study
comparing ObjecTop with conventional tabletop interfaces in search and layout
tasks. The empirical results show that occlusion-aware techniques outperform
the conventional tabletop interface. Furthermore, our findings indicate that
physical properties of occluders dramatically influence which strategy users
employ to cope with occlusion. We conclude with a set of design implications
derived from the study.

Summary: Interactive tables are well suited for co-located collaboration. Most prior
research assumed users to share the same overall display output; a key
challenge was the appropriate partitioning of screen real estate, assembling
the right information 'at the users' finger-tips through simultaneous input. A
different approach is followed in recent multi-view display environments: they
offer personal output for each team member, yet risk to dissolve the team due
to the lack of a common visual focus. Our approach combines both lines of
thought, guided by the question: "What if the visible output and simultaneous
input was partly shared and partly private?" We present Permulin as a concrete
corresponding implementation, based on a set of novel interaction concepts that
support fluid transitions between individual and group activities, coordination
of group activities, and concurrent, distraction-free in-place manipulation.
Study results indicate that users are able to focus on individual work on the
whole surface without notable mutual interference, while at the same time
establishing a strong sense of collaboration.

Summary: There are many visions that touch on the future of human computer
interaction from a trans-human future to a post-technological UI. However
visions related to the progress of technology are not new. Creative and
insightful visionaries from Denis Diderot to Vannevar Bush have been
postulating visions of possible futures or technology for centuries. Some
idealised views end up discredited with advances in knowledge, while others now
appear remarkably prescient. The question is, do visions and the process of
creating them have a place in CHI, or are they simply flights of fancy?
This SIG meeting provides a forum for visionaries; researchers and
practitioners looking to consider the place and importance of visions within
CHI. Can visions, the process of visioning and forming new visions help us
refine, advance or develop new research or forms of interaction. And if visions
are important to us, then are they part of the regular academic process? If so,
should CHI provide venues for publishing new visions?

Summary: This video demonstrates Flexpad, a highly flexible display interface.
Flexpad introduces a novel way of interacting with flexible displays by using
detailed deformations. Using a Kinect camera and a projector, Flexpad
transforms virtually any sheet of paper or foam into a flexible, highly
deformable and spatially aware handheld display. It uses a novel approach for
tracking deformed surfaces from depth images very robustly, in high detail and
in real time. As a result, the display is considerably more deformable than
previous work on flexible handheld displays, enabling novel applications that
leverage the high expressiveness of detailed deformation. We illustrate these
unique capabilities through three application examples: curved cross-cuts in
volumetric images, deforming virtual paper characters, and slicing through time
in videos.

Summary: MetaSolid is an imaginary material that changes its state between soft and
solid on demand. It allows us to explore the potential of future flexible
interfaces that programmatically control their material characteristics. When
is flexibility for an interface needed and when is rigidness better? This video
sketch proposes novel interactive and collaborative experiences around the idea
of MetaSolid to stimulate future research and development on novel materials
and interaction techniques. Besides classical gestures like folding or bending
the interface, new ways appear, such as crumbling, stretching or tickling.
These enable the user to easily form, display and modify virtual
representations of real physical objects.

more expressive interaction with information. The goal of the workshop is to
push the current discussion forward towards a synthesis of emerging
visualization and interaction concepts in the area of improvised, minimal,
curved and malleable interactive surfaces. By doing so, we aim to generate an
agenda for future research and development in interactive surfaces.

Summary: Flexpad is an interactive system that combines a depth camera and a
projector to transform sheets of plain paper or foam into flexible, highly
deformable, and spatially aware handheld displays. We present a novel approach
for tracking deformed surfaces from depth images in real time. It captures
deformations in high detail, is very robust to occlusions created by the user's
hands and fingers, and does not require any kind of markers or visible texture.
As a result, the display is considerably more deformable than in previous work
on flexible handheld displays, enabling novel applications that leverage the
high expressiveness of detailed deformation. We illustrate these unique
capabilities through three application examples: curved cross-cuts in
volumetric images, deforming virtual paper characters, and slicing through time
in videos. Results from two user studies show that our system is capable of
detecting complex deformations and that users are able to perform them quickly
and precisely.

Summary: Recent technical advances allow traditional wristwatches to be equipped with
high processing power. Not only do they allow for glancing at the time, but
they also allow users to interact with digital information. However, the
display space is very limited. Extending the screen to cover the entire forearm
is promising. It allows the display to be worn similarly to a wristwatch while
providing a large display surface. In this paper we present the design space of
a display-augmented forearm, focusing on two specific properties of the
forearm: its hybrid nature as a private and a public display surface and the
way clothing influences information display. We show a wearable prototypical
implementation along with interactions that instantiate the design space:
sleeve-store, sleeve-zoom, public forearm display and interactive tattoo.

Summary: Pico projectors have lately been investigated as mobile display and
interaction devices. We propose to use them as 'light beams': Everyday objects
sojourning in a beam are turned into dedicated projection surfaces and tangible
interaction devices. This way, our daily surroundings get populated with
interactive objects, each one temporarily chartered with a dedicated sub-issue
of pervasive interaction. While interaction with objects has been studied in
larger, immersive projection spaces, the affordances of pico projections are
fundamentally different: they have a very small, strictly limited field of
projection, and they are mobile. This paper contributes the results of an
exploratory field study on how people interact with everyday objects in pico
projections in nomadic settings. Based upon these results, we present novel
interaction techniques that leverage the limited field of projection and
trade-off between digitally augmented and traditional uses of everyday objects.

illustrate our thoughts by means of a first prototype. Early evaluation results
indicate that it effectively supports mobile social encounters.

Summary: Pico projectors have lately been investigated as mobile display and

sojourning in a beam are turned into dedicated projection surfaces and tangible
interaction devices. While this has been explored for large projectors, the
affordances of pico projectors are fundamentally different: they have a very
small and strictly limited projection ray and can be carried around in a
nomadic way during the day. Thus it is unclear how this could be actually
leveraged for tangible interaction with physical, real world objects. We have
investigated this in an exploratory field study and contribute the results.
Based upon these, we present exemplary interaction techniques and early user
feedback.

Summary: This paper addresses challenges created by physical objects that occlude
screen contents on interactive tabletops. We propose novel techniques to
support awareness, access and overview of occluded digital objects. These
techniques take into account different functional zones on tabletops to provide
information at varying levels of detail. We also contribute the PressView
technique, a pressure-based interaction technique to get a quick overview of
occluded objects.
