Summary: Augmenting the physical world using projection technologies or head-worn
displays becomes increasingly popular in research and commercial applications.
However, a common problem is interference between the physical surface's
texture and the projection. In this paper, we present FreeTop, a combined
approach to finding areas suitable for projection, which considers multiple
aspects influencing projection quality, like visual texture and physical
surface structure. FreeTop can be used in stationary and mobile settings for
locating free areas in arbitrary physical settings suitable for projective
augmentation and touch interaction.

Summary: Smartwatches allow ubiquitous and mobile interaction with digital contents.
Because of the small screen sizes, traditional interaction techniques are often
not applicable. In this work, we show how the degree of freedom offered by the
elbow joint, i.e., flexion and extension, can be leveraged as an additional
one-handed input modality for smartwatches. By moving the watch towards or away
from the body, the user is able to provide input to the smartwatch without a
second hand. We present the results of a controlled experiment focusing on the
human capabilities for proximity-based interaction. Based on the results, we
propose guidelines for designing proximity-based smartwatch interfaces and
present ProxiWatch: a one-handed and proximity-based input modality for
smartwatches alongside a prototypical implementation.

Summary: Tilting and motion are widely used as interaction modalities in smart
objects such as wearables and smart phones (e.g., to detect posture or
shaking). They are often sensed with accelerometers. In this paper, we propose
to embed liquids into 3D printed objects while printing to sense various
tilting and motion interactions via capacitive sensing. This method reduces the
assembly effort after printing and is a low-cost and easy-to-apply way of
extending the input capabilities of 3D printed objects. We contribute two
liquid sensing patterns and a practical printing process using a standard
dual-extrusion 3D printer and commercially available materials. We validate the
method by a series of evaluations and provide a set of interactive example
applications.

Summary: The increasing number of smart objects in our everyday life shapes how we
interact beyond the desktop. In this workshop we discuss how advanced
interactions with smart objects in the context of the Internet-of-Things should
be designed from various perspectives, such as HCI and AI as well as industry
and academia.

Summary: User input in a virtual environment (VE) is usually accomplished through
simple finger interactions, such as walking in a 3D scene by pressing a button.
These interactions are not very suitable for movement in VE. Moving through
scenes such as a safety training applications by walking-in-place while
forgoing hand or finger input for other purposes enables a more realistic
feeling. Already existing solutions, such as multi-directional treadmills, are
still expensive and need additional fixation of the body. Others, like using
external tracking that are usually accomplished by using statically installed
cameras in CAVE-like-installations, also have limitations in terms of
occlusion. The built prototype -- an insole Directly measures the pressure
under the feet and hence enables a detection of movements, which is wirelessly
forwarded to the scene manager server.

Summary: ShoeSoleSense is a proof of concept, novel body worn interface -- an insole
that enables location independent hands-free interaction through the feet.
Forgoing hand or finger interaction is especially beneficial when the user is
engaged in real world tasks. In virtual environments as moving through safety
training applications is often conducted via finger input, which is not very
suitable. To enable a more intuitive interaction, alternative control concepts
utilize gesture control, which is usually tracked by statically installed
cameras in CAVE-like-installations. Since tracking coverage is limited,
problems may also occur. The introduced prototype provides a novel control
concept for virtual reality as well as real life applications. Demonstrated
functions include movement control in a virtual reality installation such as
moving straight, turning and jumping. Furthermore the prototype provides
additional feedback by heating up the feet and vibrating in dedicated areas on
the surface of the insole.

Summary: User input on television typically requires a mediator device such as a
handheld remote control. While being a well-established interaction paradigm, a
handheld device has serious drawbacks: it can be easily misplaced due to its
mobility and in case of a touch screen interface, it also requires additional
visual attention. Emerging interaction paradigms like 3D mid-air gestures using
novel depth sensors such as Microsoft's Kinect aim at overcoming these
limitations, but are known for instance to be tiring. In this paper, we propose
to leverage the palm as an interactive surface for TV remote control. Our
contribution is two-fold: (1) we have explored the conceptual design space in
an exploratory study. (2) Based upon these results, we investigated the
accuracy and effectiveness of such an interface in a controlled experiment. Our
results show that the palm has the potential to be leveraged for device-less
and eyes-free TV interactions without any third-party mediator device.
