Summary: There are three key factors that can reduce the productivity of
brainstorming. In this study, we focus on evaluation apprehension, whereby the
fear of negative evaluations from other members prevents subjects from
generating and presenting their ideas. To mitigate evaluation apprehension
problem, we propose a novel approach that reduces the effort required to give
positive feedback. We introduce a physical analogue to Facebook's "Like"
button, enabling people to give positive feedback expressly and casually with a
physical button in face-to-face brainstorming. We examined how this system can
be used "in the wild."

Summary: This paper proposes a new shadow interface system that provides tactile
feedback from a user's shadow to physical body. When users obstruct the
projected image by their bodies, wearable photoreactive tactile displays
receive the light information; they decode it and transmit tactile sensation.
The proposed system does not require complex sensing, complicated settings and
communication systems; it can perform high speed tactile feedback with the
information directly received from the projected light. Perspective projection
of the projected image and occluding objects that generate shadows is preserved
in principle; all the users have to do is obstructing the projected light. In
this paper, we present the concept, the first prototype of the system, and
basic evaluations. The system can easily serve as a human interaction system
with touch sensitive shadow, and it has potential applications in the areas of
interactive entertainment and user interfaces.

Summary: We propose a novel display method, EnchanTable, that can augment a table
surface with mid-air images. Users can interact with visual images displayed on
the table by using real objects. In our optical design, we place an optical
imaging device behind a table so that the light from the device forms a
vertically standing mid-air image reflected at the table surface. This design
displays the image right on the table. The merit of our method is that the only
requirement is for the table to have a reflective surface. Utilizing this, we
can place any devices, such as touch sensors, around the table, or display
mid-air images on a tablet whose surface is sufficiently reflective. Owing to
its compactness, this method can be applied to other tabletop-interaction
systems.

Summary: Tabletop displays have been used to share information among multiple users.
However, there are two problems with current tabletop displays: The display
area is limited to horizontal surfaces, and there is a lack of view-dependent
appearance regarding displayed images. The aim of this paper is to overcome
these limitations by adding dual-sided vertical mid-air images to a horizontal
surface for a richer and more impressive visual presentation. For this purpose,
we introduce a plate-shaped mid-air imaging optics as a tabletop surface and a
diffusion control film for the projection of horizontal images. The proposed
system, "HoVerTable," can display a combination of horizontal and vertical
images for users facing each other. We have developed interactive applications
on HoVerTable, including a card battle game and an application for the
augmentation of physical objects.

Summary: When taking a photo, such verbal prompts as "cheese" or "smile" are often
used by photographers to get natural smiles from their subjects. However, since
the obtained smiles usually look forced or resemble a grimace, capturing a
natural smile is difficult. We propose an active camera system called
"Laughin'Cam" that obtains natural-looking portraits by eliciting spontaneous
smiles by presenting the sound of laughter. The proposed system utilizes an
emotional contagion effect, which is the tendency of emotional behavior to
spread from person to person. We conducted an evaluation experiment with our
proposed system using computer vision and also performed a subjective
experiment. Our results suggested that our system could efficiently induce
naturally-looking and spontaneous smiles.

Summary: We propose design methods that process the surface of Urushi, a Japanese
traditional coating material, with computer technology and ultraviolet (UV)
light control. Urushi changes their physical condition by absorbing UV light
energy. Our research introduces design method with this physical feature for
Personal Fabrication by utilizing UV laser and galvanometer mirror or UV lamp
and paper.
Our contribution is to introduce the principle of the new fabrication
method. This method is able to add a pattern onto the Urushi coated surface by
controlling the UV light direction. We use two methods to control of the light.
One method uses laser and galvanomirror. Another one uses a lamp and mask
pattern. We introduce and compare these methods, and describe future of Urushi
design.

Summary: We propose an effective combination of multiple functional inks, including
conductive silver ink, thermo-chromic ink, and regular inkjet ink, for a novel
paper-based interface called Inkantatory Paper that can dynamically change the
color of its printed pattern. Constructed with off-the-shelf inkjet printing
using silver conductive ink, our system enables users to fabricate thin, flat,
flexible, and low-cost interactive paper. We evaluated the characteristics of
the conductive silver ink as a heating system for the thermo-chromic ink and
created applications demonstrating the usability of the system.

Summary: This paper proposes a novel interactive system that supports augmented
reality interaction between mid-air images and physical objects. Our "Mid-air
Augmented Reality Interaction with Objects (MARIO)" system enables visual
images to be displayed at various positions and precise depths in mid-air. For
entertainment purposes, a game character appears in mid-air and runs around and
over "real" blocks which users have arranged by hands. Users thereby enjoy
interaction with physical blocks and virtual images.

Summary: Natural environments record their past and reveal usage in subtle cues such
as erosion and footprints. In modern society of concrete cities and dynamic
touch screens, this richness is lost.
We present a large size interactive floor display that captures visitors'
footsteps in playful prints to make a modern environment into a canvas of past
activities. The implementation consists of a carpet coated with color changing
ink and shoes that activate color changes. Each step a visitor makes results in
a dynamic print that slowly fades away.

Summary: We have developed a hybrid writing and erasure system called Hand-rewriting
in which both human users and computer systems can write and erase freely on
the same piece of paper. When the user writes on a piece of paper with a pen,
for example, the computer system can erase what is written on the paper, and
additional content can be written on the paper in natural print-like colors. We
achieved this hybrid writing and erasure on paper by localized heating combined
with handwriting with thermochromic ink and localized ultraviolet-light
exposure on paper coated with photochromic material. This paper describes our
research motivation, design, and implementation of this interface and examples
of applications.

Summary: In this paper, focusing on the writing sound when using an ordinary paper
and pen, we explain how auditory feedback augments the act of writing.
Specifically, we evaluated the effectiveness of the auditory feedback by
comparing writing tasks, which involved tracing Chinese characters, Without
Feedback (No), with Monaural Feedback (MF), and Stereo Feedback (SF). The
results of this study showed that auditory feedback (MF and SF) of writing
produced more written characters than Without Feedback (No) and had fewer
negative impressions during the writing task.

Summary: A more flexible and impressive depiction results with traditional hand-drawn
animation than with computer graphics. We propose a technique for anime-like
exaggeration of perspective. Our technique is used to achieve a dynamic
depiction when rendering animation using multi-perspective rendering.
Multi-perspective rendering is a non-photorealistic rendering method that
combines what is seen from several viewpoints into a single image and enables
the rendering of anomalous pictures. We focused on a systematic arrangement of
viewpoints specialized to depict an exaggerated rendering of a figure model
with articulated joints so that these viewpoints represent exaggerations
similar to traditional freehand drawing in anime. For this purpose, we
constructed a tree structure we call "viewpoint hierarchy" (VH), which is
isomorphic to joint hierarchy, with nodes containing the viewpoints necessary
for multiple perspectives. Our technique dynamically arranges each viewpoint
between the viewpoint's parent node and a control point embedded in a figure
model. Our real-time implementation and experimentation show that
perspective-combined images are preferable for dynamic movement and immersion.

Summary: SolaColor is a scheme for creating a place (namely, a floor space) whose
color is varied in response to sunlight. The aim of this work is to create
sustainable spatial rendition by utilizing sunlight. A feature of this
spatial-rendition scheme is rendering places by color -- rather than contrast
-- of lighting. By means of SolaColor, areas in sunlight are colored in pink,
while shaded areas are colored white. When this scheme is practically applied,
time-varying patterns appear in synchronization with the movement of the sun.
When a person or object enters a space created by SolaColor, white shadows
oriented according to the position of the sun are formed in the manner of a
sundial. The scheme can be implemented by utilizing photochromic material and
optical design, and it can be introduced in any location under sunlight without
the need for an electrical-power supply.

Summary: The goal of our research is to support cooperative work performed by
stakeholders sitting around a table. To support such cooperation, various
table-based systems with a shared electronic display on the tabletop have been
developed. These systems, however, suffer the common problem of not recognizing
shared information such as text and images equally because the orientation of
their view angle is not favorable. To solve this problem, we propose the
Lumisight Table. This is a system capable of displaying personalized
information to each required direction on one horizontal screen simultaneously
by multiplexing them and of capturing stakeholders' gestures to manipulate the
information.

Summary: It is obvious that faster processors are essential for virtual reality
applications. Recently, we have a new generation of graphics hardware which can
enhance the reality of interactive graphics. Although it is designed for
rendering purpose, its programmability is expected to be effective for other
general applications. This paper evaluates its performance as an image
processing unit especially for image filtering and stereo matching. First, we
focus on image filtering, and compare GPU (ATI RADEON 9700 Pro) implementations
to optimized CPU (Intel Pentium 4 3.06GHz) ones. Experimental results show
that, for linear filtering, GPUs are from three to six times faster than CPUs.
Then, we implement a block-based stereo matching algorithm using filters and
depth-test-based optimization on the GPU. This implementation is shown to be
twice faster than a CPU implementation. Finally, a system based on this
algorithm is constructed to estimate depth from two video sequences in real
time.
