14. imMatch: Fast Stitching Gestures for Multiple Heterogeneous
Multi-touch Surfaces.
Paper in Submission.
My Role in this project – Co-Concept, Co-Author, Programing Support,
Design & Video
In this research, we proposed several gestures, tried to find a better way to operate
the attachment of multiple multitouch displays. Also, we developed a HTML5 soft-
ware development kit (SDK) which would make it easier to explore the possibility of
multiple multitouch display applications.
Detail
Four gestures were designed and evaluated; Swipe, Pinch, Slide and Circle gestures.
Gestures could be used to estimate dot per inch (DPI) of the stitched devices which
DPI information is not able to obtain. When devices were stitched, their margins
would not able to detect touch events. Seamless gestures were developed to make the
cross-devices multi-touch gesture working like one original multi-touch surface. Sev-
eral applications were developed and introduced to demonstrate the private / public
mode switching by using stitching gesture.

The proposed techniques enable a collaborative multi-display multi-touch tabletop
system. We also present three interactive tools: i-m-View, i-m-Lamp, and i-m-Flash-
light, which consist of a mobile tablet and projectors that users can freely interact
with beyond the main display surface.

16. Current tabletop systems are designed to sense 2D interactions taken place on the
tabletop surface, such as finger touches and tangible objects. The ability to interact
above the tabletop surface makes it possible to support 3D interactions. For example,
an architect can examine a 2D blueprint of a building shown on the tabletop display
while inspecting 3D views of the building by moving a mobile display above the
tabletop. Recent approaches to localize objects in 3D requires visible markers or the
use of embedded sensors [Song et al. 2009]. The use of visible markers often interferes
with the content users are focusing on, limiting its usefulness and applicability.

This paper presents i-m-Space, an interactive multimedia rehabilitation space that helps the post-surgery
recovery of breast cancer patients. Our goal is to improve patients' physical therapy and psychological
relaxation experience through careful applications of multimedia technology. i-m-Space consists of three
Page5

Our inter-disciplinary team includes medical professionals, multimedia engineers, designers, and artists. We
have implemented i-m-Space in an experimental space in collaboration a local breast cancer foundation. To
evaluation i-m-Space, we have recruited several patients who recently recovered from breast cancer to use
i-m-Space and to share their first-hand experiences. Our contributions includes the following: 1) injecting a
sense of fun and playfulness into traditional therapy to attract patients; 2) providing therapists with sufficient
flexibility so they can personalize therapy sessions for each patient; 3) maintaining safety of patients.

In this paper we introduce a tubular interface, the i-m-Tube, which provides convenient user interaction with
multimedia content by multi-touch input and multi-resolution display. With its tubular surface, the i-m-Tube
is suitable for displaying panoramic image content like the Chinese scroll painting "Along the River During
the Ch'ingming Festival" which has been regarded as a national treasure and widely known by its
extraordinary width and its various details. The strength of our system is that it is not just suitable for
displaying panoramic content, but also possible to create an intuitive and natural context for user interaction
with multimedia content displayed on the i-m-Tube by multi-finger touch. It also provides a high resolution
area on demand, which is projected by a steerable projector in a Full-HD resolution. We have developed our
system as an interface which can be applied adaptively to different applications, having the features of
multi-touch and multi-resolution interactivity on a tubular display. In this work, we have implemented several
prototypes designed for different applications, like "Tetris360" aiming on co-op arcade gaming, and
"Panoramic Cover Flow" for interactive digital signage, to show the capabilities and opportunities of the
i-m-Tube display system. With our preliminary experiments on the i-m-Tube, it is exciting to see the potential
of the i-m-Tube as a new interface for people to meet the interactive multimedia touch in this generation.
Beyond the surface: 3D interactions for tabletop systems. In ACM SIGGRAPH 2010 Emerging

Current tabletop systems are designed to sense 2D interactions taken place on the tabletop surface, such as
finger touches and tangible objects. The ability to interact above the tabletop surface makes it possible to
support 3D interactions. For example, an architect can examine a 2D blueprint of a building shown on the
tabletop display while inspecting 3D views of the building by moving a mobile display above the tabletop.
Recent approaches to localize objects in 3D requires visible markers or the use of embedded sensors [Song et

Enabling Beyond Surface Interactions for Interactive Surface with An Invisible Projection.

This paper presents a programmable infrared (IR) technique that utilizes invisible, programmable markers to
support interaction beyond the surface of a diffused-illumination (DI) multi-touch system. We combine an IR
projector and a standard color projector to simultaneously project visible content and invisible markers.
Mobile devices outfitted with IR cameras can compute their 3D positions based on the markers perceived.
Markers are selectively turned off to support multi-touch and direct on-surface tangible input. The proposed
techniques enable a collaborative multi-display multi-touch tabletop system. We also present three interactive
tools: i-m-View, i-m-Lamp, and i-m-Flashlight, which consist of a mobile tablet and projectors that users can
freely interact with beyond the main display surface. Early user feedback shows that these interactive devices,
combined with a large interactive display, allow more intuitive navigation and are reportedly enjoyable to
use.
Public issues on projected user interface.
ACM CHI 2010, Extended Abstracts on Human Factors in Computing Systems April 2010
Authors: Ju Chun Ko
JU-CHUN KO, Li-Wei Chan, Yi-Ping Hung. (3 Citations)
What will happen when pocket projectors become mainstream personal display channels? What will be
affected when numerous projections intrude our living space without proper control? Today's technology in
projection has promised a big screen viewing experience from mobile devices, pushing us toward a truly
ubiquitous display environment. But, is our society prepared for the next projection-generation?
We argue that the Projected user interface (PUI) will introduce new problems both in environmental and
social aspects which are seldom been explored. This paper explores our rights to project and be projected in
public space. Can we project on human body without asking for permission? Can we refuse to be projected?
Can projection pollute the environment and influence the people therein? This paper proposes several issues
about people's rights on projection, and provide discussions on possible solutions.

This study of mobile persuasion system explores the use of a mobile phone, when attached to an everyday
object used by an everyday behavior, becomes a tool to sense and influence that behavior. This mobile
persuasion system, called Playful Bottle system, makes use of a mobile phone attached to an everyday
drinking mug and motivates office workers to drink healthy quantities of water. A camera and accelerometer
sensors in the phone are used to build a vision/motion-based water intake tracker to detect the amount and
regularity of water consumed by the user. Additionally, the phone includes hydration games in which natural
drinking actions are used as game input. Two hydration games are developed: a single-user TreeGame with
automated computer reminders and a multi-user ForestGame with computer-mediated social reminders from
members of the group playing the game. Results from 7-week user study with 16 test subjects suggest that
both hydration games are effective for encouraging adequate and regular water intake by users. Additionally,
results of this study suggest that adding social reminders to the hydration game is more effective than system
reminders alone.

Breathing is one of the most important functions in human body. Usually, people do not know enough about
how to breathe. Therefore, we develop a system which can detect the userpsilas breathing status and assist
him by multimedia. Our system allows a user to know their bodypsilas physical conditions and, through the
multimedia interactive feedback of the sense, the user can check weather their physical conditions are normal.
This physiological biofeedback system provides users an effective way to learn efficient breathing and
emotional control, and finally it helps to improve physical and mental health. In this way, it can help the users
to remain in relaxed condition most of the time. By combining smart clothing, interactive multimedia, and
expert knowledge of medical research and clinics, we build a smart clothing system which can amend the
userpsilas breathing habit, strengthen his immunity and improve his physical and mental health in a friendly
and natural way.

Nowadays, many people started to produce personal web pages, and most web pages contain multimedia
content. However, there are some problems with the design of web content, the web editor provided by web
pages is very inconvenient, and there also exists the inconsistent problem on web content when the content
had been accessed. To resolve these problems, we propose a multimedia on-line editing technique that
enables users to edit web content and add comments on-line. In addition, web content on different web sites
can be easily accessed by our system. The original web content that is accessed can be updated at the same

helps people who produce abundance and a large number of teaching materials, and it facilitates interaction
and communication among users.
QPalm: A gesture recognition system for remote control with list menu.

The coming ubiquity of digital media content is driving the need of a solution for improving the interaction
between the people and media. In this work, we proposed a novel interaction technique, QPalm, which allows
the user to control the media via a list menu shown on a distant display by drawing circles in the air with one
hand. To manipulate a list menu remotely, QPalm includes two basic functions, browse and choosing,
realized by recognizing the userpsilas palm performing circular and push motions in the air. The circular
motion provides fluidity in scrolling a menu up and down, while push motion is intuitive when the user
decided to choose an item during a circular motion. Based on this design, we develop a vision system based
on a stereo camera to track the userpsilas palm without interfering by intruders behind or next to the operating
user. For more specifically, the contribution of the work includes: (1) an intuitive interaction technique,
QPalm, for remote control with list menu, and (2) a palm tracking algorithm to support QPalm based on
merely depth and motion information of images for a practical consideration.

We have explored the design of a playful mug, called Mug-Tree, to motivate people to drink water regularly
and to develop a good water-drinking habit. Our system includes (1) a smart mug that can recognize user
drinking from it, and (2) a digital photo frame that displays a playful game connecting water drinking to
watering a virtual tree. The Mug-Tree reminds users to drink water regularly, and also help users to develop a
good water drinking habit by attracting continuous participation to this game.
