imMatch: Fast Stitching Gestures for Multiple HeterogeneousMulti-touch Surfaces.Paper in Submission.My Role in this project – Co-Concept, Co-Author, Programing Support,Design & VideoIn this research, we proposed several gestures, tried to find a better way to operatethe attachment of multiple multitouch displays. Also, we developed a HTML5 soft-ware development kit (SDK) which would make it easier to explore the possibility ofmultiple multitouch display applications.DetailFour 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 whichDPI information is not able to obtain. When devices were stitched, their marginswould not able to detect touch events. Seamless gestures were developed to make thecross-devices multi-touch gesture working like one original multi-touch surface. Sev-eral applications were developed and introduced to demonstrate the private / publicmode switching by using stitching gesture.Demo Video

With its tubular surface, the i-m-Tubeis suitable for displaying panoramic image content like the Chinese scroll painting "Along the River Duringthe Chingming Festival" which has been regarded as a national treasure and widely known by itsextraordinary width and its various details. The strength of our system is that it is not just suitable fordisplaying panoramic content, but also possible to create an intuitive and natural context for user interactionwith multimedia content displayed on the i-m-Tube by multi-finger touch. It also provides a high resolutionarea on demand, which is projected by a steerable projector in a Full-HD resolution. We have developed oursystem as an interface which can be applied adaptively to different applications, having the features ofmulti-touch and multi-resolution interactivity on a tubular display. In this work, we have implemented severalprototypes 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 thei-m-Tube display system. With our preliminary experiments on the i-m-Tube, it is exciting to see the potentialof 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.

(9 Citations)This paper presents a programmable infrared (IR) technique that utilizes invisible, programmable markers tosupport interaction beyond the surface of a diffused-illumination (DI) multi-touch system. We combine an IRprojector 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 proposedtechniques enable a collaborative multi-display multi-touch tabletop system. We also present three interactivetools: i-m-View, i-m-Lamp, and i-m-Flashlight, which consist of a mobile tablet and projectors that users canfreely interact with beyond the main display surface.

Todays technology inprojection has promised a big screen viewing experience from mobile devices, pushing us toward a trulyubiquitous 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 andsocial aspects which are seldom been explored. This paper explores our rights to project and be projected inpublic 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?

Hsiao, JU-CHUN KO. (35 Citations)This study of mobile persuasion system explores the use of a mobile phone, when attached to an everydayobject used by an everyday behavior, becomes a tool to sense and influence that behavior. This mobilepersuasion system, called Playful Bottle system, makes use of a mobile phone attached to an everydaydrinking mug and motivates office workers to drink healthy quantities of water. A camera and accelerometersensors in the phone are used to build a vision/motion-based water intake tracker to detect the amount andregularity of water consumed by the user. Additionally, the phone includes hydration games in which naturaldrinking actions are used as game input. Two hydration games are developed: a single-user TreeGame withautomated computer reminders and a multi-user ForestGame with computer-mediated social reminders frommembers of the group playing the game. Results from 7-week user study with 16 test subjects suggest thatboth 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 systemreminders alone.Multimedia Feedback for Improving Breathing Habit.U-Media 2008: 1st IEEE International Conference on Ubi-media ComputingAuthors: Ju Chun KoMeng-Chieh Yu, Yi-Ping Hung, King-Jen Chang, Jin-Shing Chen, Su-Chu Hsu, JU-CHUN KO. (6 Citations)Breathing is one of the most important functions in human body. Usually, people do not know enough abouthow to breathe. Therefore, we develop a system which can detect the userpsilas breathing status and assisthim by multimedia. Our system allows a user to know their bodypsilas physical conditions and, through themultimedia 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 andemotional control, and finally it helps to improve physical and mental health. In this way, it can help the usersto remain in relaxed condition most of the time. By combining smart clothing, interactive multimedia, andexpert knowledge of medical research and clinics, we build a smart clothing system which can amend theuserpsilas breathing habit, strengthen his immunity and improve his physical and mental health in a friendlyand natural way.An Interactive Multimedia Web EditoreScience 08: IEEE Fourth International Conference on e-Science December 2008Authors: Ju Chun KoChung Li Fei-Pi Chu, Hsiang-An Wang, JU-CHUN KONowadays, many people started to produce personal web pages, and most web pages contain multimediacontent. However, there are some problems with the design of web content, the web editor provided by webpages is very inconvenient, and there also exists the inconsistent problem on web content when the contenthad been accessed. To resolve these problems, we propose a multimedia on-line editing technique thatenables users to edit web content and add comments on-line. In addition, web content on different web sitescan be easily accessed by our system. The original web content that is accessed can be updated at the samePage8
time so that both versions are the same. The proposed system can also be used to e-learning. This functionhelps people who produce abundance and a large number of teaching materials, and it facilitates interactionand communication among users.QPalm: A gesture recognition system for remote control with list menu.U-Media 2008: IEEE International Conference on Ubi-media Computing July 2008Authors: Ju Chun KoYu-Hsin Chang, Li-Wei Chan, JU-CHUN KO. (4 Citations)The coming ubiquity of digital media content is driving the need of a solution for improving the interactionbetween the people and media. In this work, we proposed a novel interaction technique, QPalm, which allowsthe user to control the media via a list menu shown on a distant display by drawing circles in the air with onehand. 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 circularmotion provides fluidity in scrolling a menu up and down, while push motion is intuitive when the userdecided to choose an item during a circular motion. Based on this design, we develop a vision system basedon a stereo camera to track the userpsilas palm without interfering by intruders behind or next to the operatinguser. 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 onmerely depth and motion information of images for a practical consideration.Mug-Tree: A Playful Mug to Encourage Healthy Habit of Drinking Fluid RegularlyACM UbiComp 2007: ACM International Conference on Ubiquitous Computing September 2007Authors: Ju Chun KoJU-CHUN KO.
