        Direct Share: Photo Management System Based on Round-robin Concept-driven User Preference Feedback

        ( Tae Houn Song ),( Soon Mook Jeong ),( Hyung Min Kim ),( Key Ho Kwon ),( Jae Wook Jeon ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.7

        As the size of camera modules is decreasing and as the computing performance of portable devices is improving, taking photos has become a part of daily life. However, existing photo management programs and products that manage such photos still require extensive user effort to facilitate the sharing and browsing of images. It is especially difficult for novice users to manage and share photos. In this paper, we develop a round-robin concept-driven user preference feedback mechanism for achieving direct photo sharing, instant display, and easy management using optimized user controls and user preference-driven classification. Compared with commercial photo management systems, our proposed solution provides new features: optimized user controls, direct sharing and instant display, and user preference feedback driven classification. These new features boost the round-robin concept-driven user preference feedback. This paper proposes a photo finder that automatically searches for photos in storage spaces or cameras. The proposed photo finder relies on user preference feedback to share photos by leveraging user preferences, and the round-robin connection transmits photos to the family``s digital photo frame or web album by arbiter. The proposed method saves time and spares users the effort required for photo management. Moreover, this method does not merely direct photo sharing and simple photo management, but it also increases the satisfaction level of users viewing the photos.

      • 현실감 있는 윷놀이 게임

        송태훈(Tae Houn Song),정순묵(Soon Mook Jeong),권기호(Key Ho Kwon),전재욱(Jae Wook Jeon) 한국HCI학회 2010 한국HCI학회 학술대회 Vol.2010 No.1

        본 논문은 현실감 있는 윷놀이 게임을 만드는데 그 목적이 있다. 현실감 있는 윷놀이란, 사용자가 실제 윷을 던지는 행위를 입력으로 사용하고, 음성으로 말을 조종함으로써 컴퓨터와 사람간에 자연스러운 인터페이스를 구현하는데 그 목적이 있다. 또한 애니메이션 제작에 사용되는 플래시를 이용하여 사용자 인터페이스를 구성함으로써 사용자가 보다 쉽고 재미있게 게임에 몰입할 수 있도록 한다. 본 논문을 구현하기 위해 적외선센서와 가속도센서, 지그비 모듈, 그리고 이들 센서를 제어하는데 사용할 마이크로 프로세서를 이용하여 게임에 사용되는 윷을 만든다. 적외선센서는 윷의 앞/뒷면 상태를 측정하는데 사용되고, 가속도 센서는 윷의 3 차원상에서의 위치를 파악하는데 사용된다. 윷의 위치와 앞/뒷면 상태는 지그비 모듈을 이용하여 컴퓨터에 전달되고, 사용자의 음성 명령으로 자신의 말을 움직일 수 있다. 본 논문의 의의는, 현재 널리 사용되는 센서, 통신, 시각화 기술과 음성인식 기능을 결합하여 보다 현실감 있고 자연스러운 사용자 인터페이스를 만드는데 있다. This paper proposes make sense for the real interaction in playing Yut games. In order to make the practical interface, uses the user input with user throws a Yuts and make a move on the game board using voice commands. And build a user interface use the Flash program. For this research implementation make a digital Yut-makes Yut with Infrared, accelerator sensor, ZigBee module and uses the processor-and using voice recognition software. Digital Yuts connect to host PC with ZigBee communication. This research focus on make natural user interaction between human-computer with combine widely used sensor, animation program, and communication protocol.

      • Design the Video Conferencing Robot for One-to-Many Communication using Smartphone

        Dong-Won Choi,Tae-Houn Song,Soon-Mook Jeong,Jae Wook Jeon 제어로봇시스템학회 2011 제어로봇시스템학회 국제학술대회 논문집 Vol.2011 No.10

        Robots have been used in various fields. In particular, interest in robots in business applications is increasing. This paper shows the design and development of a remote video conferencing robot so as to use this robot safely and conveniently by integrating separately conducted studies. We can connect to this robot at anytime anywhere using smart phone via WCDMA(Wideband CDMA) or WiFi(Wireless Fidelity). This has the advantages of mobility and conveniece. It can perform one-to-many communications by connecting smart phone to robot. Therefore, users can improve their efficiency.

      • OpenMP Parallel Programming Using Dual-Core Embedded System

        Kyung Min Lee,Tae Houn Song,Seung Hyun Yoon,Key Ho Kwon,Jae Wook Jeon 제어로봇시스템학회 2011 제어로봇시스템학회 국제학술대회 논문집 Vol.2011 No.10

        Multi-cores have recently been applied to smartphones, as well as PCs; the performance of electronic devices is improving. However, there is no improvement in performance, if the existing sequential program is executed on multi-core processors. Parallel programming is necessary to use multi-core processors well. Already some companies are doing projects to parallel their own programs that are executed in the PC environment, for example, Adobe Systems Inc., Autodesk Inc., and Epic Games Inc. However, very few embedded field studies, focus on parallel programming. In this paper, we study a parallel programming model, OpenMP, and parallel programs that can be benchmarked to multi-core processors of embedded boards using OpenMP. We execute parallel programs on a dual-core embedded system. We analyze the performance of sequential programs and parallel programs by SERPOP analysis. Finally, we reduce the execution time of programs by a mean of 111%.
