본 논문에서는 경량화 설계가 반영된 차량의 내구성 및 안전성을 증가시키기 위해 사용되는 구조용 접착제의 비균일적, 미도포 된 부분을 검사하기 위한 방법에 대해 제안한다. 이 방법은 차량이 조립되기 전 구조용 접착체가 균일하게 도포되지 않은 부분을 사전에 알려줌으로써 차량의 전체적인 강성을 높일 수 있어, 차량의 조립에 있어 의무화되어 가는 추세이다. 이 방법은 머신전용 카메라와 보드 기반으로 간단하게 구성이 가능하다.

We present a real-time interactive particle-art with human motion based on computer vision techniques. We used computer vision techniques to reduce the number of equipments that required for media art appreciations. We analyze pros and cons of various computer vision methods that can adapted to interactive digital media art. In our system, background subtraction is applied to search an audience. The audience image is changed into particles with grid cells. Optical flow is used to detect the motion of the audience and create particle effects. Also we define a virtual button for interaction. This paper introduces a series of computer vision modules to build the interactive digital media art contents which can be easily configurated with a camera sensor.

There are several researches on 2D gaze tracking techniques to the 2D screen for the Human-Computer Interaction. However, the researches for the gaze-based interaction to the stereo images or 3D contents are not reported. This paper presents a gaze-based 3D interaction technique on autostereoscopic display system.

Recently, the researches based on vision about user attention and action awareness are being pushed actively for human computer interaction. Among them, various applications of tabletop display system are developed more in accordance with touch sensing technique, co-located and collaborative work. Formerly, although supported only one user, support multi-user at present. Therefore, collaborative work and interaction of four elements (human, computer, displayed objects, physical objects) that is ultimate goal of tabletop display are realizable. Generally, tabletop display system designs according to four key aspects. 1)multi-touch interaction using bare hands. 2)implementation of collaborative work, simultaneous user interaction. 3)direct touch interaction. 4)use of physical objects as an interaction tool. In this paper, we describe a critical analysis of the state-of-the-art in advanced multi-touch sensing techniques for tabletop display system according to the four methods: vision based method, non-vision based method, top-down projection system and rear projection system. And we also discuss some problems and practical applications in the research field.

This paper proposes a robot motion authoring using finger-robot interaction. The proposed method is a user friendly method that easily authors (creates and controls) robot motion according to the number of fingers. The effectiveness of the proposed motion authoring method was verified based on motion authoring simulation of an industrial robot.

If a virtual object in a virtual environment represented by a stereo vision system could be touched by a user with some tactile feeling on his/her fingertip, the sense of reality would be heightened. To create a visual impression as if the user were directly pointing to a desired point on a virtual object with his/her own finger, we need to align virtual space coordinates and physical space coordinates. Also, if there is no tactile feeling when the user touches a virtual object, the virtual object would seem to be a ghost. Therefore, a haptic interface device is required to give some tactile sensation to the user. We have constructed such a human-computer interaction system in the form of a simple virtual reality game using a stereo vision system, a vibro-tactile device module, and two position/orientation sensors.

This paper proposes a novel human-computer interaction system for the disabled using recognition of face direction. Face direction is recognized by comparing positions of center of gravity between face region and facial features such as eyes and eyebrows. The face region is first selected by using color information, and then the facial features are extracted by applying a separation filter to the face region. The process speed for recognition of face direction is 6.57frame/sec with a success rate of 92.9% without any special hardware for image processing. We implement human-computer interaction system using screen menu, and show a validity of the proposed method from experimental results.

단백질-단백질 상호작용(PPI :Protein-Protein Interaction) 데이터는 생물체가 어떠한 메커니즘으로 생명을 유지하는지에 대한 정보를 담고 있다. 최근에는 생물학자들의 실험에 의해 많은 데이터가 축적되어 있으며, 데이터베이스로 구축되어 인터넷에 공개되어 있다. PPI 데이터는 단백질를 노드(node)로, 상호작용은 에지(edge)로 갖는 그래프(Graph) 구조로 표현 가능하다. 본 논문에서는 사용자가 PPI 데이터를 쉽게 가공하고 분석할 수 있도록 그래프 이론 기반에 기반하여 구현한 Proteinca(PROTEin INteraction CAbaret) 시스템에 대해 소개한다. Proteinca에 대한 자세한 정보는 http://jade.cs.pusan.ac.kr/${\sim}$proten에서 볼 수 있다.

Collision is a brief dynamic event consisting of the close approach of two or more objects or particles resulting in an abrupt change of momentum or exchange of energy because of interaction. Collisions play very important role in computer graphics, computer games and animations fields. Collisions can supply active interaction between cyberspace and real world and give much interests for making nice games so reasonable collision detection algorithms are needed. Collision detection algorithms should satisfy being fast and accuracy. In this paper, we survey the 2D collision detection algorithms between geometric models. We present several methods and system available for collision detection.
