We commonly use the computer interface a generalized form. However, the requirement of the user various and some users cannot apply the general circumstance. For these requirements, this research suggests the non-verbal communication. The suggestion is that Mewing with the mouth in human behavior applies to the interaction of the computer This was offered in three forms. First, drawing application: second, the arcade game: third, the interactive book. in condusion, we confirmed that the suggestion of this research could be effectively used for the development of the human computer interface.

Recently technological drive on autonomous vehicle is on the rush. Along with the trend, researches on driver's perspective are increasing. However, previous studies have limitations in terms of study period and rich experience. In this paper, we conducted an ethnographically inspired fieldwork to observe human-autonomous car interaction. We had six participants to ride a prototype autonomous car on the real road for six days. After, we generated trust, distrust factors according to Lee & See's categorization of trust dimension: process, performance, and purpose. We derived eight distrust factors that saliently influences passenger's experience in autonomous vehicle. Our research broadens trust model into autonomous driving context based on real road field study and contributes to automotive community with design guidelines to increase trust toward autonomous vehicle.

Recently, there has been tremendous increase in human-computer/machine interaction system, where the goal is to provide with an appropriate service to the user at the right time with minimal human inputs for human augmented cognition system. To develop an efficient human augmented cognition system based on human computer/machine interaction, it is important to interpret the user's implicit intention, which is vague, in addition to the explicit intention. According to cognitive visual-motor theory, human eye movements and pupillary responses are rich sources of information about human intention and behavior. In this paper, we propose a novel approach for the identification of human implicit visual search intention based on eye movement pattern and pupillary analysis such as pupil size, gradient of pupil size variation, fixation length/count for the area of interest. The proposed model identifies the human's implicit intention into three types such as navigational intent generation, informational intent generation, and informational intent disappearance. Navigational intent refers to the search to find something interesting in an input scene with no specific instructions, while informational intent refers to the search to find a particular target object at a specific location in the input scene. In the present study, based on the human eye movement pattern and pupillary analysis, we used a hierarchical support vector machine which can detect the transitions between the different implicit intents - navigational intent generation to informational intent generation and informational intent disappearance.

최근에 사용자 행태 분석 개념이 매우 중요한 이슈가 되고 있다. 하지만 SE(Software Engineering)와 HCI(Human-Computer Interaction) 두 분야의 틈으로 HCI 관점의 시스템 모델링을 위한 적절한 모델링 언어나 도구가 부족하다. 그리고 원시 데이터를 분석하여 사용자 행위를 모델링하는 것은 실제로 어려운 작업이다. 이 논문에서는 목적(Goal)지향의 사용자 행위 분석을 통해 객체를 식별하고, 추출한 공통/비공통 행위를 기반으로 시스템을 모델링 하고자 UBA(User Behavior Analysis)방법론을 제안한다. 그리고 유비쿼터스 환경의 홈 네트워크 인터페이스 모델을 적용 사례로 언급하였다.

Visual communication is widely used and enhanced in modern society, where there is an increasing demand for spirituality. Museum robots are one of many service robots that can replace humans to provide services such as display, interpretation and dialogue. For the improvement of museum guide robots, the paper proposes a human-robot interaction system based on visual communication skills. The system is based on a deep neural mesh structure and utilizes theoretical analysis of computer vision to introduce a Tiny+CBAM mesh structure in the gesture recognition component. This combines basic gestures and gesture states to design and evaluate gesture actions. The test results indicated that the improved Tiny+CBAM mesh structure could enhance the mean average precision value by 13.56% while maintaining a loss of less than 3 frames per second during static basic gesture recognition. After testing the system's dynamic gesture performance, it was found to be over 95% accurate for all items except double click. Additionally, it was 100% accurate for the action displayed on the current page.

본 논문에서는 바이러스와 같은 생화학 물질의 분자구조를 3 차원 모델로 시각화하여 관찰하고, 그 분자모델을 직관적인 방법으로 조작하기 위한 가상 현실 분자 모델링 시스템을 제안한다. 이 시스템을 사용하면, 입체영상 디스플레이 장치와 데이터 글러브 및 동작 추적 장치를 사용하여 3 차원 분자 모델을 실감나게 조작할 수 있어서 효율적으로 분자들을 관찰하고 결합, 분리하는 등의 분자 모델링 작업이 가능하다. 사용자들은 마우스나 키보드 등의 장비 대신에 자연스러운 몸 동작이나 손 동작을 이용하여 분자 모델링 작업을 위한 동작을 하게 된다. 분자들의 결합을 화학적으로 정확하게, 그리고 실시간으로 시뮬레이션 하기 위해서 에너지 계산 알고리즘을 구현하였으며 이러한 작업이 가능하도록 분자 구조를 표현하는 새로운 자료구조를 제안하였다. 본 연구에서 제안하는 동작 기반의 VR 분자 모델링 시스템의 타당성을 검증하기 위하여 HIV 바이러스 분자를 가지고 분자 모델링 작업을 수행하였고, 사용자 테스트를 실시하여 기존의 방식과 작업 성능 및 사용자 만족도를 비교하였다.

Recently, augmented reality is divided into broadly marker based and markerless based as part of HCI (Human Computer Interaction). Markerless based is augmented object using natural features in real-world environment. On the other hand, Marker based is use to calculate easily the coordinates and exactly augmented object using flat marker of rectangular. However, marker-based image is provided due to the presence of the marker in a markerless, giving users a more less realistic and immersive view. In this paper, We research about combined diminished reality and augmented reality for Marker-Based Augmented Reality System Structure using Object Removal Tchnique in order to increase realistic and immersive view.

In this paper, we describe interactive contents which is used the result of the inputted interface recognizing vision-based body gesture. Because the content uses the imp which is the common culture as the subject in Asia, we can enjoy it with culture familiarity. And also since the player can use their own gesture to fight with the imp in the game, they are naturally absorbed in the game. And the users can choose the multiple endings of the contents in the end of the scenario. In the part of the gesture recognition, KINECT is used to obtain the three-dimensional coordinates of each joint of the limb to capture the static pose of the actions. The vision-based 3D human pose recognition technology is used to method for convey human gesture in HCI(Human-Computer Interaction). 2D pose model based recognition method recognizes simple 2D human pose in particular environment On the other hand, 3D pose model which describes 3D human body skeletal structure can recognize more complex 3D pose than 2D pose model in because it can use joint angle and shape information of body part Because gestures can be presented through sequential static poses, we recognize the gestures which are configured poses by using HMM In this paper, we describe the interactive content which is used as input interface by using gesture recognition result. So, we can control the contents using only user's gestures naturally. And we intended to improve the immersion and the interest by using the imp who is used real-time interaction with user.

The IPTV which was commercialized and is being serviced to customers at present has a complicated GUI (Graphical User Interface) to provide two-way services and a remote control containing more than 40 buttons unlike the conventional TV. Accordingly, the remote control becomes one of the causes that make the usability of the IPTV worsen. In this paper, we suggest a LED button guide system as a solution to improve a usability of the IPTV, and analyze the effects of the interface obtained from the user evaluation on the user action.

본 논문은 픽토그램(Pictogram)의 시각전달 요소를 재해석하고 증강현실 환경에서의 효율적 전달 방법에 대하여 제안한다. 픽토그램은 국경을 넘어 남녀노소 모두가 인지할 수 있어야 함이 규칙이며 불특정 다수라는 사용자들을 위해 정확한 정보를 담고 있는 시각전달 매체로서 공정성, 객관성을 가지고 디자인 되어야 한다. 사용자에게 정보전달 인식을 높이기 위해 표준 픽토그램 과 문화 속에서 발견할 수 있는 행위들을 접목하여 애니메이션으로 제작하고, 이를 다양한 연구분야에서 응용되고 있는 증강현실 (Augmented Reality 또는 AR) 기술에 적용하여 표현하였다. 증강현실은 사용자-콘텐츠 정보전달 매체로서 현실 환경을 기반으로 하는 3 차원공간의 시각정보에 대한 사용자의 인식을 향상시킬 수 있는 방법으로 인간-컴퓨터 상호작용(Human-Computer Interaction)을 제공한다. 본 논문에서 제시된 픽토메이션은 기존 공공장소 어디서나 만날 수 있는 다양한 픽토그램을 패턴화하여 마커로 활용하고 사용자는 현재 널리 보급되고 있는 UMPC 혹은 PDA를 통하여 증강현실 환경에서 제작된 픽토메이션 콘텐츠를 경험해 볼 수 있다. 픽토메이션은 시각커뮤니케이션의 효과를 증가 시킬 수 있고, 정보습득의 주체인 사용자에게 콘텐츠의 종류를 예측할 수 있는 선택의 자유를 준다. 본 논문에서는 멀티미디어디자인 요소를 포함한 콘텐츠와의 실시간 상호작용을 통하여 유희적 요소의 접목을 시도하고 증강현실환경에서 Pictomation을 통하여 사용자들과의 효과적 커뮤니케이션을 위한 방법을 모색하고자 한다.
