We present a method for tracking and interaction based on hybrid sensing for virtual environments. The proposed method is applied to motion tracking of whole areas, including the user's occlusion space, for a high-precision interaction. For real-time motion tracking surrounding a user, we estimate each joint position in the human body using a combination of a depth sensor and a wand-type physical user interface, which is necessary to convert gyroscope and acceleration values into positional data. Additionally, we construct virtual contents and evaluate the validity of results related to hybrid sensing-based whole-body tracking of human motion methods used to compensate for the occluded areas.

디자인 프로세스의 초기단계에서 컨셉 디자인은 창의적인 아이디어 발상이 요구되는 단계로 제품의 성공과 실패여부를 조기에 판가름 할 정도로 중요한 일이다. 이를 위해 개발된 웹 기반 창의적 발상 시스템(Creative Group Thinking System:이하 CGTS)은 이와 같은 컨셉디자인 단계에서 아이디어 발상을 지원하기위해 개발된 것이다. 따라서 본 연구는 HCI(Human Computer Interface)와 UI(User Interface)에 대하여 알아보고 이를 토대로 하나의 웹 기반 발상시스템(CGTS)의 UserInterface(이하 UI)를 개선하여 사용성을 높이는데 목적을 둔다.

박근혜정부의 창조경제는 국민을 창조활동의 주인공으로 자리매김함으로써 기존의 전문가 중심, 과학기술공급중심의 경제사회발전전략과는 다른 특성을 보여주고 있으나 그 해석과 정책 실행에 있어 그 특징을 찾아보기 어렵다. 본 연구는 창조경제가 주목한 국민의 창의성이 과학기술자의 창의성과 무엇이 다르며, 그것이 정책 패러다임으로서 어떤 의미를 갖는지 광범위한 문헌 연구를 통해 밝힘으로써 창조경제가 담아내야 할 도전과 과제를 제시하는 것을 목적으로 한다. 국민은 사용자로서의 창의성에 더불어 인문학적, 철학적, 윤리적, 경험적 능력을 바탕으로 한 생활인/삶의 주체로서의 창의성을 갖고 있으며 이것은 과학기술자의 창의성과는 구분되는 고유의 창의성이라 할 수 있다. 사용자로서의 창의성, 생활인/삶의 주체로서의 창의성의 발현은 삶의 가치에 대한 선택을 내포하며 이는 소비행태의 변화, 삶의 방식의 변화를 통해 기술 고착, 사용자 고착을 타파함으로써 시스템 혁신을 이루거나 새로운 사회 기술시스템의 구성 혹은 전환을 촉진할 수 있다. 이런 맥락에서 국민의 창의성은 기존의 전문가/과학기술 공급중심 혁신 패러다임이 아닌 사용자/현장중심 혁신 패러다임'의 토대로서 역할 할 수 있다. 따라서 국민의 창의성에 주목하고 있는 창조경제는 사용자/현장 중심 혁신 패러다임의 실현이라는 새로운 경제사회발전정책과제를 안고 있다고 할 수 있다.

이미지 생성형 AI의 등장으로 미술, 디자인 전문가가 아니어도 텍스트 입력을 통해 완성도 높은 그림 작품을 만들 수 있게 되었다. 생성 이미지의 활용 가능성과 예술 산업에 미치는 영향력이 높아짐에 따라 사용자가 AI와 공동 창작하는 과정을 어떻게 인식하는지에 대해 연구 필요성이 제기되고 있다. 이에 본 연구에서는 일반 사용자들을 대상으로 이미지 생성형 AI 창작에 대한 예상 과정과 체감 과정을 알아보고 어떤 과정이 사용자의 창작 주체감에 영향을 미치는지 알아보는 실험 연구를 진행하였다. 연구 결과 사용자들이 기대한 창작 과정과 체감한 창작 과정 간 격차가 있는 것으로 나타났으며 창작 주체감은 낮게 인식하는 경향을 보였다. 이에 AI가 사용자의 창작 의도를 지원하는 조력자의 역할로 작용하여 사용자가 높은 창작 주체감을 경험할 수 있도록 8가지 방법을 제언한다. 본 연구를 통해 사용자 중심적인 창작 경험을 고려하여 향후 이미지 생성형 AI의 발전에 기여할 수 있다.

In this letter, we propose a dual autostereoscopic display platform employing a natural interaction method, which will be useful for sharing visual data with users. To provide 3D visualization of a model to users who collaborate with each other, a beamsplitter is used with a pair of autostereoscopic displays, providing a visual illusion of a floating 3D image. To interact with the virtual object, we track the user's hands with a depth camera. The gesture recognition technique we use operates without any initialization process, such as specific poses or gestures, and supports several commands to control virtual objects by gesture recognition. Experiment results show that our system performs well in visualizing 3D models in real-time and handling them under unconstrained conditions, such as complicated backgrounds or a user wearing short sleeves.

The purpose of this study is to analyze on high school teachers' stage of concern(SoC) on 'Creative-Experience Activity' in 2009 revised national curriculum and investigate the improvements of their levels. The subjects for this study were 234 high school teachers through out all part of the Korea country. The instrument for this study was developed according to the Hall & Hord(2006)'s stage of concerns questionnaire of Stage of Concern. The Data were analyzed by Profiling of teachers' concern and one-way ANOVA. The major findings of this study were as follows: First, 85.25% of the high school teachers were in stage of Awareness. 6.34% of teachers were in stage of Information. Most of high school teachers' concern about 'Creative-Experience Activity' was generally 'non-user' stage that unconcerned. Second, there were not significant differences in teachers' stage of concern according to their sex and teaching career except for region. In region, the teacher in metropolis tent to interest getting new information than small and midium size city. We need to make an effort to transfer from 'non-user' stage to 'early-user' stage of and 'impact' stage. To do so, we may sublate too much curriculum revise and start teacher training for 2009 revised 'creativity-experience activity' curriculum. The result of the study provide that there are not curriculum implementation success without teachers' concern about revised curriculum.

Advances in information and telecommunication technology increasingly reveal the potential of computer supported education. However, most computer supported learning systems until recently did not pay much attention to different characteristics of individual learners. Intelligent learning environments adaptive to learner's preferences and tasks are desired. Each learner has different preferences and needs, so it is very crucial to provide the different styles of learners with different learning environments that are more preferred and more efficient to them. This paper reports a study of the intelligent learning environment where the learner's preferences are diagnosed using learner models, and then user interfaces are customized in an adaptive manner to accommodate the preferences. In this research, the learning user interfaces were designed based on a learning-style model by Felder & Silverman, so that different learner preferences are revealed through user interactions with the system. Then, a learning style modeling is done from learner behavior patterns using Decision Tree and Neural Network approaches. In this way, an intelligent learning system adaptive to learning styles can be built. Further research efforts are being made to accommodate various other kinds of learner characteristics such as emotion and motivation as well as learning mastery in providing adaptive learning support.

is a service providing the story synopses that match user's query. This paper analyzes the user log of which is the answers to the queries to find stories from database, and shows the tendency distribution of user creation. Specially, we analyze a joint distribution of the genres and actions of stories to get better understanding of the tendencies that cannot be found in the analysis of independent distribution. Furthermore, we define a correlation factor between genre and action, and investigate what combinations of the genres and actions are highly, less, and negatively correlated. Finally, we investigate how the tendencies of characters are related to genres and actions, and propose a visualization method to show the tendencies.
