본 논문은 현재 영역 별로 파편화된 여러 O2O(Online to Offline) 서비스들을 통합적으로 제공하기 위해 자연어를 통한 NUI(Natural User Interface)를 개발하여 사용자가 명시한 상품 정보의 항목을 자동으로 분류하고자 한다. 이를 위해 e-commerce 도메인 정보 학습에 적합한 나이브 베이즈 분류(Naive Bayes Classifier) 알고리즘을 사용한다. 학습에는 미국 e-commerce 사이트 Groupon의 상품 정보와 분류 체계를 사용하며, 학습 데이터의 특징을 분석하여 상품 정보에 특화된 학습 데이터 정제 및 TF-IDF(Term Frequency-Inverse Document Frequency)를 통한 단어 별 가중치를 적용하여 알고리즘의 정확도를 향상시킨다.

실시간 운영체제 GUI 에서 가장 중점적인 것은 임베디드 시스템상에서 중요한 자원 중 하나인 메모리의 효율적인 관리이다. 특히 파일시스템이 없는 임베디드 시스템의 경우 GUI 를 사용하게 되면 폰트 이미지(Font Image)와 그림파일 등이 메모리상에 존재하여야 하기 때문에 메모리를 많이 차지하게 된다. 본 논문에서는 실시간 운영체제 $UbiFOS^{TM}$에서 파일시스템 모듈을 제거하고 GUI 를 설계 및 구현하였고 특히 폰트 이미지와 그림파일을 처리하는 방법과 폰트 이미지를 위한 메모리를 절약할 수 있는 메커니즘을 제안하였다.

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.

This paper provides a user interface for mutual collaboration table top display technology. The biggest difference is that the existing interface with existing research through a single device to multiple users simultaneously enabled oriented way of face to face. On the other hand, in collaboration important deadline table top display device to device-oriented approach in which the order of one of the devices require users. Collaborative research is actively underway, but to do so focused still many challenges in this situation. This paper provides for collaboration on global trends on a table top display interface for more mutual collaboration with the user interface for about checking out on a table top display, currently being developed by a collaboration among users against a table top display technology.

현대의 PC 환경에서 사용자 인터페이스의 변화는 계속하여 발전할 것으로 기대된다. HCI 전용 인터페이스는 종래의 CLI; Command Line Interface의 시대에서 MS-Windows 기반의 Graphic User Interface의 시대로 전환되어 왔으며, 가까운 미래에는 NUI; Natural User Interface의 시대로 도래함은 부정할 수 없는 현실이다. 미래에는 전통적인 표준 입력 장치인 키보드, 마우스를 탈피하여 새로운 개념의 입력 장치들이 개발되고, 터치 방식과 같이 인간의 직관적 인지능력을 흉내 낸 인터페이스로 발전할 것이다. 본 논문에서는 NUI의 사례 연구로서 닌텐도 WiiRemote를 Bluetooth와 함께 PC에 연동하여 차세대 인터페이스인 PC Controller를 설계, 사람 제스처를 통한 자연스런 한글입력의 가능성을 제안한다.

Virtual reality(VR) is known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence and environment to allow for user interaction. Virtual realities artificially create sensory experience including sight, touch, hearing, and smell. Owing to the use of a single device in most VR contents, user have difficulty in manipulating user interface and game object. And also immersion of the game goes down because they can't see the mouse and keyboard in virtual space. In this paper, we design and implement the chess game to easily and accurately control user interface to improve the immersion in game.

Graphic User Interface has been playing a great role in giving people easy access of computer. The research of implementing graphic image on the computer display and inventing mouse were the threshold of GUI's birth in 1960s, and those were succeeded to developing the first GUI based-computer at the Xerox research center in 1970s. An education theory for the children and the visual metaphor of real life environment were adapted to implement GUI. They were continuously studied and tested in the beginning of creating the GUI concept and design method. In 1980s, the GUI concept and design method were generally applied to all personal computer development. Apple and Microsoft have led the commercialization of their GUI based-05, and also got their own positions in the market as GUI standards in 1990s. The first research for the GUI based-computer implementation in Xerox has established very clear concept and design methods. This GUI standards are evolving Into more convenient and natural ways in various computing environment and developing technologies these days.

Recently, the infrastructure to be connected to the internet is much provided, there is more and more need to connect electric or electronic products to the internet to monitor or control them remotely. However, most of the existing products lack the network interface, so it was very inconvenient to be connected to the internet. Therefore, this article designs and realizes the internet outlet allowing real-time scheduling that can control the power remotely on the internet by using the hardware TCP/IP processor. The realized product consumes low production cost because it can be realized by using the hardware TCP/IP processor and the 8-bit small microprocessor. In addition, the product can be used widely in both wired and wireless environments with a variety of user interface, including the dedicated control program which provides the environment configuration functions; embedded web service that enables the webpage to be saved on the external flash memory; Android smartphone application; motion recognition control environment that uses the OpenCV computer vision library, etc.

Recently, various kinds of new computer controlled devices have been introduced in a wide range of areas, and convenient user interfaces for controlling the devices are strongly needed. To implement natural user interfaces(NUIs) on top of the devices, new technologies like a touch screen, Wii Remote, wearable interfaces, and Microsoft Kinect were presented. This paper presents a natural and intuitive gesture-based model for controlling contents of LCD display. Microsoft Kinect sensor and its SDK are used to recognize human gestures, and the gestures are interpreted into corresponding commands to be executed. A command dispatch model is also proposed in order to handle the commands more naturally. I expect the proposed interface can be used in various fields, including display contents control.

Human body motion is a non-verbal part for interaction or movement that can be used to involves real world and virtual world. In this paper, we explain a study on natural user interface (NUI) in human hand motion recognition using RGB color information and depth information by Kinect camera from Microsoft Corporation. To achieve the goal, hand tracking and gesture recognition have no major dependencies of the work environment, lighting or users' skin color, libraries of particular use for natural interaction and Kinect device, which serves to provide RGB images of the environment and the depth map of the scene were used. An improved Camshift tracking algorithm is used to tracking hand motion, the experimental results show out it has better performance than Camshift algorithm, and it has higher stability and accuracy as well.
