최근 다양한 3차원 콘텐츠 및 응용 프로그램의 개발되고, 컴퓨터 사용자 계층이 다양화됨으로 인하여 인터페이스에 대한 연구가 활발히 진행되고 있다. 본 연구는 사용자가 손을 이용하여 윈도우를 효율적으로 제어할 수 있도록 하는 것을 목적으로 한다. 기존 인터페이스에 관한 연구들은 고가의 장비를 사용하거나 복잡한 제스처 인식, 또는 부가적인 도구인 마커 등을 사용하는 문제가 있다. 이러한 단점을 개선하기 위하여 새로운 시각적 비접촉 인터페이스를 제안한다. 손을 사용하여 윈도우를 제어하기 위하여 HSV 색상공간을 이용하여 손 영역을 검출한다. 그리고 거리변환 행렬과 손 외곽선의 곡률을 이용하여 손의 중심과 손가락의 위치를 파악한다. 손의 중심과 손가락 위치를 이용하여 본 논문에서 제안하는 7가지의 제어 동작 중 사용자가 의도하는 동작을 파악하여 인터페이스로써 활용한다. 제안하는 인터페이스는 스테레오 카메라를 사용함으로써 사유자가 3차원 공간에서 거리감을 가지고 제어할 수 있도록 하였다. 그리고 간단한 손동작으로 제어하고자 하는 객체를 시각적으로 접촉할 수 있도록 함으로써 직관적인 제어가 가능하도록 하였다. 마지막으로 제안하는 인터페이스를 활용한 응용을 통해서 효율성을 확인한다.

인간 대 컴퓨터 인터페이스의 발전은 기술의 발전에 크게 의존되어 왔다. 그러나 인위적 환경을 통한 커뮤니케이션 방법인 키보드, 마우스나 OMR 등의 비직관적 인터페이스를 넘어선 직관적 인터페이스의 연구가 활발히 진행되고 있다. 이와 더불어 일반 가정에서도 대형화면 TV의 급속한 보급과 디지털환경을 통한 다양한 서비스의 제공이 이뤄지고 있다. 이러한 인터페이스와 TV환경의 변화는 인간 대 TV의 인터페이스에 획기적 변화를 요구하게 되었다. 기존의 인터페이스에서 동작인식을 기반으로 하는 인터페이스로의 전환은 보다 직관적인 인터페이스로서 제시될 수 있을 것이다. 본 연구에서는 지시동작인식이론과 디지털 TV 인터페이스 분석에 대한 이론을 바탕으로, 이에 요구되는 최소기능 추출 후 인터뷰를 통해 추출된 지시동작을 분석하는 기초적 연구이다. 이를 통해 디지털 TV에서 요구되어지는 특정 기능에 대한 동작모형을 제시하여 이에 적합한 인터페이스 환경을 디자인하는데 대한 기초자료로 활용하고자 한다.

The purpose of this study was to develop a personalized SMT (smart monitor target) game interface for game users who enjoy airsoft sports as individual purchases of SMT have increased since the advent of the untouched era. For this study, the UX (user experience) of the game interface was designed based on previous research. In particular, the personalized game service was reinforced by adding the CP (command post) of the SMT system that performs the home function of the console game, which was intended to help the user maintain immersed in the game in the personalized space of the SMT. Major design elements for the SMT game interface included layout, color, graphics, buttons, and text, and the interface design was proceeded based on them. After composing a grid with a layout in which the tab function was applied to the interface with a vertical three-segment structure and the outer margin value secured, the military camouflage pattern and texture were applied to the colored tone to perform graphics work. Targets and thumbnails were produced as illustrations using experts to ensure the consistency of the interface, and then function buttons and texts on each page were used concisely for intuitive information delivery. The design sources organized in this way were developed using the Unity engine. In the future, we hope that game user-centered personalized interfaces will continue to develop and provide differentiated services unique to SMT systems in the airsoft gun market.

In this paper, we developed a low cost smart puck system that can interact with the intuitive operation of natural finger touches. The tangible smart puck, designed for capacitive tabletop display, has Arduino embedded processor which communicates only with the MT server. The MT server communicates both to the smart puck and the display server. The display server displays the relevance information on the location of the smart pucks on the tabletop display and handles interactions with the users. The experiment results show that the accuracy of identifying the smart puck ID was very reliable enough to use in practice, and the information presentation processing time is confirmed excellent enough compared to traditional expensive commercial products.

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.

In this paper we present 3-D Navigation View, a three-dimensional visualization of indoor environment which serves as an intuitive and unified user interface for our developed indoor location tracking system via Virtual Reality Modeling Language (VRML) in web environment. The extracted user's spatial information from indoor location tracking system was further processed to facilitate the location indication in virtual 3-D indoor environment based on his location in physical world. External Authoring Interface (EAI) provided by VRML enables the integration of interactive 3-D graphics into web and direct communication with the encapsulated Java applet to update position and viewpoint of user periodically in 3-D indoor environment. As any web browser with VRML viewer plug-in is able to run the platform independent 3-D Navigation View, specialized and expensive hardware or software can be disregarded.

현재 NUI(Natural User Interface)는 차세대 입력 방식으로 주목을 받고 있다. 이미 한글 입력에 관한 NUI가 다양하게 연구 및 개발되고 있지만, 한글 입력 NUI는 직관성과 정확도의 부족과 불완전한 인식률 등의 한계점이 존재한다. 본 연구에서는 사용자의 핸드 제스처를 인식하기 위해 Leap Motion 장치를 사용하고, 한글의 글자 조합 원리를 바탕으로 자음과 모음 입력의 제스처를 분리하여 인식의 정확도를 높인다. 그리고 모음의 방향성을 참고하여 한글 입력에 직관성을 향상할 수 있는 핸드 제스처를 연구한다. 이를 통해 사용자가 NUI 환경의 디바이스를 좀 더 정확하고 빠르게 조작할 수 있도록 돕는다.

As computer performance and needs of user convenience increase, computer user interface are also changing. This changes had great effects on software development environment. In past, text editors like vi or emacs on UNIX OS were the main development environment. These editors are very strong to edit source code, but difficult and not intuitive compared to GUI(Graphical User Interface) based environment and were used by only some experts. Moreover, the trends of software development environment was changed from command line to GUI environment and GUI Editor provides usability and efficiency. As a result, the usage of text based editor had decreased. However, because GUI based editor use a lot of computer resources, computer performance and efficiency are decreasing. The more contents are, the more time to verify and display the contents it takes. In this paper, we provide a new parser that provide multi view editing, incremental parsing and multiple entry of abstract syntax tree.

NUI is a motion interface. It uses the body of the user without the use of HID device such as a mouse and keyboard to control the device. In this paper, we use a Pi Camera and sensors connected to it with small embedded board Raspberry Pi. We are using the OpenCV algorithms optimized for image recognition and computer vision compared with traditional HID equipment and to implement a more human-friendly and intuitive interface NUI devices. comparison operation detects motion, it proposed a more advanced motion sensors and recognition systems fused connected to the Raspberry Pi.

Nanoscale task such as nanolithography and nanoindenting is a challenging work that is beyond the capabilities of human sensing and precision. Since surface forces and intermolecular forces dominate over gravitational and other more intuitive forces of the macro world at the nanoscale, a user is not familiar with these novel nanoforce effects. In order to overcome this scaling barrier, haptic interfaces that consist of visual and force feedback at the macro world have been used with an Atomic Force Microscope (AFM) as a manipulator at the nanoscale. In this paper, a nanoscale virtual coupling (NSVC) concept is introduced and the relationship between performance and impedance scaling factors of velocity (or position) and force are explicitly represented. Experiments have been performed for nanoindenting and nanolithography with different materials in the nanoscale virtual surface. The interaction forces (non contact and contact nanoforces) between the AFM tip and the nano sample are transmitted to the operator through the haptic interface.
