This paper presents a user interface for vision based indirect teaching of a robotic manipulator with Kinect and IMU (Inertial Measurement Unit) sensors. The user interface system is designed to control the manipulator more easily in joint space, Cartesian space and tool frame. We use the skeleton data of the user from Kinect and Wrist-mounted IMU sensors to calculate the user's joint angles and wrist movement for robot control. The interface system proposed in this paper allows the user to teach the manipulator without a pre-programming process. This will improve the teaching time of the robot and eventually enable increased productivity. Simulation and experimental results are presented to verify the performance of the robot control and interface system.

최근 국내외에서 확산되고 있는 RPA(Robotic Process Automation) 솔루션은 사용자가 응용프로그램의 GUI(Graphic User Interface)에서 대상 업무를 간편하게 자동화 할 수 있어 국내 다수 금융회사에서도 동 솔루션을 적용하는 사례가 지속적으로 증가하고 있다. 하지만 금융기관이 반드시 준수해야 하는 주요 감독규제들은 기존 전통적인 SDLC(Software Development Life Cycle)를 기반으로 하고 있어 일반 사용자의 시스템 Interface 환경 단에서 자동화하는 RPA에 그대로 적용되기에는 어려움이 있었다. 이에 본 논문에서는 금융회사가 RPA를 도입함에 있어 고려되어야 하는 주요 감독규정들과 통제항목들을 정리하고 RPA를 도입한 24개 금융회사의 통제 적용현황을 조사하여 향후 관련 컴플라이언스의 개정 필요성을 제시해보고자 한다.

본 논문에서는 지능형 휠체어를 위한 시선 인식 인터페이스에 대해 제안한다. 시선 인식 인터페이스는 조이스틱을 움직이기 힘든 중증 장애인을 위해 시선 인식 및 추적을 이용하여 전동휠체어를 움직일 수 있게 하는 사용자 인터페이스이다. 지능형 휠체어는 시선인식 및 추적 모듈, 사용자 인터페이스, 장애물 회피 모듈, 모터 제어 모듈, 초음파 센서 모듈로 구성된다. 시선인식 및 추적 모듈은 적외선 카메라와 두개의 광원으로 사용자 눈의 각막 표면에 두 개의 반사점을 생성하고, 중심점을 구한 뒤, 동공의 중심점과 두 반사점의 중심을 이용하여 시선을 인식하고 추적 한다. 제안된 방법의 시선 인식 인터페이스는 실험을 통해 시선을 이용하여 지능형 휠체어에 명령을 하달하고 지능형 휠체어가 임의로 설치된 장애물을 감지하고 정확하게 장애물을 회피 할 수 있음을 보였다.

For real-time flood forecasting and effective control flood at the Youngsan estuary dam, the Flood Forecasting and Control User Interface System II (FFCUS II) has been developed. This paper describes the features and application of FFCUS II. FFCUS II is composed of the database management subsystem, the model subsystem, and the graphic user interface. The database management subsyem collects rainfall data and stream flow data, updates, processes, and searches the data. The model subsystem predicts the inflow hydrograph, the tide, forecasts flood hydrograph, and simulates the release rate from the sluice gates. The graphic user interface subsystem aids the user's decision-making process by displaying the operation results of the database management subsystem and model subsystem.

In this paper, we propose robot control interface using gaze recognition which is not limited by head motion. Most of the existing gaze recognition methods are working well only if the head is fixed. Furthermore the methods require a correction process per each person. The interface in this paper uses a camera with built-in infrared filter and 2 LED light sources to see what direction the pupils turn to and can send command codes to control the system, thus it doesn't need any correction process per each person. The experimental results showed that the proposed interface can control the system exactly by recognizing user's gaze direction.

Image morphing deals with the metamorphosis of one image into another. The field morphing depends on the manual work for most of the process, where a user has to designate the control lines. It takes time and requires skills to have fine quality results. It is an object of this paper to propose a method capable of realizing the semi-automation of field morphing using adaptive vertex correspondence based on image segmentation. The adaptive vertex correspondence process efficiently generates a pair of control lines by adaptively selecting reference partial contours based on the number of vertices that are included in the partial contour of the source morphing object and in the partial contour of the destination morphing object, in the pair of the partial contour designated by external control points through user input. The proposed method generates visually fluid morphs and warps with an easy-to-use interface. According to the proposed method, a user can shorten the time to set control lines and even an unskilled user can obtain natural morphing results as he or she designates a small number of external control points.

A real time process control package was developed in an INTEL 80386 based PC and MS OS/2 environment using MS-C and MS-FORTRAN. RTACS(Real Time Advanced Control System), process control computer software for distributed or centralized architectures, is a package which meets functional requirements specified for typical continuous process applications like chemical processes. The package consists of 5 parts, which are DB(data base), OCF(Operator Console Functions), CL (Control logic Library), MSM(Multitasking and Scheduling, Manager) and UAI(User Applications Interface), based upon a table and function block architecture to improve the system performance.
