본 논문에서는 Error Back Propagation 학습을 이용해 한글 문자를 On-Line 인식하는 시스템을 제안한다. Pointing device의 궤적을 추적해 입력 패턴의 특징(feature)을 추출해 신경 회로망 입력으로 준다. 이때 사용하는 특징은 기본 획 (stroke)의 종류 및 획간의 상대적 위치 관계이다. 학습과정에서는 자소의 정의를 읽어 초성, 중성, 종성에 대해 각 획수마다 정의된 신경회로망의 weight를 조정한다. 인식 과정에서는 초성, 중성, 종성의 순으로 에러가 최소인 획수의 신경회로망 출력을 택하여 2 바이트 조합형 코드로 완성한다. 이로써 Intelligent Man-Machine Interface 시스템중 위치 및 크기에 무관한 전필 입력 시스템을 구현한다.

자동차 man-machine system의 interface를 이루는 Display panel, Center fascia, Steering wheel, Rear view, Gear, Power window switch, Seat 등과 이들의 Layout은 운전자의 안전뿐만 아니라, 안락감과 밀접한 부분으로 알려져 있다. 따라서 이러한 설계요소들의 Man-machine interface의 최적화를 위한 인간공학적 접근이 필요하다. 운전자의 안락감은 Seat, Pedal, Steering wheel 등 뿐만 아니라 각종 조작장치(Audio, Switch, Gear,…)도 함께 연구되어야 하다. 따라서, 본 연구에서는 실험용 Seating buck을 제작하여 실내 조작장치 중 오디오를 대상으로 터치스크린과 Rapid Prototype을 이용해 사용성 평가에 대한 적합성을 검증하고자 하였다. Rapid Prototyping 기법은 디자인단계에서 제품 사용상의 문제점을 발견 개선할 수 있다는 장점이 있다. 그러나, 본 연구 결과에서 3가지 항목 중 1가지만이 실제 Audio와 Prototype에서 차이가 없었다. 따라서, Prototype의 접촉감과 입체감의 개선, 실사용과 동일한 환경의 제시, 소리와 같은 정확한 반응의 제시, Glare의 제거, 사용자 분석에 따른 실험 데이터의 축적 등을 고려하여 Rapid Prototyping을 구현하여야 할 것이다.

인간-기계시스템(Man-Machine System)의 구조가 점점 복잡해짐에 따라 제품의 설계단계에서 인간과 시스템간의 상호작용(interaction)을 고려하기 위하여 인간-기계 인터페이스모형(Man-Machine Interface Model)의 개발 필요성이 대두되고 있다. 본 연구에서는 인체모형과 관련된 인체변수들을 추출하여 Database화한 후, AutoCAD를 이용하여 컴퓨터로 구현하였다. 인체모형의 구축에서는 Robotics에서 사용하는 Denavit-Hartenberg Notation과 같은 체계적인 좌표계를 이용하여 기존의 인체모형 연구결과들을 쉽게 적용할 수 있도록 하였다. 한편, 본 인체모형은 범용 CAD Package인 AutoCAD를 이용하여 구현함으로써 SAMME등에서 볼 수 있는 인간공학적 평가를 PC수준에서 가능하도록 하였다. 본 시스템을 이용함으로써 제품의 설계단계에서부터 인간공학적 요소들을 고려할 수 있을 뿐만아니라 기존 제품의 평가에도 유용하게 사용할 수 있으리라 기대된다. 한국인을 대상으로 한 인체모형의 개발이라는 점에서 의의가 있다고 할 수 있다.

We aim to reinterpret Bong Joon-ho's Snowpiercer through theory of posthumanism. Posthuman is a compound word of 'post' and 'human', which means transcendent-man. However, we would like to extend the meaning of posthuman or cyborgs as not only to "new human figure, or transcendent-man" but as to "human living in a digital age of converged technology". Through the extension of the meaning of posthuman, we would be able to not only find posthuman in Science Fiction movies but also apply it to our real world. Also, through the extended meaning, we will reinterpret all the elements from the film as cyberspace and as posthuman or cyborgs. Moreover, through examination of these "cyborg figures" in Bong Joon-ho's Snowpiercer (2013), we argue that the film is criticizing posthumanism in the reality that these days, people are losing the humanity due to the combination with the machine. It seems that he claims of the collapse of the current system, suggesting new human generation as the solution.

The analysis of human arm motion during steering maneuver is carried out for investigation of man-machine interface of driver and steering system Each arm is modeled as interconnection of upper arm, lower arm, and hand by rotational joints that can properly represents permissible joint motion, and both arms are connected to a steering wheel through spring and damper at the contact points. The joint motion law during steering motion is determined through the measurement of each arm movement, and subsequent inverse kinematic analysis. Combining the joint motion law and inverse dynamic analysis, joint stiffness of arm is estimated. Arm dynamic analysis model for steering maneuver is setup, and is validated through the comparison with experimentally measured data, which shows relatively good agreement. To demonstrate the usefulness of the arm model, it is applied to study the effect of steering column angle on the steering motion.

In the era of ubiquitous computing, human-friendly man-machine interface is getting more attention due to its possibility to offer convenient services. For this, in this paper, we introduce a 'Half-Mirror Interface System (HMIS)' as a novel type of human-friendly man-machine interfaces. Basically, HMIS consists of half-mirror, USB-Webcam, microphone, 2ch-speaker, and high-speed processing unit. In our HMIS, two principal operation modes are selected by the existence of the user in front of it. The first one, 'mirror-mode', is activated when the user's face is detected via USB-Webcam. In this mode, HMIS provides three basic functions such as 1) make-up assistance by magnifying an interested facial component and TTS (Text-To-Speech) guide for appropriate make-up, 2) Daily weather information provider via WWW service, 3) Health monitoring/diagnosis service using Chinese medicine knowledge. The second one, 'display-mode' is designed to show decorative pictures, family photos, art paintings and so on. This mode is activated when the user's face is not detected for a time being. In display-mode, we also added a 'healing-window' function and 'healing-music player' function for user's psychological comfort and/or relaxation. All these functions are accessible by commercially available voice synthesis/recognition package.

In accordance with increase, if electronic power demanded, more efficient supervisory control of distribution system will be required. This study contains development of MMI(man-machine-interface) system with GUI(graphic-user-interface), for the automatic power distribution system. The main function of MMI system is to edit network of power distribution and to management of data base for network. The GUI function of MMI system enables more efficient management of power distribution system.

An intelligent robot, which has been developed recently, is no more a conventional robot widely known as an industrial robot. It is a computer system embedded in a machine and utilizes the machine as a medium not only for the communication between the human and the computer but also for the physical interaction among the human, the computer and their environment. Recent advances in computer technology have made it possible to create several of new types of human-computer interaction which are realized by utilizing intelligent machines. There is a continuing need for better understanding of how to design human/robot interface(HRI) to make for a more natural and efficient flow of information and feedback between robot systems and their users in both directions. In this paper, we explain the concept and the scope of HRI and review the current research trends of domestic and foreign HRL. The recommended research directions in the near future are also discussed based upon a comparative study of domestic and foreign HRI technology.
