It is necessary to evaluate HMI inaspects of human factors in the design stage of MMIS(man machine interface system) and feedback the result of evaluation because operators performance is mainly influenced by the HMI. Therefore, the MMIS design should be reflected the operators psychological, behavioral and physiological characteristics in the interaction with human machine interface(HMI) in order to improve the safety and availability of the MMIS of a nuclear power plant(NPP) by reduction of human error. The development of human factors experimental evaluation techniques and integrated test facility(ITF) for the human factors evaluation become an important research field to resolve hi,am factors issues on the design of an advanced control room(ACR). We developed am ITF, which is aimed to experiment with the design of the ACR and the human machine interaction as it relates to the control of NPP. This paper presents the development of an ITF that consists of three rooms such as main test room(MTR), supporting test room(STR) and experiment control room(ECR). And, the ITF has a various facilities such as a human machine simulator(HMS), experimental measurement systems and data analysis and experiment evaluation supporting system(DAEXESS). The HMS consists of full-scope simulation model of Korean standard NPP and advanced HMI based on visual display nits (VDUS) such as touch color CRT, large scale display panel(LSDP), flat panel display unit and so on.

Driving simulators are useful tools not only to test the components of future cars but also to evaluate the telematics service and HMI (Human-Machine Interface). However driving simulators cannot be implemented to test and evaluate the telematics service system because the GPS (Global Positioning System) which contains basic functional support for the telematics module do not work in the VR (virtual reality) environment. This paper presents a method to implement telematics service to a driving simulator by developing the GPS simulator which is able to emulate GPS satellite signals consist of NMEA-0183 protocol and RS232C communication standards. It is expected that the driving simulator with the GPS simulator can be used to study HMI and human-factor evaluations of the commercial telematics system to realize the HiLES (Human-in-the-Loop Evaluation System).

There is no universally agreed classification of human error, nor is there one in prospect. Thus, a taxonomy is usually made for a specific purpose. To seek the types of human errors in the environment of man-machine interface under the railway industry, we develop a cognitive information processing model incorporating the human's mental states. Using the model, this study investigates the types of human errors about the railway workers. Thus, a survey is conducted for railway safety personnel-locomotive engineers, station employees, and train commanders- in Korean railway company. Through the survey that is designed to investigate four types of human errors from the Questionnaires composed of thirty Questions, we analyze the types of human errors related to railway safety according to affiliated offices, operation shifts, age, and working years. Finally, from the insights of the results some guidelines for the railway safety management are presented.

Objective: This study aims to implement a non-contact gesture-based interface for presentation purposes and to analyze the effect of the proposed interface as information transfer assisted device. Background: Recently, research on control device using gesture recognition or speech recognition is being conducted with rapid technological growth in UI/UX area and appearance of smart service products which requires a new human-machine interface. However, few quantitative researches on practical effects of the new interface type have been done relatively, while activities on system implementation are very popular. Method: The system presented in this study is implemented with KINECT$^{(R)}$ sensor offered by Microsoft Corporation. To investigate whether the proposed system is effective as a presentation support tool or not, we conduct experiments by giving several lectures to 40 participants in both a traditional lecture room(keyboard-based presentation control) and a non-contact gesture-based lecture room(KINECT-based presentation control), evaluating their interests and immersion based on contents of the lecture and lecturing methods, and analyzing their understanding about contents of the lecture. Result: We check that whether the gesture-based presentation system can play effective role as presentation supporting tools or not depending on the level of difficulty of contents using ANOVA. Conclusion: We check that a non-contact gesture-based interface is a meaningful tool as a sportive device when delivering easy and simple information. However, the effect can vary with the contents and the level of difficulty of information provided. Application: The results presented in this paper might help to design a new human-machine(computer) interface for communication support tools.

IVNS(In-Vehicle Navigation System) which developed by the advance of technological system including computer, display and communication will procide the important interface functions between the driver and the ITS (Intelligent Transport System). However, hat the human factors engineer can actually offer to the designer is by no means a complete set of design specifications. Therefore, a set of boundary conditions and operational ranges within which the designer can be assured that physical, perceptual and cognitive abilities and limitations of drivers will be accommodated system atically[6]. Also, this will be the considerations to compose the IVNS HMI (Human-Machine Interface) design guidelines and IVNS HMI evaluation system. As the first phase of developing the IVNS HMI evaluation system, this paper describe the architecture and the content of this system.

In this paper, an interface between a human and a computer is presented. The human and computer interface(HCI) serves as another area of human and machine interfaces. Methods for the HCI we used are voice recognition and image recognition for detecting human's emotional feelings. The idea is that the computer can recognize the present emotional state of the human operator, and amuses him/her in various ways such as turning on musics, searching webs, and talking. For the image recognition process, the human face is captured, and eye and mouth are selected from the facial image for recognition. To train images of the mouth, we use the Hopfield Net. The results show 88%$\sim$92% recognition of the emotion. For the vocal recognition, neural network shows 80%$\sim$98% recognition of voice.

From a viewpoint of human factors, automated highway systems(AHS) can be defined as one of the newly developing human-machine systems that consist of humans(drivers and operators), machines(vehicles and facilities), and environments(roads and roadside environments). AHS will require a changed vehicle control process and driver-vehicle interface(DVI) comparing with conventional driving. This study introduces a fixed-based AHS simulator and provides questionnaire-based human factors evaluation results after three kinds of automated driving speed experiences in terms of road configuration, operation policies, information devices, and overall AHS use. In the simulator, the "shared space-at-grade" concept-based road configuration was virtually implemented on a portion of the Kyungbu highway in Korea, and heads-up display(HUD), AHS information display, and variable message signs(VMS) were installed for appropriate AHS DVI implementation. As the results, the subjects expressed positive opinions on the implemented road configuration, operation policies, and the overall use of AHS. The results of this study would be helpful in developing the road configuration and DVI design guideline as the basic human factors research for the future implementation of AHS.

본 논문은 멀티미디어 서비스를 지원하는 다인승 차량 내 HMI(Human Machine Interface)을 지원하는 네트워크 구조 및 구현방법에 관한 것이다. 다인승 차량의 경우, 기존 승용차의 멀티미디어 서비스형태와 달리 트래픽에 대한 요소를 고려해야하며, 서버에서 업데이트되는 콘텐츠 정보를 다수의 사용자에게 동시에 전달해야하는 특성이 있으며, 사용자가 네트워크에 접속하여 다양한 콘텐츠를 사용할 수 있는 확장성이 있어야한다. 따라서 본 논문에서는 기존 차량용 광 네트워크 MOST(Media Oriented System Transport) 시스템 구조를 변경하여 MOST와 연동되는 이더넷 기능을 개발하고 사용자 접근할 수 있는 인터페이스를 설계하여 다인승 차량용 멀티디미어 서비스에 필요한 데이터송수신 모듈 설계 방법을 제안한다.

산업용 HMI(Human Machine Interface) 시스템은 공장 자동화의 주요 구성요소 중 하나로서 PLC와 연결되어 자동화 설비 또는 장치의 운전 상태를 감시하고 제어하는데 사용된다. 이러한 HMI는 주로 제조업체별로 특정한 시스템을 사용하고, 근거리에 위치하여 쓰이기 때문에 시스템 개발 시 많은 부하를 주게 되고 시스템 확장이 어려운 단점이 있다. 이에 본 논문에서는 오픈 소스인 임베디드 리눅스 기반에 멀티 플랫폼을 지원하는 Qt/Embedded와 무선 통신 모듈을 사용하여 터치패널형 산업용 HMI 소프트웨어 모듈을 설계 및 구현하였다. 이 모듈은 Qt가 지원되는 시스템이면 소스 수정 없이 사용할 수 있으며 무선 랜 모듈을 이용하여 시스템의 이동성 및 네트워크 구축 및 시스템 확장을 보다 유동성 있게 설계할 수 있다. 이에, 리눅스 기반의 무선통신이 가능한 HMI 소프트웨어 모듈 구현으로 이동성 확보 및 범용 운영체제의 사용으로 인한 시스템 개발 시 부하 감소와 가격 경쟁력의 향상을 이루게 되었다.
