Human driver monitoring system is one of the most important systems for the safety in driving vehicles, and therefore driver assistance system has gained much attention during the last decade. This paper proposed an intelligent driver assistance system which monitors human driver's states from bio-signals such as ECG and Blood Pressure. The proposed system used mamdani fuzzy inference to evaluate the driver's mental strain and generated warning signals to the driver. The approach using bio-signals in driver assistance system is the main issue of the related systems and the preliminary results showed the possibility of further research topics in developing more intelligent embedded systems with bio-signal feedback.

텔레매틱스 정보단말기는 가독성, 시인성, 주행 안전성의 사용성과 HMI(Human Machine Interface)를 고려하여 설계해야 한다. 텔레매틱스 정보단말기 GUI을 구성하는 요소로 Menu Type, Menu Structure, Font Size 등이 있다. 그러나 한글이라는 지역적 특성에 대한 연구가 미흡한 상태이다. 따라서 본 연구에서 국내 운전자를 대상으로 텔레매틱스 정보단말기 GUI Factor에 대해 국내의 환경에 맞는 설계를 도출하였다. 피험자는 총 30명(남자 24명과 여자6명)을 대상으로 가상 주행 시스템을 이용한 시뮬레이션 환경에 Task를 수행하도록 하여 실험을 하였다. 분석은 ANOVA, 다원배치법, T-test, Font 일반식 대입을 통해 이루어졌다. Menu Type은 가로세로 2*3 배열의 형태와 버튼간 간격을 주행안전성 및 시인성에서 고려하여 설계해야 한다. Menu Structure는 3Depth가 3Frame 보다 주행안전성 및 시인성이 5%유의수준에서 더 우수하다고 나타났다. 운전자 안구 거리에 따른 Font Size를 도출하는 일반식은 어두운 글자인 경우 0.0069radian * d = Font Size 가 되고, 밝은 글자인 경우 0.0075radian * d = Font Size 가 된다. 위와 같이 본 연구는 GUI 세가지 항목에 대하여 국내 운전자의 사용성과 텔레매틱스 정보단말기 간의 인터페이스를 고려하여 기존의 시스템에 대하여 에러를 줄이고, 수행능력을 향상 시켜 주었다.

Traditional tactile controls that include push buttons and rotary switches may cause significant visual and biomechanical distractions if they are located away from the driver's line of sight and hand position, for example, on the central console. Gestural controls, as an alternative to traditional controls, are natural and can reduce visual distractions; however, their types and numbers are limited and have no feedback. To overcome the problems, a driver interface combining gestures and visual feedback with a head-up display has been proposed recently. In this paper, we investigated the effect of this type of interface in terms of driving performance measures. Human-in-the-loop experiments were conducted using a driving simulator with the traditional tactile and the new gesture-based interfaces. The experimental results showed that the new interface caused less visual distractions, better gap control between ego and target vehicles, and better recognition of road conditions comparing to the traditional one.

The man-machine interface Is an important factor in the computer system, and it is thought that line-of-sight (LOS) detection technology will allow significant advances in this field. Techniques for detecting LOS for use in human interfaces have been studied［1]［2］. In earlier studies, however, LOS was detected with a head piece, goggles, or through fixing the position of the head. The limitations imposed by these fixed conditions render them unsuitable far use in interfaces, as they have adverse mental or physical effects on humans. Therefore. they have not been sufficiently developed for practical application. Research on non-contact LOS detection is expected to result in a usable LOS man-machine interface［3］［4］, and the current study is intended to be a step in that direction. The authors used color contact lenses for LOS detection, and applied this new method to a computer interface. The use of color contact lenses simplifies image processing. The algorithm used in this study is sufficiently accurate for practical applications. This technique can be used in input devices, in virtual reality applications, and in human engineering research.

Recently, the automotive technology has developed with electronics and information technology as convergence technology while vehicles had been regarded as machines. Moreover, vehicles are becoming more intelligent and safer devices, assembly of advanced technologies by customers' demand. Even though all of installations of vehicle have attracted as diverting devices, it cause drivers' mistakes like delay of response on traffic condition. Here, we proposed the Field Operational Test (FOT) environment which could be used as driving and road conditions collector(Vehicle motion, Traffic condition, Driver input, Driver state, etc.) for researches about Driver Friendly Intelligent System(SCC, LDWS, etc.), Human Vehicle Interface(Driving Workload, etc.) and Economic Drive Model. Furthermore driving patten and fuel consumption patten of drivers were analyzed by measured data and direction of future research was suggested.

The phenomenal rate of growth of the design, implementation and use of interactive computer-based systems has been paralleled by an appreciation of the criticality of the human factor with regard to successful systems operation. As the pace of technological innovation quickens, and the design of user interfaces involves more complex interaction techniques, user frustration, confusion, degraded human performance, and an unwillingness on the part of users In perform interaction tasks were potential outcomes. Consequently, the important of user-centered interfaces design and use is increasing. Usability-based systems improve user acceptance and satisfaction with the systems

사용자인터페이스는 다양한 학제의 결합에 의하여 생겨났다. 이는 장점일 수도 있으나, 어느 한 학문분야의 특성과 고유성을 제대로 반영하고 있지 못하는 단점도 가질 수 있다. 따라서 연구의 목적은 디자인 영역의 특수성과 고유성을 반영한 사용자인터페이스 체계를 개발하여야하는 당위성과 개발하여야 할 때에 필요로 되는 요소 및 관점을 찾는데 있다. 이를 위하여 사용자인터페이스의 개념을 인간과 대상 그리고 관계의 기술 형식과 그 의미를 살펴보고 디자인과 비교를 통하여 유사성과 차이를 규명하였다. 또한 사용자 인터페이스가 디자인 영역에 도입되게 된 배경을 살펴보고 그 원인을 분석함으로써, 디자인과 사용자 인터페이스와의 관계를 고찰하였다. 결론으로는 사용자 인터페이스는 디자인의 광범위한 의미에 포함될 수 있는 개념과 체계이나 아직 디자인의 특성에 적합한 체계로서 발전되지 않은 상태라는 것을 알았으며, 이를 위하여서는 개념의 해석, 개발프로세스 등에서 디자인의 특성을 고려한 개념과 방법, 지식의 개발이 필요하다는 것을 알 수 있었다.

CNS (Car Navigation System) is the most compatible candidate among various in-vehicle information systems as a provider of ITS (Intelligence Transport Systems) information. It generally consists of remote controller, display, CD-changer, GPS receiver and so on. Among them, display is the most important and critical element of the HMI (Human-Machine Interface) suggesting the digital map to the driver. Therefore, it is certain that the display gives cognitive, physical, mental and visual workloads to the driver which are directly related with the driver's and road safety with the success of ITS. Until now, various human factors techniques have been developed and applied to estimate the driver's workload and to collect the driver's requirements of the CNS digital map, for example, mental workload assessment, visual activity analysis, cognitive analysis and so on. In addition to these kinds of techniques, this research performed the human sensibility ergonomics approach to directly investigate and evaluate the driver's requirements and sensibilities of the real products.
