사용자 및 기기의 상황을 파악하고 이에 따라 실시간으로 사용자 인터페이스를 변경하는 '적응형 사용자 인터페이스 (Adaptive User Interface)' 연구가 진행되어 왔다. 기존 관련 연구들은 주로 설계 방법론에 초점을 맞추고 있으며, 요구공학 방법론에 대해서는 거의 다루어지지 않았다. 본 연구에서는 적응형 사용자 인터페이스를 요구공학 관점에서 조명하고, 자가 적응 시스템 분야에서 연구되어 온 개념들에 기초한 요구사항 도출 및 명세 방법을 제안한다. 잘 알려진 자가 적응 소프트웨어 개념들을 재정의 및 해석한 후, 적응형 사용자 인터페이스 요구사항을 도출 및 명세하는 방법을 단계적으로 보인다. 사례연구에서는 제안하는 방법에 따라 적응형 사용자 인터페이스 요구사항을 도출 및 명세하여 본 기법이 효과적임을 보인다.

Objective: The objective of this research is to investigate the fundamentals of human computer interaction for wearable computers and derive technology requirements. Background: A wearable computer can be worn anytime with the support of unrestricted communications and a variety of services which provide maximum capability of information use. Key challenges in developing such wearable computers are the level of comfort that users do not feel what they wear, and easy and intuitive user interface. The research presented in this paper examines user interfaces for wearable computers. Method: In this research, we have classified the wearable user interface technologies and analyzed the advantages and disadvantages from the user's point of view. Based on this analysis, we issued a user interface technology to conduct research and development for commercialization. Results: Technology requirements are drawn to make wearable computers commercialized. Conclusion: The user interface technology for wearable system must start from the understanding of the ergonomic aspects of the end user, because users wear the system on their body. Developers do not try to develop a state-of-the-art technology without the requirement analysis of the end users. If people do not use the technology, it can't survive in the market. Currently, there is no dominant wearable user interface in the world. So, this area might try a new challenge for the technology beyond the traditional interface paradigm through various approaches and attempts. Application: The findings in this study are expected to be used for designing user interface for wearable systems, such as digital clothes and fashion apparel.

Realization of the economical, reliable, and efficient ATM interface block becomes an important key to development of the ATM switching system when we consider new issues raised recently. In this paper, we summarize requirements for the ATM interface block and present the UNI (User Network Interface)/NNI (Network Node Interface) architecture to meet these requirements. We also evaluate the performance of the multiplexer adopting the various multiplexing schemes and service disciplines. For ATM UNI/NNI interface technologies, we have developed a new policing device using the priority encoding scheme. It can reduce the decision time for policing significantly. We have also designed a new spacer that can space out the clumped cell stream almost perfectly. This algorithm guarantees more than 99 % conformance to the negotiated peak cell rate. Finally, we propose the interface architecture for accommodation of the ABR (Available Bit Rate) transfer capability. The proposed structure that performs virtual source and virtual destination functions as well as a switch algorithm can efficiently accommodate the ABR service.

This paper deals with the design and the development of user interface for a high speed linear programming solving system. The general users' educational and practical requirements are analyzed and the functionalities that should be implemented for the requirements are designed. The user interface of the system consists of various carefully designed built-in commands that perform the functionalities. The names of the build-in commands are chosen to enhance the users' convenience. We also address the various factors that should be considered in the design of the linear programming solvers when integrated with the user interface. As one of user-friendly environments, data input system that can understand user-written arithmetic form is added to our user interface system. Finally, we compare our system with other user interface systems.

In this paper, we provide safety requirements and advices to guarantee the safety of an interface in a level crossing system which is an interface between the conventional facilities and the new ATP (Automatic Train Protection) system, as well as we accomplish a safety management for the facilities of a country that has a different standard with already standardized ATP system. The system model has been made based on a safety activity of the international standard, and then a tolerance of a risk by the safety activity through PHA (Preliminary Hazard Analysis) has been analyzed. finally we achieved HIA (Hazard Identification and Analysis) for the assumptions that have been produced from a operating scenario and a functional interface. Thus, the safety requirements for the interface has been provided from the safety plan of HIA, and we showed the safety activity to guarantee the system safety through HIA which was depend on the design.

The use of unmanned combat systems is of interest for future battlefield. Advanced techniques are being actively studied to build fully autonomous unmanned systems. However, there are technical, ethical and legal limitations for the fully autonomous unmanned combat systems. In addition, a remote controlled system is necessary so far in order to prepare for situations where fully autonomous unmanned systems fail to function properly. Thus, a procedure of developing operational requirements in system level is proposed and interface requirements of unmanned combat vehicles for remote control are described in this study.

In this paper, we proposed a smart lighting management system controls the lighting efficiently to reduce energy consumption while satisfying user's lighting requirements. The proposed system considers the available daylight intensity and indoor light source to satisfy the lighting requirements of each user according to the work environment. In addition, for user convenience, we have developed different user interfaces for lighting control including local interface, and remote interface through internet or Bluetooth for personal computer as well as smart phones. The proposed system satisfies the lighting requirements of each user according to the corresponding work environment. The proposed smart lighting management system utilizes the lighting energy efficiently, and can be considered a significant contribution towards future green buildings.
