오늘날 유비쿼터스 컴퓨팅 기술, 홈 네트워크, 스마트 홈 등의 연구 개발로 여러 기기들과 컴퓨터가 연동한다. 이에 따라, 다양한 기기에 맞춰 여러 가지 사용자 인터페이스가 필요하며 이를 위해 사용자 인터페이스를 여러 번 개발해야 하는 비효율적인 일이 빈번하다. 또한, 개발자에게 있어서 여러 기기에 사용되는 서로 다른 언어를 모두 익히고 개발하는 것 역시 많은 부담을 준다. 이러한 문제를 해결하기 위해 UIML(User Interlace Markup Language)이란 마크업 언어가 제시되었다. 그러나 UIML도 여러 언어로의 변환을 위해 각각의 다른 변환 모듈을 이용해야 하는 번거로움이 있다. 본 연구에서는 다중 기기로의 사용자 인터페이스 변환과 상황인식이 가능한 마크업 언어인 HIML(Human Interaction Markup Language)을 제안하고 통합된 사용자 인터페이스 변환의 모델을 스마트 홈 환경에 적용해 보았다.

If a virtual object in a virtual environment represented by a stereo vision system could be touched by a user with some tactile feeling on his/her fingertip, the sense of reality would be heightened. To create a visual impression as if the user were directly pointing to a desired point on a virtual object with his/her own finger, we need to align virtual space coordinates and physical space coordinates. Also, if there is no tactile feeling when the user touches a virtual object, the virtual object would seem to be a ghost. Therefore, a haptic interface device is required to give some tactile sensation to the user. We have constructed such a human-computer interaction system in the form of a simple virtual reality game using a stereo vision system, a vibro-tactile device module, and two position/orientation sensors.

최근 차량 내부와 외부 교통환경으로부터 운전자에게 다양한 다량의 정보가 제공되고 있다. 이와 같은 정보가 범람하는 교통환경에서 운전자가 안전하게 운전하기 위해서는 운전자에게 '필요한 정보'가 '적절한 시기'에, '쉽게 지각할 수 있는 형태'로 제공되어 '올바른 판단'을 할 수 있도록 해야 한다. 이를 인간-자동차 인터랙션(HVI: Human-Vehicle Interaction) 기술이라 할 수 있으며, 진정한 의미 의미에서의 HVI 기술이 이루어지기 위해서는 운전자가 운전을 함에 있어 사용하고 있는 자원에 대한 관리, 즉 운전부하 관리가 기반이 되어야 한다. 따라서 본고에서 운전자의 운전부하 관리에 대한 정의와 기술개발 동향을 살펴보고자 한다.

This paper proposes a novel human-computer interaction system for the disabled using recognition of face direction. Face direction is recognized by comparing positions of center of gravity between face region and facial features such as eyes and eyebrows. The face region is first selected by using color information, and then the facial features are extracted by applying a separation filter to the face region. The process speed for recognition of face direction is 6.57frame/sec with a success rate of 92.9% without any special hardware for image processing. We implement human-computer interaction system using screen menu, and show a validity of the proposed method from experimental results.

A human-friendly interactive system, based on the harmonious symbiotic coexistence of humans and robots, is explored. Based on this interactive technology paradigm, a robotic cane is designed to help blind or visually impaired travelers to navigate safely and quickly among obstacles and other hazards faced by blind pedestrians. We outline a set of the hardware solutions and working methodologies that can be used for successfully implementing and extending the interactive technology to complex environments, robots, and humans. The issues discussed include the interaction of human and robot, design issue of robotic cane, hardware requirements for efficient human-robot interaction.

Polysaccharides have attracted great attention for their wide range of applications in biological and medical fields. In this paper, the interaction of polysaccharides with human serum albumin (HSA) was systematically investigated by fluorescence (FL) spectroscopy and circular dichroism (CD) spectra under different conditions. The Stern-Volmer quenching constants ($K_a$) at different ionic strength and pH were calculated, and information of the structural features of HSA was discussed. FL and CD results indicate that both hydrophobic and electrostatic interactions play important roles during the binding process. The quenching of the fluorescence resulting the binding of polysaccharides and HSA is static.

In this paper, we developed not only a reliable sound localization system including a VAD(Voice Activity Detection) component using three microphones but also a face tracking system using a vision camera. Moreover, we proposed a way to integrate three systems in the human-robot interaction to compensate errors in the localization of a speaker and to reject unnecessary speech or noise signals entering from undesired directions effectively. For the purpose of verifying our system's performances, we installed the proposed audio-visual system in a prototype robot, called IROBAA(Intelligent ROBot for Active Audition), and demonstrated how to integrate the audio-visual system.

In recent decades, focuses on usability and emphases on user-centric design have become more prevalent in the field of software design. However, it is not always easy for engineers and computer scientists to think in the users' shoes. Human-computer interaction (HCI) is a field of study that focuses on creating technologies easier and more intuitive for the users. This paper is based on teaching HCI skills to undergraduate computer science students in a software application design course. Specifically, this paper employs: first, the HCI skills taught to the students; second, the tendencies and challenges of the students in creating user-centric applications; and lastly, suggestions based on our findings to promote HCI in developing user-friendly software. While more firm conclusions shall be reserved for more formal empirical studies, the findings in this paper still offer implications and suggestions for promoting user-centric approach for software designers and developers in the technology industry.
