Do cultural differences affect moral decisions? Two studies were conducted to investigate whether attitudes of individualism vs. collectivism have an impact on ethical decision making. Study 1 (N=92) showed that utilitarianism was preferred in a situation, in which an intervention resulted in the best outcome (i.e., saving more people's lives), while deontology was preferred in a situation, in which the focus was on negative consequences of the intervention (i.e. personal sacrifices). Additionally, there were differences between the idiocentrics and the allocentrics groups regarding morality aspects. In the idiocentrics group, harm and fairness were regarded as more important than other moral aspects, while in the allocentrics group, not only harm and fairness, but also ingroup and authority were perceived as critical moral aspects. In Study 2 (N=30), after lexical decision tasks were conducted for culture priming, the mouse tracking method was used to explore response dynamics of moral decision processes, while judging appropriateness of interventions in moral dilemmas. In Study 2, in a condition, in which the small number of victims were focused upon, there were more maximal deviations and higher X_flips in the individualism priming group than in the collectivism priming group, which showed that the participants in the individualism condition had more deliberative processes before choosing their answers between utilitarianism and deontology. In addition, the participants in the individualism priming condition showed more maximal deviations in the mouse trajectories regarding ingroup related interventions in moral dilemmas than those in the collectivism priming condition. These results implicated the possibilities that the automatic emotional process and the controlled deliberative process in moral decision making might interact with cultural dispositions of the individuals and the focus of situations.

Purpose: Developing a calculating program for the prism power which influenced the binocular vision according to shifts of binocular visual points in the distance vision spectacles. Methods: By using the Delphi 6.0 programming language, we developed a calculating program of the relative binocular prism power according to the movements of binocular visual points in the distance vision spectacles, which was calculated by dragging the mouse along the traces of binocular visual points on the computer window. Results: We developed a calculating program for the relative binocular prism power according to the movements of binocular visual points in the distance vision spectacles. The user of the program could confirm the trace of visual points by allowing them to display the trace of binocular visual points on the computer screen with a mouse button. An application on confirming the variation of prism power by graphs in the program also allowed the user to use the program more conveniently. Conclusions: By using the developed program, the user could easily calculate the relative binocular prism power according to shifts of binocular visual points in the distance vision spectacles. We also found that the developed program helped the user to receive a lot of assistance in analyzing the asthenopia.

본 연구는 기존의 프레젠터의 단순한 포인터 및 클릭 기능을 넘어선 다기능 제스처 인식 포인터의 구현이 주 목적이다. 주된 연구 내용으로는 적외선 발광 다이오드에서 나오는 빛을 인지하여 포인터의 궤적 인식을 하는 기술과 이를 응용한 어플리케이션의 개발에 있다. 본 하드웨어에는 기본적인 마우스 클릭 기능 외에도 적외선 발광 다이오드를 탑재하여 PC와 연결된 카메라가 이를 인지하도록 한다. 장점으로는 카메라가 항상 PC와 가까이 있을 필요가 없으므로 어느 장소이든 관계없이 적외선 투과 필터가 장착된 카메라 하나만 설치할 수 있는 곳이면 구현이 가능하며 적외선을 이용하므로 가시광선의 영향을 적게 받아 효율적으로 영상 처리를 할 수 있다는 데에 있다. 제스처 인식을 통하여 수많은 여러 가지 기능을 실행할 수 있으며, 보다 사용자와 인터랙티브한 작업이 가능해진다. 구현된 하드웨어와 소프트웨어 시스템은 프레젠테이션 및 게임 컨트롤에 사용되었다.

The purpose of this study is to provide a cost effective usability test model for business web site development. In this study, we present a usability test model that combines Concurrent Think Aloud, performance measurement, coaching method, and remote test method. Testing target was the consortium website of electronic information joint licensing. Test participants were actual users selected by their task roles and proficiency in different levels. We improved the system by reflecting the results of user test analysis and re-tested usability test again. The result showed that usability of all participants was improved in the aspect of the time required and the complexity of mouse trajectory. It is expected that the usability test model presented in this study can be used to cost-effectively evaluate and analyze business web sites. We suggest that research various usability test model considering the characteristics of websites.

This paper proposes Visual Script Language which can direct a type of motion to 3D human model and create by dragging gesture like as we can express a certain meaning with hand gestures. Traditional motion control technique of articulated figures such as human needs a complex task that draws on highly developed human skills. So it will reduce the amount of motion specification to provide the motion control method that allow users to describe characters' motion at the higher level abstraction. Visual script is the visual gestures to direct various human motions, so users can express the spatial attributes of a motion such as the path of moving with high-level concepts if they use visual script. And we can show that it is possible to control the motion of human model directly and intuitively by development of 3D human motion control system based on visual script.

Our research was performed in order to implement a new pointing device for human-computer interactions in a collaborative environments based on Tiled Display system. We mainly focused on tracking the position of an infrared light source and applying our system to various areas. More than simple functionality of mouse clicking and pointing, we developed a device that could be used to help people communicate better with the computer. The strong point of our system is that it could be implemented in any place where a camera can be installed. Due to the fact that this system processes only infrared light, computational overhead for LED recognition was very low. Furthermore, by analyzing user's movement, various actions are expected to be performed with more convenience. This system was tested for presentation and game control.
