  • 최근 인간과 컴퓨터간의 원활한 상호작용의 필요성이 커짐에 따라 인간의 행동을 분석하는 연구가 많이 수행되고 있다. 기존의 시스템은 인간과 컴퓨터의 상호작용을 위해 3차원 센서 등의 별도의 장치를 필요로 한다. 그러나, 이러한 시스템은 원활한 상호작용이라는 관점에서 볼 때 자연스럽지 못하게 되고, 또한 시스템의 제약이 많기 때문에 다양한 시스템으로의 응용이 어려워지게 된다. 본 논문에서는 보다 자연스러운 인간과 컴퓨터의 상호작용을 위해서 센서가 아닌 카메라를 이용하여 대상을 입력받고, 이를 분석함으로써 대상이어떠한 상태이고, 어떤 동작을 취하고 있는지를 파악하여, 보다 자연스러운 인간과 컴퓨터간의 인터페이스를 구현하고자 한다.

  • In this paper, an effective method to detect the laser pointer on the screen using the neural network algorithm for implementing the human-computer interaction system. The proposed neural network algorithm is used to train the patches without a laser pointer from the input camera images, the trained neural network then generates output values for an input patch from a camera image. If a small variation is perceived in the input camera image, amplify the small variations and detect the laser pointer spot in the camera image. The proposed system consists of a laser pointer, low-price web-camera and image processing program and has a detection capability of laser spot even if the background of computer monitor has a similar color with the laser pointer spot. Therefore, the proposed technique will be contributed to improve the performance of human-computer interaction system.

  • The focus of this study was to investigate whether flow occurs during both goal-directed and experiential activities, if experiential and foal-directed flow states differ in terms of various measures and dimensions. Fifty male and eighteen female subjects were participated in controlled, comparative experiment between goal-directed and experiential activities in problem-solving tasks. The findings indicate that subjects experience more curiosity and involvement(focus) in problem solving tasks with experiential activities. However, the results showed subjects experience more enjoyment in tasks with goal-directed activities. Findings of this study suggested that more sophisticated and quantitative measures in various dimensions should be constructed and verified in order to apply flow theory to human-computer interaction.

  • 인간과 컴퓨터의 상호작용에서 사용성 (usability)은 사용 의도 (usage intention)를 결정짓는 중요한 요소로 주목을 받아 왔다. 하지만 최근에는 사용 의도 (usage intention)를 결정짓는 새로운 요소로서 재미 (fun to use)가 주목을 받고 있으며, 'Funology'라는 새로운 개념도 제시되었다. 재미에 대한 다양한 연구가 진행되고 있지만, 기존 연구들은 재미가 무엇인지는 여전히 명확히 정의하지 못하고 다른 감정들과 차이점을 살펴보거나 재미를 유발하는 몇몇 요소들을 제시하는데 그치고 있다. 따라서 본 연구에는 재미란 무엇인지 정의를 내리고, 사용자들이 재미를 느끼는 요소들에 대해서 살펴보고자 한다.

  • For many years, the approach taken towards HCI(Human Computer Interaction) has focused on the usability of system and technology. Advances in computing and information technology has shifted the way people use and experience technology from merely using it to enjoying using it. But, there is a lack of theories to conceptualize fun and user fun experience, in the HCI. This paper describes an conceptual approach to "fun" and user's 'fun experience' in the interaction of technology. This paper defines "fun" as positive psychological energy which is produced by playing computer. And this paper provides characteristics of 'Fun experience', which are action mode, random order, free, and activated pleasant. This study provides insights into factors contributing to and influencing fun experiences and the relationships between them; symbol, newness, and vividness.

  • This study deals with the issue of actual HCI design embodiment through the investigation on how to interpret and use visual expression means in HCI design in a semantic way. The purpose of this study is to provide the method by which designers can make the user-centered guidelines in HCI design. As a part of the user\ulcornercentered design approaches, this study is based on the understanding of user group types which are divided by his/her extent of exposure to computer especially and is focussed on applying the level of each group's apprehension of visual expression means to the embodiment of HCI design. Major findings of this study are: First, it proposes the 'Visual Tokens Models' as a basic source for the understanding and the embodiment of visual expression means in HCI design; Second, it has examined the correlations between the characteristics of Visual Tokens and user group types that is, naive users, casual users, and expert users; Third, it proposes guidelines for the user-centered embodiment of HCI design in accordance with the correlations.
