In this paper we introduce a quiz application program that digitizes the analogue quiz game. We digitize the quiz components such as quiz proceeding, participants recognition, problem presentation, volunteer recognition who raises his hand first, answer judgement, score addition, winner decision, etc, which are manually performed in the normal quiz game. For automation, we obtained the depth images from the kinect camera which comes into the spotlight recently, so that we located the quiz participants and recognized the user-friendly defined gestures. Analyzing the depth distribution, we detected and segmented the upper body parts and located the hands' areas. Also, we extracted hand features and designed the decision function that classified the hand pose into palm, fist or else, so that a participant can select the example that he wants among presented examples. The implemented quiz application program was tested in real time and showed very satisfactory gesture recognition results.

This paper introduce a quiz game contents based on gesture interface. We analyzed the off-line quiz games, extracted its presiding components, and digitalized them so that the proposed game contents is able to substitute for the off-line quiz games. We used the Kinect camera to obtain the depth images and performed the preprocessing including vertical human segmentation, head detection and tracking and hand detection, and gesture recognition for hand-up, hand vertical movement, fist shape, pass and fist-and-attraction. Especially, we defined the interface gestures designed as a metaphor for natural gestures in real world so that users are able to feel abstract concept of movement, selection and confirmation tangibly. Compared to our previous work, we added the card compensation process for completeness, improved the vertical hand movement and the fist shape recognition methods for the example selection and presented an organized test to measure the recognition performance. The implemented quiz application program was tested in real time and showed very satisfactory gesture recognition results.

The established Web Based Learning System had not encouraged Multi-Learner Interaction. The System for Multi-Learner Interaction proposed an alternative measure. By now, this System for Multi-Learner Interaction have applied the sphere of Web Based Learning. But, Actually, the Multi-Learner's Interaction and Feedback of this System has a few effective and confidence, because this System has much time gap between Interaction and Feedback of Multi-Learner primarily. This Research propose an answer of this Problem, Web Based Real Time Quiz-game Type Learning System for Multi-Learner Interaction. Moreover, this System expect increased concentration ability for Learning and strong motivation of Learning for the greatest Learning effects in a Subject Solution course of Learners with founding Web Based Quiz-game Type Learning. So this Research will design and implement the Web Based Real Time Quiz-game Type Learning System for Multi-Learner Interaction.

고성능의 인터넷과 컴퓨터의 보급은 Online Game이 개발 될 수 있는 기반을 만들었다. 또한 게임에 관련된 프로나 채널이 생길 정도의 많은 관심은 Online 게임이 급성장을 이루는데 많이 도움을 주었다. 그러나 많은 Online 게임 사용자는 서버 접속률과 진행 속도 저하의 원인된다. 그래서 접속한 많은 Client를 효과적으로 다를 수 있도록 각 게임마다의 각 특성에 맞는 Game Server의 구현을 필요로 한다. 이 논문에서는 그것의 한 방법으로 여러 개의 그룹별로 게임을 하는데 효과적인 서버를 연결 리스트와 multi-thread를 이용하여 구현하였다. Client를 효과적으로 관리하기 위하여 각 데이터를 연결 리스트로 연결하고 multi-thread 사용하여 클라이언트의 요청을 처리하였다.

Recently, various media such as broadcasting, movies, and mobile converge with game elements, expanding the contents and expanding the area. This study focuses on the gamification convergence contents. Among them, we examine the case of mobile application live quiz show by applying the formal elements of the game mentioned by Tracy Fullerton. The elements have all the formal elements of the game, which led to the conclusion that they lead the audience to immersion based on the play characteristics of the game. This can be attributed to the elements of the game that have penetrated into the contents, and it can be reinterpreted, and the directions of new contents can be presented, which is industrially, culturally and academically significant. This study focuses on the industrial and cultural achievements created by contents, and plans and prospects new content that balances play and usefulness.

Nowadays, we can easily find student who study through computer in e-teaming environment. But, although e-teaming system has strong point that overcomes limitation of distance and time, many students give up their study through on-line learning. In this study, we developed On-Line learning motivation model, and designed and developed on-line quiz game loaming system. Thus we can find student's teaming motivation was grow up through student's interaction. Also, we find on-line quif game learning system had many information that explain student's status about their knowledge.
