Motion based serious game is a new style of game and exercise using hands, arms, head and whole body. At that time gamer's reachable movement space is an important game space and interaction happening place. We propose efficient game spatial division and analysis algorithm that gives special information for collision avoidance of game objects. We devide into 9 parts of game space and check the enemy position and upper, down, left and right side movement information of gamer and calculate optimal path for collide avoidance of the enemy. To evaluate the method, we implemented a motion base serious game that consists of a web cam, a player, an enemy, and we obtained some valid results of our method for the collision avoidance. The resole demonstrated that the proposed approach is robust. If movement information is in front of enemy, then the enemy waits and finds the place and runs to avoid collision. This algorithm can be used basic development of level control and effective interaction method for motion based serious game.

As the prevalence of mobile platforms, expanding digital content production and also increasing interest about the serious game. However, existing educational serious games are short of application of educational function and lower effectiveness that not linked with off-line education. In this paper, we developed an educational serious game 'Rice-Mimi Adventure' for children based Tablet PC. The Games are designed five steps by four elements that storytelling, playing, music and cooking. Specially, players interaction between characters should be increase their own concentration and interest. For the effectiveness verification that linked education of on/off-line, experiment to 126 students of 3,4th grade in Choenan. A result shows positive data that on/off-line linked education using Tablet PC and effectiveness of game contents applied design factors. For this work, we should find effective class and teaching method using digital contents in off-line education for children.

During the past 10 years, serious game industry has been growing steadily. But the system which could stably and reliably provide metadata information and quality information related to serious game remained unexploited. Existing systems only support the basic management functions of metadata search centered. Therefore, we have developed an integrated system to manage the quality information of serious game as well as to improve the inconvenient details of the existing systems. And we designed quality evaluation elements and quality information supply-methods, and linked up them to the system. Furthermore, we conducted user's satisfaction assessment survey on the use of the system. The advantage of the system is that the system provide a lot of useful information for general users and developers, and support a tool to manage all information related to serious game by easy and convenient method for managers.

Recent national attention on English conversation continued, smartphone game has emerged into the mainstream of game industry. In this study, smartphone serious game that combines english conversation learning and smartphone game for learning english conversation was designed and implemented. English sentence patterns separated words, phrases, and sentences was able to learn step-by-step and repeatedly. Also, Throughout the game of different type by stage was to provide interested. Test results were discovered the problem not causing continuous user interest. To compensate for this, study of a game changes element and difficulty adjusting will be followed.

Emotion is very important feature in educational situation. Because it has high influence to memory, educational achievement, motivation. This study tried to find out possibility of serious game as emotional engagement tool in educational situation. We did our pilot experiment to elementary school students who are english as second language. In this L2 learning situation, we did our basic experiment with English language learning serious game called 'Word Collectrian". Word Collectrian has some features for emotional engagement. It has interaction for dynamic word visualization, providing context video for word usage, putting visualized word on learner's virtual home. According to experimental result, word Collectrian has possibility for educational achievement and emotional engagement effect.

The present study investigated the validity of a serious game named 'Draw Ttoring' developed for accessment of children's attention and tried to provide the basic information about it. To this goal, we tested it to 284 elementary school students in measuring various behavior data(reaction time, total playing time, correct rate, discrepancy between type of TMT). Futhermore, the behavior data was compared with academic achievement to see the external validity. In results, 'Draw Ttoring' showed various behavior data and correlation with academic achievement. In Type A of TMT, total time and reaction time had a correlation with academic achievement, while, in Type B of TMT, total time and correct rate did. Mental flexibility calculated by the discrepancy between Type A and Type B showed also the positive correlation with academic achievement. These results showed that the serious game named 'Draw Ttoring' can provide more various information about children attention and these can't be observed by traditional paper pencil test. Finally, serious game can provide an good alternative method to access children's cognition.

본 논문에서는 치매 등 인지기능 저하에 따른 질병을 예방하기 위한 기능성 퍼즐 게임을 설계하고 구현하였다. 치매 등 인지기능 저하에 따른 질병은 고령층에서 주로 나타난다. 이에 따라 게임의 UI와 규칙은 가급적 단순해야 하며, 동시에 기억력과 판단력, 반응속도는 향상시킬 수 있도록 해야 한다. 본 논문에서는 고령층에서도 쉽게 조작할 수 있도록 UI를 단순화시켰으며, 순간적인 인지능력과 단기기억력 및 판단력을 향상시킬 수 있는 색맞추기 퍼즐게임을 설계하고 구현하였다.

In this research, we investigated how interactive digital serious games could be used in traditional, offline, school classrooms. We asked four teachers from four different schools to use a job training serious game in their traditional job training curriculum and the teachers used the game in anyway they intended. As a result, the two main ways to integrate gaming into traditional curriculum were gaming within the curriculum and gaming outside the curriculum, although both methods were used to support the main curriculum. When the game was used outside the curriculum, teachers almost always had the students play the game during the computer lab class. Students also played games voluntarily during recess and at home. The factors that affected how the game was used were teacher, student, and location and accessibility of the computer.

This paper proposes a serious game for rehabilitation training targeting old persons and patients for rehabilitation. The serious game suggested for rehabilitation training provides the whole body movement recognition-based interface using the 3D depth camera. When the user stands before the camera, it distinguishes the user from the background and then recognizes the user's whole body with 15 joints. By analyzing the changes of location and direction of each joint, it recognizes gestures needed for the game. The game contents consist of the games for upper limb training, lower limb training, whole body training, and balance training, and it was realized in both 2D and 3D games. The system suggested in this article works robustly even with the environmental changes using the 3D depth camera. Even with no separate device, the game recognizes the gestures only using the whole body movement, and this enhances the effect of rehabilitation.

In this research, the effect of serious game on the task performance of adolescents with intellectual disabilities was investigated. A total of 31 students participated in a pre-post-with-control-group-design study. Results indicate that among the high-, moderate-, and low- ability students, the moderate-ability students gained the most from the game, in both speed and accuracy. From the results we can understand that game-based training has the most effect on the moderate level students. Also, the findings of this study show that serious games can be effective training tools for this population.
