Recently, HTML5 have drawn many people's attention since it is considered as a next-generation web standard and can implement a lot of graphic and multimedia-related techniques on a web browser without installing programs separately. In this paper, we implement a game independent of platforms, such as iOS and Android, using the HTML5 canvas. In the game, the main character can move up, down, left, and right not to collide with neighboring enemies. If the character collides with an enemy, the HP (hit point) gauge bar reduces. On the other hand, if the character obtains heart items, the gauge bar increases. In the future, we will add various items to the game and will diversify its user interfaces by applying computer vision techniques such as various gesture recognition.

This study mainly focused on horror movies and horror games. Camera angles of horror movies and compositions of horror games are main factors that can cause fear in people's minds. Through analyzing four kinds of factors, including sensual, expectant, restrictive and executive fear elements, in horror games, and combining with the patterns of camera angles and film techniques that Alfred Hitchcock applied in his horror movies, this research investigated certain types of compositions and concluded ones that were more effective on growing fear in players' minds and enhancing their involvement. In conclusion, only the combination of factors in horror-game compositions, like diagonal composition, dual-diagonal composition and inverse triangle-line composition, with visual elements enables player's growing sense of fear and the increase in involvement. Therefore, future works should apply more of these fear-inducing compositions.

There have been many researches on the characteristics of item trade. However, most researches were done by carrying out a survey and there has been few researches by analyzing the economy in online games. So, this article studied the cause of item trade by looking into the supply and demand of items in online games. The results shows that item trade is taking place mostly among only a few number of gamers who enjoy enchanting and who engage in castle sieges and blood pledge battles. The proportion of item trade by general garners is not so big. And major item providers are gold farms, not garners. Therefore, item trade is mostly carried out by a large number of garners who trade a small amount of sum and by a small number of heavy garners who trade large amount of sum. Understanding this characteristic of item trade would be a good ground for reviewing the policies and social effect regarding item trades.

Recently, medical advances have been increasing the size of the aged population. With rapidly developing technology, computers are now essential parts in our daily life, and the number of the aged people using computers is also increasing continuously. But user interfaces and contents for the aged people have not yet been developed actively. In this paper, we present a 3D sensory gate-ball game which can be played by the aged people easily. This study is based on 3D graphics and uses a realistic gate-ball stick and balls as interfaces, so it can improve both physical and metal health of the aged people. Because our game is a sensory game, it is easy to play in house without an outdoor playground. In addition, the game provides many interesting situation so that it can raise the participation and interest of the aged people.

Generally, the existing Artificial Intelligence (AI) systems were designed for specific purposes and their capabilities handle only specific problems. Alternatively, Artificial General Intelligence can solve new problems as well as those that are already known. Recently, General Video Game Playing the game AI version of General Artificial Intelligence, has garnered a large amount of interest among Game Artificial Intelligence communities. Although video games are the sole concern, the design of a single AI that is capable of playing various video games is not an easy process. In this paper, we propose a GreedyUCB1 algorithm and rollout method that were formulated using the knowledge from a game analysis for the Monte-Carlo Tree Search game AI. An AI that used our method was ranked fourth at the GVG-AI (General Video Game-Artificial Intelligence) competition of the IEEE international conference of CIG (Computational Intelligence in Games) 2014.

The need of high quality VR contents has been steadily raised in recent years. Therefore, this study investigated the user's interest factors of VR game which is receiving the most attention among VR contents. We used STEAM review data and applied Text mining and Network analysis to perform this research. As a result, it was possible to confirm 4 word clusters related VR game users. Each cluster is named by 'presence', 'first person view game', 'auditory factor' and 'interaction'. This study has its meaning. First, user related research would be very helpful to develop high quality VR game. Second, it confirms that review data of VR game users can be structured, analyzed and used.

Advances in IT technologies are developing VR content technologies that provide five senses information to users and interact with them. These VR content technologies are widely used by users not only for time and space limitations but also for providing immersion experiences. VR contents are contents that allow users to experience images that are played on the screen through five senses such as augmented reality, virtual reality, and holograms as well as visuals. VR games are also becoming more diverse in interfaces for the interaction of users with VR games. This study recognized the importance of the interface and analyzed the impact of the application characteristics of VR game UI on user experience and satisfaction from the user perspective. Research shows that VR game UI interacts with user experience and satisfaction. This appears to affect user experience based on how well people using VR game UI can understand and utilize the characteristics and functions of UI.

In this study, models for predicting the final result of League of Legends game were constructed for each rank using data from the first 10 minutes of the game. Variable importance was extracted from the prediction models to derive strategic direction in early phase of the game. As a result, it was possible to predict final results with over 70% accuracy in all ranks. It was found that early game advantage tends to lead to the final win and this tendency appeared stronger as it goes to challenger ranks. Kill(death) was found to be the most influential factor for win, however, there were also variables whose importance rank changed according to rank. This indicates there is a difference in the strategic direction in the early stage of the game depending on the rank.

This research studies the behavior patterns of a character in FIFA Online3, and the transaction patterns between the characters to present a character that acts like a real person and has social interaction with other characters. A character interacts with others mediated by balls in FIFA Online3, we analysis character's behavior and interactions more cleary. Providing the realistic behavior patterns of a character and the relation in the transaction patterns between the characters based on psychology theory, we can give a player the sense of reality. To define the behavior pattern of a character, this study applied the Ego-state as defined by Transactional Analysis(TA). Based on the Transactions in TA, this study then defined the transaction patterns between the characters, which are produced by the actions that a character in the game. This study also presented how to apply a character's transaction patterns with the examples. It showed that a character can act in the game like a real person by defining how a character acts and interacts in the game.

This study is to reveal the meaning of the interaction between a player and a game with the approach of an operational interaction such as joystick and keyboard, and also a representational interaction that the player takes during the game. It has been usually recognized that cut-scene in existing games is just limited to the role of opening scene that delivers mainly a background story of the game, and has the only passive function that serves additionally the expression of the state of the player or the replay of the results of the player's action. But in the aspect of game-direction, the study of the player's action about the interaction movie of 'Uncharted2', for example, one of the most representative video games, shows the possible classification of interaction movie along with three functions(situation direction, induced selective-action, information transfer). As a result, it is judged that interaction movie is not an additional element for the game-play, but rather takes the function of as an interface. The effective application of interaction movie could help a smooth connection between the recognizability from the view point of the player and the playing from the main character's viewpoint, ultimately leading to a direct means to maximize the delivery of the story.
