Nowadays users of Virtual Environment are want to play with thousands of players in an evolving virtual world at the same time over the internet. So, the load of this kind of Virtual Environments is heavier than that of any other precedents. One of load balancing methods is map-partition to divide the load of entire system which is vulnerable to delay message between clients and servers. In this paper, we propose a Migration Agent application server architecture using to help migration of player character between field servers and to reduce response time between clients and field servers. Migration Agent is reduce Player Character's responds time as Cache Server, if Player Character move to another Field Server, Player Character need the synchronization process in the DBMS approach, to minimize response time by reducing the period for cross - Player Character Field Server to perform the role. Field Server by placing them in form of a stack existing form of grid, for load concentrated on a specific server.

A player character has a significant influence on immersion. In order to understand the consumers, it is necessary to compare age and gender of player characters, which is the most basic feature of the player character. We selected a prize winning work of 15 years of USA and japanese as research subjects(in RPG and Adventure), classified age and gender of player characters and analyzed the result. In the japanese games, the ratio of pre-set player characters was 94.3% for age and 88.6% for gender. In the USA games, It was the order of the pre-set character which did not specify the age and the customized type character. In this research, we would like to contribute guidelines for player character setting to successfully advance into the USA and Japanese game market.

This paper aims to study whether the perspective of the character controlled by a player can affect the player on her moral decision. To this end we designed and developed Castaway, an interactive story using Unity3D game engine. The main story plot of Castaway is based on the trial 'R v Dudley and Stephens (also known as mignonette 1884) which occurred at 1884 in U.K. In Castaway, the player can choose either the accused or the victim, and then play the interactive story with the perspective of the chosen character. To investigate the relationship between the player's empathy to the player character and player's moral decision, we conducted a small-scale (n=10) pilot study. Results of the pilot study have shown that different perspectives can influence the player on her empathy to player character and her moral decision. In near future we plan to conduct a main study with more participants.

From several commercialized games the technique of changing facial expressions is imported, and a design method of a game character for the player's empathy is expected to be diversified in the future. In this paper, as a design method of a game character for the player's empathy, this makes walking motion for the game character applied with 'human-emotion' factors as statistics variation of a game character in RPG genre. After this paper implements analyzed emotions of human facial expression and walking motions applied with emotion in examples of character animation theory, this paper divides walking motion applied with human-emotion factors into 8 types through relationship to statistics factors in RPG genre. And then these are applied to a knight character, which has the most similarity with human's physical feature of the game characters in RPG genre, and makes walking motion as variable statistics. As a game player controls the game character applied with 'human-emotion' factors, the effect of the player's empathy about the game character becomes higher, and the level of immersion in game play is also expected to increase.

The non-player character(NPC) either cooperates with the player character to proceed the game or fight against the game player. This paper proposes the context awareness method for the natural action control of the same NPC. The context awareness method analyzes the context information of the NPC that can be utilized in the current status and creates the actions which suit the current context automatically. The context awareness method analyzes the information value of the context elements of the NPC which occur in the current context and creates natural actions of the character by utilizing the analyzed context element information. In this experiment, average performance improved by 39% and by 8% in the context awareness method as compared to the rule-based method and information gain method, respectively.

In football simulation games, it is very important for the interest of the game to make the stats of the football players close to reality. As the management concept is introduced to the sports simulation game, when the user plays the game for a long time, the existing player character retires. Therefore, the game creates the environment of the game by creating a new player in the game. In this study, we propose a method to create a new player character by using genetic algorithm to have the optimal ability similar to existing players. We compare and evaluate the player character with the existing random generation method, the correction random method and the proposed algorithm, and verify the validity of the proposed method.

포괄적인 개념에서, 게임에서 인공지능이란 PC(Player Character, 사용자에 의해서 조정되는 게임 오브젝트)를 제외한 모든 것들을 제어하기 위해 사용되는 일련의 기술이라고 정의할 수 있다. 예를 들면, PC를 둘러싸고 있는 환경, PC를 대적하거나 경쟁관계에 있는 NPC(Non-Player Character), PC에 조언을 해주는 조언자 NPC 등을 제어하고 사용자가 느끼기에 지능적이면서 실제적인 것으로 보이도록 하여 게임의 흥미를 더하기 위한 기술들이다. (중략)

Recently AI(Artificial Intelligence) is one of the issues in the on-line game, a research that a game character seems to be realistic and is progressing using AI technique. Especially NPC is an important part of the AI researches of on-line game, and it is concerned by a game player and an architect. We proposed an intelligent agent framework to implement the NPC technique after studying the NPC technique using context awareness that reacts to the PC(Player Character) actively. Also, it can be developed gradually, and apply to various application because it has the capability to of adding an agent or deleting an agent easily.

The character is one of most important interest-element in role playing game genres since it shows the individuality. In general cases, game players allocate points to talent clauses that they choose. However, it is not easy to provide the suitable character-growing to players in generic system since the cases are too simple and based on just humans choices. In this paper, we propose the character growing system based on the player type inference module. Growth morphology is determined by player's behavior or type. The determination is based on petri-net. Our experimental results and analysis show that our proposed approach is suitable for character-growing system.

In this paper, we have proposed to show the change of player character's status visually in character graphics. We have chosen strength and dexterity as basic character status out of strength, constitution, willness, intelligence, and dexterity to express the transition of character graphics. The length of each bone can be reflecting the numerical value of dexterity, and the thickness can show that of strength. This kind of visual representation of character status helps player to reveal his/her character identity. We are expecting this visual representation for direction of fostering characters and character's experience would be applied to various entertainment areas widely.
