The market of digital avatar with internet and digital technology is increasing rapidly. The users want to express any free-formed motion of their avatars in the cyber space. The user s motion capturing method as the avatar's motion can express any free-formed motion of the avatar in real-time but the methods are expensive and inconvenient. In this paper, we proposed a new method of expressing any free-formed motion of the avatar in real-time. The proposed method is an algorithm for real-time control of a 3D avatar in symmetry-formed free motion. Specially, the algorithm aims at the motion control of a 3D avatar for online dancing games. The proposed algorithm uses the skeleton character model and controls any one of two hands of the character model by a joystick with two sticks. In the symmetry-formed motion, the position and orientation of one hand can determine the position and orientation of the other hand. And the position and orientation of a hand as an end-effector can determine the pose of the arm by Inverse Kinematics. So the algorithm can control the symmetry-formed free motions of two arms by one joystick with two sticks. In the dance game, the algorithm controls the arm motion by the joystick and the other motion by the motion captured DB.

In this paper, we implemented online real time strategy game using hand as the mouse in augmented reality. Also, we introduced the algorithm for detecting hand direction, finding fingertip of the index finger and counting the number of fingers for interaction between users and the virtual objects. The proposed method increases the reality of the game by combining the real world and the virtual objects. Retinex algorithm is used to remove the effect of illumination change. The implementation of the virtual reality in the online environment enables to extend the applicability of the proposed method to the areas such as online education, remote medical treatment, and mobile interactive games.

On-line game industry had accomplished much growths and development. One in pain of the game enterprises according to quality of on-line comes to be short Game production pipeline and it is suitable in quick production schedule and to be easy to the standard research of form by of 3D game character animations which are various the game production at the time of application is possible, operation by and type by in necessity. Element by model classification of the digital base game character which is used in game it set from the research which it sees and research it analyzed and the fundamental data which is necessary to 3D game character animation productions escape it tried. And the digital motioncapture it applies a cap department system and real picture of the character animation which is various at real-time the control research moving and it advances at the time when the effectiveness is short highly in game industry and digital contents industry application the character animation production process which is possible and production pipeline escape the reporter to do it does.

There have been many trials for development of games using augmented reality. This paper presents a 2D puzzle game system using HSV color space to detect hand posture from an input image by smart device's cameras in real time. The developed game in this paper brings smart devices and the computer vision closer. Also this game can be a new interactive technology utilizing both the mobility of smart devices and the tangible interactivity of virtual reality in education and entertainment environments.

Currently, there are many augmented reality content, but little has been commercialized that two or more terminals communicate in real time and use at the same time. In this paper, we are going to study the possibility of network augmented reality contents using Bluetooth communication. Through this research, network augmented reality development and contents will be expanded further.

Generally, the animation and image production process consists of three stages: Pre-Production, Main-Production, and Post-Production. Real-time video production is also made based on this configuration. On the premise of the increase of productivity by reducing the production time effectively in the main production stage that takes the most time, this study aims to summarize the process of producing videos, focusing on the concrete main production stage. To do this, we propose a method for creating a real-time image from the point of view of the general user using Unity 3D, one of the game engines. Also, this study utilizes the Cinemachine feature provided by Unity 3D, which is suitable for the implementation of the proposed module structure.

Multiplayer, real-time games are a kind of soft real-time systems because a game server has to respond to requests from many clients within specified time constraints. Client events have different timeliness and consistency requirements according to their nature in the game world. These requirements lead to different priorities on CPU processing. Events can be divided into different groups, depending on their consistency degree and priority. To handle these events with different priority and meet their timing constraints, we propose a priority-based group task scheduling policy in this paper. The number of clients or events requested by each client may be increased temporarily. In the presence of transient overloading, the game server needs to allocate more CPU bandwidth to serve an event with the higher priority level preferentially. The proposed scheduling policy is capable of enhancing real-time performance of the entire system by maximizing the number of events with higher priority completed successfully within their deadlines. The performance of this policy is evaluated through extensive simulation experiments.

A key challenge in massively multiplayer on-line game(MMOG) systems is providing real-time response latencies to the large number of concurrent game players. MMOG systems are a kind of soft real-time systems because requests from many players should be responded within specified time constraints. Client events have different timeliness and consistency requirements according to their nature in the game world. These requirements lead to tasks with different priorities on CPU processing. In order to meet their timing constraints, we propose priority scheduling methods that attempt to allocate preferentially more CPU bandwidth to serve an task with the higher priority level in the presence of transient overloading. The proposed scheduling methods are capable of enhancing real-time performance of MMOG system by maximizing the number of tasks with higher priority completed successfully within their deadlines while minimizing total average latency of tasks finished after given deadlines. The performance of these scheduling methods is evaluated through extensive simulation experiments.

In this paper, we propose a game server using public network library ACE, which has been developed in various fields for a long time. ACE network library has been considered not only in the area of high efficient real-time communication library but also in the area of application development, and it provides various facilities. We logically reorganized the part, which is necessary to develop games, among various functions of ACE and optimized it, and developed real battlenet server using verify the reorganized library. As the method of experiment, the battlenet server and test client were set and interface request test and data electrical transmission test were conducted. As the result of the experiment, the conclusion that it is possible to develop games by using ACE, which is verified network library, has been obtained.

In this paper we tried to figure out the types of real money trade of game items, and in order to study it we examined the Leveling System of MMORPG which is a perfect competitive market and how the closed structure of the game economy emits real money trade. The over production of the MMORPG's leveling system which is a perfect competitive market increases the amount of currency in circulation and then induces arbitrage due to mudfalation inside the game. In order to improve this problem, there are three methods of resolutions. The first is stabling the game economy by spontaneous order among the game users, but this is much local than the artificial order which takes a long time and evokes discrepance in MMORPG competitive characteristic. Secondly, legislational regulations from the government could improve the problem, but this method doesn't grant information or services as non-material labor in which it couldn't follow up the developing speed of the game market. Finally, delicate modulation among game items by the designer isn't possible to constrain them, and there is a limited reason that it couldn't control the increase of currency which is the main factor of arbitrage.
