For the 3D game visual effects, the deferred rendering can only consider only the scene image resolution regardless of the scene complexity. Therefore, it is effective in processing realistic visual effects using many geometric buffers as multiple render targets. This paper uses the deferred rendering for the 3D game visual effects such as dynamic lights, specular, shadow, motion blur, and water shading. The 3D game supporting deferred rendering is developed to evaluate various 3D rendering effects with variation of the screen resolution in terms of the rendering speed and PSNR image quality. The performance results show that the rendering speed of the 3D visual effect techniques with 1280x960 resolution is average 56.0% better than that with 640x480 resolution. Also, the average PSNR is getting better as the screen resolution gets higher. The PSNR of the 3D visual effect techniques with 1152x864 resolution is average 30.9% better than that with 640x480 resolution.

This paper analyzes the simulation operation flow of Bullet physics engine. Based on this analysis, four kinds of multi-rigid-body game characters are designed. This paper also profiles the performance metrics such as the CPU utilization, the memory usage, and the computation time by multi-rigid-body character simulations. For the CPU utilization, the Tongs Vehicle is the best and provides 45.1% less than the other character simulations. The computation times of the Four-leg robot and the Dragon are longer than those of the others. The memory usage of the Dragon simulation is the largest, which is average 1.32 times more than the others. Because all parts of Dragon are composed of triangular mesh models in 3DMax. The performance profiling with the criteria such as reducing the computation time and the computing resources, the complexities of the collision shapes, and the number of rigid bodies takes an important role in the design of the multi-rigid-body game characters.

As a macroscopic research for the economic system in MMORPG’s, I have analyzed the differentiation & characteristic of each economic system such as Picking Economy, Laissez-faire, Revised Capitalism, Neo-liberalism as well as Economic Democracy which is shown on online game. The picking economy of online game, like as Ultima Online, has the characteristic of co-work & co-distribution but the capitalist who has accumulated wealth appeared on Laissez-faire period. When the economic system of Laissez-faire has fell down, Revised Capitalism that includes the characteristics of government intervention has appeared. Finally, ArcheAge and MapleStory 2, which are represent for Neo-liberalism and economic democracy, are characterized by recovery of market functions & welfare.

The genetic algorithm (GA), one of the artificial intelligence (AI), is developed based on Darwin's theory of evolution, i.e., the mating of randomly selected objects. If more optimal solution is generated, then it is better to repeat the process of setting the optimum value. In this paper, the method of background music using the genetic algorithm is exploited when the computer game is executed each time. As a result, it has created several music that can be used in the actual game, and it could be confirmed that the other music that is created is different music when performed each time.

In this paper, we propose a method to automatically generate a height map image that can be useful for creating 2.5D clip. To this end, we used a Viola - Jones algorithm that segments eyes, nose and mouth of the image and analyzed the characteristics of each to derive the height value that is used for producing a final height map . Finally, we can apply the height map to create photo-realistic images that can be easily reproduced for synthesizing 2.5D animation in Adobe. To verify the proposed method, we have carried out a user study between 2.5D movies clips which are proposed our automatic method and a manually generated method.

Recent studies have shown that during the playing of violent online games, it is not increased aggression but rather alleviation in aggression that is critical in determining whether playing gaming has positive outcomes on the venting of aggression. Drawing from the aggression catharsis perspective and gaming research, we extend this line of investigation by exploring whether gaming results in a decrease in aggression, across a wide variety of games. Using data from a survey of 771 online game users in Korea, we examined the associations among Therapeutic Catharsis Seeking, Game Self-Efficacy, Big Five Personality Traits, Game genre (violent or nonviolent), Daily online gaming time, and Demographic variables. Results showed that therapeutic catharsis seeking and game self-efficacy decreased user aggression. Neuroticism negatively affected aggression while agreeableness enhanced the degree of aggression regardless of game genre. These findings have important implications for the use of gaming as a mood management tool.

Action recognition technology has many application fields including gaming, human-computer interaction, security, virtual reality, etc. The technology has recently advanced and simplified by the introduction of real time depth cameras. The most famous depth camera, Kinect, has shown its success in human action recognitions by supervised learning methods. However, those method require a large number of motion capture data as the ground truth of each skeleton points. This paper proposes a human skeleton extraction method without using reference data. The method extracts the minimum number of articulation points instead of full skeleton data. The articulation points are used as an real-time interface for 3D interaction games.

As mobile devices are becoming ubiquitous, more users encompassing different are groups are enjoying mobile games. There are two types of mobile games – games mandating a certain type of learning and games not requiring any sophisticated learning such as casual games. In this paper, we first define th the degree of learning and compare the acceptance of these two types of mobile games on two different ages groups, i.e., 2~30 age group and 40~50 age group. For this experiment, we recruited 20 users, 10 users per each group, and each participant responds to our survey after playing 15 games with different degrees of difficulty. Our survey results show that 1) both age groups are more engaged in popular games, 2) 20~50 age group is less engaged in brain-teasing games and social network games, 3) both age groups feel difficult as more learning is required, and 4) 20~30 age group quickly learns new games if those are similar to the games they played before.

It is important matter to develop game that game designs should consider improving game development, especially work schedules. We hardly ever see the game design documents, because almost all game development is privileged information, not to be shared with the general public. So many developers put a lot of work in. If the time is saved by modularization of game design documents. This paper focuses on discussion of the game planning method through making modularization of design documents. In order to achieve this purpose, first, find out the consist of games. Second, extract common game design elements and considerations. It can help for game developers who start game planning or design for the first time, also it can be reduced time needed for design documents.
