This study presents the analysis results through the experiments how to increase the user participation via the user created game contents(UCGC) which user oneself can produce in a game. The experiment was carried out for whether the three elements of self-express desire, providing game money, and competitiveness can increase active participation in UCGC by using a mobile game called 'Color Pop'. Through this, we summarized the comparative results of the importance and influence for the three elements. It is expected that it will be used to improve understanding of UCGC users and plan or produce UCGC.

Recently, game companies are having difficulties in exactly figuring out the right consumer groups for their games. To solve this problem, a system algorithm which recommends user-customized games based on the user information entered has been proposed in this study. Game developers will be able to clearly determine the consumer group(s) of both on and off-line games through accumulated data while consumers can find the game they desire. It is expected that the gaming culture will advance further with the proposed algorithm.

In games, immersion is the most important factor that makes the player play game continuously. The user's inability to immerse in game makes him/her not interested in game, so it makes the user give up. So, we must perceive the immersion factor that the games have. By applying the factors that causes immersion to the game development, we will be able to multiply the joy of game to the user, and bring high profit to the game developing enterprises. To this, this study finds out the interrelations between the factor of immersion existing inside the game and the components of the game to experience the highest immersion status to the user.

This study is to observe the correlation between user properties and user behavior on the mobile game, one of the most prominent digital contents with the most mutual interaction. Among various factors affecting on behaviors of game users, the user properties itself was accentuated, and the effect of individual and psychological quality on the use of game was evaluated. The user properties were mainly categorized into five factors of "interpersonal relationship", "level of game skill", "inclination of innovation", "self-esteem", and "competitive spirit", and the use behavior of game was categorized mainly into two types - quantitative behavior of "amount of use (time of use, consumption cost)" and qualitative behavior of "perceived satisfaction level (perceived enjoyment, perceived service quality, and perceived price)". As a result of study, in general, as the user quality subjected in this study is stronger, the amount of use and satisfaction level are higher. This study is to observe what type of user qualities leads to the more use, consumption, and satisfaction level of game contents to contribute to the study about the use of conventional digital contents and heavy use.

Computer games should keep user's immersion for fun. Flow can be occured on the balance of user's game skill level and the difficulty level of the challenges by an immersion theory. Computer games can make automatic control of the challenge difficulty level but user's game skill makes difficult to know instantly its level on gameplay because the skill is decided by game goals, user tendency, or user experience. In this paper, we proposed a method of measurement of user's gameplay skill level that we can know the skill level instantly on gameplay. The proposed methods require to be implemented in the stages of the design and implementation of the computer game to be used. Computer games can keep continuously the balance of user's game skill level and the difficulty level of the challenges in order to occur flow immersion by using the proposed measurement method and automatic control methods of the difficulty of game challenges.

As a software component for computer game, the physics engine simulates objects' movement according to the laws of physics. This paper introduces a design and implementation of mobile game on the Android platform, where we used JBox2D physics engine library and Android graphics APIs. We borrowed the key idea of this game from Crayon Physics which is known as a famous PC game. This game starts with no way from user character to destination character. The game user has to make a way to destination character from user character by creating polygon objects between them. The user wins when user character meets destination character. However, the game user has to decide the time to create objects and their shapes well because all objects in this game are governed by the laws of physics. As an important thing of this paper, we introduced into this game new input methods of LCD touch and sensors embedded in mobile devices but not in PCs. Game users can create objects by drawing polygons with LCD touch and move objects or characters according to sensor values from accelerator sensors by tilting the mobile device.

Among the various security threats in online games, the use of game bots is the most serious problem. In this paper, we propose a framework for user behavior analysis for bot detection in online games. Specifically, we focus on party play that reflects the social activities of gamers: In a Massively Multi-user Online Role Playing Game (MMORPG), party play log includes a distinguished information that can classify game users under normal-user and abnormal-user. That is because the bot users' main activities target on the acquisition of cyber assets. Through a statistical analysis of user behaviors in game activity logs, we establish the threshold levels of the activities that allow us to identify game bots. Also, we build a knowledge base of detection rules based on this statistical analysis. We apply these rule reasoner to the sixth most popular online game in the world. As a result, we can detect game bot users with a high accuracy rate of 95.92%.

Domestic game industry is growing around game contents service. Game contents service is becoming popular because it has character that can use a game with opposing user on network in real time and advantage that can download the wanted game at anytime or anywhere. It is different to general service from the view point of user. In order words, the user of game contents service has different character from that of general service because their using characteristics in service using effect are shown use variously in the demographics, psychology and behavioral particular. In these views, we have done a comparative analysis character between game contents service and general service.

This study attempted to identify differences in user experience and app game fun, satisfaction, use intention between fitness app games at different level of interaction design. The playtesting method was conducted on 100(male 50, female 50) university students using 'Enjoy Your Fitness', a fitness app game developed by The Center for Health Communication Studies. The results found that more interactive app game is higher in the level of user experience such as fitness accomplishment, flow, and interest. Fitness app game's fun, satisfaction, use intention is also higher on interactive fitness app game. As the study verified that interactive fitness app game had stronger effects in user fitness experience and user experience than general fitness app games through experimental studies, it may contribute to design fitness mobile app game for health improvement.
