This paper empirically studies R&D investment and firm value in game companies. Found the following results First, the empirical results show that negative relation between R&D investment absolute scale and firm value. On the other hand, an increase in R&D intensity has simultaneously positive relations with firm value. On an existing research, we can conjecture that game companies should increase its R&D intensity rather than R&D investment absolute. Couldn´t find significant results when it comes to long term performance of R&D. In light of these, can be inferred that R&D investments affect more short term than long term firm value in game industry.

We present a palm recognition system that can be used for developing an interactive amusement including game contents. The first step of our system is to capture palm photographs using web camera and to extract hand region using YCbCr color transformation and the active contour model. In the second, we build a template that formulates the conditions for recognizing palm lines. We apply Hough transform to the hand region to extract line information and match the extracted lines with the template to recognize palm lines. We further build a series of fortunetelling stories that match the shape and organization of palm lines to complete the amusement system based on palm recognition.

Digital dementia becomes an issue these days which causes failure of one’s memory and calculation ability because many people rely heavily on digital devices, such as smart phones. Smart devices themselves become smarter and smarter whereas digital device users become dumber and dumber, and finally they are suffering from digital dementia. Serious games can be defined as games which combine entertainments with various applications. They relieve the negative opinions which belong to existing games, so many game titles have been released as serious games in these days. This research is motivated by the fact that serious games were originated to overcome practical issues. In this paper, a serious game is presented to prevent digital dementia and its effectiveness is shown. The proposed serious game is composed of simple four fundamental arithmetic operations which improve one’s calculation ability. Since simple arithmetic operations are familiar regardless of one’s age, they are chosen. Everyone can enjoy the game beause random factors are added. This paper concludes that serious games can be used to prevent digital dementia very effectively.

In this paper, we present a technique for applying artistic effects to videos based on a pencil rendering technique. First of all, we propose a vectorized line generation method as a primary technique for solving temporal coherence problem which appears when applying some artistic effects to video. In addition, we propose progressive pencil rendering technique which controls detailed range of drawings from rough sketch to detailed drawing for video. Also, regarding that a real color pencil has a limited set of colors, we suggest limited color pencil rendering method. Furthermore we analyze hand drawing pencil drawings, compare them with rendering results and complement some weakness. A series of our works has a meaning of not only technological but also aesthetical consideration for pencil drawings.

People have been experiencing lot of incidents for their lives which results in gaining their impetus. Each impetus derives an emotion and such emotion is either of positive or negative one. The positive emotion motivates activation of his life but the negative emotion demotivates one. Specifically, the negative motivation will be much worse for children and it could be adversely affected to their emotional development. The paper first characterizes how to regulate an emotion in a view of psychology base and also characterizes how to regulate the emotion for children. And then, we analyze serious game contents which have been developed to care a negative emotion for children and youth to derive some game elements to be used in the games. Finally, by combining the two characterizations of regulation of emotion in psychology view and the serious games, we propose effective game elements for caring children’s negative emotion. We expect that the results will provide a good guideline when we make a serious game to care children’s negative emotion.

The 2013 Korean Gaming White Paper suggested that the mobile gaming market has a potential for the future value realization. The market of mobile games exploded by 89.1% compared to 2011 and the market share almost doubled. With higher infiltration and performance enhancement of the mobile devices, accompanied by the growth in the mobile advertisement market, fueled the development of the relevant infrastructure and the business model, which is the basis of our anticipation on the gaming industry to grow further. Unlike the weight it carries in our society, the literatures in the field of mobile games are scarce, which is why we conducted this study. In this study, we will focus on the characterizing factors of the mobile game and their relationship with immersion in order to identify with proofs the intent of their users for continued, repeated usage of the mobile games using statistical methods. The purpose of this study is to identify the characterizing factors of the mobile games that affect the intent for repeated usage and immersion, with a view to contribute to the development of the mobile games and the mobile gaming industry. The result of the evidentiary analysis revealed that the internal and external factors of the mobile games did have positive impacts on immersion into them, and the immersion into the game positively affected the intent for repeated usage. In addition, we examined the differences between genders in terms of the influence from the characterizing factors onto immersion, which revealed statistically significant differences between the genders and was reflected in our consideration on the implication of this study.

The purpose of this research was to explore whether playing self-hygiene serious game has any effect on the knowledge, self-efficacy, and behavior related to self-hygiene of young children. Three children, ages 5 and 6, all male, participated in this study. Three children were observed for one, two, and three weeks before game play. After this baseline period, the children were given a game titled Parasite Wars, in which the children have to kill the parasites to get healthy, to play for one week. After the initial exposure to the game, the children were observed during one week of game play for self-hygiene behavior. Also, immediately before and after the week of game-play, children were tested on knowledge and self-efficacy related to self-hygiene. Results indicate that all children improved in knowledge and self-efficacy after the gameplay. Numbers of voluntary hand-wash increased after initial exposure to the game for all three children. The numbers of verbal facilitation for hand-wash all decreased with game-play.

It is needed to try to make good games that exert a good influence on game users. This paper proposes the new game design of a Bible Smart Phone Game for Sunday school. To support this idea, the play system of popular running games is used for fun, and players are quizzed about sunday school lesson for education. Also, we made a game prototype of this Bible Game in android platform.

Gamification is a new concept using elements of game mechanism with clear goals in non-game contexts. This idea has been used successfully in a variety of domains with positive effects of games and game culture. As games have been a powerful tool in persuasion and behavior changes with purposive desings, such gaming effects have brought about a new era, called “Game 3.0”. This paper proposes transitional aspects of Game 3.0 Era, by focusing on gamification concepts and applied game machanism. From previous literature, the structural elements of gamification can be derived from the concepts of play, entertainment game, edutainment, funware, and serious games. Likewise, core elements of gamification comprise participation & engagement (as motivational factors associated with digital games, GameFlow, E-GameFlow), game mechanics, and game dynamics. The various aspects of game eras from Game 1.0 to Game 3.0 are summarized and discussed.

This study is to develop a mathematical analysis model to grasp the behaviors of cartels. Cartels are formed tacitly and cause tremendous damage to consumers in modern society which is composed of advanced industry structure. The government authorities have instituted the leniency programs to respond cartels. However, cartels will continue unless there are legal sanctions against cartels based on an accurate analysis of leniency programs. The proposed cartel equilibrium analysis model is a mathematical behavior model which is based on the existing methods and the prison’s dilemma of game theory. Therefore, the model has a form of pay off matrix of two players. We use a iterated polymatrix approximation (IPA) method to deduct a Nash equilibrium point. The model is validated by an empirical analysis as well.

This Study has analyzed the trends of flow studies in the domestic game field. First, the flow studies in the domestic game field are mainly from economics, business administration, journalism and broadcasting and so on. Second, the content of studies is biased toward the use of games. Third, the definition of the flow concept is divided into the following two methods. The one is the method of describing user's flow condition and the other is the method of describing antecedents and consequence of flow. Fourth, technology acceptance model is mostly introduced as a theory associated with flow. The loyalty is mostly presented as a dependent variable of positive results of flow experience. Our study analyzed former studies on flow theory which is useful to research user's immersion and continuous use of games. We expect that the results of the study will be useful data for domestic game industry, research and so on.

In this paper we offered a new UI design for Chinese input method on smart devices during Gameplay. Currently the well-known conventional stroke-based Chinese input method using only five basic stroke types could achieve low leaning curve and small keypad implementation, we made the UI design base on this stroke-based input method compensating the problem that input speed is limited and finally relatively higher the input speed. For experiment we designed and implemented the new UI for input method by Unity3D. Input by pressing or typing keys is replaced by more using sliding. To improve the input speed of the stroke-based method slide direction arrows are used and selected character will be intuitively shown to user in real time as designed. And the Four Tones(四声) in Chinese pronunciation is also been used to improve the input speed for this input method. In addition, to evaluation the new input method UI, we have conducted experiments on smart device comparing with four basic Chinese input methods. Through the numeric values recorded in the evaluation by inputting random 20 Chinese characters and two-letter Chinese words, comparing the input speed, click times, the typo rate shows the advantages of the new UI and proved that the new UI is better than others for using in smart device game.

We present an improved sketch-based image search technique through which users can search their target images from the images in database. This technique can be used in constructing an efficient game development framework. Our basic approach is to search the database by comparing the user-created sketch with the graph extracted from the images in the database and estimating the similarity. The images of high similarities are suggested as the candidates that match the target image. To improve the accuracy of the matching process, we substitute the graph-based representation of images with vectorized coherent lines, which are known as one of the most precise schemes in extracting and describing important features in an image. By the experiments on 820 images of 32 categories, we prove that our scheme shows higher matching accuracy than the existing schemes.

This paper proposes an educational smartphone applicaiton which usages augmented reality and GPS on a smartphone to lead a learner's experience, and which provides games on cultural properties to keep the learner's interests.

Multi-view system is one of the auto-stereoscopic displays that allows users to watch 3D images without wearing special glasses. Generating contents for the multi-view display system is often accomplished using Depth-image-based rendering (DIBR) intermediate view generation. DIBR-based intermediate view generation method reconstructs a 3D scene with a color image and depth map information. Then, a virtual camera is put in various view positions to capture intermediate view images. In this research, we tried to improve the quality of the DIBR-based intermediate views by applying non-uniform quantization method for depth map information. This paper describes the intermediate view generation process using DIBR. Then, it discusses the evaluation of multi-view intermediate images generated using uniform and non-uniform depth quantization methods. Finally, the paper describes the future direction and how the muti-view systems can be utilized in computer games.

We present a Microsoft Kinect-based hand recognition algorithm for an interactive image clipping system, which is widely used for environments such as public facilities and security environments where personal capturing devices including mobile phones are not allowed. User-friendly interface and accurate image capturing function are required for an image clipping system. We build the system by combining Microsoft Kinect, HD webcam and projector. The Kinect and webcam are used to capture the motions of users' hand and project is to display the user-selected area from the capturing material. Hand recognition is composed of three steps: (i) the region occupied by users' hand is extracted from an image, (ii) the fingertips of the extracted hand region are analyzed using k-curvature algorithm, and (iii) the height of the fingertip is estimated using the depth image from Kinect. The height of the fingertip informs whether users' finger touched the surface of the target. The region captured by the fingertip is clipped from the image and stored as the target image. The excellence of our hand recognition algorithm is proved through a user test.
