As touch-screen mobile phones pour into the market, demands for reusing existing mobile game contents by adding a touch-screen interface are increasing. But, the contents which are developed in existing does not have touch-screen interface and in order not to be automatic is difficult with touch- screen contents to convert. From the present paper uses keyboard interface information about the mobile game contents which does not have touch-screen interface and creates touch-screen interface with automatic the method which proposes. This method analyzes the type of key events which are used from the contents the screen keyboard layout of optimum and construct. And, key event where is confronted with automatic occurs about touch screen event and creates the screen interface which executes the keyboard event handler. In the end, experiment leads and the screen interface which has become optimum anger to the contents creating, confirms.

In the prior works on tabletop systems, a projection-based tabletop surface is mostly used to display computer images, and the participants interact with the display surface by hand multi-touching or using some tangible objects. In this research, however, we developed the FishBowl game that employs a scalable tabletop tiled display with infrared camera tracking coupled with PDA mobile interfaces. The focus of this game is to enhance user interactivity and realistic experience by coupling the high-resolution tabletop virtual environment and PDA mobile interface. This paper describes the game design followed by the system design and its detailed implementations. It also discusses the system usability and recommendation for its improvements after interviewing game players and then concludes with future research directions.

Mobile game have an advantage of mobility, portability, and simple interface. These advantages are useful for gesture recognition based game which should not have much content quantity and complex interface. This paper suggests gesture recognition based mobile game content with user movement could be applied directly to the mobile game wherever recognition system is equipped. Gesture is recognized by obtaining user area in image from the depth image of TOF camera and going through SVM(Support Vectorn Machine) using EOH(Edge Of Histogram) features of user area. And we confirmed that gesture recognition can be utilized to user input of mobile game content. Proposed technique can be applied to a variety of content, but this paper shows a simple way of game contents which is consisted of moving and jumping newly.

The gesture classification has been applied to many fields. But it is not efficient in the environment for game interface with low specification devices such as mobile and tablet, In this paper, we propose a effective way for realistic game interface using k-nearest neighbors algorithm for gesture classification. It is time consuming by realtime rendering process in game interface. To reduce the process time while preserving the accuracy, a reconstruction method to minimize error between training and test data sets is also proposed. The experimental results show that the proposed method is better than the conventional methods in both accuracy and time.

In this paper, we propose a new framework to control VR(Virtual reality) contents in real time using user's mouth-wind and acceleration sensor of mobile device. In VR, user interaction technology is important, but various user interface methods is still lacking. Most of the interaction technologies are hand touch screen touch or motion recognition. We propose a new interface technology that can interact with VR contents in real time using user's mouth-wind method with acceleration sensor. The direction of the mouth-wind is determined using the angle and position between the user and the mobile device, and the control position is adjusted using the acceleration sensor of the mobile device. Noise included in the size of the mouth wind is refined using a simple average filter. In order to demonstrate the superiority of the proposed technology, we show the result of interacting with contents in game and simulation in real time by applying control position and mouth-wind external force to the game.

As a result of growth sensor-enabled mobile devices such as PDA, cellular phone and other computing devices, in recent years, users can utilize the diverse digital contents everywhere and anytime. However, the interfaces of mobile applications are often unnatural due to limited resources and miniaturized input/output. Especially, users may feel this problem in some applications such as the mobile game. Therefore, Novel interaction forms have been developed in order to complement the poor user interface of the mobile device and to increase the interest for the mobile game. In this paper, we describe the demonstration of the gesture and posture input supported by an accelerometer. The application example we created are AM-Fishing game on the mobile device that employs the accelerometer as the main interaction modality. The demos show the usability for the gesture and posture interaction.

The domestic game market is still on a trend of growth. Particularly, as the demand for mobile games is increased, the mobile version is developed in a growing number of cases even after the launch of the games for PCS. In a bid to search for the effective method of UI design depending on the differences between the platforms, this study analyzed the types of different media in the first place and as the approaches to the UI design based on the affordance concept, implemented on the platform of PCS and implemented on the platform of mobile devices were analyzed as the cases which are the same MMORPG games. Since the differences between the game platforms can cause the variations in the physical size of the screens depending on the environment in which the user interface (UI) is rendered and may often involve the controls implemented by the touch of screens rather than the manipulation based on the keyboard and mouse, they usually give the influences on the direction of UI designs. By analyzing these UI elements based on the affordance concept, it may be possible to find the effective method of UI design in the future.

The rapid development of the mobile internet has gradually changed the carrier of electronic games from PC to mobile. mobile games have become an excellent choice for many people to spend their spare time and enjoy life. Among many types of mobile games, Number of users of FPS games has increased rapidly in recent years. Based on the 《Emotional Design》 proposed by Donald Norman, this article compares the interaction design of China's most popular FPS game 《Game for peace》 and Korea's most popular FPS game 《PUBG》, and analyzes their similarities and differences, and then use that as a basis to summarize the three levels of emotional design-Visceral level, Behavior level, and Reflection level, which is the user interface, interaction mode, and interaction experience in interaction design Emotional expression on the two games. This theory provides suggestions for interactive design in the information industry such as mobile games.

Growing smartphone usage in South Korea has also accelerated the pace of development of mobile games, but competition is intensifying as the market grows. As one of the factors for the success of the game in this mobile game market, UI has been presented, suggesting that the design of such mobile game UI should be approached in terms of designing the user's experience, along with its function, aesthetic expression, function-oriented design and information delivery before. In this paper, we propose an effective lobby layout of mobile RPG using experience among UX factors. Through the layout classification of Ernest Adams and Andrew Rollings, we selected 9 mobile RPGs in the 20th place of google play cumulative sales rankings and analyzed the layout of the lobby. As a result, the lobby layout of the game, which led the first market success of the mobile RPG genre, The result was that it became the standard of the boxed game. It can be interpreted that the lobby layout, which is similar to the game used previously by the user, is effective because low entry barriers and learning are unnecessary due to the experience of using the existing RPG. Future studies may produce a common layout of a broad genre if studies are conducted to measure the optimum UX for other genres than RPG.
