The mobile content which adopts the subject matter of wired online game with interoperability element is in service. This is one of the plans which are the possibility of benefiting wired online game in game industry. In this paper, interoperability method of game content between wired and wireless classifies this with three branches and it tries to analyze the interrelationship of the interoperability element and interoperability types adopted in many wired online games. And, the development of interoperability server is composed of mobile server which takes charge of I/O process of mobile device and game server records all information of users in the game. With developing the content which is suitable in specific game(Ran-Online), this paper presents the development method of game content through interoperability between wired and wireless.

In this paper, we developed the device for an interactive game interface using bio signals which were able to recognize user's motion intention using EMG signals and it was applied to the games which need the information of the muscle motion directions. The module for acquiring EMG signals consists of 4-Ch, wrist-motions were defined as up, right, down and left state. The user's intent was recognized through thresholding and comparing signals of each channel. The classification result of the motion directions could control the arrow keys on the keyboard of PC and it was applied on the various games. This proposed game device can be expected to induce an effective exercise with an interesting and enjoyment, and it can use both self-developed or commercial games.

The success of Nintendo's Wii has changed the paradigm of console game. Existing games and consoles set up the game-playing system of complicated commands, narratives, and significantly advanced the degree of difficulty by the device's excellent capacity and the superiority of graphic in order to draw so called "Game Manias", while Nintendo established the easy game-playing system for not only game manias but women and elderly people. Such an innovation has carried out the most important role for Nintendo to dominate the market all over the world by 47.4% market share of consoles. In addition, it provided the users with unique interaction and emotional experience. In this study, we analyze the case above in terms of product design strategy, particularly emotional design strategy between Nintendo & Sony.

In this paper, we present a new game interface design for First Person Shooters (FPS). Previously, FPSs on computer are commonly played using keyboard/mouse or joystick along with PC display. We improve the communication environment between player and game world by means of new control system including large screen, laser gun, and directional device, which create a real life-like space for players. Because traditional display for FPS uses CRT, it cannot support large screen display due to limitation of CRT technology. We designed and implemented a new input device using laser recognizable display. We implemented a new FPS based on Quake III that is in accordance with the new devices. Results suggest that the combined interface creates a method which helps beginners to enjoy playing a FPS immediately and gives experienced players a new gaming experience.

Recently, interest in game streaming is high in cloud-based gaming. In game streaming, remote game servers perform graphics rendering and stream the resulting scene images to clients' device on the Internet. We model the client-server allocation (CSA) problem for balancing the GPU load between servers in a game streaming environment as an optimization problem, and propose a simulated annealing-based method. The features of our method are that the method takes into account the constraints on network delay and has the ability to automatically adjust the frame rate of game sessions if necessary.

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.

This research aims to investigate the difference between game graphics which considers key elements and game systems which do them in the rating classification of adult arcade games during reviews. The case of the supreme court about 'The Golden Porker Castle' last year for 3 years presents the basis whether considers the game graphics or the game system during the review for the game. It implies to identify the gambling game device for the adult arcade game. This research try to find the direction for the scientific, systematic rating classification to enhance the reliability and the validity in it.

This paper researched the possibility of applying FMEA that estimates and eliminates the failure modes into the measurement of tangible game's safety. Tangible game with actuation makes unexpected accidents for the game users. And this article tried to give risk priority number to 2 categories, game device and physical injuries using FMEA method. The result showed that TV and Hand laceration and/or bruise were revealed as the most risky factors among the others. In conclusion, it is suggested that FMEA can present integrated, quantitative and coherent measurement for the safety of tangible game.

Recently, as one method of the game manipulation, physical interactive game is increasing, which controls the program by direct human movement. Tangible interface for physical interactive game implementation can control virtual model directly through real world object. A digital desk, one of the tangible interface, offers the interface that human can manipulate virtual object directly, by making projection screen on real world desk as computer display device. In this paper, we implement "Battle Region" game in the form of tangible interface, which can offer game users an efficient and amusing experiences by the use of physical interactive game. Traditional game cannot pursuit the diversity of game background contents but our game can do it through Map image projection. From this, game provider can supply the diversity of choice and users ran set up the difficulty of game. Therefore, our implemented game can offer users an efficient and amusing experiences by making game user's challenge and satisfaction maximum.

Virtual Reality (VR) is becoming a new standard in the game industry. PokeMon GO is a representative example of VR technology. The day after the launch of PokeMon Go in the U.S, It has achieved the highest number of iOS App Store downloads. This is an example of the power of VR. VR comprises gyroscopes, acceleration, tactile sensors, and so on. This allow users could be immersed in the game. As new technologies emerge, new and different threats are created. So we need to research the security of VR technology and game system. In this paper, we conduct a threat analysis for information assurance of VR device (Oculus Rift) and game system (Quake). We systematically analyze the threats (STRIDE, attack library, and attack tree). We propose security measures through DREAD. In addition, we use Visual Code Grepper (VCG) tool to find out logic errors and vulnerable functions in source code, and propose a method to solve them.
