본 논문은 항상 지니고 있는 스마트폰으로 노트북 사용자가 마우스를 휴대해야 하는 불편함을 해결하기 위해 이를 대체할 수 있는 안드로이드용 스마트폰 마우스 어플리케이션을 설계하였다. 우리는 기존의 다른 연구나 실제 이미 출시된 마우스 어플리케이션들과 달리, 블루투스를 이용하여 인터넷을 사용할 수 없는 상황에서도 작동하도록 하였으며 터치패드가 아닌 가속도 센서를 통해 실제 마우스처럼 동작을 인식하도록 하였다. 또한, 스마트폰 어플리케이션의 장점인 추가적인 기능을 쉽게 추가할 수 있다는 점을 살려서 진동 모드, 자동 연사, dpi 조절 기능 등을 포함한 게이머 마우스로 설계하였다. 정확한 마우스 포인터의 이동을 표현하기 위해 운동방정식으로 센서값을 속도로 바꿔서 이를 사용하였다. 그리고 센서 오차로 인한 오류 막기 위해 센서값을 필터링하였다.

With the deployment of web-based educational game over the internet, the user's registration becomes a critical element. The user is authenticated by the system using username, password, and unique code. However, it cannot be handled properly because the data is transmitted through insecure channel on the network. Hence, security requirement is needed to avoid identity leakage from malicious user. In this paper, we propose a secure communication approach using SSL protocol for an online game. We also describe the security requirements for our approach. In future work, we intend to configure and implement the SSL protocol by enabling HTTPS in web-based online game.

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.

Non-functional requirements plays a critical role in designing variety of applications domain ranges from safety-critical systems to simple gaming applications. Performance is one of the crucial non-functional requirement, especially in control and safety systems, that validates the design. System risk can be quantified as a product of probability of system failure and severity of its impact. In this paper, we devise a technique to do the performance analysis of safety critical and control systems and to estimate performance based risk factor. The technique elaborates Petri nets to estimate performability to ensure system dependability requirements. We illustrate the technique on a case study of Nuclear Power Plant system. The technique has been validated on 17 safety critical and control systems of Nuclear Power Plant.

At present, multiple input multiple output radars offer accurate target detection and better target parameter estimation with higher resolution in high-speed wireless communication systems. This study focuses primarily on power allocation to improve the performance of radars owing to the sparsity of targets in the spatial velocity domain. First, the radars are clustered using the kernel fuzzy C-means algorithm. Next, cooperative and noncooperative clusters are extracted based on the distance measured using the kernel fuzzy C-means algorithm. The power is allocated to cooperative clusters using the Pareto optimality particle swarm optimization algorithm. In addition, the Nash equilibrium particle swarm optimization algorithm is used for allocating power in the noncooperative clusters. The process of allocating power to cooperative and noncooperative clusters reduces the overall transmission power of the radars. In the experimental section, the proposed method obtained the power consumption of 0.014 to 0.0119 at K = 2, M = 3 and K = 2, M = 3, which is better compared to the existing methodologies-generalized Nash game and cooperative and noncooperative game theory.

The zombies in AVG games are not divided into different game occupations. To address this issue, this paper starts by selecting those popular zombie games as the research object. Then, a number of samples will be collected from the roles of zombie and these different roles of zombie will be classified by profession depending on the characteristics of these roles. On this basis, the roles will be given a new title to describe their profession. Then, semantic analysis will be conducted to search for the words that can be used to describe the roles of zombie. Besides, there will be 10 experts in design and 10 professional zombie game players invited to choose from the collected adjectives. The most selected words will be used in this study to conduct cognition assessment, before the making of questionnaire. Then, the questionnaire data will be collected and converted into a statistical model form for indicating the value of ability by group and profession.

This paper presents a new blockchain based donation platform combined with a type of gaming application. The proposed donation platform is similar to existing play-to-earn (P2E), but it has different characteristics such as non-liquidated token and direct transfer to a celebrity donation organization. Moreover, it has advantages like a robustness for counterfeiting and falsification as well as enhanced donating experience.

As the COVID-19 pandemic has decreased face-to-face communication in everyday life, our interest in cultural communication via virtual world has grown significantly. In particular, the demand for applications that use three-dimensional (3D) data generation technology such as virtual reality, augmented reality, virtual performances, and realistic content is rapidly increasing in the entertainment and gaming industries. Additionally, improved computing capacity has increased the demand for high-resolution data. This study investigates the trends in 3D scanning and photogrammetry technologies that can support high-quality 3D data generation and introduces the high-resolution 3D data generation technology developed and reported in ETRI.

Extended reality (XR) provides an immersive virtual experience by using various media. The XR virtual environment enables interactions between the real and virtual worlds in virtual, augmented, and mixed reality scenarios. XR is being used in various areas such as industry, medical care, road transportation, gaming, education, and culture. XR and multimedia enhancement are important business scenarios for fifth-generation (5G) mobile networks. As users' demand for emerging media services gradually increases, enhancements in networks should be implemented for delivering multimedia services such as XR. We describe related standardization trends and requirements of the XR service in 5G mobile networks. We also discuss technological enhancements for 5G mobile networks as specified by the 3GPP SA2 working group.

With the rapid adoption of 5G, the gaming industry has undergone significant innovation, with the quality of game content and player experience becoming the focal point of attention. ZBrush, as a professional digital sculpting software, plays a crucial role in the production of 3D game models. In this paper, we explore the application methods and techniques of ZBrush in game weapons production through specific case analyses. We provide a detailed analysis of two game weapon models, discussing the design and modeling process, lowto-high poly conversion, UV unwrapping and texture baking, material texture creation and optimization, and final rendering. By comparing the production process and analyzing the advantages and disadvantages of ZBrush, we establish a theoretical foundation for further design research and provide reference materials for game industry professionals, aiming to achieve higher quality and efficiency in 3D game model production.
