The recording and matching method of pose and gesture based on PC-window platform is introduced in this paper. The method uses the gesture detection camera, Xtion which is for the Windows PC. To develop the method, the API is first developed which processes and compares the depth data, RGB image data, and skeleton data obtained using the camera. The pose matching method which selectively compares only valid joints is developed. For the gesture matching, the recognition method which can differentiate the wrong pose between poses is developed. The tool which records and tests the sample data to extract the specified pose and gesture is developed. 6 different pose and gesture were captured and tested. Pose was recognized 100% and gesture was recognized 99%, so the proposed method was validated.

Dementia once occurred is known to be mostly irreversible but can be treated only if it is detected early; especially vascular Dementia. Thus, in this paper we have developed Dementia diagnosis and care application through inter-working between biometric sensors and smart phone. With developing serious game for the demented elderly, we proposed ons-stop solution for Dementia; smart-phone application with diagnosis, prevention and mitigation of Dementia. Since the proposed game for mitigating Dementia requires sense of space and balance using both arms instead of operating simple arrow button, a treatment effect for Dementia will be doubled. If we tried to forestall, ease and cure Dementia with the proposed application. the social losses from Dementia would be minimized as a result.

Recent Software education topic is GUI programing language 'Scratch' and the open source computing platform plus microcontroller boards 'Arduino'. S4A means a program that controls the Arduino to the scratch. In this paper, development for education content that using S4A and combination the Arduino sensors. and we developed the game in the form of training content by using a variety of tools.

It is of great importance to categorize the genres of online games in order to get a useful conceptual framework. The reason for this is so that we can distinguish between the similarities and differences between the types of games. Most of researches, however, have not provided common criteria, other than subjective criteria or experiences. This paper finds the fundamental characteristic of games, that is, their interactivity and develops a conceptual framework including primary and corresponding participants, and controlling characters. Through an empirical research on World of Warcraft, this study shows that the framework is comprehensive covering all of interactivity at WoW and an useful tool for analyzing online games.

This article proposes a design and implementation methodology of a gesture-based interface for augmented reality games. The topic of gesture-based augmented reality games is a promising area in the immersive future games using human body motions. However, due to the instability of the current motion recognition technologies, most previous development processes have introduced many ad hoc methods to handle the shortcomings and, hence, the game architectures have become highly irregular and inefficient This article proposes an efficient development methodology for gesture-based augmented reality games through prototyping a table tennis game with a gesture interface. We also verify the applicability of the prototyping mechanism by implementing and demonstrating the augmented reality table tennis game. In the experiments, the implemented prototype has stably tracked real rackets to allow fast movements and interactions without delay.

The Korean military has developed and operated computer, network, communication technologies as well as war game models to strengthen the national defense M&S continuously. In particular, lots of projects for developing models for drill/training, analyses, and acquired fields are being conducted in the military. However, it needs to look into the actual conditions and seek for strategies to develop the national defense M&S. First of all, in the field of war games, various national defense architectures have been built, including war and information environment architectures starting from the resource architecture in 2006. However, the function of drill and training is limited, so additional war game architectures are required to be built. To build joint war game architectures available as an effective verification tool to implement plans of the national defense and war architectures, this study examines the actual conditions of the current war game systems and suggested building joint war game architectures.

This study suggests a methodology for automatically extracting placing information from 2D reinforced concrete details drawings and generating a 3D reinforcement placing model to develop a mobile augmented reality for bar placing work. To make it easier for users to acquire placing information, it is suggested that users takes pictures of structural drawings using a camera built into a mobile device and extract placing information using vision recognition and the OCR(Optical Character Registration) tool. In addition, an augmented reality app is implemented using the game engine to allow users to automatically generate 3D reinforcement placing model and review the 3D models by superimposing them with real images. Details are described for application to the proposed methodology using the previously developed programming tools, and the results of implementing reinforcement augmented reality models for typical members at construction sites are reviewed. It is expected that the methodology presented as a result of application can be used for learning bar placing work or construction review.

It is no longer special for the gaming industry to provide a community to promote their games. Much prior research related to the community also focuses on the spread of community influence and its importance. In particular, the user community in the gaming industry is having a big impact on the company's revenue creation beyond the simple level of information provision and promotion of friendship. Therefore, providing a community at the same time as the game is released is becoming a common trend in the gaming industry This study attempted to explore factors influencing the design of more effective communities under the assumption that the user community will influence the loyalty of mobile games. The design elements of the community suggested in this study are the provision of interaction tools between users, the provision of information, and communication between the game maker and the users. This study aims to confirm that these design factors affect customer loyalty by reinforcing user empathy and trust in the game within the user community. After collecting data from 251 users active in the mobile game user community, the model presented in this study was empirically analyzed. As a result, the design elements of the game community suggested in this study were found to affect customer loyalty by strengthening the empathy for the game and the trust in the game developer.
