The paper presents a framework for developing real-time multi-user board games and applications in augmented reality. Recently, increase the environment to playing game in augmented reality with advancement of computing ability improvement and wireless networking technique of mobile device. While the trend of utilizing this kind of games is creasing, the facts that there is a shortage of games whose contents are attractive to users. In this paper we propose a framework that enables game content developers to develop new game contents base on augmented reality easily and quickly. This framework is an automatic service that can augment in various methods by using the supported marker recognition service. Therefore game contents developers do not need to know about either augmented reality technique or the inner process structure. The framework also supports special functions and various interaction interfaces for augmented reality board game and components of the board game we can implement. These enable developers to accomplish all the necessary components and structures of the board game more easily.

This essay analyzes space in augmented reality games, and attempts to offer space analytic standards of mobile augmented reality games in regards to space in existing games. This article proposes categorizing criteria based on the following factors: Analysis of space in existing games, Jason Jerald's Three Virtual Space Horizon Categories, interaction between virtual world and real world, and Lavroff's Three deciding factors of reality perception in virtual reality. It is meaningful that the analysis criteria of the Augmented Reality game space is presented through this analysis.

Recently, various methods have been studied and developed to develop the local cultural contents industry. This research has produced a mobile AR augmented reality game that anyone can easily access by developing contents that can be enjoyed with new tourists. It aims to spread 10 million tourists to surrounding tourist attractions by developing a new storytelling-based AR game using the symbol of Jeonju, which is the birthplace of the Joseon Dynasty, and promote economic value-added activities in nearby stores. GPS technology and AR marker-based action augmented reality games will be newly established as cultural contents based on new regional scenarios. Augmented reality games that combine visual resources are increasing values of local brands by playing games at Jeonju tourist attractions.

The game industry has changed along with the advancement of device technology. The wearable, a recently appeared device will create new demand in this saturated age of the smart devices. The game industry's content targeted towards the wearable devices will play an important role as main driving source. For this reason, this research studies the development aspect and the current technical capabilities of games' platforms and contents by analyzing the contrast between the results of features and current situations of the wearable market. Consequently, we define the prospects of game content for wearable device. We also expect that the new style of the game content, combined with cloud game, augmented reality game and virtual reality game will appear in the next generation platforms gearing towards the wearable devices.

This study investigates the merits of incorporating augmented reality in mobile games and proposes a mobile game application that combines augmented reality technology with gaming. The proposed study postulates that augmented reality technology can be employed for developing games on smartphones. The proposed application involves the implementation of a 3D virtual object in the real world by incorporating a target image. The proposed application also employs an intuitive interface with simplified manipulation based on touch, and allows players to collect and combine items for acquiring new items, thus making it elementary to pass the game stages. Furthermore, a ranking system has been introduced in the proposed application for enhancing the amusement factor of the game. The novelty of the proposed application lies in the fact that the virtual button function has been employed for combining physical and virtual objects while playing the game, without incorporating location-based services.

This study aims to investigate the influence of engagement of augmented reality game on immersion. The relationship between engagement and flow was examined through the mediating effects of emotional attachment and focus of attention on presence and the mediating effects of presence on flow. In order to verify the research hypothesis, online questionnaire was conducted with the consent of $Pok\acute{e}mon$ Go game user group. The questionnaire items were translated from the Augmented Reality Immersion Questionnaire. A total of 200 questionnaires were collected and used for analysis. Using the SPSS 23.0 program and the Mplus 7.0 program, the reliability of the scale was confirmed through the Cronbach's coefficient and the causal relationship and the mediating effects were verified by path analysis. As a result, there was no direct causal relationship between engagement and flow. However, causal relationship was evident when emotional attachment and focus of attention were mediated in the process of engagement in augmented reality game. In conclusion, systematic explanations of participant's emotional attachment and attentional state as a main factor in the process of participating in the augmented reality game involvement, reveal the elements to be noticed by the augmented reality game.

In recent, mobile augmented reality game which has been attracting high attention is considered to be an good approach to increase immersion. In conventional augmented reality-based games that recognize target objects using a mobile camera and show the matching game characters, touch-based interaction is mainly used. In this paper, we propose an intuitive interaction method which manipulates a deformable game object by moving a target image of augmented reality in order to enhacne the immersion of the game. In the proposed method, the deformable object is intuitively manipulated by calculating the distance and direction between the target images and by adjusting the external force applied to the deformable object using them. In this paper, we focus on the cloth deformable object which is widely used for natural object animation in game contents and implement natural cloth simulation interacting with game objects represented by wind and rigid objects. In the experiments, we compare the previous commercial cloth model with the proposed method and show the proposed method can represent cloth animation more realistically.

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.

In this study, by using the control technique of the user using augmented reality technology, to provide a game system touch-based. The augmented reality technology, can be advantageously used vehicle is easily recognized as a technique for synthesizing (images, video, text) object of the virtual image of the real world. Augmented reality technology has been studied to make the application in various fields. Studies of natural marker-based marker and base are underway, but there is no sense of incongruity in reality research natural marker-based and has been studied much. By using the augmented reality technology natural marker-based In this paper, we implemented a game system. The system also has the advantage that can be absorbed in the game by using the techniques of the interaction through a user's touch. Touch interface-based, are available as well as user environments, even in mobile devices such as smart-phone and touch pad.
