The popularity of Pokemon games has raised the interest in outdoor augmented reality games. This paper introduces a handgun type motion controller for an outdoor augmented reality shooting game and augmented reality game contents linked to it. The existing augmented reality game controller can only operate the game with the trigger interaction, but the proposed device can also operate the game with motion interaction. A motion-based game controller allows you to immerse yourself in Outdoor AR FPS game.

Automation and robotization has been required in construction for several decades and construction industry has become one of the important research areas in the field of service robotics. Especially in the steel construction, automatic recognition of structural steel members in the stockyard is emphasized. However, since the pose of steel frame in the stockyard is site dependent and also the stockyard is usually in the outdoor environment, it is difficult to determine the pose automatically. This paper adopts the recognition method based on the augmented reality to cope with this problem. Particularly focusing on the light condition of the outdoor environment, we formulated the optimization problem with the constraint and suggested the methodology to evaluate the optimal camera arrangement. From simulation results, sub-optimal solution for the position of the camera can be obtained.

Recently, at home and abroad cultural content industry has developed as the growing importance of history. Among them, the reconstruction contents area which combined with IT technology is attracting attention. Specially, using augmented reality technology, 3D visualization researches which restore contents of architectural heritage, cultural heritage sites, and artifacts have been performed in cultural content area. The existing cultural site restore contents are mostly made based on the images taken from indoor. In this paper, efficiently visualize the restore contents in indoor, but outdoors is limited. This theses presents the cultural heritage sites 3D model visualization system using augmented reality in outdoor. Proposed system augments 3D model to cultural heritage site in outdoor by using Smart Phone.

In this paper, we preset a method for the development of u-GIS outdoor augmented reality(AR) system. The proposed system is consist of three parts. First, sensor acquisition and calibration for AR, Second, camera and sensor based tracking for AR, Third, integration of sensor information and 3D models. We combine spatial information of real and virtual spaces through u-GIS AR system.

Interest in Augmented Reality (AR) game $Pok{\acute{e}}mon$ GO is getting heightened. However, based on its characteristic, various direct and indirect problems are highlighted, thus increasing concerns. Although the game is not formally released domestically, there are limits in national game classification to apply on such outdoor Augmented Reality game. This paper will examine the problematic cases regarding Pokemon GO and analyze internal and external game classification system to discuss safe gaming measures for domestic users. In result of examining cases, need for adding 'physical danger' in current game classification system for user's safety was shown. As the government's game regulation is being eased, appearance of a variety of games using Augmented Reality technology in near future is predicable. Therefore it is important to prepare improvement of game classification system as a pre-safety measure, and it is expected to bring positive effect on game usage and industrial growth through safe game usage.

In this paper, a view point tracking system has been realized for outdoor augmented reality including broad area monitoring. Since the surroundings of the moving view point are changing, it is necessary to track the position and observation moment of the view point system for consistency between real and virtual images. For this reason, the GPS(Global Positioning System) is applied to the realized system for tracking the information on position and direction of the moving system. In addition, an optical position tracking system that is able to track view point in a limited area is used, because the local tracking system has to trace the image variation, seen to the observer in a moving vehicle, at a particular position and time. It was found that the realized outdoor augmented reality system, which combined the virtual information tracked in real time with the real image, can be very practical in various application area.

Augmented Reality technologies offer new possibilities to the exploration of spatial distributed information. In this work we describe the main issues in the development of an Augmented Reality system that allows the annotation of objects or features in the real world captured by a camera. The general operation of this kind of systems is described, as well as the main problems that need to be solved. Finally, as an example of case of study, we present an application for the annotation of information relative to containers in a marine terminal.

Outdoor sports activities have been restricted by serious air pollution, such as fine dust and yellow dust, and abnormal meteorological change, such as heatwave and heavy snow. These environmental problems have rapidly increased the demand for indoor sports activities. Virtual sports, such as virtual golf, virtual baseball, virtual soccer, etc., allow playing various sports games without going outdoors. Indoor sports industries and markets have seen rapid growth since the advent of virtual sports. Most virtual sports platforms use screen-based virtual reality techniques, which are why they are called screen sports. However, these platforms cannot support various sports games, especially virtual match games, such as squash, boxing, and so on, because existing screen-based virtual reality sports techniques use real balls and players. This article presents screen-based haptic-augmented reality technologies for a new virtual sports platform. The new platform does not use real balls and players to solve the limitations of previous platforms. Here, various technologies, including human motion tracking, human action recognition, haptic feedback, screen-based augmented-reality systems, and augmented-reality sports content, are unified for the new virtual sports platform. From these haptic-augmented reality technologies, the proposed platform supports sports games, including indoor virtual matches, that existing virtual sports platforms cannot support.

Recently, as AR(Augmented Reality) technology develops, it is used in field of diverse industry and specially affects structures and human interaction in field of architecture. This paper proposes 3D visualization application for realistic experience of structures by using outdoor AR technology. Proposed application visualizes structures such as high buildings, bridges, ships, and so on to be constructed in future, considering ambient environment by using outdoor AR technology, provides precisely user structures after completing construction and offers more realistic information and immersion as compared with previous methods.

In this paper, we developed an outdoor augmented reality system which has remote real scences acquisition ability. The real scenes acquisition system consists of image acquisition system, tracking system, wireless data transceiver and power supply. Tracking system that consists of Tans Vector and RT-20 measures a position and attitude of the CCD camera that attached at the remote control helicopter. Wireless data transceiver system is utilized for data transmission of remote system that of attitude, position information, andreal scenes data that acquired by the CCD camera. Maximum propelling power of remote control helicopter is 15Kg, so we used 7.2V li-ion cell as a power supply for system minimize. As the results of experiment, the developing system presented application possibility of remote information acquisition system such as construction simulation & estimation, broadcasting, tour guide.
