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.

Over time, the beauty industry has entered a mature industry and cannot survive unless it changes. In reality, the AR market for virtual experimental marketing is growing in the beauty industry, and global companies like FACEBOOK in the US are investing heavily in AR. Therefore, this study utilizes augmented reality technique to find out how the experience of using AR application affects female consumers' satisfaction and how they feel. This study will focus on how the relationship with purchase intention is mediated. In addition, we will help to suggest the development direction of augmented reality with makeup by analyzing the overall factors at the time when new technology, augmented reality marketing is becoming active.

Natural User Interface(NUI) technologies introduce new trends in using devices such as computer and any other electronic devices. In this paper, an augmented reality on a mobile device is implemented by using face detection, recognition and motion tracking. The face detection is obtained by using Viola-Jones algorithm from the images of the front camera. The Eigenface algorithm is employed for face recognition and face motion tracking. The augmented reality is implemented by overlapping the rear camera image and GPS, accelerator sensors' data with the 3D graphic object which is correspond with the recognized face. The algorithms and methods are limited by the mobile device specification such as processing ability and main memory capacity.

Recently, by increasing the number of smartphone users, the applications for product brochure and advertising service using a technology of augmented reality are also taking place exponentially. The term, augmented reality, is an application of providing composite view with real world and virtual world, and synthesizing the information to make it look-like things that exist in the actual environments of the original real world. In this paper, we present the trends of core technologies and the standardization related on augmented reality in the mobile environment, and discuss the necessary of standards related to image-based augmented reality.

Advertisement market using the augmented reality has been rapidly increasing recently due to integration with LBS(location based services). This study was conducted to examine the effect and acceptance intention of mobile augmented reality advertisement through TAM(Technology Acceptance Model). 'Contextual feature,' which is a characteristic of augmented reality advertisement, was selected as an outside effective variable, and perceived usefulness and perceived ease of use, which are the core variables of TAM, and attitude of advertisement and advertisement acceptance intention were selected as important evidences of Technology Acceptance Process. Also, the relationship between each evidences were investigated. As a result of the investigation of the outside influence on the acceptance model of augmented reality advertisement, it was shown that the contextual feature of augmented reality advertisement had meaningful influence on perceived usefulness and perceived ease of use, and it was also shown that it has positive influence on the attitude of advertisement and acceptance intention of advertisement.

Black marker cause unnatural problems between the existing various contents and marker. To solve this problem, we tested frequency of 3D objects according to the various colors and color placement. Based on this, infant's learning content system based NyARToolkit for the mobile-based augmented reality was implemented. By insert to color marker, We are solved the unnatural problems in the Implemented system. and infant can study seamlessly because concentration increases by the familiar character on the markers.

Since the launch of Pokémon GO in 2016, the game has been loved for many users. Although the number of Pokémon GO users has declined, lots of users still enjoy the location-based augmented reality game. From the perspective of game properties and Use & Gratifications theory, this paper investigated the antecedents of continuance intention of Pokémon GO. A total of 258 responses from Pokémon Go users was collected by an online survey. The result of regression analysis showed that attitude toward game characters, attitude toward random game elements, social interaction, competition, and physical activity increased continuance intention. Perceived cost, however, decreased continuance intention. Implications for researchers and practitioners were discussed.

This paper proposes a mobile augmented reality system to provide detail information of the products using QR code included in them. In the proposed system, we perform the estimation of the camera pose using both of marker-based and markerless-based methods. If the camera can see the QR code, we perform the estimation of the camera pose using the set of rectangles in the QR code. However, if the QR code is out of sight, we perform the estimation of the camera pose based homography between consecutive frames. Moreover, the content of the augmented reality in the proposed system is made by using meta-data. Therefore, the user can make contents of various scenario using only meta-data file without modification of our system. Especially, our system maintains the contents as newly updated state by the on-line server. Thus, it can reduce the unnecessary update of the program.

As the recent advances in network and wireless communications and semiconductor design and process technologies, our computing platform is rapidly shifting from desktop PCs to mobile devices such as UMPC (Ultra Mobile PC), Tablet PC, and Smartphone. Especially, wide-spreading Smartphones allow a new field of application based on location based services available with an user interface called augmented reality (AR). Therefore, this paper introduces an implementation of AR using various OpenAPls on Android Smartphones. In order to utilize enrich user data in real time, the system integrates with location based social network services also with OpenAPI. These APIs enable third-party developers to make use of rich contents of many portal web sites. The prototype was implemented on the real Android phone, Sky Sirius, and the result shows that it can provide an efficient location based service using AR technology without any constraints on mobile devices; in addition, it connects SNS to AR for sharing user data including photos, videos, and messages based on a specific location.

This paper introduces a mobile augmented visualization technology that augments a three-dimensional virtual human body on a mannequin model using two pose(position and rotation) tracking sensors. The conventional camera tracking technology used for augmented visualization has the disadvantage of failing to calculate the camera pose when the camera shakes or moves quickly because it uses the camera image, but using a pose tracking sensor can overcome this disadvantage. Also, even if the position of the mannequin is changed or rotated, augmented visualization is possible using the data of the pose tracking sensor attached to the mannequin, and above all there is no load for camera tracking.
