Allowing on-site workers to access information of the construction process can enable task control, data integration, material and resource control. However, in the current practice of the construction industry, the existing methods and scope is quite limited, leading to inefficient management during the construction process. In this research, by adopting cutting edge technologies such as Augmented Reality(AR), digital twins, deep learning and computer vision with wearable AR devices, the authors proposed an AR visualization framework made of virtual components to help on-site workers to obtain information of the construction process with ease of use. Also, this paper investigates wearable AR devices and object detection algorithms, which are critical factors in the proposed framework, to test their suitability.

It is challenging to select appropriate technology in education to interact with students in today's digital world. Especially when the technologies used at home on smart devices like tablets and mobile phones are very advanced, on the other side, it may be more challenging to find sharing technology in the classroom. One of the ways is to use new technologies like Augmented Reality (AR). The current study aims to develop usability principles for the development and evaluation of education using AR technology applications. We develop usability principles for AR applications by analyzing existing research about heuristic evaluation methods, design principles for AR systems.

This study aimed to examine an augmented reality-based teaching simulation in a mobile application. We examined how AR-enabled interactions affect users' perceived scenario usefulness and avatar realism. The participants were forty-six undergraduate students. We randomly grouped them into two conditions: AR and Non-interactive video groups with equal sample sizes. This study employed an experimental design approach with a one-way multivariate analysis of variance with repeated measures. The independent variable is the presence/absence of AR interaction with a mobile application. The dependent variables were avatar realism and scenario usefulness. The measures explored how the student avatar's emotional intensity in a scenario influences user perception. The results showed that participants in the AR-interaction group perceived avatar realism significantly higher than those in the non-interactive video group. Also, participants perceived the high emotional intensity scenario (aggression toward peers) to be significantly higher usefulness than the low emotional intensity scenario (classroom disruption).

Technology has been changing the travel experience of visitors. Particularly, augmented reality (AR) is one of the emerging technologies, which widely used in cultural heritage tourism sites. This study is based on a new technology acceptance model and future modified this model to examine the relationship between product beliefs, consumer satisfaction with AR, and destination loyalty in cultural heritage sites. Moreover, this paper examined the role of technology readiness (TR) forming travellers' loyalty of destination with a kind of travel technology--AR. The results show that perceived usefulness and perceived ease of use have significant effects on the satisfaction of AR towards the travellers' loyalty of destination. TR is found to have moderating effects on this model.

After the Pokemon game became popular, the popularity of the Augmented Reality game is higher than ever. Therefore, it is an important choice to use an engine to create an augmented reality game. It explains how to create an augmented reality game using Unity engine, which is one of the most used game engines in game development. We describe a method for implementing augmented reality optimized for games by selecting a MARKERLESS method that does not require a marker among the augmented reality techniques. In this paper, we propose a technique to create MARKERLESS augmented reality game using KUDAN AR engine which supports Unity engine and unity through 'Our Hero' project.

Parents' influence on children's development is generally considered essential. This paper attempts to explore the role of AR in preschool education from the perspective of parents, aiming to help parents better understand the impact of children's use of augmented reality in preschool education. The subjects were parents of children in the preschool age range (3-6 years old), and the experimental equipment was AR cognitive cards. In order to extract parents' views on AR, five parents were invited to conduct an experiment with their children using AR cognition cards, and then an open interview survey was conducted. In the second experiment, the answers obtained from the first experiment were sorted out and formed a questionnaire to conduct a closed-book survey. It shows that parents are satisfied with the characteristics of AR to assist their children's learning. At the same time, parents also value technology, usage management and playing environment. AR can stimulate children's learning initiative. Children like to use AR, AR is suitable for learning, make parents satisfied. But even if AR is suitable for learning, parents will control the time their children use it.

In monitor-based AR(Augmented Reality) systems, it is required to know the position and direction of a camera in order to combine real images from a camera with virtual images exactly_ Because a tracker is parted from a camera, however, there is a registration error caused by the inconsistency of a tracker with a camera. In this paper, we describe the error correction method using genetic algorithm. This method looks for the position and direction of a camera using genetic algorithm and solves the error correction matrix of it. And then it is registered of the real images and the revised virtual image. It has an effect on the error correction caused by the misalignment of a tracker with a camera in complex AR systems.

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.

Hwaseong Fortress was designated as a World Heritage Site by UNESCO in 1997 in recognition of its architectural, cultural, and historical significance. In order to provide a compelling and active experience to the visitors of Hwaseong Fortress more effectively and intuitively, an augmented reality (AR) mobile application is developed. The main objective of this paper is to describe the implementation of AR technology in the developed application; and most importantly, how the application is designed for the visitors to actively and intuitively experience the various architectural and historical contents of Hwaseong. The tour routes and their point of interests were selected carefully after deliberation of their contents. To maximize the user interaction with the application and the architectural contents of Hwaseong, not only the conventional AR technology (marker method), but also the markerless AR method is adopted in the developed application. It is expected that visitors of Hwaseong Fortress enjoy the tour, while learning the architectural, historical, and cultural contents through the active and intuitive interaction with the developed AR mobile application.

Recently, augmented reality and virtual reality in the ICT sector have been highlighted. So also interested in related HMD areas to facilitate contact with the VR content is being attend. This paper proposes a method for implementing to the virtual reality through the mobile HMD device with the real time 360 image. This system is required the real time 360 image streaming server configuration and image processing for augmented reality and virtual reality. The configuration of the streaming server is configured the DB server to store images and the relay server that can relay images to other devices. Augmented image processing module is composed based on markerless tracking, and there are four modules that are recognition, tracking, detecting and learning module. Also, the purpose of this paper is shown the augmented 360 image processing through the Mobile HMD.
