Consumer responses to 3D online shopping malls are influenced by their attitudes toward technology. This study examines the consumer differentiation according to technology readiness, compares customers with different technology readiness in terms of their perceived telepresence and e-loyalty, and examines the effect of their perceived telepresence on their e-loyalty. Samples from 300 females aged 21 to 39 were used for the final analysis. The results are as follows. First, consumers were classified into three groups, Explorers (N=72), Pioneers (N=105), and Skeptics (N=123), through factor analysis and k-means cluster analysis. Second, the Explorers evaluated the telepresence of the 3D online shopping mall higher than any other group. The Skeptics presented lower e-loyalty and perceived less telepresence in the 3D online shopping mall than the other two groups. Finally, telepresence had a significant influence on e-loyalty, as identified by the regression analysis. This verifies the effectiveness of 3D technology adopted or to be adopted by online shopping malls and demonstrates that 3D shopping malls can be a strategic alternative in the online shopping sector where competition is fierce. The results show that online shopping malls should focus on establishing 3D shopping environments with further effort to utilize the technology.

As studies on more realistic human-robot interface are being actively carried out, people's interests about telepresence which remotely controls robot and obtains environmental information through video display are increasing. In order to provide natural telepresence services by moving a remote robot, it is required to recognize user's behaviors. The recognition of user movements used in previous telepresence system was difficult and costly to be implemented, limited in its applications to human-robot interaction. In this paper, using the Nintendo's Wii controller getting a lot of attention in these days and infrared LEDs, we propose an immersive user interface that easily recognizes user's position and gaze direction and provides remote video information through HMD.

In the construction phase, the existing schedule management system by 4D CAD has been difficult to check for a status and progress of construction product in real-time because it simulates only VR (virtual reality) object based on a planned schedule. This study suggests a construction schedule management system by telepresence technique that can visualize progress status in real-time by using 4D CAD system based on remote monitoring. The telepresence methodology and system were developed in the study and they were verified for a railway construction project. The developed system can examine the status and progress of construction because it can compare 4D simulation based on planned schedule with real-time site images through web-camera.

최근 건설 사업에서는 다양한 형태의 전산화 도구들을 현장에 적용하기 위한 노력이 진행 되고 있다. 그러나 철도시설과 같은 광역지역을 효율적으로 관리하기 위해서는 VR (Virtual Reality, 가상현실) 기술을 활용한 원격기반의 정보화 기법이 도입될 필요가 있다. 이를 위 본 연구에서는 VR과 Telepresence 기술을 통합한 실시간 현장 원격관리체계 구축 및 AR (Augmented Reality, 증강현실) 연동 방법론을 제안하며, 제시된 방법론의 실무 적용 성을 검토하고 있다. 이러한 가상건설지원 체계는 건설실무자와 시스템간의 실시간 상호작용을 가능하게 하며, 통합된 현장 진도 상황정보를 효율적으로 파악 할 수 있는 도구가 될 수 있을 것으로 기대된다.

The purpose of this study is to analyze the economic effects of telepresence system for public sector relocation. As a Green IT system, the importance of telepresence is being recognized increasingly as a means to replacing a majority of business trips and thereby reducing greenhouse gases emitted in the process. However, there are only a few related researches that analyze the economic effects of telepresence at the moment. This study conducts the cost-benefit analysis of 157 public sectors which are to relocate from 2012 based on the sample case of National Information Society Agency. The results obtained reveals that telepresence would save about 180 billion won and reduce about 580t $CO_2$ emission. This study are expected to provide the academic framework for organizations contemplating the adoption of Green IT system moving forward.

With the advent of smart age, the concern on smart work has gradually increased in solving our social problems including low birth, aging, low productivity and green growth with low carbon as well as encouraging the balance between work and life. Especially, the competitiveness among companies and countries to preoccupy the advanced telepresence technologies and lead the international standardization based on them have increased more than ever before. But, in our country due to the lack of core technology infrastructure and barrier to current organizational culture, R&D achievement and promotion of deployment on telepresence have not been sufficient. Therefore, It is essential to make standardization strategy and do systematic implementation for core technology which leads the telepresence market in order to fit such an environment and introduce smart work as soon as possible. Accordingly, this paper suggests the direction of standardization and implementation on telepresence for our country to lead telepresence technology and standardization through analysing the current introducing situation and technology/standardization trend.

Telepresence in robot assisted learning has preferred low-height, shorter than life-size robotic platforms for reasons such as operational stability, user convenience and psychological comfort in human robot interaction. If, however, the reason for using a telepresence robot is to display the authority of a social superior to a social inferior, one can hypothesize that a robotic platform which reflects real-life height advantage would be better suited for the stated purpose than conventional low-height platforms. In order to test the hypothesis, we examined whether the height of the robot had an effect on an instructor connected to a telepresence robot in robot-assisted learning with regard to controlling a large number of elementary school students. The pre-and post experiment demonstrates that the use of a life-size telepresence robot, compared to a child-size telepresence robot, failed to make a meaningful difference in the instructors' authority being accepted by the students. However, behavioral measures shows that a taller robot has more merits in controlling students.

This study utilizes a S-O-R model to investigate the effects of apparel product presentations using a 3D avatar model in Internet fashion malls for pleasure(emotional state) and approach behavior. We chose a 3D avatar model to present a fashion product in this study. The model walked for about one minute on stage; subsequently, respondents completed a questionnaire after they viewed it. The questionnaire consists of telepresence, pleasure and approach behavior. Respondents are limited to females 20s and 30s years old who have purchased fashion products in an Internet mall and are highly interested in fashion products. A total of 226 samples were used for the final analysis. Cronbach's alpha, correlation analysis, confirmatory factor analysis, and structural equation modeling were utilized in this study. The results are as follows. First, telepresence has a significant influence on pleasure; subsequently, pleasure influenced consumer approach behavior. Second, telepresence positively influenced the approach behavior (directly and indirectly). This verified the effectiveness of a 3D avatar model using S-O-R. A 3D avatar model can be a strategic alternative in the fiercely competitive Internet shopping sector.

The purpose of this study was to explore children and robot interaction in distant language learning environments using three different video-conferencing technologies-two traditional screen-based videoconference technologies and a telepresence robot. One American and six Korean elementary school students participated in our case study. We relied on narratives of one-on-one interviews and observation of nonverbal cues in robot assisted language learning. Our findings suggest that participants responded more positively to interactions via a telepresence robot than to two screen-based video-conferencings, with many citing a stronger sense of immediacy during robot-mediated communications.
