가상현실의 자연스러운 응용분야는 작업 훈련(Task Training) 분야이다. 이러한 작업 훈련 분야에서 가장 중요한 요소 중 하나는 각성 수준(Arousal Level)으로, 적절한 각성 수준은 과제 훈련의 효과를 결정짓는다. 본 연구는 VR 환경과 Desktop 환경의 자동차 운전 시뮬레이터에서 피험자가 실험을 위하여 설계된 2 개의 시나리오를 수행하는 동안 피험자의 생리 신호를 측정하고, 실험 후 각 환경에 대한 주관적인 실재감을 측정하여, 두 실험 환경 사이에 피험자의 주관적인 실재감이 유의한 차이가 있는지 알아보고, 피험자가 수행한 시나리오와 시나리오에 종속된 실험 태스크에 대하여, 각성 수준을 평가할 때 유용한 지표로 활용되는 피부전도도(GSR) 반응이 피험자의 주관적인 실재감의 결과와 어떠한 관계를 보이는지 살펴 보았다. 실험 결과 두 실험 환경 사이의 피험자의 주관적인 실재감은 유의한 차이가 있었고, VR 환경에서 더 높게 나왔다. 그러나 두 실험 환경 사이의 피험자의 생리적 각성 반응은 실재감의 결과처럼 유의한 차이를 보여주지 못했으며, 오히려 시나리오에 종속된 실험 태스크에 따라서 유의한 차이를 보여주었다. 따라서 실재감과 피부전도도 (GSR)측정에 의한 각성도 는 직접적인 관계가 적은 것으로 생각되며, 이는 피부전도도(GSR)를 실재감의 한 척도로 쓰기에는 적합하지 않을 수 있다는 것을 의미한다.

Smart tourism is a social phenomenon arising from the convergence of information technology with the tourism experience. New ways of doing business, new patterns of experience and new problems concerning tourism destination image management and marketing are emerging due to the ubiquitous presence and influence of the internet and mobile devices. New conceptual tools are also available to enable researchers to further understand the social implications as well as the practical implementation of these new virtual and augmented smart tourism ecosystems. To this effect this paper introduces the constructivist paradigm and associated research methodologies as another toolbox for interpreting how smart tourism works as a form of soft power. The implications revealed by constructivism are that through smart tourism ecosystems, destination commodification and commoditization, experience and image formation are increasingly self-perpetuating, autonomous and organic social constructions. Researchers in information technology can use constructivist research to further explore these dynamic developments in smart tourism.

This paper presents an approach to exercise that utilizes motion capture through the Rokoko Smart Suit. With the emergence of Covid-19, physical fitness levels have declined due to restrictions on in-person fitness classes and gym closures. To maintain physical activity, many individuals have turned to mobile applications and streaming videos. However, home workouts often lack the motivation and experience found in gyms, classes, or community centers, particularly with the presence of coaches and instructors. Additionally, instructors find it challenging to convey precise postures to their online students, and vice versa. To address this issue, the researchers propose the use of a full-body tracking suit like the Rokoko Smart Suit, which enables instructors to present a more realistic approach to physical activity. The Rokoko Smart Suit offers a 3D view of the instructor, eliminating the limitations of camera scope when streaming on platforms like Zoom or MS Teams. This technology enhances the at-home workout experience, and the incorporation of 3D virtual reality features can further elevate the realism of a workout.

This study investigates the virtual reality (VR) simulation to train construction workers for modular construction. Recently, the construction industry has been experiencing a growing demand for modular construction due to a shortage of labors and an increasing social need for safety. While the demand for modular construction has been increasing, construction labors suffer a basic knowledge regarding modular construction. The users of the simulation, developed by Unity program and Oculus Quest 2, experience the removal of hazardous elements at the location whether the modular unit suspended by a crane is lowered, the lowering and assembly of units through crane operation, and the fall from the roof which is the most frequent accidents in modular construction. The simulation was tested by 15 subjects. The effectiveness of the education was measured through a survey on self-efficacy, perceived usefulness, usability, and presence. It was found that the VR training is suitable for educating on the modular construction activities and safety issues related to them. This study also found that perceived usefulness is the factor that has the greatest impact on self-efficacy. This study can contribute to resolving the labor education issues for the deployment of modular construction.

In line with the rapid spread of Metaverse in various marketing areas, fashion companies have also begun to devise various activities using the Metaverse. Fashion experiences within the Metaverse platform must be conducted considering the characteristics of the Metaverse itself. However, there has yet to be any research on Metaverse fashion based on the characteristics of the Metaverse platform itself. Accordingly, this study sought to empirically analyze the impact of various characteristics of the Metaverse platform on consumers' virtual fashion experience within the platform. In particular, this study focused on the relationships among the Metaverse platform characteristics, perceived avatar identity, and the purchase intention of actual fashion products. In order to test the hypotheses, a survey was conducted on 300 Korean male and female consumers with an average age of 39.3 who had experience with virtual fashion through the Metaverse platform. In response to the recent increase in domestic and foreign brands' attempts to experience fashion using ZEPETO, the questionnaire provided an experience scenario that included detailed captured images of the use of avatars in the ZEPETO world. Data was subjected to statistical analysis using the SPSS 28.0 program. The results confirmed that the characteristic factors of the Metaverse platform (i.e., presence, social interactivity, anonymity) had a significant impact on the user's perceived avatar identification. Additionally, perceived avatar identity significantly affected users' purchase intention. Theoretical and managerial implications and study limitations are discussed.
