The objective of this study is to compare the efficiency of VR and 2D in the tourism industry as marketing tools, using affective forecasting and purchase intention. Accordingly, this study has two primary research aims. The first is to examine if a higher level of mental imagery (resulting from VR) is more effective than a lower level (2D) in a tourism marketing context. To evaluate this, the researchers use experimental method, measuring predicted dominance, predicted pleasure and predicted arousal, as well as purchase intention towards the hotel. Relevant to the tourism industry, tourism products are spatially and temporally distant (vs. near). This study aims to investigate how differently mental imagery, resulting from VR (versus 2D) experience, generates affective forecasting of a tourism product when tourists plan distant (versus near) future trips (temporal distance).

Background: Virtual reality (VR) programs based on motion capture camera are the most convenient and cost-effective approaches for remote rehabilitation. Assessment of physical function is critical for providing optimal VR rehabilitation training; however, direct muscle strength measurement using camera-based kinematic data is impracticable. Therefore, it is necessary to develop a method to indirectly estimate the muscle strength of users from the value obtained using a motion capture camera. Objects: The purpose of this study was to determine whether the pedaling speed converted using the VR engine from the captured foot position data in the VR environment can be used as an indirect way to evaluate knee muscle strength, and to investigate the validity and reliability of a camera-based VR program. Methods: Thirty healthy adults were included in this study. Each subject performed a 15-second maximum pedaling test in the VR and built-in speedometer modes. In the VR speedometer mode, a motion capture camera was used to detect the position of the ankle joints and automatically calculate the pedaling speed. An isokinetic dynamometer was used to assess the isometric and isokinetic peak torques of knee flexion and extension. Results: The pedaling speeds in VR and built-in speedometer modes revealed a significantly high positive correlation (r = 0.922). In addition, the intra-rater reliability of the pedaling speed in the VR speedometer mode was good (ICC [intraclass correlation coefficient] = 0.685). The results of the Pearson correlation analysis revealed a significant moderate positive correlation between the pedaling speed of the VR speedometer and the peak torque of knee isokinetic flexion (r = 0.639) and extension (r = 0.598). Conclusion: This study suggests the potential benefits of measuring the maximum pedaling speed using 3D depth camera in a VR environment as an indirect assessment of muscle strength. However, technological improvements must be followed to obtain more accurate estimation of muscle strength from the VR cycling test.

The decommissioning process of Kori Nuclear Power Plant No.1, which was permanently suspended in 2017, various studies and attention on the decommissioning of nuclear power plants and waste management are being focused. In particular, decommissioning of high-risk facilities should take into account both safety and economic aspects. Small defects in the decommissioning process may lead to major disasters, and the resulting economic losses will cause enormous damage at the national level. In order to prevent such damage, various decommissioning process simulations within a virtual environment should be performed, and process errors and results should be collected and analyzed through simulation to derive the optimal decommissioning scenario as possible. The platform introduced in this paper builds a virtual environment based on drawing and modeling data of Kori Nuclear Power Plant No.1 and automatically creates an optimized cutting path for dismantling the facility and internal structure, and simulates a cutting process similar to reality using Robot Arm. In addition, it is possible to derive and analyze a cutting process scenario by processing process results such as time required for work and cutting distance collected through simulation.

The goal of this study was to develop a haptic communication system that can convey the tactile sensation of fashion materials in a virtual environment. In addition, the effectiveness and how realistically the virtual fabric image of this system delivers the tactile sensation of actual fabric was verified. First, a literature review was conducted through which the tactile attributes of fashion materials were defined that would be implemented in the haptic communication system. Then, a questionnaire for evaluating the tactile attributes of fashion materials was developed. Next, a haptic communication system was designed to convey fashion image experiences in a virtual environment, from which a haptic rendering model was suggested. The effectiveness of the haptic communication system was evaluated by verifying user experiences with questions developed through a user evaluation experiment. The validity of the evaluation questions pertaining to the tactile attributes and the effects of the haptic communication system were verified. Factor analysis was conducted to verify the evaluation of the tactile sense attributes of the fashion material, which identified density, thickness, and elasticity of the material as key factors. As a result of comparisons between the tactile sense through haptic characteristics and through touching, it was observed that regarding density and thickness, tactile sense experience led to greater perceived reality, while this was not the case for elasticity.

Immersive Virtual Environment Technology (IVET) has emerged as a relevant technology in the marketing environment, with increased use in the retail context (O’Brien, 2016). As its use increases, there is a need to better understand its impact on consumer behavior and the experience that it delivers. Therefore, this study proposes a research model that captures the key constructs in understanding consumer acceptance behavior of the innovative technology used in marketing and how it impacts the brand experience. The objective of this study is to examine 1) antecedents (i.e., message fit and personal innovativeness) that may impact user’s attitude toward the IVET advertisement and self-image congruence, and 2) the transfer of positive or negative IVET advertisement attitude to behavioral intention. Survey was distributed at a large Southern university in USA. Out of 213 survey completed, 143 was usable. Hypotheses were tested using the structural equation model (SEM) analysis with maximum likelihood method (AMOS 23). The results showed that message fit had no significant impact on ad attitude and self-image congruence. Personal innovativeness had positive impact on ad attitude, but not on self-image congruence. Ad attitude had no effect on self-image congruence while having significant positive impact on offline store and online store visit intentions. Lastly, self-image congruence influences both offline and online store visit intentions. The results demonstrate that evaluation of the virtual world brand experience (i.e., attitude toward the IVET advertisement) is a strong predictor of user behavior toward the brand. A consumer’s interactions with a brand in the virtual environment may provide important information about the consumer’s desire to develop a relationship with the brand in other marketing channels, and serves as an opportunity for the marketer to assist in the buying process. Further, personal characteristic such as personal innovativeness may have a significant impact on a their attitude toward the IVET marketing which further leads to consumer’s decision to visit the online and offline store. In addition, self-image congruence were found to positively affect user’s intention to visit the stores, such that consumers who perceive their brand experience as more consistent with their self-image are more likely to consider purchasing the brand in the real world. The results suggest that some consumers may tend to behave in ways that are congruent with their self-identity across marketing channels.

This research examined the effects of learning on driving simulation game in virtual reality environment. We tested the difference of presence and learning effects such as learning persistence and learning transfer between general monitor and 3D virtual reality device, Oculus Rift by playtesting experiment. One hundred drivers with a license participated in the experiment of two modes of gaming environment. As a result, the user’s presence was found to be significantly higher in VR than general monitor game. As functional effects of the driving serious game, learning persistence and transfer of learning showed significant differences between two modes. This study validates the effects of virtual reality on learning, as an aspect of serious game function. The results contributes to theoretical and practical application of virtual reality in interactive serious games in the future.

The aim of this study is to verify the effects of user experiences such as present, flow and arousal between game play under 3D virtual environment(VE) and general video game play. For this purpose, Oculus Rift play test experimental treatment methodology was adapted for analysis. As a result, for the present hypothesis between the VE game and general video game, cognitive and present hypotheses were all adopted except for emotional presence, and there was no difference in arousal effect. And, VE game had significant differences in emotional presence, flow concentration effect, flow merging action & awareness and arousal effect compared with general video game. As the study verified that VE game had higher effect in presence effect, sense of realism and user experience of players than general video games through experimental studies, it contributes to elaborate 3D virtual environment game interface design and user experience study.

Malaysia is currently implementing the use of the Frog Virtual Learning Environment (VLE) in all government schools in the country. This paper outlines the basis for introducing the VLE in leveraging teaching and learning in Malaysian schools. It discusses the state of current literature associated with the use of VLE. In addition, it articulates the need for programme evaluation as a means for decision-makers to plan and take necessary corrective action to better implement VLE among teachers and students in schools. To sustain the implementation of this endeavour, a monitoring and evaluation mechanism must be put in place. This would determine how the VLE is performing and ascertain key success factors with the use of the Frog VLE among teachers and students. For this purpose, a survey research was undertaken using a sample comprising 426 teachers and 223 students from primary and secondary schools throughout the country. Reliability computations show Cronbach alpha values greater than .90 for the various constructs in the scaled items of the teachers’ and students’ questionnaires. The key findings of the study show significantly different perceptions (p < .05) in the use of Frog VLE as a learning tool between primary pupils and secondary students with significantly higher perceptions from secondary students on all aspects ranging from ease of use of Frog VLE to using Frog VLE as a collaborative tool for interaction within and outside the classroom. Factor analysis via the Principal Component Analysis method shows 3 critical success factors cited by teachers in the use of Frog VLE. The first factor concerns the functionality of VLE as a pedagogical tool; the second is associated with the user-friendliness of the VLE; and the third concerns the VLE as a tool for collaboration. An analysis of ranks derived from the mean computations of the variables within the first factor shows the VLE provides a platform for teachers to share ideas and opinions being ranked first. This is followed by VLE being used by students to obtain learning materials, which is ranked second. Third, the VLE being used by teachers to source for new teaching materials. Other major findings include issues associated with slow and unstable internet connectivity where secondary schools fared worse compared to primary schools and that rural schools tended to have more problems in connectivity as compared to urban schools. This paper puts forth a proposition that educational technology needs continuous monitoring and evaluation and effective change management is imperative to attain success in its implementation.

G-러닝은 게임기술과 게임이론을 바탕으로 교육용 콘텐츠를 개발하고, 개발된 콘텐츠를 사용자들이 사용하면서 학습하는 것을 말하며, 게임 시장의 유망한 분야로 널리 연구되고 있다. 하지만 현재까지 나온 대부분의 G러닝 콘텐츠는 학습적인 요소들만을 강조하고, 제작하는데 에 많은 어려움을 있기 때문에 사용자들이 재미가 떨어지고, 궁극적으로 교육적인 효과까지 떨어지는 문제가 있다. 본 논문에서는 이러한 G러닝 콘텐츠를 사용하는 사용자들이 재미와 교육적인 효과를 모두 얻을 수 있도록 가상 애니메이션 장르인 머시니마 기술을 사용하였다. 제안된 시스템은 사용자들이 G러닝 콘텐츠를 머시니마 기법을 사용하여 쉽게 제작하고, 제작된 콘텐츠가 사용자들의 커뮤니티에 의해서 확대 및 재생산 되도록 함으로써, 사용자들의 참여를 유도 하였다. 제안된 시스템은 RPG 게임에 나오는 요소들을 이용하여 블록 맞추기 및 최소 거리 찾기 등의 문제를 해결해 나가는 교육요소를 적용하였다.

본 연구에서는 다양한 색채환경에 대한 반응을 파악하기 위해 3차원 가상환경 인터페이스를 개발하고, 개발된 인터페이스에 대해 사용자가 어떻게 감성적으로 인터렉션하는지를 평가하였다. 3차원 가상환경은 후면 투사형 대형화면을 통해 제시되었으며, 가구를 포함한 실내 환경요소에 12가지 색채조합을 적용한 후, 피실험자들에게 색채조합에 대한 반응과 아울러 가상환경 인터페이스를 통한 감성적 인터렉션을 함께 평가하도록 하였다. 총 34명의 대학생들이 실험에 참여하였으며, 피실험자들은 대형화면 (8'×6')에 제시되는 고화질의 색채 환경 속에서 표준 입력장치를 사용하여 360도로 시선을 움직일 수 있었다.

본 논문은 3D 가상공간상에서 농촌에서 경험할 수 있는 작물재배, 가축사육 등을 가상 체험 할 수 있는 환경을 제공하여, 사용자에게 주말농장 체험과 유사한 경험을 할 수 있도록 한다. 기존의 웹 형태의 온라인 농작물재배/축산물 사육 시뮬레이션에서는 각종 텍스트 문서에 정지화상(사진이미지)을 적절히 조합하여 보여주는 형태가 대부분이며, 동영상으로 되어있는 내용들도 고정적인 이미지를 통한 정보습득 및 학습하는 형태로 되어있는데, 사용자들은 이 내용들보다 더욱 상세하고 많은 내용들을 필요로 하는 실정이다. 본 논문은 3D그래픽과 다중접속 네트워크 기술로 현실감 있는 가상의 농장 환경을 제공하여, 작물재배와 같은 기초적인 부분부터, 토지 환경 등을 간단하고 직관적인 인터페이스로 쉽게 접근할 수 있는 시뮬레이션 환경을 제공하며 농작물 재배가 실제 환경과 유사하도록 시뮬레이션 엔진을 구성하였다. 본 논문에서 구현된 시스템은 농업 교육이라는 건전한 놀이문화를 제공하고, 지방자치단체에서 시행하는 귀농 정책과 연계하여 시너지 효과를 가지며, 교육기관과 연계하여 작물 재배에 관한 학습 교재로서 기능을 가진다

본 연구에서는 교양지구과학과목을 수강하는 36명의 예비과학교사를 대상으로 가상현실(VR)의 사용을 한 차시에 걸쳐 시도하였다. 수업을 하기 전과 후에 구성주의 학습환경 조사(CLES)를 실시하였다. CLES의 주된 초점은 수업이 학생중심 수업환경을 얼마나 잘 보조하고 지원하는가다. 학생의 자신의 수업환경에 대한 사전 및 사후검사는 여섯가지 하위 영역으로 나뉜다.: 학생적절성, 비판적 시각, 교실통제의 나눔, 학생 간의 타협, 과학적 불확정성, 태도이다. 아울러 가상현실에 대한 미래교사의 인식에 대한 설문지도 실시하였다. 미래의 과학교사들이 가상현실 자료를 교실에서 사용하는 것에 대하여 어떻게 생각하는가를 본 연구를 통해 알아보고자 했다. 이들 결과를 바탕으로 교사 주도의 수업환경을 학생의 적극적 참여를 유도하는 수업에로의 변화를 도모하는 것과 같은 기존에 연구되지 않은 측면을 제안하여가상현실의 잠재력에 대한 보다 완벽한 이해를 꾀하려 하였다.

본 논문에서는 가상환경하에서 사용자가 느끼는 물체의 무게감에 관해 연구하며, 3D mouse에 스프링의 탄성력을 이용한 근력입력장치를 새롭게 디자인한다. 근력입력장치는 몰입형 가상환경에서 사용자들의 악력을 이용하여 힘이나 무게를 느낄 수 있도록 고안된 장비이다. 본 논문에서는 물체의 부피와 무게감에 관한 실험, 물체의 재질과 무게감에 관한 실험, 근력입력장치의 악력과 무게감에 관한 실험 등 세 가지 실험을 수행하여 비교·분석한다. 실험결과의 통계적 분석 및 사용자 설문지 분석을 통해서 얻은 결론은 몰입형 가상환경하에서 부피와 재질은 사용자들에게 현실감 있는 무게감을 느끼는 데 중요한 역할을 하지 못하지만, 근력입력장치의 악력을 사용할 경우 현실감을 증대시키며 무게감을 느끼는 데 중요한 역할을 한다. 본 연구에서 제안한 근력입력장치는 무게감을 제공하는 데 효과적이다.
