In order to realize the virtual prototyping (VP) of digital products, it is important to provide the people involved in product development with the appropriate visualization and interaction of the products, and the vivid simulation of user interface (UI) behaviors in an interactive 3D virtual environment. In this paper, we propose an approach to web-based 3D virtual experience using Unity and Leap Motion. We adopt Unity as an implementation platform which easily and rapidly implements the visualization of the products and the design and simulation of their UI behaviors, and allows remote users to get an easy access to the virtual environment. Additionally, we combine Leap Motion with Unity to embody natural and immersive interaction using the user's hand gesture. Based on the proposed approach, we have developed a testbed system for web-based 3D virtual experience and applied it for the design evaluation of various digital products. Button selection test was done to investigate the quality of the interaction using Leap Motion, and a preliminary user study was also performed to show the usefulness of the proposed approach.

Motivations to engage in internet shopping as well as traditional off-line shopping include both utilitarian and hedonic dimensions. It is important that online fashion retailers offer the sense of the real shopping experience that offline fashion retailers do. This article is to assess empirically virtual model impact on consumer's online shopping experience. To test hypothesis, an experiment was executed a field study on foreign internet shopping(www.landsend.com). Prior to administering the experiment, a pilot test was conduct among 20 undergraduate students to pre-test for computer system trouble and delay problem. The experiment was conducted to 90 studetns. The participants were instructed to answer all the questons based on their experience when using that particular internet shopping mall. The LISREL 8.50 was used for statistical analysis. The results indicate that the virtual model characteristics such as vividness, customization, and interactivity are important factors in affecting consumer's shopping experience. Online shopping experience have a strong positive effect on shopping mall loyalty.

VR and AR are widely used in many applications to provide more immersive visualization and natural interaction for learning and experiencing virtual but realistic tasks. Energy saving is considered as one of the most important issues throughout the world in order to overcome global warming and energy crisis. In particular, the awareness of home energy saving is regarded as a first step to deal with this issue. In this paper, we suggest a new learning environment using virtual and augmented reality (VR/AR) for home energy saving experience. In particular, it presents a comparative study of the user experience in home energy awareness using immersive virtual reality and mobile augmented reality. The first person user experience using immersive VR wearing head mounted display (HMD) and the third person user experience using mobile AR are implemented and systematically compared with each other in terms of the learning effect of energy saving and qualitative usability. Implementation results will be given to show the advantage and effectiveness of the proposed approach.

The essence of fashion brands' marketing with metaverse-based virtual spaces is to capture more potential consumers and boost the sales of companies' virtual and physical products. However, existing research has not fully addressed customer responses and behavioral outcomes regarding fashion virtual brand spaces. This study uses flow theory to address this gap and explores the factors that lead to the flow experience in virtual brand spaces. It also establishes the causal relationships between the flow experience, satisfaction with virtual spaces, the intention to purchase virtual products, and the intention to purchase actual products. We chose "Ralph Lauren World" of Ralph Lauren on Zepeto as the virtual brand space for this study and analyzed 239 valid data sets. We tested the hypotheses using structural equation modeling and bootstrapping for the mediation analyses. The findings indicate that the flow experience in virtual brand spaces positively and indirectly affects the purchase intention of virtual products via satisfaction with virtual brand spaces. In addition, virtual space satisfaction had an indirect, positive effect on actual product purchase intention through virtual product purchase intention. The research emphasizes that the purchase intention of virtual and actual products has a positive causal relationship.

This study is based on place attachment theory, explores how to transform tourists' virtual experience into on-site tourism willingness through virtual attachment, And explores the moderating role of happiness in it. A real travel intention model is constructed for people who work in tourism or have the ability to travel alone. Analyzed through analysis tools such as SPSS and AMOS, We hope to explore if the virtual experience can be transformed into a willingness to travel on the ground, and how happiness moderates virtual attachment to virtual tourism experiences. The result shows, the relationship between Virtual Travel Experience and Virtual Attachment is moderated by Happiness, Virtual Attachment is positively related to Place Attachment (Place dependence & Place identity), Place Attachment is positively related to Real Travel Intention. The relationship between tourists and tourist destinations is explored in depth through this study to provide references and suggestions for tourism development.

A virtual reality is a virtual space constructed by a computer that provides users the opportunity to indirectly experience a situation they have not experienced in real life through the realization of information for virtual environments. Various studies have been conducted to realize virtual reality, in which the user interface is a major factor in maximizing the sense of immersion and usability. However, most existing methods have disadvantages, such as costliness or being limited to the physical activity of the user due to the use of special devices attached to the user's body. This paper proposes a new type of interface that enables the user to apply their intentions and actions to the virtual space directly without special devices, and test content is introduced using the new system. Users can interact with the virtual space by throwing an object in the space; to do this, moving object detectors are produced using infrared sensors. In addition, the users can control the virtual space with their own postures. The method can heighten interest and concentration, increasing the sense of reality and immersion and maximizing user's physical experiences.

In this paper, we propose spatial information based simulator for user experience optimization and minimize real space complexity. We focus on developing simulator how to design virtual space model and to implement virtual character using real space data. Especially, we use expanded events-driven inference model for SVM based on machine learning. Our simulator is capable of feature selection by k-fold cross validation method for optimization of data learning. This strategy efficiently throughput of executing inference of user behavior feature by virtual space model. Thus, we aim to develop the user experience optimization system for people to facilitate mapping as the first step toward to daily life data inference. Methodologically, we focus on user behavior and space modeling for implement virtual space.

In recent years, various virtual reality contents have been explosively developed, and the 'chance operation' in previous studies was mentioned. This study tries to implement the Step Sequencer in the virtual reality. Through the theoretical background analysis and case studies of virtual reality, three major experiential values such as Value of Overcoming Constraints, Value of Strengthening Experience, and Value of Creating New Experience were induced. A convergencestep sequencer with the presence and immersion elements was developed and presented so that the music contents divided into 4 areas can be understood easily controlled more conveniently while keeping the identity of the step sequencer. It is expected that various convergence VR contentscan be developed in the future studies.

This study confirms how brand experiences perceived by consumers in the metaverse affect their pleasure and behavioral intentions (intention to use the platform, and purchase the virtual product). The results of this study are as follows. First, consumers have sensory, affective, behavioral, and intellectual experiences while interacting with fashion brands in the virtual space of the metaverse. Second, in the metaverse, consumers experience pleasure when they have various brand experiences including those mentioned above. Third, the pleasure gained through consumers' brand experiences has a positive effect on their behavioral intentions, including their intentions to use the platform and purchase the virtual product in the metaverse. This study is academically meaningful in strengthening brand experience-related research and expanding into the metaverse context through empirically verifying the influence of consumers' brand experiences on pleasure in the metaverse. Also, related fashion companies will be able to use the results of this study to strategically create consumers' sensory, affective, behavioral, and intellectual experiences to elicit pleasant emotions from consumers in the virtual space of the metaverse.
