This study classified sensory affordances, functional affordances, and perceptual affordances, and verified their effects on consumers' participation and intention to stay in the metaverse. As a result of the study, sensory affordance, functional affordance, and perceptual affordance all had a positive effect on consumer participation, and sensory affordance had the greatest effect. In addition, consumer participation was found to increase the intention to stay. Service companies that provide metaverse platforms will have to pay more attention to realizing virtual space through various senses and physical elements when building a metaverse in order to encourage customers to actively participate in the service process. Since services based on the 4th industry, the participation of consumers needs to be more actively reviewed. From the perspective of affordance, it is expected that the realistic implementation of the metaverse environment and the interaction with various contents or avatars in the space will increase consumer participation.

The technology of 'Virtual Reality' has placed in advanced tools for human beings' joy and anger together with sorrow and pleasure in our generation. It has recently tried in a variety ways to use as an implication for treatment in the field of Cognitive Psychology. Especially, it widely approaches to human in terms of that a sense of reality in a virtual world through the five senses should reinterpret the meaning of cognition in the real world. Based on this paradigm shift, it allows for new treatment using the technology of virtual reality. A typical example is a field of Therapy in order to overcome panic disorder. It has advantages that in particular development of flexible interaction technologies in a virtual space can lead patients to experience psychological environments rather than physical one. the interaction technology provides environments in which users' five senses can be actively stimulated, it is very useful that information from the experiences in the virtual world allows people to learn through real experiences by renewing potential energies, advantages of Virtual Reality Therapy can be customized treatment by depending on symptoms in patients with panic disorder and are capable of differentiate application for the cure at each stage. It is to treat by leading patients to get accustomed to environments and situations in real world through care process with each symptom and stage. It is helpful that based on A Human-Sensibility Ergonomics, technologies like immersive virtual reality equipment, force-relative feedback and stereophonic sound, and like stimulating the sense of smell make people to induce experiences by stimulating human's five senses. There are many advantages of immersion in virtual world in that the phenomenon such as challenge, interaction, reality, illusion, and cooperation is expanded. As an application for therapy by growing such augmented reality, virtual space and sharing of data through the Internet and also inexpensive its availability have recently expanded the base. There are other benefits of Virtual Reality Therapy offering active interaction environments for cognitive experience which can provide appropriately adjusted environments for patients who are hard to overcome the real situation because of phobia. In addition to that it is safe and economical and patients' confidentiality is assured. Moreover, due to the principles of applying real-time navigation the Virtual Reality Therapy makes modification and supplementation easier and also it can reduce cybersickness because of the supply of Lenticular allowing people to see stereoscopy without eyeglasses, which makes sense of presence clearer. On top of that due to the development of interactive technologies, it is becoming close to sense of reality similar to real world by leading users to navigate by themselves and to operate objects in a virtual space. This paper will therefore examine, although it is of limited, characteristics of application of virtual reality technology based on A Human-Sensibility Ergonomics used for treatment for a disorder. this paper will analyse a range of its application and problems and it will suggest the future possibilities.

This study is to examine the effects of gesture based interface and display methods to make an effective virtual learning environment. The gesture based interface can provide interactive interface to make objects in the virtual learning environment by generating natural movement of users' gesture. This natural functionality leads users to apply natural movements as they do in real actions. Because of the natural user interface, the gesture based interface is expected to maximize learning outcomes. This study examined how the gesture based interface can be used when a head mounted display is applied for a virtual reality learning environment. For this study 44 colleagues students were participated. Two display methods (head mounted display vs. monitor) and two interface (gesture based interface vs. joystick) were tested to identify which might be more effective. The study was applied to different learning tasks which require different levels of spatial perception. The dependent variables are three constructs of virtual presence (spatial perception, immersiveness, and realness) and task completion time and recall tests. This study discussed potential disadvantages of gesture based interface while it showed positive usages of gesture based interface.

The purpose of this study was to test a large screen and rear-projected virtual reality (VR) interface in color choice for environmental design. The study piloted a single three-dimensional model of a bedroom including furniture in different color combinations. Using a mouse with an $8'{\times}6'$ rear-projector screen, participants could move 360 degree motion in each room. The study used 34 college students who viewed and interacted with virtual rooms projected on a large screen, then filled out a survey. This study aimed to understand the interaction between the users and the VR interface through measurable dimensions of the interaction: interest and user perceptions of presence and emotion. Specifically, the study focused on spatial presence, topic involvement, and enjoyment. Findings should inform design researchers how empirical evidence involving environmental effects can be obtained using a VR interface and how users experience the interaction with the interface.

Collaboration has become essential in the product design process due to internationalized and specialized business environments. This study presents a real-time collaborative 3D design workspace for distributed designers, focusing on the development and the evaluation of new interaction techniques supporting nonverbal communication such as awareness of participants, shared manipulation and tele-presence. Requirements were identified in terms of shared objects, shared workspaces and awareness through literature reviews and an observational study. An Augmented Reality based collaborative design workspace was developed, in which two main interaction techniques, Turn-table and Virtual Shadow, were incorporated to support shared manipulation and tele-presence. Turn-table provides intuitive shared manipulation of 3D models and physical cues for awareness of remote participants. Virtual shadow supports natural and continuous awareness of location, gestures and pointing of partners. A lab-based evaluation was conducted and the results showed that interaction techniques effectively supported awareness of general pointing and facilitated discussion in 3D model reviews. The workspace and the interaction techniques can facilitate more natural communication and increase the efficiency of collaboration on virtual 3D models between distributed participants (designer-designer, engineer, or modeler) in collaborative design environments.

우리나라 교육통계에 따르면 외국인 가정 및 국제결혼 가정의 자녀 수는 138,227명에 달하며(교육부, 2020), 결혼이민자는 169,005명에 이른다(법무부, 2022). 이들 중 대다수는 의사소통의 어려움을 호소하며, 의사소통 문제는 학교 및 사회생활 부적응으로 이어진다. 이에 대하여, 지방자치단체와 다문화 유관기관 등에서 다양한 한국어교육 프로그램을 진행하고 있지만, 대부분이 단편적인 학습지 교육이나 문화 체험 수업에 그치거나 코로나19 등으로 인하여 수업이 중단되는 등 효과적이고 체계적인 교육이 제공되지 못하고 있는 실정이다. 본 연구에서는 한국에서 적응하고 생활해야 하는 다문화 가정 구성원들을 대상으로 한국어교육을 체계적으로 실시하기 위해 가상현실(VR)을 활용한 교육 프로그램을 제안한다. 이는 시공간의 제약을 받지 않아 일반 교재나 PC 활용 수업에 비해 접근성이 좋고 실재감과 몰입감을 높여 학습자의 흥미와 참여도를 향상시킬 수 있다. 특히 다자간 동시 참여가 가능한 메타버스 공간에서는 학습자 간 활발한 상호작용 및 소통이 가능하여 언어 능력과 더불어 사회 적응력을 기르는 데에 기여할 수 있다.
