Augmented reality is a novel human-machine interaction that overlays virtual computer-generated information on a real world environment. It has found good potential applications in many fields, such as training, surgery, entertainment, maintenance, assembly, product design and other manufacturing operations. In this study, a smartphone-based augmented reality system was developed for the purpose of monitoring and managing injection molding production lines. Required management items were drawn from a management content analysis, and then the items were divided into two broad management categories: line management and equipment management. Effective work management was enabled by providing those working on the shop floor with management content information combined with the actual images of an injection molding production line through augmented reality.

This study examines the effect of congruity between product and TV reality show on purchase intention of Chinese consumers. A total of 110 respondents from Chinese consumers were collected using online surveys. The results were analyzed by SPSS 22.0. Multiple Linear Regression and process analysis were used to test the hypotheses. This article found that congruity between product and TV reality show, attitude toward product placement and recall of product affected consumers' purchase intention. In addition, the frequency of consumer watching TV reality show and familiarity of product moderated the attitude toward product placement and recall of product. This study provides useful implications for sponsors to select product placement as one of their marketing promotion tool.

Recently, peoples are suffering from various psychological disorders such as addiction, phobia, depression, and bipolar disorder. Moreover, children with ADD/ADHD and autism are increasing. Korean tends to regard the psychological disorders as taboo. Therefore, it is unusual case that the mental patient gets the psychological therapy. Virtual reality has come to the spotlight as a useful tool for the therapy due to its anonymity and easy accessibility. The therapy in the virtual reality is called cyber-therapy. Emotion of the patient is important for the treating process. The objective of this paper is to review the researches on the treatment of psychological disorders using the virtual reality and prospect the affective interaction technology for the cyber-therapy.

Based on the theory of space perception, this paper concludes that the mixed reality application under the theory of space perception has a three-level definition of visual hierarchy and then analyzes the component elements of interface design and the classification mode of interface windows. Next, carry out case practice research through this theoretical definition, and finally conduct the survey and analysis of questionnaire data, verifying that the mixed reality interface design based on spatial perception theory meets the user experience elements of Usability, Availability, and Attraction. The conclusion is that the constituent elements of interface design and the window classification mode can provide specific and practical design specifications for mixed reality interface design, reduce the interaction cost of completing tasks, reduce users' cognitive load, and make it easier for users to receive interface information

Recent advances in Internet-of-Things and wearable computing have established computationally sufficient infrastructure to remove the barriers of physical locations. The recent COVID-19 pandemic has accelerated the use of remote collaboration, work-from-home, teleconferencing, online education, digital twin, and metaverse enriched with various configurations of augmented reality, virtual reality, mixed reality, and extended reality. Beyond specialized niche wearable applications in the medical and entertainment domains, we aim to identify the underlying characteristics of smartglass-enabled killer applications for everyday use. In this paper, we analyze intermediary roles in remote collaboration consisting of authoritative supervisors, synergetic collaborators, and speculative explorers. We also propose technical components for smartglass-assisted interactive remote collaboration composed of personal tracking, teleconference, and interaction components. More specifically, the application tasks of each intermediary role and objectives of three functional components are defined and elaborated.

Cyber Sickness, which occurs when using Virtual Reality contents, is the most serious problem in immersive Virtual Reality contents. The purpose of this study is to identify the effects and causes of graphic environmental factors on Cyber Sickness in Virtual Reality contents. To this end, cyber sickness experiments were conducted according to the light source and material settings, which are most commonly used in graphical environmental elements. Cyber Sickness measurements were based on the Simulator Sickness Question(SSQ) tool to derive an index that causes Cyber Sickness As a result of the analysis, the smaller the surface roughness, the higher the degree of Cyber Sickness, and the smaller the surface roughness, the smoother the surface of the 3D object, and many specular reflections from the light source occurred, which was confirmed to be the cause of great Cyber Sickness.

본 연구에서는 한옥의 해석모델 구축을 지원하고, 구축된 해석모델의 활용도를 높이고자 이를 활용한 가상현실 소프트웨어를 개발하였다. 한옥의 구조해석 모델은 범용 구조해석 소프트웨어인 midas Gen으로 생성하고, 이를 문자기반 입력파일로 변환한 후 본 연구에서 개발된 소프트웨어에서 한옥 해석모델의 검토에 필요한 자료들을 저장한다. 개발된 가상현실 소프트웨어 내에서 3차원으로 표현된 한옥의 해석모델은 시점을 변경하며 살펴볼 수 있고 특정 부재를 선택하여 관련된 자료를 확인할 수 있다. 이러한 과정을 통해 해석모델의 오류를 확인 및 수정하여 완결된 해석모델을 구축할 수 있다. 개발된 소프트웨어는 3개의 한옥 사례에 적용하여 그 적용성과 효용성을 검증하였으며, 구조분야 이외의 타 분야에서도 활용될 수 있다.
