Today, the incidence of illnesses due to a lack of exercise, such as lack of exercise in the 20s and 30s, 40s menstrual period, and 50s in the fifties, is increasing every year, because of the introduction of new technologies such as smartphone development,And the pattern of life according to it changes conveniently and the amount of activity decreases, and the lack of momentum has a great influence. I would like to study new mixed reality healthcare service products by merging the existing human smartphone with mixed reality. This is not merely showing the numerical value of the momentum by attaching to the human body like the existing healthcare product,And to measure and analyze the amount of exercise to help people to manage their health.

Digital media technology has power of influence as extended in not only science and technology but also our society and culture. These phenomenon is explained as 'digital convergence'. Edmond Couchot argue the term 'hybridization'. Yvonne Spielmann and Jay David Bolter also argue that digital hybrid artworks across and integrates a diverse range of modes of representation, such as image, text, sound, space and bodily modes of expression. They must also address communicative interaction in the convergence of real and virtual spaces. In this paper, I noticed mixed reality environment which is seen as the form of hybrid between real and virtual object. And I discuss about this phenomenon as the study of interdisciplinary between art and science.

This study applied virtual reality to women health nursing practicum for nursing students and analyzed the educational effect on meta-cognition and critical thinking. The study design was a convergent mixed method using single-group pre-post test design and individual in-depth interviews. After applying the virtual reality program, the post-score (104.16±12.98) was statistically significantly higher than the pre-score (98.59±18.09) (t=1.85, p=.030). There was no statistically significant difference in critical thinking after the program, with the post-score of 101.66±7.18 and the pre-score of 99.18±15.13 (t=1.00, p=.108). Therefore, women health nursing practice education using virtual reality can help improve the meta-cognition of nursing students.

최근 지구 온난화 효과에 의한 기상이변으로 기상정보에 대한 관심이 급증하고 있다. 날씨 예보가 일반인들의 일상생활에 영향을 미칠 뿐만 아니라 산업과 경제 전반에 미치는 영향이 크기 때문이다. 기상분야의 의사결정은 직간접적으로 많은 양의 자료를 필요로 한다. 기상자료로부터 공간에 관련된 지도 자료, 각종 측정 및 계측자료 등이 그것들이다. 따라서 기상분야에서의 의사결정이 앞에 나열한 자료를 처리하고 계산과정을 거쳐 그 결과를 바탕으로 이루어질 때 적절하고 합리적인 의사결정이라고 할 수 있을 것이다. 이러한 의사결정 시스템은 사용자가 직관적이고 종합적으로 의사를 결정할 수 있도록 여러 가지 복잡한 자료를 표출할 수 있어야 한다. 본 논문에서는 의사결정을 위한 기상가시화 시스템의 요구조건을 분석하고 설계를 제안한다.

디지털 기술의 발전에 따라 메타버스가 콘텐츠 시장의 주요 트렌드로 자리하면서 고품질의 3D 모델을 생성하는 기술에 대한 수요가 급증하고 있으며, 최근 메타버스를 필두로 하여 혼합현실 서비스 및 콘텐츠 시장이 활성화되면서 디지털 휴먼으로 대표되는 고품질 3D 가상 인간에 대한 제작과 관련된 다양한 기술적 발전이 급격히 가속화되고 있다. 본 고에서는 정밀한 3D 인체모형을 생성할 수 있는 기술들의 현재 상황과 기술적 사례들을 바탕으로 구성하고자 한다. 1996년 최초의 가상 인간의 등장 이후 가상 인간을 통한 다양한 시도가 이루어져 왔으나 기술적 한계로 그 영향력을 발휘하지 못하였다. 그러나 최근 기술의 발전을 통해 가상 인간은 디지털 휴먼으로 다시 등장하게 되었다. 디지털 휴먼은 실제와 구분하기 어려울 정도로 인간의 모습과 행동이 유사한 3D 가상 인간이다. 최근 기술의 발전은 이러한 가상 인간의 제작을 용이하게 만들었고, 이들을 다양한 분야에서 활용할 수 있게 하고 있다. 그러나 다양한 활용 분야와 수요에도 불구하고 현실적인 제작 과정상의 한계로 인하여 아직까지는 디지털 휴먼의 개발과 사용의 범위가 제한되고 있다. 이에 따라 본 고에서는 디지털 휴먼에 대한 선행연구의 분석을 통해 디지털 휴먼을 다시 한번 정의하였고, 제작 기법에 대한 연구를 바탕으로 현재의 기술적 한계를 극복하고 혼합현실 환경에 적용할 수 있는 발전된 형태의 디지털 휴먼의 제작을 위한 가능성을 살펴보고자 한다.

Space planning is one of the popular applications of VR technology including interior design, architecture design, and factory layout. In order to provide easier methods to accommodate physical objects into virtual space planning task, we suggest applying mixed reality (MR) interface. We describe our hardware and software of our MR system designed according to requirements of the application domain. In brief, our system hardware consists of a video see-through display with a touch screen interface, mounted on a mobile platform, and we use screen space 3D manipulations to arrange virtual objects within the MR scene. Investigating the interface with our prototype implementation, we are convinced that our system will help users to design spaces in more easy and effective way.

Natural synthesis of real and virtual images is a key technology in mixed reality. For this purpose, we propose an efficient dense disparity estimation algorithm and a synthesis algorithm considering features of stereo images. Dense disparities are estimated hierarchically from the low to high resolution images. In the process, the region-dividing-bidirectional-matching algorithm makes matching process efficient and keeps the reliability of the estimated disparities, and dense disparities are assigned considering edge information. finally, mixed reality stereo images are synthesized by comparing depth data of real and virtual Images. Computer simulation shows that the proposed algorithms estimate very stable disparity vectors with sharp edge and synthesize natural stereo mixed reality images.

This paper presents a design of a situation training system supporting mixed-reality for the developmental disabled. The training scenario is developed for the disabled to improve the sense of sight and perception. The user sticks a virtual pin into a hole in the working board according to the direction and the appropriate feedback is delivered based on the FSM(Finite State Machine). In order to improve the reality and the training effect, the user's hand is inserted in the virtual training environments and the tactile sensation is provided using the haptic device.

The educational benefits and potential of XR as a new medium are well recognized. However, there are still limitations in understanding the specific effects of XR compared to the more widely utilized representation of images on computer monitors. This study therefore aims to demonstrate the differences in effectiveness between the two technologies and to draw implications from a cognitive comparison of three-dimensional objects represented on a flat surface and virtually. The study was conducted a quantitative research method with an experiment involving two independent groups, and the results were tested using regression analysis. The results showed that for low-level, two-dimensional objects, the computer monitor method may be more effective, but above a certain level of complexity, the effectiveness of learning through the monitor tends to decrease rapidly. On the other hand, the group that used extended reality technology showed relatively high comprehension compared to the monitor group even as the complexity increased, and in particular, unlike the monitor group's rapidly decreasing comprehension level, the extended reality technology group showed a trend of decreasing comprehension with the level of complexity, suggesting the potential for compatibility and predictability in the use of technology.
