Alongside the development of communication technologies such as smart phone, 5G, advertisements which have been regarded as nexus of marketing behaviors are treated as surplus entities in our society now. Ad marketers have been focusing on storytelling advertisements via SNS or similar web-services. We are facing another big media changes such as Virtual Reality, Augmented Reality. Especially the current study probes Mixed Reality as the potential key of new storytelling brand marketing with discussing directions and insights based on the narrative transportation theory.

뉴스와 같은 정확한 정보를 제공하는 영상을 제작하는 과정은 많은 자원과 시간이 소요된다. 작성된 기사를 이용하더라도 영상 기반의 뉴스를 제작하는 것은 인적, 시간적인 자원의 투여가 불가피하다. 뉴스를 송출하기 위해 소요되는 시간을 줄이기에 현실적으로 어렵다. 따라서 우리는 이러한 문제를 해결하고 빠른 뉴스 영상 제공이 가능한 "뉴스 영상 생성 AI"를 개발하기로 하였다.

가상 피팅은 옷의 구매에 긍정적인 영향을 미치는 요소이다. 하지만 아직까지 여러 문제가 있어서 상용화가 되기 힘든 현실이다. 이러한 문제들 중에서 우리가 초점을 맞춘 것은 자연스러운 주름의 표현이다. 시간적 특성을 이용해 옷의 움직임을 자연스럽게 하고, 옷의 데이터를 얻어서 그 데이터로 옷의 주름표현과 텍스처 표현을 자연스럽게 할 수 있을 것이다.

In this paper, we review relevant technologies of Mixed Reality(MR) and show important components of perspective that can overcome technical limitations of the current MR. An MR technology combines real and virtual objects in a real environment, and runs interactive in real time, and is regarded as an emerging technology in a large part of the future of Information Technology(IT). We've grouped the major obstacles limiting the wider use of MR technologies into three themes: technological limitations (i,e., tracking, rendering, authoring, and registration), user interface(UI) limitations(i.e., UI metaphor for MR interaction), and social acceptance issues.

AR(Augmented Reality) technology is now easily shown around us with respect to its applicable areas' being spreaded into various shapes since the usage is simply generalized and many-sided. Currently existing camera vision based AR used marker based methods rather than using real world's informations. For the marker based AR technology, there are limitations on applicable areas and its environmental properties that a user could immerse into the usage of application program. In this paper, we proposed a novel AR method which users could recognize objects from the real world's data and the related 3-dimensional contents are also displayed. Those are done using image processing skills and a smart mobile embedded camera for terminal based AR implementations without any markers. Object recognition is done from the comparison of pre-registered and referenced images. In this process, we tried to minimize the amount of computations of similarity measurements for improving working speed by considering features of smart mobile devices. Additionally, the proposed method is designed to perform reciprocal interactions through touch events using smart mobile devices after the 3-dimensional contents are displayed on the screen. Since then, a user is able to acquire object related informations through a web browser with respect to the user's choice. With the system described in this paper, we analyzed and compared a degree of object recognition, working speed, recognition error for functional differences to the existing AR technologies. The experimental results are presented and verified in smart mobile environments to be considered as an alternate and appropriate AR technology.

The virtual reality technology is currently used classifying functional types such as the observation operation type, the experimental activity type, the learning information type, the field problem-solving type, and other different types, based on the media's characteristics implementing 3D form of multi-sensory information. Using Virtual Reality, the restoration of the 'Doksu Palace' has been grafted onto J. Keller's ARCS model, suggesting a field restoration concept that reenacts the lives of the people that had been in the field with the cultural heritage and history based on a scenario based scene direction. This paper also summarizes 3 different types of implementation of the field restoration assorting multi-scene direction. Certain limitations exist, due to the fact that a completed prototype hasn't been suggested and that a detailed notion of the housing and 3D audio connection has been omitted.

Since it is difficult for individual power producers and non-professionals who lack basic knowledge to control, manage, and operate facilities through EMS (Energy Management System), augmented reality and virtual reality monitoring systems are applied. However, in the existing systems, data access efficiency is inferior due to the process of analyzing column values for analog signal values collected from sensors and converting data after combining the columns. In addition, high-speed operation processing is difficult due to a large number of indexes for accommodating access patterns for various analog signal waveforms. Therefore, in this paper, a bitmap generator is inserted into a non-tree structure to convert the data collected from power facilities into physical property information, and the converted information is encrypted with a common key, so that the resources for the resources shared between each device are We propose a method of exchanging data for an augmented reality-based power system that is controlled by measurement.

With the development of computer technology, augmented reality (Augmented Reality, AR) technology in the future, one of the main directions of development of human interface technology is emerging. On augmented reality based on the design and implementation of a digital business card system. In this paper, a Smartphone is simply information through recognizable digital business card contains information about the system. Digital business card system is compared to the way existing hardware in a way visually-based high precision. In addition, registered as a 3D computer vision of augmented reality technology skills and real-world situations convergence technology for research. Future research, 3D electronic map for Smartphone apps as of the application user interface on the side for research is needed.
