  • IT기술의 발전에 따른 각종 산업에서의 유비쿼터스 도입이 이루어지고 있다 특히 자동차 산업에서 유비쿼터스 환경 도입을 위한 연구가 활발히 진행되고 있으며, BMW의 경우 유비쿼터스 환경 기반의 운전자지원시스템을 연구한바 있다. 조선산업에서 유비쿼터스 환경을 구축하고자 유비쿼터스 기반의 혼합현실을 제시한다. 혼합현실은 현실과 가상이 융합된 환경으로 현실에 기반을 두었을 때 증강현실이라고 하며, 이것은 현실세계에 가상의 물체를 오버랩하여 보여줌으로써 보다 현실감을 높여주는 기술이다. 따라서 본 논문에서는 해양구조물에서의 효과적인 검자 지원을 위하여 증강현실 기술을 활용하였으며 프로토 타입을 구축해 봄으로 그 활용 가능성을 판단해 보고자 한다.

  • K/DA는 게임 캐릭터를 기반으로 만들어진 K-pop 버추얼 아이돌이다. 이에 본 연구에서는 K/DA를 중심으로 버추얼 아이돌의 생성과정과 특징, 존재론적 의미를 파타피직스의 관점에서 분석했다. K/DA는 게임 캐릭터와 아이돌 걸그룹의 캐릭터 데이터베이스를 기반으로 생성됐다. 이때 가상의 아이돌 캐릭터와 실제의 여성 아이돌이 결합해 독자적 정체성을 구축한다. 이후 모션 캡처를 통해 가상화된 인물의 신체를 체화하고, 증강현실을 통해 무대에서 퍼포먼스를 구축한다. 그 결과 K/DA는 가상과 현실을 가로지르는 동시에, 둘 중 어디에도 귀속되지 않는 파타피지컬 주체가 된다. 이처럼 K/DA는 가상/현실, 정보/물질, 기계/인간을 구분했던 이분법적 체계를 극복하고, 향후 디지털 주체가 위치할 제3의 지대를 제시했다는 점에서 그 의의가 있다.

  • Digital media technology is gradually developing with the development of convergence quaternary industrial technology and mobile devices. The combination of deep learning and augmented reality can provide more convenient and lively services through the interaction of 3D virtual images with the real world. We combine deep learning-based pose prediction with augmented reality technology. We predict the eight vertices of the bounding box of the object in the image. Using the predicted eight vertices(x,y), eight vertices(x,y,z) of 3D mesh, and the intrinsic parameter of the smartphone camera, we compute the external parameters of the camera through the PnP algorithm. We calculate the distance to the object and the degree of rotation of the object using the external parameter and apply to AR content. Our method provides services in a web environment, making it highly accessible to users and easy to maintain the system. As we provide augmented reality services using consumers' smartphone cameras, we can apply them to various business fields.

  • 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.

  • Virtual manufacturing technology has been applied in actual production sites with the development of virtual reality technology. However, the current virtual manufacturing technology requires experts for application of the system. Furthermore, the sense of reality is diminished as the entire simulation is driven by virtual objects. In contrast, mixed reality can visualize virtual objects and an actual work place simultaneously, and thus the sense of reality of the virtual manufacturing simulation can be improved. This paper introduces a method that applies mixed reality in the manufacturing process, and proposes a method to adapt general safety sign post in the factory instead of a black square marker for visual fiducial recognition.

  • Augmented Reality (AR) is a useful technology for various industrial systems. This paper suggests a new playground system which uses markerless AR technology. We developed a virtual playground system that can learn physics and kinematics from the physical play of people. The virtual playground is a space in which real scenes and CG are mixed. As for the CG objects, physics of the real world is used. This is realized by a physics engine. Therefore it is necessary to analyze information from cameras, so that CG reflects the real world. Various games options are possible using real world images and physics simulation in the virtual playground. We think that the system is effective for education. Because CG behaves according to physics simulation, users can learn physics and kinematics from the system. We think that the system can take its place in the field of education through entertainment.

  • The popularity of Smartphones makes new fields of applications based on location based service easily feasible with a new user interface called augmented reality (AR). It presents a particularly powerful user interface to context-aware computing environments. AR on Smartphones integrates virtual information into a person's physical environment by overlaying information on an image taken through Smartphone's camera and motion sensors. Mobile augmented reality systems provide this service without constraining the individual's whereabouts to a specially equipped area. This work presents an overview of handheld augmented reality focusing on applications with introducing the basic issues of them. For this purpose, an example system, Studierstube ES (embedded system), is cited, which introduces the most significant problems and various methods of solving them through the experience of converting existing PC-based AR system into handheld AR.

  • Metaverse refers to a digitally expanded world by combining real and virtual spaces. As reality expands into the digital world, various things that were not possible before are possible with the aid of the system, and its usefulness is spreading metaverse rapidly regardless of industry. In particular, it is relatively easier to display information from the virtual world over the real world than to bring information from the real world into the virtual world, which is why most industries are pursuing a metaverse using AR(Augmented Reality). The construction industry also tried to introduce the AR metaverse except in certain fields such as education, but it is being used only limitedly due to the limitations of AR devices. The disadvantages of AR devices, which are sensitive to afterimage effects, narrow viewing angles, and environmental influences, are the main reasons that make AR challenging to use in actual workplaces, not only in the construction industry but also in other industries. So as the technological maturity of VR(Virtual Reality) devices increases, VR will gradually replace AR. Therefore, in response to future changes, the construction industry should plan metaverse technology development using VR devices.

  • 본 연구는 최근 건설분야에서 활용도가 높아지고 있는 증강현실 도구를 활용하여 학생들이 철근공사 배근작업을 학습할 수 있는 교육지원 컨텐츠를 개발하고 적용효과를 분석하였다. 구조도면에 대한 이해도를 높이기 위해 구조도면을 마커 이미지로 활용하였으며, 구조도면에 따라 배근된 가상의 3D 배근 모델을 화면에 겹쳐 표현하는 방식으로 증강현실을 구현하였다. 또한 3D 배근 모델과 함께 2D도면의 독도법, 이음 정착길이 기준, 부재별 구조설계기준에 따른 배근방법, 그리고 실제 배근하는 순서 등을 학습할 수 있도록 컨텐츠를 구성하였다. 적용결과 인터페이스 스타일, 지각된 유용성, 지각된 활용의 용이성, 지각된 즐거움, 활용 태도, 활용 의도 측면에서 긍정적으로 평가되었으며, 증강현실은 교육적 측면에서 시각화와 상호작용의 장점이 있기 때문에 활용가치가 높을 것으로 판단된다.
