Objective. Although cardiopulmonary resuscitation (CPR) skills are lifesaving skills, the gap between awareness and actual training remains significant. Advances in technology are shaping the future of education and innovative learning solutions are essential to facilitate effective and accessible training. This project objective is to develop a self-directed educational system for hands-on CPR training using virtual reality (VR) technology. Methods. HTC VIVE was the chosen VR engine, and Unity3D was the software used for development. CPR skills including chest compressions, rescue breathing, and automated external defibrillator (AED) are taught in VR through focused instructions, demonstrations, and simulated interactive scenarios with hands-on training sessions. A tracking system was designed using virtual planes and VIVE-Tracker for accurate measurements of chest compressions (rate, depth, and recoil), hands' position and AED. A real mannequin was integrated in the VR space and overlaid with virtual 3D-human model for realistic haptic

This article presents an application of Augmented Reality technology for interior design. Plus, an Educational Interior Design Project is reviewed. Along with the dramatic progress of digital technology, virtual information techniques are also required for architectural projects. Thus, the new technology of Augmented Reality offers many advantages for digital architectural design and construction fields. AR is also being considered as a new design approach for interior design. In an AR environment, the virtual furniture can be displayed and modified in real-time on the screen, allowing the user to have an interactive experience with the virtual furniture in a real-world environment.Here, AR environment is exploited as the new working environment for architects in architectural design works, and then they can do their work conveniently as such collaborative discussion through AR environment. Finally, this study proposes a new method for applying AR technology to interior design work, where a user can view virtual furniture and communicate with 3D virtual furniture data using a dynamic and flexible user interface. Plus, all the properties of the virtual furniture can be adjusted using occlusion-based interaction method for a Tangible Augmented Reality.

This article presents a study on Augmented Reality (AR) development as a new performance approach for collaborative space of urban design work. Here, the participants-e.g. architects, structure engineers, equipment vendors, etc-can view an urban design process through AR scenes by Head-Mounted Display (HMD) glasses. Nowadays, the AR technology has been supported as a great graphical computing technology which promises to offer several advantages of applying for the digital architecture and construction fields. The AR effects enable users to examine 3D project models integrated into real environment in an intuitive way and real-time. Therefore, this research focuses on an establishment a kind of smart AR discussion space-the Augmented Reality Conference Desk (named as ARCdesk for short). As the result, the participants can examine a planning process of urban design work in 3D/4D multi-phases by intuitive ways. In particular, all participants also can examine the digital urban mock-up from free views and they also can interact with whole models (or each part) during architectural discussion. As the novelty of research, the participants were suggested to manage and create the input digital urban models basing on use a range of available Google Earth facilities which are usability for architectural design, such as the Google SketchUp, Google Building Marker and Google 3D Warehouse. This example also involves the conceptual combination of AR and 4D construction simulation within indoor condition in order to simulate the phases such urban growing up. The implementation bases on the main technical theme: the imagery vision-based AR tracking and the Tangible Augmented Reality.

This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields.While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

This article examines the Augmented Reality (AR) development to become a new support for executing works in the construction worksite. In particular, the installing works of HVAC system after completion stage of masonry building (e.g. ventilator system, water and power supply, fire prevention system, et al) will be considered as the study subjects. In this work, the ventilator duct system will be operated in AR environment. The research proposes a new working manner by AR effects for technicians, and then establishes the AR system simultaneously. Actually, the proposed implementing process promises to be novelty and usability of research. Because the useful supports by AR technical can bridge the gap between desktop design documents and executing works in worksite that are enable to technicians (or workers) do their works in convenient environment. In implementing case, the technicians can check and do a comparison between the technical contents in design documents and virtual models of reality ventilator components in life position in worksite. In addition, they also can observe an AR animation guideline of assembling works in real-time. For technical issues, this work exploits an imagery marker-based AR tracking method in order to embed it into architecture works.
