“…In Sampaio and Martins (2014) the application of VR to visualize the construction of a bridge using two different construction methods is described. The target of this implementation was to give students a deeper understanding about how bridges are built, as they can't have the same level of insight on a real construction site due to safety reasons.…”

Background: Presenting significant building or engineering 3D-models is a crucial part of the planning, construction and maintenance phases in terms of collaboration and understanding. Especially in complex or largescale models, immersion is one of the major key factors for being able to intuitively perceive all aspects of the scene. A fully immersive system needs to give the user a large field-of-view with reduced latency for lifelike impression. Technologies such as VRwalls and shutter glasses can deliver high refresh rates, yet fail to give a large field-of-view. Head-mounted-devices for virtual reality fill this gap. Head tracking mechanisms translate movements of the user's head into virtual camera movements and enable a natural way of examining models. Unlike a stereoscopic representation with projectors, point-of-view tracking can be achieved separately for each individual user. Hardware costs for such systems were very high in the past, but have dropped due to virtual reality systems now gaining traction in the mainstream gaming community. Methods: In this paper we present a way to build a low-cost, highly immersive virtual reality environment for engineering and construction applications. Furthermore, we present a method to simplify and partly automate the process of reusing digital building models, which are already used in construction, to create virtual scenes, instead of having to do parallel content creation for visualization. Using the Oculus Rift head-mounted display and the Leap Motion hand-tracking device, we show the possibilities of naturally interacting within a virtual space in different use cases. The software, based on the popular game engine Unreal Engine 4, will be used as a basis for further research and development. Results: Building Information Modeling data can be imported to UE4 with our presented plugin. Using an automated database for mapping materials to the geometry simplifies the process of importing Building Information Modeling entities. The refresh rate of the system stays within acceptable margins needed for virtual reality applications using head-mounted devices. Conclusions: Head-mounted devices present a great potential for the Architecture, Engineering and Construction industry, as a person can experience realistic first-person situations without having to care about injuries. Automated processes for the simplification of content creation, leveraging existing models, and the usage of visual programming languages enable even nonprogrammers to create scenarios to their needs.

“…Its essence is to provide an advanced technology of man-machine interface. It is in an analog mode for the user to create a real-time interaction with physical objects reflect changes in the three-dimensional image of the world, in lifelike experience vision, hearing, touch, smell and other acts of perception, so that the participants can directly participate and explore virtual objects and changes in the role of the environment, like being in the real world [4][5]. The architecture is shown in figure 1.…”

“…It is difficult to prepare a real environment that provides the same conditions as the presentation environment. Virtual reality (VR) solves this problem by providing a useful and immersive training environment that includes real-life conditions for individuals [7]. Therefore, people can develop themselves and gain experience by training in the virtual environment designed similar to a real experience [8].…”

Abstract. Public speaking anxiety is a type of social phobia, which might be commonly seen in novice software engineers. It is usually triggered by a fear of social performance especially when the performer is unfamiliar with the audience. Today, many software engineering activities (e.g. code inspection, peer review, daily meetings, etc.) require social gatherings where individuals need to present their work. However, novice software engineers may not be able to reduce their performance anxiety during their course of education. In this study, we propose a virtual reality approach to construct a practice environment for improving novice software engineers' pubic speaking experiences. Consequently, we examine the effects of virtual reality intervention on the public speaking experience of six novice software engineers from a computer engineering department. We designed a virtual auditorium to simulate the presentation delivery environment and findings suggest that using this infrastructre for training purposes can reduce presenter anxiety levels which is consistent with related published studies. We believe that this virtual auditorium environment can deliver benefits for students and practitioners alike in terms of addressing the anxiety that is often associated with early stage career presenters.
