The Impact

Construction 4.0 (a concept of Industry 4.0) is an ongoing transformation that aims at digitalization and automation of traditional construction and industrial practices using modern smart technology. The technological development especially of the construction sector is of utmost importance to meet the requirements of rapid construction projects aiming at quality work, increased productivity, and cost savings. One such technology that has come to the limelight is Virtual Reality (VR), which is a computer-generated smart environment that is artificially created using various types of hardware and software. This smart environment is created to resemble a real-life structure that can be explored, visualized, and interacted with by users using electronic devices for better decisionmaking before actual construction. The purpose of this paper is to design a Virtual Reality model using Building Information Modelling (BIM) and to examine the impact and influence of Virtual Reality Technology in the Indian construction industry with the help of a questionnaire survey. This study provides necessary information for implementing Virtual Reality technology in the construction industry. The results of this study provide a research road map to researchers for their future efforts.

<abstract> <p>The 5G virtual reality system needs to interact with the user to draw the scene in real time. The contradiction between the complexity of the scene model and the real-time interaction is the main problem in the operation of the virtual reality system. The model optimization strategy of architectural scene in virtual reality design is studied, and the method of architectural scene model optimization is summarized. This article aims to study the optimization of computer vision software modeling through 5G virtual reality technology. In this paper, the optimization of the architectural model is studied by the method of image gray scale transformation, computer vision detection technology and virtual modeling technology. The four experiments are comprehensive evaluation and quantitative evaluation, comparison of channel estimation performance of different pilot structures, comparison of calculated and true values of external azimuth elements, and the effect of window-to-wall ratio on energy consumption per unit of residential building. The results show that hollow bricks of building materials have a great impact on the environment. The values of the three pixel coordinates X, Y, and Z calculated by the unit quaternion method are 1.27, 1.3, and -6.11, respectively, while the actual coordinate positions are 1.25, 1.37, and -6.22, respectively. It can be seen that the outer orientation element value calculated by the quaternion-based spatial rear intersection method is not much different from the actual value, and the correct result can be accurately calculated.</p> </abstract>

<p class="3">Within a constructivist paradigm, the virtual reality technology focuses on the learner's actively interactive learning processes and attempts to reduce the gap between the learner’s knowledge and a real-life experience. Recently, virtual reality technologies have been developed for a wide range of applications in education, but further research is needed to establish appropriate and effective learning techniques and practices to motivate meaningful learning. Results showed that perceived self-efficacy and perceived interaction are two crucial factors affecting perceived ease of use, perceived usefulness and learning motivation. Furthermore, learning motivation is also a predictor to affect perceived usefulness. After that, perceived ease of use, perceived usefulness, and learning motivation are three important factors affecting learner intention to use the virtual reality learning environment.</p>

Real Time Application

In virtual reality technology, it is necessary to develop improvements and apply new techniques that allow rapid progress and innovative development. Nowadays, virtual reality devices have not yet demonstrated the great potential they could develop in the future. One main reason for this is the lack of precision to represent three-dimensional scenarios with a similar solvency to what our visual system obtains from the real world. One of the main problems is the representation of images using the RGB color system. This digital colorimetry system has many limitations when it comes to representing faithful images. In this work we propose to develop a virtual reality environment incorporating hyperspectral textures into a virtual reality system. Based on these hyperspectral textures, the aim of our scientific contribution is to improve the fidelity of the chromatic representation, especially when the lighting conditions of the scenes and its precision are relevant. Therefore, we will present the steps followed to render three-dimensional objects with hyperspectral textures within a virtual reality scenario. Additionally, we will check the results obtained by applying such hyperspectral textures by calculating the chromaticity coordinates of known samples.

The logging industry belongs to one of the industrial processing branches with the greatest risk of accidents at work. Unfortunately, such situations often result in serious injuries and even the deaths of employees. In most cases, the casualties are people who are badly trained and inexperienced, with a short employment history. One solution to avoid these tragedies is to support workers employed in this industry with training applications. This paper presents a description of a research and training platform for operating portable chainsaws using virtual reality (VR) technology. The platform simulates phenomena occurring while working with a chainsaw, such as falling tree parts, the occurrence of chips and characteristic sound effects. The study used the HTC Vive Pro set and a dummy chainsaw with an electric module, thanks to which the application lets you control a virtual chainsaw using a real life device tracked by a system for mapping objects in space. For the purpose of this work, a series of 32 tests were conducted with 16 subjects and conclusions were drawn on the basis of test reports and surveys, in which the subjects expressed their opinions about the course of events in the platform application.

With the continuous development and progress of virtual reality technology in recent years, the application of virtual reality technology in all aspects of real life is no longer limited to the military field, medical, or film production fields, but it gradually appears in front of the public, into the lives of ordinary people. The human-computer interaction method in virtual reality and the presentation effect of the virtual scene are the two most important aspects of the virtual reality experience. How to provide a good human-computer interaction method for virtual reality applications and how to improve the final presentation effect of the virtual reality scene is also becoming an important research direction. This paper takes the virtual fitness club experience system as the application background, analyzes the function and performance requirements of the virtual reality experience system in the virtual reality environment, and proposes the use of Kinect as a video acquisition device to extract the user’s somatosensory operation actions through in-depth information to achieve somatosensory control. This article adopts a real human-computer interaction solution, uses Unity 3D game engine to build a virtual reality scene, defines shaders to improve the rendering effect of the scene, and uses Oculus Rift DK2 to complete an immersive 3D scene demonstration. This process greatly reduces resource consumption; it not only enables users to experience unprecedented immersion as users but also helps people create unprecedented scenes and experiences through virtual imagination. The virtual fitness club experience system probably reduces resource consumption by nearly 70%.
