Different solutions present the usage of bicycles with Head Mounted Display (HMD) in which virtual scenarios are visualized as background for athletes trainings or as cardiac patient rehabilitation systems. However, assessments on presence, degrees of immersion and user involvement with real bicycles in those virtual scenarios still are rare. In this paper we present a haptic interface of a real bicycle using HMDs as a mixed reality display using a procedural city as a background scenario. To measure and evaluate presence, two experiments had been conducted. One that simulates a virtual reality mode and a second that corresponds to a mixed reality mode. By think aloud method, it was possible to analyze the degree of presence, through control, focus, immersion and involvement factors. Six of the seven participants described that immersion is augmented as well as the feeling of presence in the mixed reality interface, feeling a better experience with the improvement of movements. Issues related to comfort and the visual graphic were also evaluated with some results on the stimulus that also opens new possibilities for future works in different areas.
To mitigate risks and improve performance during the drilling of an oil well and its various hole sections, it is recommended that its operational parameters and trajectory be monitored in real-time. This activity is crucial to avoid several problems during drilling campaigns, especially if the drilling specialist can have all the data and some level of automatic interpretation on hand, so quick decisions can be made. However, most current monitoring software do not have an interactive or immersive visualization of this data, only track plots with multiple curves. To improve specialist experience, a 3D visualization system has been developed to unify both the drilling monitoring and analysis process of charts, drilling trajectory, lithology, and seismic data. The Divisor system consists of a cloud platform that unifies and processes data from different sources and a digital 3D visualization application. Its visualization module can be used in two forms: a traditional desktop interface enhanced with 3D visualizations and an immersive mode using a Virtual Reality (VR) headset. Both allow the operator to view real-time or historical data in multiple ways, perform assessments and simulations. Additionally, in VR mode, it is possible to navigate through a full-scale virtual environment, interact with the drill hole tridimensional visualization, and freely position charts with the essential variables to be monitored. This allows for better data manipulation granting better insights related to the numerous data captured, improving the decision-making process and enhancing the interaction in troubleshooting activities. The visualization application connects to a database that contains both static/design information and real time data, enabling a deeper analysis of all data together and the execution of artificial intelligence (AI) algorithms to generate new information and predictions according to the collected data. With both tools working in synchronization, it is possible to insert data from reports, convert them to a readable standard format, and generate visualizations customized by the user. The streamlining of consumption, analysis, and understanding of data allows for savings through the reduction in the numbers of software used as well as the time required for their implementation. The system can also be used as a training environment using historical data to operators in order to check their capacity of response in different scenarios, as well as guarantee the consistency of the operational activities. As future work, this tool will be extended with more views in VR and desktop modes, including new data generated by AI and comparison of design data (real and simulated), as well as an integration with a Digital Twin platform.
Over the last decade, most of studies were focused on assessments of presence, degrees of immersion and user involvement with virtual reality, few works, however, addressed the mixed reality environments. In virtual reality, mostly through an egocentric point of view, the user is usually represented by a virtual body. In this work, we present an approach where the user can see himself instead of a virtual character. Different than augmented reality approaches, we only detach the user's body and his/her proxies interfaces. We conducted four experiments to measure and evaluate quantitatively and qualitatively the feeling of presence. We measure and compare the degree of presence in different modes and techniques of representation of the user's body through virtually integrated questionnaires. We also analyzed what factors influence to a greater or lesser feeling of presence. For this study, we adapted a real bike with an haptic interface. Results show that there is not necessarily a better or worse type of avatar, but their appearance must match the scenarios and others elements in the virtual environment to greatly increase the participant sense of presence.
Well drilling is one of the most expensive tasks in oilfield exploration and development projects, especially in offshore assets. Thus, this activity is under constant evolution, given that any improvement in equipment or process can result in significant savings for the company operating that field. Meanwhile, virtual reality (VR) is one of the vital industry 4.0 trends to enable simulations and training safely for users. This work aims to provide a new tool to increase the drilling team’s efficiency by recreating drilling visualizations in a virtual environment. This environment enables training, evaluating, and simulating different scenarios in a well drilling and provide realtime insights to the engineers when coupled with other diagnostics tools.
Human exposure is a relevant factor when operating in critical environments and depends on a thorough analysis and consideration towards driving the teams to a safer and more productive environment. Reducing such exposure through digital technologies benefits the whole workforce in their decisions and maneuvers, like simulations, training, and other critical activities that can be executed remotely and prior to the actual activity. This paper presents a case study to demonstrate how augmented and virtual reality can be used to create a high fidelity virtual environment emulating the real industrial facility. This approach enriches the Digital Twin with the association of data and the virtual environment. It leverages on display and interaction capabilities of hardware devices, and intelligence and data querying capabilities of industrial software, empowering the workers with enhanced training capabilities and access to information increasing safety and efficiency. A real application of this technology is presented in this paper through the case study of the PredictMain4.0 project of Repsol Sinopec Brazil (RSB), which aimed at the integration of digital technologies, including augmented reality (AR) and virtual reality (VR). The PredictMain4.0 project was executed using data and data models of PETROBRAS’ P-50, a FPSO (Floating Production Storage and Offloading) operating in Brazil, and illustrates how different AR/VR applications can be developed and used in combination with engineering, operation, and maintenance databases. This includes 3D models, digitalized critical procedures, and the ability to integrate field teams into a single virtual environment, allowing real interaction in a digital setting that is linked to the real world. Considering the digitalized procedures, this paper aims to establish how virtual simulation and training can make teams more confident and prepared to execute the same physical asset procedures. After consulting with stakeholders from many different teams, the PredictMain4.0 project team selected three critical operating modules in the FPSO (Power Generation, Water Injection, and Gas Compression). For each one, considered which situations were relevant, should they occur. These situations led to developing a training and simulation framework, allowing instructors to create different scenarios and use advanced features such as digital measurement, real-time data collection, and collaborative sessions. The case study indicates that the development of such applications can save more than $1 million per year in maintenance costs considering the decrease in downtime and avoiding risks of accident.
