“…The software and application program interfaces (APIs), which facilitate graphics processing, and rendering and spatial algorithms are also computed relatively quickly, some even in realtime. Real spatial data, pre-made 3D objects, and graphics pipeline workflows [32] can be employed to create plausible virtual spatial compositions that can be supplemented with spatial data visualizations and evaluations [33,34].…”

Not all eye-tracking methodology and data processing are equal. While the use of eye-tracking is intricate because of its grounding in visual physiology, traditional 2D eye-tracking methods are supported by software, tools, and reference studies. This is not so true for eye-tracking methods applied in virtual reality (imaginary 3D environments). Previous research regarded the domain of eye-tracking in 3D virtual reality as an untamed realm with unaddressed issues. The present paper explores these issues, discusses possible solutions at a theoretical level, and offers example implementations. The paper also proposes a workflow and software architecture that encompasses an entire experimental scenario, including virtual scene preparation and operationalization of visual stimuli, experimental data collection and considerations for ambiguous visual stimuli, post-hoc data correction, data aggregation, and visualization. The paper is accompanied by examples of eye-tracking data collection and evaluation based on ongoing research of indoor evacuation behavior.

“…In traditional mathematical models, only the relationship between variables and the internal structure characteristics of variables are usually studied to describe the degree of influence of random events, which ignores its internal laws and state change trends. However, modern visualization can help researchers to understand and analyze the problems, causes, and development prospects in complex systems more deeply, so visualization technology is more and more widely used in mathematical research [10,11].…”

At present, with the development of society and economy, some new problems have emerged continuously. Among them, the more serious problem is that enterprises pay too much attention to economic benefits, which leads to problems in the development of many enterprises. Therefore, the problem caused by too much emphasis on economic benefits is one of the major economic problems. After this problem, our country’s economy began to focus on economic input and output in the subsequent development process. And, related personnel have also studied the economic input-output technology and model, which is an economic quantitative analysis method that has been widely used in various aspects of the economic field since its emergence. This paper firstly elaborates the theoretical knowledge involved, such as economic data, economic variables, and visualization techniques. Secondly it analyzes the application of scientific visualization techniques in the processing of economic variable data, which includes the techniques of preprocessing, mapping, drawing, and displaying the data. Finally, this paper investigates the application of mathematical models in economic variables input and output and the application of mathematical models in economic research, which can help us to better understand and use the knowledge of economics, thus providing strong support for solving practical problems. Also, this helps people to understand and grasp more about the macroarea, microaspect, and even the country as a whole.

“…Evacuation procedures of passengers onboard can be improved analysing the results of virtual experiments where humans are exposed, for instance, to fire and smoke and their level of stress is monitored (Cosma, Ronchi and Nilsson, 2016;Zhao et al, 2020). Also, VR/AR environment can be complemented with spreading of fire and smoke based on the results reached using computational fluid dynamics (CFD) procedures (Yan et al, 2020). Further, factors such as position and availability of emergency lighting, distance to exists or even sound alarm can be altered to develop better evacuation procedures (Lovreglio, Fonzone and dell'Olio, 2016).…”

Safety of passengers on ships is usually investigated based on data available from post-accident reports, experimental research and/or numerical modelling of emergencies. As for the numerical modelling, ship passenger evacuation falls within a greater set of pedestrian evacuation research in which extended reality (XR) technology is playing important role lately. However, XR still strives to find its place in the modelling of ship passenger evacuation. This paper brings review of literature published on the topic of XR in pedestrian evacuation with special focus on the use of these technologies (e.g. virtual reality, augmented reality) in shipping industry. Findings are put in the context of IMO’s guidelines for evacuation analysis and prospect for use of XR for ship passenger evacuation simulation are presented.
