Novel learning framework for optimal multi-object video trajectory tracking

BackgroundWith the rapid development of Web3D, virtual reality, and digital twins, virtual trajectories and decision data considerably rely on the analysis and understanding of real video data, particularly in emergency evacuation scenarios. Correctly and effectively evacuating crowds in virtual emergency scenarios are becoming increasingly urgent. One good solution is to extract pedestrian trajectories from videos of emergency situations using a multi-target tracking algorithm and use them to define evacuation procedures. MethodsTo implement this solution, a trajectory extraction and optimization framework based on multi-target tracking is developed in this study. First, a multi-target tracking algorithm is used to extract and preprocess the trajectory data of the crowd in a video. Then, the trajectory is optimized by combining the trajectory point extraction algorithm and Savitzky–Golay smoothing filtering method. Finally, related experiments are conducted, and the results show that the proposed approach can effectively and accurately extract the trajectories of multiple target objects in real time. ResultsIn addition, the proposed approach retains the real characteristics of the trajectories as much as possible while improving the trajectory smoothing index, which can provide data support for the analysis of pedestrian trajectory data and formulation of personnel evacuation schemes in emergency scenarios. ConclusionsFurther comparisons with methods used in related studies confirm the feasibility and superiority of the proposed framework.

Immersive virtual reality as a social research environment. The impact of the presence of an embodied agent on the Stroop task performance based on own research

This empirical study examined the effects of the presence of others (physical observers and embodied agents) on the performance of the Stroop task within an immersive virtual reality (VR) environment. Drawing from the research conducted by Pascal Huguet and his colleagues, who explored the social facilitation and inhibition effects in traditional lab conditions using the Stroop test, the current study sought to test these effects in VR conditions. Participants were divided into four groups, each experiencing different conditions – performing the task alone, under the awareness of being observed, or in the presence of embodied agents (formally dressed as Dr. Piotr or casually as Piotrek). A one-way analysis of variance (ANOVA) for independent samples was conducted to evaluate the results. Findings showed a significant reduction in Stroop interference when participants were aware of being observed by the experimenter. However, the presence of embodied agents in the VR environment, regardless of their regardless of their dress or manner of presentation, did not significantly influence the results. These results not only confirmed the occurrence of the Stroop interference effect in VR conditions, comparable to traditional lab conditions, but they also suggested that the social presence of the experimenter could enhance task performance in the VR environment. There was no significant influence observed from the presence of embodied agents, though. These observations can greatly contribute to the development of VR. However, further research is required to expand these findings, considering factors such as sample size and realism of embodied agents.

Cognitive Load Estimation in VR Flight Simulator.

This paper discusses the design and development of a low-cost virtual reality (VR) based flight simulator with cognitive load estimation feature using ocular and EEG signals. Focus is on exploring methods to evaluate pilot's interactions with aircraft by means of quantifying pilot's perceived cognitive load under different task scenarios. Realistic target tracking and context of the battlefield is designed in VR. Head mounted eye gaze tracker and EEG headset are used for acquiring pupil diameter, gaze fixation, gaze direction and EEG theta, alpha, and beta band power data in real time. We developed an AI agent model in VR and created scenarios of interactions with the piloted aircraft. To estimate the pilot's cognitive load, we used low-frequency pupil diameter variations, fixation rate, gaze distribution pattern, EEG signal-based task load index and EEG task engagement index. We compared the physiological measures of workload with the standard user's inceptor control-based workload metrics. Results of the piloted simulation study indicate that the metrics discussed in the paper have strong association with pilot's perceived task difficulty.

User-centric immersive virtual reality development framework for data visualization and decision-making in infrastructure remote inspections

Data visualization and decision-making are critical aspects of infrastructure inspections. Numerous research efforts have been made to develop practical remote inspection systems that overcome the limitations of conventional inspection methods. Although the integration of Immersive Virtual Reality (IVR) into remote inspection is currently being addressed, most IVR frameworks have focused on data accuracy and there has been a lack of research on developing human-centered IVR frameworks through usability evaluation. This paper addresses this limitation by proposing a new IVR development framework utilizing agile User Experience (UX) design techniques, which can be implemented in remote infrastructure inspections for data visualization and decision-making. Usability tests were conducted through a case study with 22 participants, using an IVR prototype developed in accordance with this framework. Following its implementation, the framework demonstrated its ability to identify damage via remote bridge inspection and achieved acceptable usability. Future research can build on the framework for semantic enrichment tasks.
