It entails interpreting vast amounts of data from sensor networks integrated into dam structures. The application of extended reality technologies for situated immersive analysis allows data to be contextualized directly over the physical referent. Such types of visual contextualization have been known to improve analytical reasoning and decision making. This study presents DamVR, a virtual reality tool for off-site, proxied situated structural sensor data visualization. In addition to describing the tool&rsquo;s features, it evaluates usability and usefulness with a group of 22 domain experts. It also compares its performance with an existing augmented reality tool for the on-site, immediate situated visualization of structural data. Participant responses to a survey reflect a positive assessment of the proxied situated approach&rsquo;s usability and usefulness. This approach shows a decrease in performance (task completion time and errors) for more complex tasks but no significant differences in user experience scores when compared to the immediate situated approach. The findings indicate that while results may depend strongly on factors such as the realism of the virtual environment, the immediate physical referent offered some advantages over the proxied one in the contextualization of data.}, DOI = {10.3390/computers13020035} }

Its primary objective is to ensure the safety and optimal performance of these structures. This undertaking involves the abstraction and interpretation of extensive structural, hydraulic, and geotechnical data, typically acquired through sensor networks embedded within the dam. This study introduces 'DamVR', a virtual reality tool for situated dam safety control data visualization. This tool allows dam engineers and other industry professionals to analyze the fluctuation of structural behavior over time. Its immersive environment contains a realistic representation of the dam structure, networks of sensors, and surroundings. It aims to frame the data within the visual context of the object of the analysis. This contextualization is intended to improve analytical reasoning and decision-making. The usability of DamVR was evaluated by a group of domain experts and compared to an existing augmented reality tool in similar tasks. The results indicate that DamVR is a usable and effective dam safety control data visualization tool.}, doi={10.1109/ICGI60907.2023.10452725}}
