Enabling Collaboration and Visualization of Complex Operational Technology Computer Networks With Augmented Reality Technology

Operational Technology OT networks are critical to mission operations on many naval platforms, yet it is often difficult to effectively communicate their status and engage in efficient decision-making at all levels of operation. While the complexity of networks has increased, visualization methods suiting the needs of a diverse set of users have not kept up. To address this problem, this research evaluated whether visualization, provided to a small group of operators acting in a shared work environment on network management, can be supported using commercial off-the-shelf, lightweight, portable augmented reality AR technology. The work included building a prototype AR OT network on a U.S. Navy guided missile destroyer DDG three-dimensional model with four decks and simulated interconnected ship systems. We then designed and implemented a network infrastructure between a set of Hololenses, and built an application that allowed multiple users to collaborate by viewing the same virtual model in a real-world space setting. A study tested the system interfaces usability and its value in network management scenarios. The results suggest that a lightweight AR system, with an interface that supports small-team collaboration, could be a valuable tool for increasing situational awareness in cyberspace and allowing effective team decision-making.
