Using VR to Validate and Visualize MBSE-Designed Interfaces

Several unique challenges arise in the new field of integration between Model-Based Systems Engineering (MBSE) models and game-based digital twin visualizations. First, no known standardized interfaces between the MBSE model and game engine visualization are defined, which can lead to custom or stove-piped solutions. Additionally, visualizing digital twin models in true to life scale is insufficient with typical desktop computers. The Bi-Directional Interface Requirements Operational System Test (BIFROST) prototype, funded by the US Army Program Executive Office (PEO) Aviation, seeks to address these challenges.

Progress of the BIFROST prototype is covered in the paper. The prototype aims to determine the feasibility and challenges of validating interfaces through visualizing changes to an MBSE model in a 3D game engine. Research was performed to visualize part of an uncrewed aircraft system ground control station in 3D using the Unity game engine. A Mission Control Architecture MBSE model, developed by PEO Aviation, is used to drive the digital twin of the ground control station through a set of virtual reality (VR) controls. Users can visualize, analyze, and test the human-machine interaction of the 3D models in VR prior to real-world system changes. This paper presents the recommended interfaces between the MBSE model and 3D engine, lessons learned, and future research areas.
