Rapid Interpretation of Temporal–Spatial Unmanned Aerial Vehicle (UAV) Operational Data – RITSUD: Aiding UAV Operators With Visualizations of Patterns-of-Life Activities

To accomplish their missions, the operators of military unmanned aerial vehicles (UAVs) aggregate and process information from multiple sources under time constraints, while experiencing partial sensory deprivation. We aimed to design, develop, and evaluate the need for designated information aids in the form of visualizations of spatial and temporal patterns-of-life for specific operational mission phases. In an evaluation conducted to assess the usefulness of the proposed visualizations, experienced UAV operators from two nations were presented with five scenarios in a narrative format. Each scenario contained one information-aid visualization for a specific mission phase. Participants had to interpret each mission phase and rate the information aid. Results showed that, in general, most operators favored the aids, but their appreciation of specific aids depended on the mission phase. There were also statistically significant differences between the nations. The results emphasize the potential for equipping UAV operators with information aids in the form of visualizations of spatial and temporal patterns-of-life. Moreover, the findings underline the need for more rigorous analyses of operators’ missions, as the need for specific visualizations was shown to vary with mission phase, and some visualizations were found to be more widely useful than others.
