Abstract: The Advanced Video Activity Analytics (AVAA) system is a full-motion video exploitation capability designed to reduce imagery analyst workload and enable faster and more-accurate production of intelligence products. Phase II of the human factors evaluation examined the impact an automated person–vehicle–object (PVO) computer vision algorithm pipeline had on imagery analysts' cognitive workload and performance during realistic scenario-based operations. The results from multiple measures indicate that AVAA's PVO pipeline did not significantly affect the measures analyzed for performance, cognitive workload, or situation awareness as compared with the baseline AVAA system. However, analysts identified multiple usability recommendations for AVAA that would improve usability and follow-on development.
