Abstract:In ARL-TR-9623, we presented several multimodal measures for assessing team trust that were incorporated into a software tool called the Human-Autonomy Teaming Trust Toolkit (HAT3). The initial software document and user guide described the purpose, scope, assessment modules, and design of the HAT3 and provided instructional details and screenshots regarding how to use the two existing modules: subjective and communication. Since the initial report, several new capabilities for assessing team trust, cohesion, and workload have been added. The purpose of this addendum is to describe these new capabilities.
