Intelligent Agent Transparency

Abstract

We evaluated the usability and utility of an unmanned vehicle management interface that was developed based on the Situation awareness–based Agent Transparency model. We sought to examine the effect of increasing levels of agent transparency on operator task performance and perceived usability of the agent. Usability and utility were assessed through flash testing, a focus group, and experimental testing. While usability appeared to decrease with the portrayal of uncertainty, operator performance and reliance on key parts of the interface increased. Implications and next steps are discussed.
