Measurement of trust in human-robot collaboration

We describe a Collaborative Performance Model that captures the critical performance attributes of the distinctive human-robotic decision and control environment. The literature and our initial experimental studies show that the element of trust in human-robot collaboration is an extremely important factor in the Performance Model, and accordingly we have focused much of our attention on deriving suitable and practical measures of this variable. In this paper we describe the formulation of a decision-analytical based measure of trust as well as the results of two initial experiments designed to examine trust in a tactical human-robot collaborative task performed in our new Mixed Initiative Team Performance Assessment System (MITPAS) simulation environment.
