Modeling and Making Use of Human->Robot Trust
Anqi Xu , PhD student, SOCS McGill

Area: Robotics

Abstract:

We are interested in identifying computational models of “trust” in human-robot systems that are inferred from their interactions, and inspired by similar concepts relating to trust among humans. This computable quantity will allow a robot to estimate the extent to which its performance is consistent with a human’s expectations, with respect to task demands. We present an initial model of trust based on utility theory, and demonstrate how it can be coupled with an adaptive mechanism that dynamically adjusts the robot’s autonomous behaviors, in order to improve the efficiency of the collaborative team. This trust-driven methodology is instantiated using an interactive visual robot navigation system, and is evaluated through controlled user experiments as well as a field demonstration using an aerial robot.
