Julian Hough "Fluid uncertainty grounding for simple robots with speech understanding"

For effective Human-Robot Interaction (HRI), robots must go beyond having good legibility of their intentions shown by their actions, but also communicate the degree of uncertainty they have about what the human wishes the robot to do. I will show how in simple robots which have spoken language understanding capacities, uncertainty can be made common by principles of communicative grounding in dialogue interaction without the need for natural language generation responses. I will present a model which makes this possible for simple robots with limited communication channels beyond the execution of task actions themselves. The model is implemented in a simple pick-and-place robot, and an experiment was carried out with two simple strategies for grounding uncertainty. In an observer study, participants observing interaction with the robot run by the two different strategies were able to infer the degree of understanding the robot had internally, and in the more uncertainty-expressive system, the internal uncertainty the robot had. In the final part of the talk, I will show more recent work on developing a Types-As-Classifiers approach to perception and action in an HRI system.
