Trustworthy Interaction with Robot Swarms
Successful Interaction with autonomy depends crucially on human trust and its influence on reliance. In our work we are developing both normative models of performance based on proper calibration of trust and adaptive models by which autonomous systems can use indices of human trust to adapt their characteristics to improve performance of the overall system. While this would be challenging for a single robot we are working with very large (1,000+) swarms in CUDA-based simulations and a small swarm of 10 Turtlebots in the lab.
Formal Models of Human Control of Cyber Physical Systems
While formal models of human cognition have advanced greatly, formal verification of human-machine systems has remained limited to "engineering models" of human performance such as characterizing a human operator as an optimal controller. In this project we are seeking to develop a methodology for deriving models of human performance that capture the architectural idiosyncrasies of human cognition in an analytic form that can be used for formal verification. Work with a swarm control task is complete and current efforts are investigating the highly nonlinear problem of fluid maintenance in anesthesia.
The influence of Cultural Factors on Trust in Automation
This project seeks to develop a validated measure of trust in automation and investigate cultural differences in the concept and resulting behavior in samples from the US, Taiwan, and Turkey.
Cognitive Compliant Command for Multirobot Teams
In this project we are developing methods for commanding robot teams of various sizes and levels of autonomy. We have conducted studies examining the feasibility of scheduling operator attention to enable supervision of multiple robots. In other work we have investigated approaches allowing human supervision of robot swarms.
Modeling Synergies in Large Human-Machine Networked Systems
This research is mathematically and empirically based drawing on human data and models to characterize their behavior within the system. Research involved human control of multiple robots, cognitive modeling of human operators, and experiments and models of multi-human/multi-robot teams.
Cultural Models, Collaborations and Negotiation
Researchers from the University of Pittsburgh will lead in designing, conducting, and analyzing data from online negotiation experiments. Observing interactive negotiation is necessary to capture the processes to analyze and understand the dynamics of cooperation and negotiation and tipping points that could lead to beneficial or disastrous effects.
