The purpose of this document is to report on the Human Factors analysis of the MASC system supported
by Sandia National Laboratories grant number AN-2317. This document provides brief reviews of the MASC
interface, the mediation hierarchy and our multiagent test-bed. We will then provide a detailed description of
the analysis development, experiments and experimental analysis. Finally, a discussion will be provided which
describes the implication of these results for the various components of our system.
1 Introduction
The Multiple Agent Supervisory Control (MASC) system has been built to combine autonomoussystem aspects with
the human'sabilityto control asystem (teleoperation) via a human-machineinterface. We havede ned the mediation
hierarchy which expands upon Sheridan's ( 11]) de nition of supervisory control. The purpose of this hierarchy is
to permit the human operator to interact with the various system levels in order to allow the system to complete
feasible tasks. This hierarchy is the underlying concept of the MASC interface development. The combination of
the autonomous and telerobotic systems should create a more comprehensive semi-autonomous system which will
successfully complete the execution of task assignments. We de ned a hierarchy of supervisory intervention into the
