Real time modeling of the cognitive load of an Urban Search And Rescue robot operator

Urban Search And Rescue (USAR) robots are used to find and save victims in the wake of disasters such as earthquakes or terrorist attacks. The operators of these robots are affected by high cognitive load; this hinders effective robot usage. This paper presents a cognitive task load model for real-time monitoring and, subsequently, balancing of...

Estimating an operator’s cognitive state in real time: A user modeling approach

This paper presents a Cognitive Task Load (CTL) model designed to keep track of an operator’s mental workload, both quantitatively (amount of workload) and qualitatively (cognitive state). By integrating this model in a (semi-)autonomous robot, robot’s level of automation and user interface can be attuned to the operator’s state (Every second,...
