Automated systems, ranging from robots to intelligent planning aids, are increasingly part of the cognitive landscape. A pressing question facing the human factors community is how to design the automation to foster effective collaboration between the human and automated agents. This panel brings together leading researchers actively engaged in design of decision-support systems that involve some element of 'cognitive work' automation. They represent a variety of domains and a variety of approaches to design of collaborative automation. Panel members will discuss unique challenges of their respective domains, including differences in temporal rhythm, and how these have shaped their perspective on 'collaborative aiding'.
