摘要

Supervisors in command and control settings are prone to frequent interruptions. While providing a visual timeline of events has shown promise in helping mission supervisors recover from interruption, it is not clear if providing such assistance on secondary displays compared to main displays would optimize the allocation of visual resources. A lab study was conducted with fourteen participants to compare the effects of providing interruption recovery support on the main mission displays, versus a secondary display, on participants’ recovery times after interruptions and decision accuracy. Integrating the tool into the main mission display significantly reduced interruption recovery time, but only during simple decisions. Meanwhile, integration into the main mission display adversely affected accuracy on complex decisions. While co-location of interruption recovery assistance with other mission information may help recovery, such proximity may result in information overload in complex decision-making contexts. Findings have implications for improving interface design and enhancing supervisor performance in similar time- and safety–critical environments.
