Visual Alerting in Complex Command and Control Environments

A study was conducted to investigate automated visual alerting in complex environments where operators rely on multiple display workstations to perform high-intensity tasks. Two forms of alerts - a short red sidebar and a red border around the perimeter of the workstation display - were examined, as well as two forms of alert state - static and flashing. Results showed that the sidebar alert was detected faster than the border alert regardless of whether it was flashing or static, and in general, sidebar alerts were detected faster when they appeared on all three displays as compared to one display. Future work will focus on examining the association between the display an alert appears on and the spatial location of operator attention.
