6 May 2009 The placement of visual alerts in a shared display system
Author Affiliations +
In many command centers, operators are required to monitor multiple displays and perform several complex data tasks simultaneously. Multiple display systems may include two or more individual desktop monitors or the utilization of a large, shared, wall display configuration. Using multi- or shared display systems can be beneficial in alleviating individual desktop clutter as well as providing access to task-relevant information and facilitating situation awareness, but only if the operators know the information is available. Using visual alerts is one way to inform operators that updated or new information has been added to a shared display. The present study investigated the placement of visual alerts in a multi-display configuration. Ten participants performed spatial tasks on either a desktop monitor or a large wall display. Participants concurrently monitored both displays for a visual alert. The alert was presented on either the same display as the task (task/alert same) or the non-task display (task/alert different). The dependent measure was the response time to perceive the visual alert. Overall, participants responded faster when the visual alert was presented on the non-task display, but this effect depended on the location of the central task (desk, wall) and proximate location of the alert (top or bottom of the display). Limitations of the present study and future research considerations will be discussed.
