ABSTRACT
The chat box allows missile controllers to receive messages that contain basic information about missile status as well as instructions for action or queries for information from superiors. In human-in-the-loop experiments conducted with TTIMR, questions appeared to come from a higher authority and queried the subjects acting as controllers about past, present, and future elements of missile and target status. This type of secondary tasking which requires spatial reasoning is called a problem-solving secondary task (Gawron, 2000).
