Multiple Identity Tracking and Motion Extrapolation

Multiple Identity Tracking (MIT) is a research paradigm in which individuals track the location and individual identity information of several moving objects in the environment. The present study is an examination of how individuals are able to extrapolate the future movement of moving objects while they are masked. There has been conflicting research on the source of a decline in tracking ability; either the amount of time an object is occluded for, or the distance an object moved during an occlusion. Additionally, previous research has not included the use of a secondary visual search task in a mask. Our design was modeled after a task of a pilot, who has to divide his or her attention between flight information on a head-up display (HUD) and traffic information on a horizontal situation display (HSD), while maintaining good situation awareness on both sources of information
