A method and apparatus for detecting the alertness of an equipment operator by displaying a moving icon, and asking the operator to track the movements of the icon, either by following it with the eyes in a head mounted display, or by following it with a finger on a touch screen. The operator's performance can be measured by tracking the gaze of the operator's eyes, or by tracking the operator's finger movements. The performance of the operator can be compared to that particular person's history of test results, or to a data base of test results of other operators. The characteristics of the icon can be varied, and distractions can be provided on the display or screen. Control of the display or screen, tracking of the operator's eyes or finger, and analysis of the test results, can all be performed by a computer.
