OCULOMETER MEASUREMENT OF AIR TRAFFIC CONTROLLER VISUAL ATTENTION

To evaluate the oculometer as a visual fixation measuring device for man/machine interface investigations, six air traffic controllers performed simulated radar control functions. A seventh controller performed the control tasks, while both an oculometer record and a manual record were made of visual attention. It was found that all the controllers spent approximately 80 percent of the test time looking at the radar display, with a mean of 76 glances at the display per 15-minute session. Average glance duration was 10 seconds. Approximately 11 percent of the remaining time was spent looking at the flight progress strips, less than 5 percent looking at the computer input keyboard, and less than 3 percent looking at miscellaneous or indeterminate objects. In the comparison of methods of recording visual performance, good agreement was obtained between the oculometer and manual kymograph recorder on time spent looking at the radar, flight strips, and keyboard. It was concluded that the oculometer has the potential to produce reliable and accurate information when used within the limits of its design.
