Research on Eye Movement Parameters of Command and Control System Operator Based on Emma Model

Abstract

Eye movements and movements of attention (EMMA) model divides eye movement behavior into two parts: eye movement preparation and eye movement execution. The time of eye movement preparation tends to be fixed for special groups, while the time of eye movement execution depends on the saccade speed and saccade distance of human eyes, and the saccade speed tends to be fixed for special groups. EMMA’s previous research did not involve operators of command and control system, so this paper carried out experiments on the acquisition and analysis of eye-movement preparation and eye-movement execution data for 20 people. The results of the experiment showed that the average eye movement preparation time of the command and control system operators was 136.15 ms and the average saccade speed was 1.3 ms/deg. The above research not only improves EMMA model in the field of command and control system, but also lays a foundation for later cognitive behavior modeling of operators.
