Updating Parameters of Fitts' Law Based on Multi Monitor Command and Control System

At present, the previous studies on the parameters of Fitts' law in the command and control system interface are mostly carried out in a single monitor system. However, with the increase of the complexity of the command system, the amount of information that needs to be displayed becomes more and more large, so the system needs to display information with the help of multi monitor, and cross-screen operation is also needed for the operation of the system. In the multi-monitor command and control system, aiming at the mouse click behavior, this study uses Fitts' law to model. Through the analysis of the collected data, the functional relationship between the movement time, the motion amplitude and the width of the target area is updated under the multi monitor command and control system, and the time of predicting the human-computer interaction of the multi monitor command and control system is quantified. The new fitting function can provide strong support for man-machine interface design and human factor engineering research of multi-monitor command and control system.
