Look, Don’t Touch

With each new technology interface introduced in the environment, users spend more time switching between and managing these interfaces. When the interfaces involve screen-based displays and controls, eye movements may provide an intuitive and efficient means of switching between screens. This research focused on evaluating manual keyboard and gaze-based control methods for switching control between displays of a simulated surveillance system. Results showed that gaze-based tracking was faster and produced lower subjective workload than using a manual keyboard. Operators’ performance was also consistent with Keystroke-Level Model–Goals Operators Methods Selection predictions for each control method. These findings identify gaze-based control as a viable method for switching control between multiple monitors.
