Research on the Effects of Distraction-Based Feedback

In the face of a large amount of information in the command system, the commander of emergency relief needs to make efficient decisions. They get distracted when multitasking in parallel or when there is external interference. Typical task scenarios with visual distraction tasks and cognitive distraction tasks are selected to explore whether these two distraction will affect the commander’s performance. Ten participants were recruited to complete the experiment. ANOVA was used to determine the difference between undistracted, distracted, and distracted with feedback, followed by LSD. Experimental results show that visual distraction and cognitive distraction did affect the subjects’ performance, resulting in an increase in the completion time of the primary task and a decrease in the accuracy rate. The feedback for distraction was helpful in improving the performance. Based on the conclusion of this experiment, we suggest that the feedback of popups and dynamic icons could be used to remind users when designing interface and system development based on visual distraction. When based on cognitive distraction, the feedback of dynamic icons and sound effects could be used to remind users.
