Usability Evaluation and Improvement of Mission Planner UAV Ground Control System's Interface

摘要

This paper aims to improve the usability of Mission Planner UAV ground control system's interface through interface improvement. The questionnaire survey and user interview were utilized to evaluate the usability of the UAV ground control system's interface, and the C programming language was used to improve the usability problems. Then, the eye-tracking experiment was designed to compare the difference in usability between the improved system interface and the original system interface, which was used to verify that the improvement to the system interface was effective. The result showed that the usability problems mainly existed in flexibility, minimal user action, minimal memory burden, and user guidance dimension, and the analysis result of multiple indexes such as task completion time, mouse click and fixation points indicate that the usability of the improved system interface was better than the original system.
