Usability Evaluation of Hybrid 2D-3D Visualization Tools in Basic Air Traffic Control Operations.

Nowadays, increasing attention has been drawn to hybrid 2D-3D visualization tools, while evaluating them with a convenient and objective tool has only been carried out in a small number of areas. In this study, a revised radar chart-based usability evaluation approach was proposed. The approach was adopted to evaluate the hybrid 2D-3D radar display in air traffic management. The holding stack in air traffic management is analyzed and simulated, two generic tasks are designed accordingly. The hybrid 2D-3D radar display settings are evaluated based on six indicators from eye-tracking and brain dynamics data, namely, the frequency of fixation, fixation mean duration, fixation time on an area of interest, emotion, workload, and stress. The results reveal that the hybrid 2D-3D radar display induces spatial memory loss and high workload, while requires a shorter fixation duration.
