Comparative analysis of touchscreen inceptors and traditional sidesticks on flight decks: flight performance, visual behaviours and situation awareness
通过21名飞行员在模拟仪表着陆系统中的实验，比较了触摸屏操纵器与传统侧杆在飞行性能、注意力分配和态势感知上的差异，发现触摸屏在姿态干扰场景下表现更差。
The concept of touchscreen primary control device is a novel approach of touchcreen implentation. The objective of this study is to investigate differences in flight performance and attention allocation between a touchscreen inceptor and a traditional sidestick. Twenty-one participants flew four simulated instrument landing system (ILS) approaches - with the touchscreen inceptor or traditional sidestick - during flight scenarios where an aircraft attitude disturbance was either present or absent. Results demonstrated that participant performance scores were worse with the touchscreen inceptor compared to the sidestick during attitude disturbance scenarios. Interestingly, participants exhibited reduced attention to external visual cues with the touchscreen inceptor compared to the sidestick. In addition, use of the touchscreen inceptor resulted in lower performance and lower self-reported situation awareness. Overall, the touchscreen inceptor demonstrated poorer performance compared to the traditional sidestick, highlighting limitations in its current design that warrant cautious consideration and further investigation.
