Key Findings
- 01Significant differences in saccade duration were observed across the searching, pursuing, and lock-on phases.
- 02Pupil size varied significantly, with the largest size recorded during the lock-on phase.
- 03Experienced pilots demonstrated better situational awareness, focused more on the Head-Up Display (HUD), and spent less time looking outside the cockpit compared to novice pilots.
- 04Pilots with better situational awareness exhibited smaller pupil sizes during the lock-on phase.
Application
Design takeaway
Design interfaces to support the changing attentional demands of users in dynamic tasks, and consider how experience influences attention allocation.
How to apply
When designing interfaces for high-stakes, dynamic tasks (e.g., air traffic control, surgical equipment), map user attention flow across different task phases and ensure critical information is readily accessible during high-demand moments.
Project actions
- 01When studying user interaction with a product, consider how their focus shifts over time.
- 02Think about how to make important information more visible when the user is under pressure or performing a complex task.

Variables
Strengths & Limitations
Strengths
- +Use of objective eye-tracking data.
- +Inclusion of both experienced and novice participants for comparison.
Limitations
Simulations may not fully capture the stress and complexity of real-world scenarios. The sample size, while reasonable, could be larger for broader generalizability.
Reliability & validity
The study's use of standardized eye-tracking equipment and a controlled simulator environment enhances reliability. Validity is supported by the correlation between experience, attention allocation, and performance metrics like situational awareness.
Think critically
How might the findings on pupil size and saccade duration be used to infer cognitive load in other design contexts beyond aviation?
Design Principles
"Dynamic task phases require adaptive interface design and user training to match attentional focus."
Understanding these shifts is crucial for designing more effective cockpit interfaces and training programs. By aligning display elements with pilot attention, designers can reduce cognitive load and improve operational safety and performance in complex, dynamic environments.
What This Means for Your Design
When pilots are trying to find, chase, and then lock onto an enemy plane, their eyes move differently and their pupils get bigger or smaller. Experienced pilots are better at knowing what's important to look at, like the information on their dashboard (HUD), instead of just looking out the window.
How to use in your project

Paragraph starter
This study by Yu et al. (2015) highlights that user visual attention is not static but dynamically shifts across different task phases. Their findings in a pilot simulation demonstrated significant changes in saccade duration and pupil dilation during target search, pursuit, and lock-on, indicating varying cognitive loads. Furthermore, experienced users allocated attention more effectively, prioritizing critical display information (HUD) over peripheral visual input. This underscores the importance of designing interfaces that adapt to or support these dynamic attentional shifts, ensuring critical information is presented optimally during high-demand moments to enhance user performance and reduce errors.
