Key Findings
- 01Standard eye-tracking analysis (gaze plots, heatmaps, AOI statistics) is problematic for interpreting user behavior within dynamic 3D environments.
- 02Data related to menu bars is generally interpretable, but data from the 3D viewport itself is difficult or impossible to interpret.
- 03A methodological adaptation, instructing participants to avoid 3D manipulation during certain tasks, results in interpretable visualization techniques for eye-tracking data.
- 04The adapted methodology is considered useful and applicable for usability testing of 3D software.
Application
Design takeaway
When conducting eye-tracking studies for 3D software, consider implementing task constraints that limit 3D manipulation to improve data interpretability.
How to apply
When planning a usability study involving 3D software and eye-tracking, design specific subtasks where users are instructed to focus on specific elements without altering the 3D view. Analyze eye-tracking data separately for these controlled subtasks versus free-manipulation subtasks.
Project actions
- 01When designing tasks for your 3D software project, think about how user actions might affect data collection.
- 02Consider if you need to control certain user interactions to get the data you want.

Variables
Strengths & Limitations
Strengths
- +Addresses a specific, practical problem in usability testing of 3D software.
- +Proposes and tests a concrete methodological adaptation.
- +Uses multiple software applications for broader applicability.
Limitations
The specific software tested might not represent all 3D applications. The effectiveness of the 'no manipulation' instruction could depend on the user's skill level and the task's nature.
Reliability & validity
The study's validity is strengthened by testing across multiple software types. Reliability of the adapted methodology would depend on consistent application of instructions and participant adherence.
Think critically
To what extent does the proposed methodological adaptation of restricting 3D manipulation generalize to all types of 3D software and user tasks? Are there alternative methods to improve eye-tracking data interpretability in dynamic 3D environments without imposing such restrictions?
Design Principles
"For complex interactive environments, user task design can significantly influence the quality and interpretability of observational data."
Understanding user interaction with complex 3D environments is crucial for designing intuitive interfaces in fields like CAD, digital human modeling, and architectural visualization. When standard eye-tracking analysis methods fail to accurately capture user attention and cognitive processes during 3D manipulation, it hinders the identification of usability issues and the optimization of user experience.
What This Means for Your Design
When you use eye-tracking to see where people look in 3D software, it's hard to tell what they're looking at if they're always spinning and zooming the model. But if you ask them to keep the model still for certain parts of the task, the eye-tracking data becomes much clearer.

Paragraph starter
When evaluating user interaction with 3D software, standard eye-tracking methodologies can face significant challenges due to the dynamic nature of 3D manipulation. Research by Babicsné-Horváth and Hercegfi (2022) highlights that actions like rotating and zooming compromise the interpretability of gaze data. They found that while menu interactions are generally clear, data from the 3D viewport is problematic. Their work suggests that a methodological adaptation, specifically instructing participants to avoid manipulating the 3D space during certain tasks, can yield more interpretable eye-tracking visualizations, proving useful for identifying usability issues.
