01
Stored methods only
Compare fixation sources that were actually calculated and stored in the project.
03 / Analyze · Robustness Lab
Challenge the fixation method.
Iriscope compares stored fixation methods and makes their impact on eye-movement events and downstream metrics visible — as a methodological robustness check, not an inferential result.
The capability
What you can inspect and control.
Use this workflow for the part of the research question it addresses.
02
Event agreement
Inspect optimal event matching, temporal overlap, count and duration similarity.
03
Result stability
See whether counts, durations, AOI dwell and a selected metric stay stable.
04
Provenance-aware
Exclude cases with mismatched input signatures rather than hiding the difference.
In the application
A workflow you can follow.
Keep the relevant material, definitions and review decisions connected at each step.
- Select one or more stimuli, participants and already stored fixation methods.
- Choose the event-agreement perspective: optimal F1 matching, temporal Jaccard, count or duration similarity.
- Inspect downstream stability for fixation count, mean and total duration, AOI dwell and an optional metric handed over from Metric Inspector.
- Review comparable cases, exclusions and the saved robustness report before interpreting the result.
Method context
Keep the scope of the result visible.
The relevant settings, prerequisites and interpretation stay attached to the workflow.
Method settings, scope and interpretation
A robustness score is a guide, not a statistical verdict.
The combined score is explicitly descriptive. It combines event agreement with stability across selected outcomes so researchers can investigate method sensitivity; it does not replace an inferential analysis or turn algorithms into ground truth.
