Typical Analysis Workflow
The typical workflow for analyzing EyeLink data in Data Viewer involves the following steps:
- Import Data: Open Data Viewer and import your EDF files using File → Import Data → Multiple EyeLink Data Files. Save the new viewing session in an appropriate location, such as a "results" subfolder within your project directory.
- Set Interest Period: Define the temporal window for your analysis (e.g., from stimulus onset to participant response) by setting an Interest Period. This step is crucial for most reports.
- Review and Refine Data: Inspect the data using the Temporal Graph, Spatial Overlay, or Animation Playback views. In the Temporal Graph and Spatial Overlay views, you can adjust fixations and saccades or create Interest Area (IA) templates to apply to other trials.
- Group Trials and Explore: Use Trial Grouping (Edit → Trial Grouping) to organize trials by key variables. This is helpful for creating heatmaps or using the aggregate data mode to explore patterns in gaze behavior.
- Output Reports: Generate reports at the Trial, Interest Area, Fixation, Saccade, or Sample level. You can also create specialized reports, such as:
- Message Reports
- Time Series (binning) Reports for dynamic stimuli
- Aggregated Reports (if you have grouped trials)
- Message Reports
