Follow the gaze
Scanpaths
Compare participants side by side on a shared time axis. Follow AOI order, dwell and playback in parallel scanpaths.
Iriscope · Eye-tracking analysis
Analyze gaze.
Explain the result.
Explore scanpaths, compare similarities, search AOI sequences and discover strategy clusters. Import recordings, calculate metrics and keep each result connected to its data and method.

Scanpaths · Similarity · Search · Clusters
Scanpaths, sequences & strategy clusters.
Follow individual paths, compare them, find a specific sequence or discover shared gaze patterns. These are separate tools in the same project.
Compare paths
Scanpath similarity
Compare participants or items with similarity matrices. Inspect AOI order, timing and spatial path differences using the selected method.
Find a pattern
Sequence search
Search sequences such as AOI 1 → AOI 3 → AOI 5. Highlight matches, allow intermediate AOIs or show only matching paths.
Discover shared patterns
Automatic strategy clusters
Group similar scanpaths automatically. Review representative paths, members, cluster quality and the recommended number of clusters.
Core features
What you can do with Iriscope.
See the main tools here. Open a feature for its workflow, settings and method details.
01 / Iriscope
Visual analytics & playback
Explore heatmaps, scanpaths, AOIs and gaze overlays on your stimuli. Use the timeline to follow the recording in context.
02 / Iriscope
Metrics & AOI statistics
Calculate fixations, dwell time, visits, reading measures and more. Inspect results across participants, stimuli and meaningful regions.
03 / Iriscope
Recording & project import
Import Tobii HDF5, EyeLink ASC and mapped CSV/TSV tables. Bring PeriTag AOIs and their stimulus context into the same project.
04 / Iriscope
Data quality & correction
Review validity, tracking loss and events. Preview reversible spatial corrections before applying them and recalculating affected results.
05 / Iriscope
Robustness Lab
Compare stored fixation methods on the same recording. See event agreement and how detection choices change counts, durations and AOI results.
06 / Iriscope
Metric Inspector & provenance
Inspect a metric’s definition, availability and calculation path. Keep the data, method settings and analysis history attached to the result.

More tools for your research question.
Reading: words & lines
Inspect first-pass reading, regressions, rereading and word/line AOIs, with the recorded reading layout in view.
Pupil, blinks & eye openness
Examine pupil responses, blink measures and eye openness using the channels recorded in your study.
Signals & eye-movement events
Inspect signal timelines and event measures, including saccades, microsaccades, smooth pursuit and binocular analyses where the data support them.
Transitions & entropy
See how gaze moves between regions through transition matrices, networks and AOI-sequence measures.
Recurrence & cross-recurrence
Inspect repeated patterns in one sequence or shared temporal structure between two, including recurrence views and lag profiles.
Condition & value search
Combine metric thresholds, signals and AOI sequences with AND, OR and NOT. Review hits and save timed matches as analysis windows.
Named analysis windows
Compare study phases with absolute, relative or participant-specific ranges and calculate their results separately.
Peripheral viewing geometry
Inspect foveal, parafoveal and peripheral zones and time-matched AOI intersections using the stored display geometry.
Result exports & method reports
Prepare global, AOI and pairwise result tables. Export selected metrics together with the method and provenance context.
