SIGMA Builder
Design and test screens in the Live Editor, switch display formats, generate text AOIs and build gaze-contingent tasks. Exchange image and video regions with PeriTag.
SIGMA · Software for visual & behavioral research
Design the task.
Follow attention.
Explain the result.
Build experiments, prepare image and video AOIs, analyze gaze with documented methods, and share a project others can inspect. Four focused applications. One connected research workflow.

The research chain
Four roles. Connected by the study.
Choose the application for the work in front of you. Move between them with the material and analytical context still attached.
02 / ANNOTATE
PeriTag
Turn images and videos into named, editable regions. Combine manual annotation, OCR, model assistance, tracking and observation.
03 / ANALYZE
Iriscope
Compare analysis choices, inspect calculation lineage and connect metrics to visual evidence, temporal scope and project provenance.
04 / REVIEW
Iriscope Reader
Give collaborators access to prepared project views and stored results. Permanently free; the analysis stays protected from editing.
What stays connected
A result needs more than a number.
The visual material, AOI definitions, selected methods and analytical history remain part of the research workflow.
01
Material and regions
Send image and video stimuli from Builder to PeriTag. Return the annotated regions to the study and retain their relationship to the original components.
02
Method and calculation
In Iriscope, examine how event detection, AOI mapping and analytical scope contribute to a result. Compare stored alternatives in Robustness Lab.
03
Result and review
Share the prepared Iriscope project with the free Reader. Recipients inspect its stored views and reports without modifying the analysis.
Research applications
Built around the question you want to ask.
Combine the products for controlled laboratory tasks, existing recordings or time-aware video research.
Reading and visual access
Prepare native text and word/line AOIs in Builder. Use gaze-dependent visibility and inspect reading-related outputs in Iriscope.
Images, interfaces and objects
Annotate the regions that matter, map gaze to them and inspect paths, transitions and AOI metrics in visual context.
Video and desktop behavior
Prepare dynamic video AOIs in PeriTag or record a desktop-task phase in Builder. Preserve time context for later review.
Try the review workflow
Shared projects should stay inspectable.
The free Iriscope Reader opens prepared projects and their stored analytical state. No paid seat is required for the recipient.
