Does the tool upload my data?

No. The calculations and CSV summaries run in the browser. Exported summaries are generated locally from the values you enter.

How does this relate to ConductVision?

The free tool helps document or prepare a research workflow. ConductVision Human Tracking performs markerless analysis on research video and exports keypoints, overlays, and metrics.

Research use only. This tool is for education, protocol documentation, and research workflow planning. It is not for care decisions, participant triage, or health advice.

When to use

For research protocol documentation and descriptive session summaries
For preparing ConductVision Human Tracking video workflows
For organizing export-ready methods text, filenames, or CSV quality checks

Do not use for

For care decisions, participant triage, or health advice
As a substitute for IRB-approved protocol definitions or trained research review
As proof that a study endpoint has been validated in your study population

Keep the language research-only

Use participant, subject, trial, protocol, and research session language. Avoid care-directed interpretations.

Preserve raw files and exports

Store source video, keypoint exports, confidence values, and session notes so outputs remain auditable.

Pilot before full capture

Run one short pilot and inspect visibility, lighting, scale references, and keypoint confidence before collecting a full dataset.

Method

The tool performs deterministic arithmetic, checklist generation, or CSV summary operations in the browser. It does not assess injuries, classify participants for care, or replace a protocol approved for research use.

Validated

Last validated 2026-06-02. Calculations are designed for planning and documentation support; verify procurement decisions against manufacturer specifications or institutional SOPs.
