Controller Evidence Lab
Inspect raw controller axes and buttons in your browser, run a hands-off or range protocol, and export comparable JSON/CSV evidence without claiming hardware latency.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
Editorial responsibility
KitForma maintains this tool and its guides. The source notes on the tool page link to the supporting documentation. We do not claim affiliation with the referenced hardware manufacturers or platforms. Review date: 2026-10-19.
Limits and updates
