What this test checks
Visualise a controller stick's full reported range and estimate circularity, edge coverage and directional consistency.
InputAnalyzer processes test events locally and does not upload your raw inputs or result values.
How to run the test
Start from the centre
Release the selected stick, start the capture and wait until the centre is registered.
Trace the outer edge
Push the stick fully outward and rotate it slowly through several complete circles.
Cover every direction
Pay particular attention to corners or sectors that remain empty, then finish the capture.
How to read the result
Observed signals, not artificial certainty.
Balanced coverage
The trace reaches a similar radius around the full rotation without obvious missing sectors.
Uneven reach
Flat areas, spikes or a sector that consistently falls short may indicate calibration, wear or mapping differences.
What this test cannot prove
What the browser cannot see
- Circularity describes the normalised axes reported to the browser, not the physical gate or sensor geometry.
- Moving too quickly or failing to hold the outer edge can create apparent gaps that are not hardware faults.
- Results are browser-based estimates, not a physical hardware diagnosis.

Frequently asked questions
Short answers before you test again
Should the trace form a perfect circle?
No. Some controllers report a square-like or clipped range by design. Consistent coverage matters more than a perfect shape.
What does a missing sector mean?
It can mean reduced reach, but it can also come from an incomplete rotation. Repeat slowly before drawing a conclusion.
