Treat a completed multi-sample window as evidence of the browser-delivered controller signal.
IP-CTL-01 / AXES / BUTTONS / TIME
Controller Stick Circularity Test
Sweep the stick gate and inspect axis range, angular coverage and circularity reference.
Aim or movement feels uneven near the edge of the stick gate.
This focused entry uses the shared Controller protocol. The measurement logic and Evidence version remain identical to the complete lab.
Remove the easiest false alarms first.
01
Connect one controller, press a button and keep this tab visible.
02
Place the controller on a stable surface before any idle capture.
03
Test USB and Bluetooth as separate sessions instead of changing mid-run.
Run one repeatable protocol.
- 01
Start the guided stick sweep.
- 02
Trace the outer gate several times without cutting corners.
- 03
Compare X/Y range, radius and 36-bin angular coverage.
Evidence the result should expose.
DIRECT / INFERREDX/Y range
DIRECT / INFERREDMaximum radius
DIRECT / INFERREDAngular coverage
DIRECT / INFERREDCircularity reference
Separate observed, review and inconclusive.
Repeat the same protocol twice with the same connection before escalating persistent drift, bounce or missed transitions.
No Gamepad API signal, an unsupported actuator or one release spike cannot prove a physical controller fault.
Start with the likely path, then retest.
01
Restricted mechanical gate
02
Calibration scale
03
Incomplete user sweep
