Track. Measure. Verify.
Keep the headset awake and facing the controller play area. The screen stays in a stable local reference space when you move the headset. A reference-space reset requires a new calibration.

Checking WebXR support…
Passthrough is optional and available only if this browser supports immersive AR. With VR, follow the external screen after placing the awake headset underneath it.
Calibration method
Aim at four orange screen targets from position A. Move about 50 cm sideways, then repeat from position B. Hold still for each capture. A single viewpoint cannot determine screen distance.
Measured-reference offset
Only for corner measurement: metres from the controller grip-space origin to a known rigid reference tip. Do not press against the screen. A tracked origin is not automatically the plastic tip.
Waiting for pairing
Simulation for development
Pair with a separate screen tab, then simulate the two-position workflow without XR hardware.
