Hardware Boundary Notice: This test displays motion telemetry reported by your browser via DeviceMotionEvent. It does not independently calibrate sensor bias or verify laboratory-grade physical measurement accuracy. Values reflect operating system sensor-fusion calculations.
How to test
START MOTION SENSOR: Click 'Start Sensor' to begin reading motion events. On iOS devices, tap 'Allow' when the browser requests permission to access motion sensors.
2D G-FORCE RETICLE: Tilt your phone or tablet in any direction. The visual reticle puck will displace according to gravitational pull along the X and Y axes.
3-AXIS TELEMETRY: Inspect linear acceleration (excluding gravity) and total acceleration (including gravity) across X, Y, and Z axes to verify sensor responsiveness.
