Sensitivity

Gain applied to pitch/roll tilt from the hand-tracking IMUs before it moves the cursor. Higher = faster cursor for the same tilt.

Deadzone

Tilt below this angle is zeroed out before it reaches the cursor, so a resting hand doesn't drift. Firmware spec calls for 2°–3°.

ML Confidence

Minimum match certainty the Edge Impulse model needs before a gesture fires a keystroke. Lower catches more gestures but risks false positives.

Haptics

Drives the DRV8833 straight off the 3.7–4.2 V LiPo, so the 8-bit PWM value maps directly to vibration strength — no extra scaling needed.

Live Status

Whatever JSON your firmware writes back over serial shows up here automatically — battery, active state, last gesture, whatever keys you send.

Payload Preview

This is exactly what gets written to the serial buffer for the ESP32's ArduinoJson decoder to pick up.

Serial Monitor

Raw TX/RX log for debugging the link.
