Raw sensors

Raw mode exposes the motion sensors behind Tap’s gesture pipeline. That is useful for research, custom gesture models, and XR prototypes — not for everyday typing.

What is streamed

1. Finger accelerometers (Tap Strap / Tap Strap 2): one 3-axis sensor per finger, ~200 Hz, configurable ±2/4/8/16 g.
2. Thumb IMU (Tap Strap 2 / TapXR): accelerometer + gyro, ~208 Hz, configurable accelerometer and gyro ranges.

Samples are timestamped in milliseconds on an internal device clock. Timestamps are not synchronized to wall time by the SDK.

Scaling

Firmware sends integer LSB counts. InputModeRaw(scaled=True) multiplies by the scale factors that belong to the selected sensitivity enums, yielding mg (accelerometer) and mdps (gyro). If you scale yourself, keep scaled=False and use RawSensorsSensitivity.get_scale_factors().

You cannot change sensitivity while remaining in raw mode with a different command; leave raw mode, then re-enter with new enums.

Reference frames

Axes are defined relative to the hardware:

Developer mode

Raw streaming expects Developer mode enabled in Tap Manager. Without it, characteristics may be present but the stream may not behave as documented.
