In raw sensors mode, the Tap continuously sends raw data from the following sensors:

1. Five 3-axis accelerometers (one per each finger).

   • sampled at 200Hz

   • allows dynamic range configuration (±2G, ±4G, ±8G, ±16G)

2. IMU (3-axis accelerometer + gyro) located on the thumb (available with TAP Strap 2 only).

   • sampled at 208Hz.

   • allows dynamic range configuration for the accelerometer (±2G, ±4G, ±8G, ±16G) and for the gyro (±125dps, ±250dps, ±500dps, ±1000dps, ±2000dps).

Timestamp synchronisation

Each sample (of accelerometer or IMU) is preambled with a microsecond millisecond timestamp, referenced to an internal Tap Strap clock.

...

The dynamic range of the sensors is determined by passing a three sensitivity values (by order):

1. Fingers accelerometers sensitivity -

2. IMU gyro sensitivity -

3. IMU accelerometer sensitivity -
