Sensor control summary

The BT-2000 is equipped with an IMU (high precision, high stability inertia measurement unit), a

geomagnetic sensor, and an ALS (ambient light sensor). Tap detection and azimuth detection are

also available.

7.1.1.

IMU and the geomagnetic sensor

The BT-2000 is equipped with an IMU and a geomagnetic sensor. The IMU can detect tri-axis

acceleration and tri-axis angular velocity. The IMU allows high precision stance detection. There is

also a built-in tri-axis geomagnetic sensor which combined with the IMU allows for azimuth

calculations.

IMU sensor data can be received same as normal sensors by using Android standard API.

The following shows the specifications for the IMU and the geomagnetic sensor.
