Sensor Control Summary - Epson Moverio Pro BT-2000 Developer's Manual

7.1. 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.
