BNO055 Direction of Movement

[paschaef]

Hi all,

Is there a possibility to measure the direction of movement in sensor-body-coordinates with the BNO055?

Generally, the approach would be to integrate linear acceleration over time to obtain the velocity in each axis and keep track of velocity to obtain a vector of the actual movement of the sensor. However, in the datasheet of the BNO055 sensor it says integrating lineare acceleration is not a good idea:

Note: The linear acceleration signal typically cannot be integrated to recover velocity, or
double-integrated to recover position. The error typically becomes larger than the signal within
less than 1 second if other sensor sources are not used to compensate this integration error.

Is it possible to perform such a task with the BNO055? The value of the velocities is not important only the direction of movement.

Thanks for your help.

This was my initial idea to perform this task, but after reading through the data sheet I was concerned about the note of not integrating linear acceleration.

Thanks very much for clarification.
