Magnetic Field Toolkit

@vle07

Is it possible to define absolute device orientation with the magnetometer combined with accelerometer/gravity readings, so that pitch, yaw, and roll are defined with respect to magnetic north and the earth’s gravitational field? If so, would you be willing to add a blueprint variable that contains the rotation vector of the absolute device orientation? Also, how quickly do the magnetometer readings usually respond? Thanks!

Hello vle07 and thanks for reaching out,
It is absolutely possible to get the absolute device orientation. I am adding this node to the feature backlog. Much useful for VR applications.
The magnetometer readings are instantaneous from the human point of view. Very small windowed average from the hardware. Some jitter though. Nothing smoothing can’t solve. Download the demo at https://play.google.com/store/apps/details?id=com.CeriseSoftware.MagneticFieldToolkit and you can see for yourself the responsivnes.
Best,
