[Mobile] RotationRate

I have many questions about mobile motions but I will be trying to explain my question clearly. Basicly, I try to simulate head rotation by using rotation rate. However, the things unclear for me are:

  • Is it the value provided by the gyroscope?
  • What is the FVector rotation rate returned from GetInputMotionState()? (I mean, is it a degree value or what?)
  • The coordinate system for RotationRate is the same for both Android and IOS devices?
