Gyroscope.rotationRateUnbiased
var rotationRateUnbiased: Vector3;
Vector3 rotationRateUnbiased;
rotationRateUnbiased as Vector3
Description

Returns unbiased rotation rate as measured by the device's gyroscope.

The rotation rate is given as a Vector3 representing the speed of rotation around each of the three axes in radians per second. This value has been processed to remove "bias" and give a more accurate measurement. The raw value reported by the gyroscope hardware can be obtained with the rotationRate property.
