Gravity Vector is Fooled

Hi people,

I am currently trying to implement a basic VR head motion in my project. The problem is that I am not comfortable with the sensor values provided. For instance, I roll my camera with respect to gravity but the gravity vector is affected by the other forces as well(when I turn around myself for instance) and this causes my camera to roll even if I do not roll the phone. I could not find a way to remove those other forces effecting gravity vector. Any idea?

void APlayerVR::PerformRoll(FVector Gravity)
{
	FRotator CameraRotation = CameraComponent->GetComponentRotation();
	float CurrentRoll = CameraRotation.Roll;
	float TargetRoll = Gravity.Y * 10.0f;

	CameraRotation.Roll = FMath::Lerp(CurrentRoll, TargetRoll, 0.1f);
	CameraComponent->SetWorldRotation(CameraRotation);
}
