Property	Access type	Description
alpha	Read-only	The rate of rotation (in deg/s) of the host device around its Z axis, where Z is perpendicular to the screen, and positive out of the screen.
beta	Read-only	The rate of rotation (in deg/s) of the host device around its X axis, where X is in the plane of the screen, and positive towards the right hand side of the screen.

Remarks

The X axis of the host device is in the plane of the screen and is positive towards the right hand side of the screen.

The Y axis of the host device is in the plane of the screen and is positive towards the top of the screen.

The Z axis of the host device is perpendicular to the screen and is positive out of the screen.

The X, Y, and Z axes correspond to the beta, gamma, and alpha properties of the DeviceRotationRate object, respectively. Rotations use the right-hand rule, such that positive rotation around an axis is clockwise when viewed looking towards the positive direction of the axis.
