The RelativeOrientationSensor() constructor creates a new RelativeOrientationSensor object which describes the device's physical orientation.

new RelativeOrientationSensor()
new RelativeOrientationSensor(options)

Options are as follows:

frequency Optional: The desired number of times per second a sample should be taken, meaning the number of times per second that the reading event will be called. A whole number or decimal may be used, the latter for frequencies less than a second. The actual reading frequency depends device hardware and consequently may be less than requested.
referenceFrame Optional: Either 'device' or 'screen'. The default is 'device'.
