The Gyroscope() constructor creates a new Gyroscope object which provides on each reading the angular velocity of the device along all three axes.

options Optional

Options are as follows:

frequency

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

Either 'device' or 'screen'. The default is 'device'.
