Gyroscope()

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

If a feature policy blocks use of a feature, it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. The Feature-Policy HTTP header article contains implementation instructions.

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 sensor.onreading 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'.
